Investment Management regulatory updates from Luxembourg.
We track 420 Investment Management updates from Luxembourg regulators, published by CSSF. The archive covers 125 reports, 92 guidance notes and 64 warnings. Most recent update: November 2026. Coverage runs from 2020 to 2026.
The CSSF publishes a consumer-facing warning about unknown persons impersonating Finare Asset Management S.A. via a fraudulent website and email address. The real firm is an investment firm and is not linked to the site. The topics are consumer fraud and identity-theft-related illicit activity.
The document presents monthly statistics on UCI net assets, market performance, net issues, and counts of registered and deregistered funds, so it is best classified as a report. It imposes no obligations and sets no dates requiring action, so urgency is null.
The text contains only a title, publication date, and a link to a PDF of the firm's submission. The firm name, State Street Global Advisors Ireland Limited, supports an Investment Management and Asset Manager classification. The consultation's subject matter is not stated in the text, so the topic is General.
The document is titled as an answer to a public consultation by Schroders Investment Management (Europe) S.A., an asset manager, and published by the CSSF. The text contains no substantive content, so the topic cannot be determined and is tagged General.
The title identifies this as the CSSF's answer to a public consultation submitted by J.P. Morgan Asset Management (Europe) SARL, which supports the policy_statement type and the Investment Management sector.
The title identifies the CSSF's answer to an EFAMA public consultation, which indicates a regulator position statement on an investment-fund matter, so Investment Management and Asset Manager are supported. The body contains no substantive content and the consultation subject is not stated, so the topic is General.
CSSF published IMMFA’s response to its consultation on enhanced weekly liquid asset (WLA) levels for money market funds, alongside final guidance issued on 30 October 2026. The guidance uses market-resilience benchmarks of 20% WLA for VNAV MMFs and 40% for public debt CNAV and LVNAV MMFs, increasing supervisory attention where funds remain below those levels even though the benchmarks do not replace the statutory MMFR minima.
Key dates
2026-05-11
European Commission published its report on the adequacy of the MMFR and identified market-resilience WLA levels of 20% for VNAV MMFs and 40% for public debt CNAV and LVNAV MMFs.
2026-06-08
CSSF launched its consultation on Guidance on Money Market Fund Weekly Liquid Asset Levels.
2026-08-03 Deadline
Deadline for stakeholders to submit responses to the CSSF consultation.
2026-10-30
CSSF published the IMMFA consultation response and final guidance, and announced a three-month implementation period.
Suggested considerations
Firms should classify each affected MMF by VNAV, public debt CNAV or LVNAV status and map the applicable 20% or 40% WLA resilience benchmark against the existing 15% or 30% MMFR minimum.
MMF managers should update liquidity-risk policies, escalation thresholds, management information and governance records to evidence enhanced vigilance when WLA approaches or falls below the relevant benchmark.
Risk teams should incorporate the 20% and 40% benchmarks into Article 28 MMFR stress-testing and assess whether investor concentration, redemption behaviour, market liquidity and portfolio composition require liquidity materially above the benchmark.
Firms should establish controls to identify periods exceeding 10 business days below the applicable benchmark and procedures for timely CSSF notification, including documented explanations, justifications and any relevant Article 28(4) or (5) remedial measures.
Boards and senior management should review whether the three-month implementation period announced by CSSF requires changes to investment guidelines, liquidity buffers, breach escalation and reporting calendars.
Compliance teams may wish to document that the resilience benchmarks are supervisory reference points rather than replacements for the MMFR statutory ratios, while recognising the CSSF’s stated intention to increase supervisory engagement for prolonged deviations.
Firms should monitor cross-border consistency with the parallel supervisory approaches of the French AMF and Central Bank of Ireland, particularly where groups manage MMFs in multiple EU jurisdictions.
What changed
The CSSF has finalised guidance, following the consultation that closed on 3 August 2026, with only slight clarifications. MMF managers are expected to incorporate 20% WLA for VNAV MMFs and 40% WLA for public debt CNAV and LVNAV MMFs into liquidity-risk frameworks and Article 28 stress-testing processes. These benchmarks sit above the existing Regulation (EU) 2017/1131 minimum WLA requirements of 15% for VNAV MMFs and 30% for public debt CNAV and LVNAV MMFs.
Compliance impact
The publication materially raises supervisory expectations for MMF liquidity management and creates a potential notification and supervisory-engagement trigger after more than 10 business days below the relevant resilience benchmark. Although it does not amend the binding MMFR minimum ratios, persistent underperformance may lead to increased CSSF scrutiny, requiring robust evidence of escalation, stress testing, governance and liquidity-management decisions.
The title identifies a CSSF answer to a public consultation submitted by the Investment Company Institute, which supports a policy_statement classification and an investment management link.
The title identifies this as the CSSF's answer to a public consultation submitted by Amundi Asset Management, which fits the policy_statement type for responses to consultations. Amundi is an asset manager, so Investment Management is the only supported sector.
The title identifies a CSSF answer to a public consultation submitted by BNP Paribas Asset Management Luxembourg, which supports policy_statement and the Investment Management sector.
On 30 October 2026, the CSSF published final guidance establishing supervisory market-resilience benchmarks for weekly liquid assets (WLA) of 20% for variable net asset value (VNAV) MMFs and 40% for public debt constant NAV (CNAV) and low-volatility NAV (LVNAV) MMFs. The guidance does not replace the binding Money Market Fund Regulation (MMFR) minima of 15% for VNAV and 30% for public debt CNAV/LVNAV funds, but it introduces enhanced monitoring, escalation and CSSF notification expectations, with a three-month implementation period.
Key dates
2026-05-11
The European Commission published its MMF adequacy report identifying market-resilience WLA benchmarks of 20% for VNAV MMFs and 40% for public debt CNAV and LVNAV MMFs, compared with MMFR minima of 15% and 30%, respectively.
2026-06-08
The CSSF launched its consultation on guidance for MMF weekly liquid asset levels.
2026-08-03 Deadline
Deadline for stakeholders to submit responses to the CSSF consultation.
2026-10-30
The CSSF published the final guidance and feedback statement and began a three-month implementation period.
2027-01-30 Deadline
Expected end of the CSSF's three-month implementation period, calculated from publication on 30 October 2026.
Suggested considerations
Firms should identify each in-scope MMF's applicable WLA benchmark, distinguishing VNAV funds from public debt CNAV and LVNAV funds, and document the classification rationale.
Managers should review daily liquidity, weekly liquidity, portfolio composition and liquidity-buffer targets against both the binding MMFR minima and the higher CSSF market-resilience benchmarks.
Risk teams should enhance monitoring and escalation procedures for WLA levels approaching or falling below 20% or 40%, including ownership, management-information frequency, escalation thresholds and evidence of reinforced decision-making.
Managers should update MMFR Article 28 stress-testing methodologies and governance to reflect the 20% VNAV and 40% public debt CNAV/LVNAV resilience levels, while retaining the existing MMFR regulatory minima and applicable ESMA stress-test requirements.
Firms should establish a documented process for counting consecutive business days below the applicable benchmark and for notifying the CSSF after more than 10 business days or when a prolonged or substantial deviation is expected.
Where stress testing identifies vulnerability, compliance and risk functions should assess whether Article 28(4) immediate notification, Article 28(5) reporting and an action plan are required.
Managers should prepare records explaining any sustained deviation, including investor-liability characteristics, redemption patterns, liquidity-risk-system outputs, stress-test results and remedial measures, because the CSSF may increase supervisory scrutiny and review available information.
Firms should assess whether prospectus disclosures, internal liquidity-risk policies, investment guidelines, delegation arrangements and board or conducting-officer reporting need updating during the three-month implementation period.
What changed
The final guidance follows the CSSF consultation launched on 8 June 2026 and contains only slight clarifications after stakeholder feedback. MMF managers are expected to treat 20% WLA for VNAV funds and 40% WLA for public debt CNAV and LVNAV funds as market-resilience reference levels within their liquidity-risk-management and stress-testing frameworks. When WLA approaches or falls below the applicable level, managers should apply enhanced vigilance, timely escalation and reinforced internal decision-making.
Compliance impact
The guidance is supervisory guidance rather than a new MMFR statutory minimum, but it materially raises the expected operating buffer above the binding 15% VNAV and 30% public debt CNAV/LVNAV thresholds. Persistent shortfalls can lead to CSSF notification, heightened supervisory engagement and review; stress-test vulnerabilities can additionally activate the existing Article 28(4) and (5) notification, reporting and action-plan consequences.
The title 'Answer to the public consultation' indicates a settled regulator response, so policy_statement fits. The Investment Management sector and Asset Manager firm type rest only on the named firm, Aberdeen Investments.
CSSF published ALFI’s response to its consultation on guidance for weekly liquid asset levels of money market funds (MMFs), alongside final guidance on 30 October 2026. The guidance introduces supervisory benchmarks of 20% weekly liquid assets (WLA) for variable net asset value (VNAV) MMFs and 40% for public debt constant net asset value (CNAV) and low volatility net asset value (LVNAV) MMFs; these are intended as resilience benchmarks rather than new statutory minimums, but persistent deviations can trigger notification and intensified CSSF scrutiny.
Key dates
2026-08-03 Deadline
Deadline for stakeholders to submit responses to the CSSF consultation on the proposed MMF WLA guidance.
2026-10-30
CSSF published the final MMF WLA guidance, feedback statement and consultation responses, including ALFI’s response.
Suggested considerations
Firms should classify each in-scope MMF as VNAV, public debt CNAV or LVNAV and map the applicable 20% or 40% WLA resilience benchmark against the fund’s existing 15% or 30% MMFR minimum.
MMF managers should review liquidity risk-management frameworks, redemption assumptions, escalation thresholds, governance documentation and management-information reporting to demonstrate how the relevant benchmark is considered as a risk-management reference point rather than treated automatically as a statutory minimum.
Managers should incorporate the 20% and 40% benchmarks into Article 28 MMFR stress-testing methodology, scenario analysis and board or governing-body reporting, while documenting fund-specific reasons for maintaining lower or higher WLA levels where appropriate.
Firms should establish reliable daily monitoring of WLA, a process for identifying periods exceeding 10 business days below the relevant benchmark, and controls for escalating prolonged or substantial deviations to senior management and the CSSF.
Compliance teams may wish to prepare the information expected in a CSSF notification, including the duration and magnitude of the deviation, its cause, investor and redemption characteristics, stress-test results, liquidity-management actions and the rationale for the manager’s response.
Boards and depositaries should review whether oversight records, challenge processes and valuation or liquidity controls adequately address the potential supervisory consequences of persistent benchmark breaches.
Firms should assess the interaction with Circular CSSF 26/911 and the 2025 ESMA MMF stress-test guidelines, which apply to CSSF-supervised MMFs and Luxembourg managers from the 30 June 2026 reporting date onward.
Managers should avoid presenting the resilience benchmarks to investors as amended legal minimums unless the fund’s governing documents, disclosures or risk limits separately require that treatment; market commentary from respondents indicated concern that the 10-business-day trigger could operate as a de facto limit in practice.
What changed
The final guidance retains the European Commission’s market-resilience WLA benchmarks: 20% for VNAV MMFs and 40% for public debt CNAV and LVNAV MMFs. These levels sit above the Money Market Funds Regulation (Regulation (EU) 2017/1131) minimum WLA requirements of 15% for VNAV MMFs and 30% for public debt CNAV and LVNAV MMFs; the existing daily liquid asset minimums remain 7.5% and 10%, respectively.
Compliance impact
The measure does not create new statutory MMFR liquidity minima, but it creates clear supervisory expectations around liquidity monitoring, stress testing, escalation and CSSF engagement. A failure to explain a WLA level below 20% or 40% for more than 10 business days may lead to increased supervisory scrutiny and could expose weaknesses in the fund’s liquidity-risk governance or Article 28 stress-testing framework.
The CSSF has finalised guidance requiring Luxembourg-authorised money market funds and their managers to use enhanced weekly liquid asset benchmarks of 20% for variable net asset value (VNAV) MMFs and 40% for public debt constant net asset value (PD CNAV) and low-volatility net asset value (LVNAV) MMFs. The benchmarks do not replace the binding minimum ratios in Regulation (EU) 2017/1131, but falling below them triggers enhanced vigilance, escalation, supervisory notification in specified circumstances and potentially further CSSF engagement.
Key dates
2026-06-08
CSSF consultation on proposed guidance was published.
2026-08-03 Deadline
Deadline for stakeholder responses to the consultation.
2026-10-30
CSSF published the final guidance and confirmed a three-month implementation period.
2027-01-30 Deadline
End of the three-month implementation period calculated from publication of the final guidance; affected firms should have implemented the guidance by this date.
Suggested considerations
Firms should identify each affected MMF's classification under Regulation (EU) 2017/1131 and map its current WLA and DLA monitoring against both the binding MMFR minima and the applicable 20% or 40% market-resilience benchmark.
Compliance and risk teams may wish to update liquidity-risk policies, escalation thresholds, governance papers and management information to address enhanced vigilance when WLA approaches or falls below the benchmark.
Managers should incorporate the 20% VNAV and 40% PD CNAV/LVNAV levels into Article 28 MMFR stress-testing methodology, scenarios, documentation and vulnerability-remediation processes.
Firms should establish controls to identify a breach lasting more than 10 business days and to prepare timely CSSF notifications containing the causes, expected duration, justification and relevant Article 28(4) and (5) measures.
Boards, conducting officers and relevant risk committees may wish to review whether internal decision-making and escalation procedures are sufficiently reinforced for prolonged or substantial deviations.
Firms should distinguish clearly in investor, regulatory and internal reporting between binding MMFR liquidity minima and the CSSF's supervisory market-resilience benchmarks, since the latter are not new statutory minimum ratios.
Luxembourg MMF managers should assess operational readiness during the three-month implementation period and retain evidence of implementation, monitoring and supervisory communications.
What changed
The final guidance largely confirms the consultation proposal and introduces only slight clarifications. MMF managers should incorporate market-resilience WLA levels of 20% for VNAV MMFs and 40% for PD CNAV and LVNAV MMFs into liquidity-risk management and Article 28 MMFR stress-testing processes. These levels operate as supervisory and risk-management benchmarks above the MMFR minimum WLA ratios of 15% for VNAV MMFs and 30% for PD CNAV and LVNAV MMFs; the minimum daily liquid asset ratios remain 7.5% for VNAV MMFs and 10% for PD CNAV and LVNAV MMFs.
Compliance impact
The guidance is supervisory guidance rather than an amendment to Regulation (EU) 2017/1131, so falling below 20% or 40% is not automatically a breach of a new statutory liquidity minimum. It nevertheless creates a concrete supervisory expectation: prolonged or unjustified shortfalls can lead to CSSF information requests, intensified supervisory engagement and scrutiny of the manager's liquidity-risk governance, stress testing and measures taken under Article 28 MMFR.
The content is a title, date, and form reference only. The form is a CSSF operational notification template for IFMs (investment fund managers) to report the cessation of a tied agent arrangement, so it is classed as a regulatory notice with Investment Management as the sector and Reporting & Disclosure as the topic.
The document is the CSSF's monthly basic statistics publication on undertakings for collective investment (UCIs), published as an XLSX dataset. It is a report of data, so it is classified as report.
The document is a CSSF monthly statistics publication reporting net assets of UCIs as at 30 September 2026. It contains only a title, date, and links to statistics, with no obligations or policy content.
The document is a CSSF quarterly statistics publication showing net assets (EUR bn), number of UCIs, and number of fund units from December 2022 to September 2026.
The document is a CSSF monthly statistics publication (xlsx data tables as of 30 September 2026) covering UCI fund units by reference currency. It is data only, with no rules, deadlines, or supervisory expectations, so it is classed as a report, tagged to investment management, and given null urgency and a score of 1...
The publication is a monthly statistics release (data as at 30 September 2026, provided as an xlsx file), which matches the report type. The text supports only an investment-fund context, so Investment Management is the sector. The text contains no specific compliance topic, so General is used.
The title 'Number of UCIs' and the reference to statistics support a report classification and an Investment Management sector tag. The rest of the content is website navigation and cookie text, so no specific topic is supported and 'General' is used.
The document is a CSSF statistics publication (spreadsheets of net assets by investment policy as at 30 September 2026). It is data rather than a rule, guidance, or consultation, so it carries no obligation or deadline. It relates to UCIs, so Investment Management and Asset Manager are the relevant tags.
The document is a CSSF public warning about fraudulent activity by 'Golden Springs Funds SCSp', an entity with no Luxembourg authorisation, and lists its alleged address, website, email, and phone number.
The CSSF warns consumers that unknown persons are impersonating LaCambre Asset Management Luxembourg S.à r.l. through a specific website, email address and alleged registered office. The text concerns identity theft and illicit activity, so the financial crime and consumer protection topics apply.
CSSF confirms that the EU regulatory framework for the move from T+2 to T+1 securities settlement is complete, with T+1 scheduled to apply on 11 October 2027. The first binding implementation milestone arrives on 7 December 2026, when investment firms and their professional clients must use electronic, standardised and machine-readable processes for allocations and confirmations; market commentary indicates that manual, telephone, fax, spreadsheet and email-based workflows may no longer be adequate.
Key dates
2026-12-07 Deadline
First phased requirements apply to investment firms and their clients for allocations and confirmations, including electronic, standardised, international-standard and machine-readable communications except during temporary technical disruptions.
2027-07-01 Deadline
Second phased implementation deadline under the amended settlement-discipline framework.
2027-10-11 Deadline
EU securities markets move from the standard T+2 settlement cycle to T+1; the final phased settlement-discipline requirements apply.
Suggested considerations
Firms should map every allocation, confirmation, matching and settlement-instruction process affected by the amended settlement-discipline RTS and identify manual, non-standardised or non-machine-readable steps.
Compliance teams may wish to confirm that electronic, standardised communication channels and international messaging standards are available to the firm and its professional clients before 7 December 2026.
Firms should consider implementing trade-date controls, internal cut-offs, automated alerts, escalation procedures and exception reporting to identify transactions at risk of missing the applicable allocation and confirmation deadline.
Investment firms may wish to review client onboarding and contractual documentation to ensure that professional clients provide complete settlement details and use compatible communication channels and formats.
Operations and technology teams should test end-to-end connectivity, message formats, reference data, settlement instructions, matching, foreign-exchange funding, securities lending, collateral and asset-servicing workflows across the entire trading and settlement ecosystem.
Firms should assess readiness not only within their own organisation but also across brokers, custodians, clients, fund administrators, CSDs, settlement agents and other outsourced providers.
Firms should establish a phased implementation plan covering the 7 December 2026, 1 July 2027 and 11 October 2027 milestones, with evidence of testing, issue remediation and management oversight.
Compliance teams may wish to monitor further ESMA and CSSF supervisory communications because ESMA and national competent authorities have indicated that they will monitor compliance with the new obligations.
What changed
Amended settlement-discipline regulatory technical standards under Commission Delegated Regulation (EU) 2018/1229 introduce phased requirements supporting the EU T+1 transition. From 7 December 2026, investment firms and their clients must use electronic, standardised communication channels and international messaging standards for allocations and confirmations, with machine-readable communication required except during temporary technical disruptions.
Compliance impact
The update signals binding operational and technology requirements rather than merely voluntary preparation, with the first compliance milestone less than two months after the CSSF publication. Failure to automate and standardise post-trade communications could cause settlement delays or fails and expose firms to supervisory scrutiny, particularly as ESMA and national competent authorities move to monitor compliance.
Administrative sanction imposed on VP Fund Solutions (Luxembourg) SA
Why this matters
The document is a CSSF administrative sanction imposed on VP Fund Solutions (Luxembourg) SA, a fund services provider, so it is enforcement and maps to Investment Management. The text does not state the nature of the violation, so the topic is General.
The CSSF warns consumers that unknown persons are misusing the former name 'Arche Associés S.A.' of CORIENT S.A., an investment firm, through a fraudulent website. The content supports financial crime (identity theft and fraud) and an investment firm as the impersonated entity.
under Article 13(2a) of the Law of 2013 and/or Article 111(2) of the Law of 2010
Why this matters
The CSSF is notifying regulated IFMs of a new dedicated form that must be completed before first-time white-label activity, under Article 13(2a) of the 2013 Law and Article 111(2) of the 2010 Law. This is an operational notice to regulated entities with an obligation attached, so an urgency is assigned.
The text is primarily a title, a publication date, and a link to an XLSX form specifying information an IFM must provide to the CSSF before performing white-label business under Article 13(2a) of the 2013 Law and/or Article 111(2) of the 2010 Law.
CSSF has highlighted AMLA’s submission of three draft Regulatory Technical Standards to the European Commission covering business relationships and occasional transactions, customer due diligence, and group-wide AML/CFT arrangements. The standards are not yet final or applicable, but they are expected to provide materially more operational detail under Regulation (EU) 2024/1624, with AMLA proposing a six-month transition after the final RTS enter into force.
Key dates
2026-02-09
AMLA opened the public consultation on the draft RTS concerning business relationships, occasional and linked transactions, lower thresholds, and customer due diligence.
2026-04-16
AMLA opened the public consultation on the draft RTS concerning group-wide requirements and additional measures for subsidiaries and branches in third countries.
2026-05-08
Public consultation closed for the business-relationship, transaction and customer-due-diligence draft RTS.
2026-06-15
Public consultation closed for the group-wide arrangements and third-country legal-impediment draft RTS.
2026-10-01
AMLA announced that it had finalised the three draft RTS and submitted them to the European Commission for formal adoption.
2026-10-07
CSSF published its communiqué drawing Luxembourg professionals’ attention to the draft RTS and recommending preparatory gap analysis and control work.
Suggested considerations
Compliance teams may wish to complete a gap analysis against the AMLA final reports, particularly for customer and beneficial-owner information, verification sources, electronic identification, non-face-to-face onboarding and PEP screening.
Firms should consider mapping current customer journeys and transaction-monitoring logic to the proposed distinction between business relationships, occasional transactions and linked transactions.
Firms may wish to identify products, sectors and transaction types that could be affected by lower CDD thresholds for higher-risk activities, while avoiding reliance on unfinalised monetary thresholds.
Financial groups should consider reviewing group-wide AML/CFT governance, risk assessments, policies, internal controls, training and secure information-sharing arrangements, including structures involving common ownership, management, compliance control, networks or partnerships.
Groups with branches or subsidiaries in third countries should consider inventorying legal impediments to applying EU AMLR and group policies and preparing escalation, risk-mitigation and supervisory-response procedures.
IT and operations teams may wish to assess changes needed for customer-data fields, linked-transaction detection, identity-verification evidence, electronic identification and intra-group information exchange.
Firms should monitor the European Commission’s adoption process and the Official Journal publication because the final text, effective date and any amendments remain unknown; preparatory work should be calibrated to the proposed six-month transition period rather than treated as a current binding deadline.
What changed
The draft RTS under Article 19(9) of Regulation (EU) 2024/1624 would establish criteria for distinguishing business relationships, occasional transactions and linked transactions, and would identify high-risk obliged entities, sectors or transactions for which lower CDD thresholds should apply. The draft RTS under Article 28(1) would specify information and verification requirements for standard, simplified and enhanced CDD, including reliable and independent verification sources, electronic identification means, qualified trust services, non-face-to-face verification, and relevant treatment...
Compliance impact
The immediate impact is preparatory rather than a current new compliance deadline, because the drafts remain subject to possible Commission amendment and Official Journal publication. The likely impact is significant: firms may need changes to onboarding, CDD, transaction classification and monitoring, identity verification, group governance, data sharing and third-country legal-impediment controls, with the proposed six-month transition limiting the available implementation window after entry into force.
This is a feedback report published by the CSSF on 5 October 2026 regarding Circular CSSF 24/856, which entered into force on 1 January 2025 and governs investor protection in case of NAV calculation errors and non-compliance at UCI level.
Administrative sanction imposed on an investment fund manager
AI Analysis
On 9 July 2026, the CSSF imposed an anonymous administrative fine of EUR 71,500 on a Luxembourg Chapter 15 management company authorised as an AIFM. The sanction followed an on-site inspection that found inadequate periodic, risk-based due diligence and independent monitoring of delegated portfolio managers, including weaknesses in best-execution and broker-selection oversight; independent market commentary indicates that delegation oversight remains a recurring CSSF enforcement priority for investment fund managers.
Key dates
2024-09-18
The CSSF began the on-site inspection of the manager’s corporate governance framework.
2024-10-10
The CSSF completed the on-site inspection that identified persistent internal-governance and delegation-oversight deficiencies.
2026-07-09
The CSSF imposed the total administrative fine of EUR 71,500.
2026-10-05
The CSSF published the sanction decision anonymously.
Suggested considerations
Compliance teams may wish to map every delegated portfolio manager to a documented, risk-based periodic due-diligence plan and verify that reviews are renewed at an appropriate frequency under the manager’s risk matrix.
Firms should consider documenting assessments of each delegate’s legal and contractual compliance, control environment, best-execution procedures, broker-selection processes and relevant reporting capabilities.
Firms should consider testing whether delegate oversight includes independent verification rather than relying exclusively on confirmations, questionnaires or representations from portfolio managers.
Management companies may wish to establish measurable monitoring indicators, thresholds, exception escalation and evidence-retention arrangements for best-execution oversight, consistently with the applicable delegation procedures and CSSF Circular 18/698.
Firms should consider reviewing delegation contracts, governance reporting and action plans to demonstrate that the supervisory framework protects the interests of the funds and investors and that monitoring of delegated activities remains with the manager.
Compliance teams may wish to benchmark their controls against the CSSF’s broader thematic and enforcement messaging; independent commentary indicates that inadequate delegate supervision, weak quantitative monitoring and insufficient evidence of independent controls are recurring supervisory concerns.
What changed
This is an enforcement action rather than a new rule. The CSSF applied Article 110(1)(b) and (f), and Articles 148(2)(j) and 148(4)(e), of the amended Law of 17 December 2010 relating to undertakings for collective investment, together with Article 18(1)(e) and (f), and Article 51(1) and (2), of the amended Law of 12 July 2013 on alternative investment fund managers. The fine comprised EUR 47,320 under the 2010 Law and EUR 24,180 under the AIFM Law.
Compliance impact
The sanction demonstrates that delegation remains a direct supervisory responsibility of the investment fund manager: outsourcing portfolio management does not outsource oversight, best-execution assessment or independent monitoring. Although the fine was imposed on one anonymised manager and remedial actions were considered, the CSSF’s findings create a material governance, investor-protection and enforcement precedent for Luxembourg IFMs using delegated portfolio managers.

on requirements on the use of ICT third-party services for Financial Entities subject to the Digital Operational Resilience Act (DORA)
AI Analysis
Circular CSSF 25/882 establishes Luxembourg-specific requirements for DORA financial entities using ICT third-party services, including professional-secrecy safeguards, prior notification, annual registers of information and cloud-governance responsibilities. Circular CSSF 26/915, effective 27 August 2026, expands the circular to qualifying third-country branches in Luxembourg, with immediate effect and no separate transition period.
Key dates
2025-01-17
DORA became applicable to in-scope financial entities, according to the CSSF implementation communication referenced by Circular CSSF 25/882.
2025-04-09
Circular CSSF 25/882 was published and applied with immediate effect.
2025-04-01 Deadline
The first exceptional CSSF register submission window opened for arrangements contracted up to 31 March 2025.
2025-04-15 Deadline
The first exceptional CSSF register submission window closed.
2026-08-27
Circular CSSF 26/915 was published and immediately amended Circular CSSF 25/882 to include qualifying third-country branches in Luxembourg.
2027-03-31 Deadline
Latest date for submission of the register covering arrangements contracted through the end of 2026, under the recurring annual window running from 28 February to 31 March of the following year.
Suggested considerations
Firms should assess whether Luxembourg third-country branches now fall within the amended scope by comparing the branch’s undertaking and head-office activities with the DORA categories in Article 2(1)(a) to (t) and documenting the conclusion.
Compliance teams may wish to inventory all ICT third-party arrangements, including digital, data, cloud, infrastructure and operational services that may not qualify as outsourcing under prior CSSF terminology.
Firms should consider updating ICT third-party approval workflows so arrangements supporting critical or important functions are notified through the CSSF-prescribed form at least three months before commencement, or one month before commencement where the provider is an eligible Luxembourg support PFS.
Firms should maintain an accurate register of information at individual, sub-consolidated and consolidated levels, with controls for prompt correction when requested by the CSSF and the ability to provide the register outside the annual submission window.
Compliance and outsourcing teams may wish to reassess contractual access to professional-secrecy data against Article 41(2a) LFS or Article 30(2a) LPS and verify that Luxembourg ICT management or operations providers hold the required Article 29-3 LFS authorisation or qualify for an applicable exception.
Firms using cloud services should confirm that the resource operator has designated a suitably qualified cloud officer and that internal cloud, information-security and third-party oversight responsibilities are clearly allocated.
Third-country branches should consider implementing the requirements immediately because Circular CSSF 26/915 provides no transition period, while preserving evidence of governance, notification and register controls for supervisory review.
What changed
Circular CSSF 26/915 includes in Circular CSSF 25/882’s scope all Luxembourg third-country branches of undertakings covered by the specified DORA financial-entity categories where the head office would qualify as a DORA entity under Article 2(1)(a) to (t) in the relevant third country. The requirements apply to ICT services broadly, not only arrangements that meet a traditional outsourcing definition.
Compliance impact
The amendment materially increases the population subject to Luxembourg’s ICT third-party controls because qualifying third-country branches must comply immediately, without a transition period. Non-compliance may leave arrangements formally untreated as notified and expose firms to supervisory measures, binding measures and administrative sanctions, while firms remain fully responsible for compliance and for the resilience and governance of their ICT third-party providers.
Application of the Joint ESA Guidelines on the estimation of aggregated annual costs and losses caused by major ICT-related incidents under Regulation (EU) 2022/2554 (JC 2024 34)
AI Analysis
CSSF Circular 25/892 applies the ESAs’ Joint Guidelines JC/GL/2024/34 for estimating aggregated annual costs and losses from major ICT-related incidents under Article 11(10) and (11) of DORA. Circular 26/915, issued on 2026-08-27, immediately extends that framework to qualifying Luxembourg branches of third-country undertakings, while leaving the underlying methodology unchanged.
Key dates
2025-05-19
The Joint ESA Guidelines JC/GL/2024/34 apply at ESA level.
2025-05-31
Circular CSSF 25/892 applies to its original in-scope Luxembourg entities, excluding DORA microenterprises.
2026-08-27
Circular CSSF 26/915 is issued and applies with immediate effect, bringing qualifying Luxembourg third-country branches into the scope of Circular CSSF 25/892.
Suggested considerations
Compliance teams may wish to determine whether each Luxembourg entity or third-country branch falls within the amended scope, including whether a third-country head-office undertaking would qualify under DORA Article 2(1)(a) to (t).
Firms should consider documenting their microenterprise analysis against DORA Article 3(60), including the fewer-than-10-employees and EUR 2 million annual turnover and/or balance-sheet-total thresholds, while noting that the DORA definition excludes trading venues, central counterparties, trade repositories and central securities depositories from the microenterprise exemption.
Firms should consider maintaining an incident-level ledger linking major ICT-related incidents, DORA final-report reference codes, gross costs, losses, provisions, recoveries and subsequent adjustments.
Finance, operational-risk and ICT-incident teams may wish to agree whether the firm will use a completed calendar year or completed accounting year as its reference basis and establish controls to apply that basis consistently.
Firms should consider reconciling estimates to financial-statement or supervisory-reporting data where available, while retaining documented estimation methodology and assumptions where accurate data is unavailable.
Firms should consider tracking quantifiable financial impacts from prior-year major incidents because those impacts may need to be included in a later reference year without reopening the original final incident report.
Third-country branches may wish to confirm reporting ownership and data availability with their head office, because the amended CSSF scope is at branch level but the required cost and loss information may arise across the undertaking.
Compliance teams may wish to monitor CSSF communications for a specific request, reporting channel and submission deadline; the circular itself establishes an upon-request obligation rather than a fixed automatic annual filing deadline.
What changed
From 2025-05-31, in-scope Luxembourg financial entities other than DORA microenterprises must be able, upon CSSF request, to provide an entity-level estimate of aggregated annual costs and losses arising from major ICT-related incidents. The estimate must use the ESA common template and identify each relevant incident by the same reference code used in its DORA final incident report.
Compliance impact
The requirement is operationally significant because firms must preserve incident-level financial-impact data, distinguish gross costs from recoveries and retain historical linkage to DORA final incident reports, even though submission occurs only upon competent-authority request. The ESAs’ approach does not impose a minimum cost threshold: every incident classified as major must be covered, irrespective of the classification trigger, increasing the importance of coordination between ICT, operational risk, finance and regulatory reporting teams.
on reporting of major ICT-related incidents and significant cyber threats under the Digital Operational Resilience Act (DORA)
AI Analysis
CSSF Circular 25/893 establishes the Luxembourg reporting process for major ICT-related incidents and significant cyber threats under Regulation (EU) 2022/2554 (DORA), replacing the former CSSF 24/847 framework for DORA entities and extending the same framework to payment service providers outside DORA. The 27 August 2026 update, issued through Circular CSSF 26/915 (although the page title refers to 25/915), expressly brings qualifying Luxembourg branches of third-country financial entities within the DORA-related scope, increasing the population required to maintain rapid, event-specific reporting capability.
Key dates
2025-01-17
DORA provisions became applicable to financial entities in scope and supervised by the CSSF.
2025-05-28
Circular CSSF 25/893 was published and established the Luxembourg DORA incident and significant cyber-threat reporting modalities.
2025-11-28 Deadline
End of the six-month transition period granted to payment service providers outside DORA for implementation of the Circular 25/893 framework.
2026-08-27
Circular CSSF 26/915 was published and the 25/893 page was updated to clarify DORA applicability to qualifying third-country branches in Luxembourg; the amendment applies immediately.
Suggested considerations
Compliance teams may wish to confirm the entity-by-entity scope analysis against DORA Article 2, including whether a Luxembourg third-country branch is covered following the 27 August 2026 clarification.
Firms should consider documenting incident-classification criteria and decision records against Commission Delegated Regulation (EU) 2024/1772, including the quantitative thresholds for clients, transactions, duration, geographical spread, data loss, economic impact and reputational impact.
Firms should consider testing an escalation timetable that supports classification, initial notification within four hours and no later than 24 hours after awareness, the 72-hour intermediate report and the one-month final report.
PSPs outside DORA may wish to update policies so that all ICT-related incidents, rather than only payment-service incidents, are assessed under the DORA framework and to verify that the six-month transition requirements were completed by 28 November 2025.
Firms should consider ensuring that eDesk access, authorised users, templates, internal approvals and S3 API connectivity are operational before an incident occurs.
Incident-response procedures may wish to prohibit aggregation of separate major incidents where the CSSF reporting process requires event-specific submissions and should assign ownership even where reporting support is outsourced.
Third-country branches may wish to align their Luxembourg reporting playbooks, head-office escalation arrangements and local CSSF contacts with the immediate-effect scope clarification.
Firms should consider retaining evidence of classification, notification times, report versions, management approvals and communications with ICT third parties to demonstrate timely compliance.
What changed
DORA financial entities supervised by the CSSF must classify ICT-related incidents using the criteria and thresholds in Commission Delegated Regulation (EU) 2024/1772 and report each major ICT-related incident using the DORA reporting templates and procedures. Reporting is phased: an initial notification is generally due within four hours after classification as major and in any event no later than 24 hours after the entity becomes aware of the incident; an intermediate report is generally due within 72 hours after the initial notification; and a final report is generally due within one month...
Compliance impact
The framework creates time-critical supervisory reporting obligations with potentially material consequences for firms unable to classify or notify major incidents accurately and promptly; the regulated entity remains accountable even when submission is delegated. The 2026 clarification is particularly significant for third-country branches because it removes scope uncertainty and requires immediate integration of local branch incident reporting into DORA governance and response arrangements.
CSSF Circular 22/806 has been updated to reflect Circular 25/883 and the 27 August 2026 Circular 26/915. The framework now distinguishes between ICT outsourcing governed primarily by DORA and business-process outsourcing governed by Circular 22/806, while confirming that DORA applies to qualifying Luxembourg branches of third-country financial entities; this materially affects outsourcing inventories, contractual controls, registers of information and supervisory reporting.
Key dates
2022-04-22
Circular CSSF 22/806 was published and replaced or amended specified earlier CSSF and IML outsourcing, governance and control circulars.
2022-06-30

2025-04-09
Circular CSSF 25/883 was published; the amended Circular 22/806 applies to outsourcing arrangements entered into, reviewed or amended on or after this date.
2025-12-17
The European Commission confirmed that DORA also applies to qualifying third-country branches in an EU Member State where the third-country head-office entity would fall within DORA Article 2(1)(a) to (t).
2026-08-27
Circular CSSF 26/915 was published and the CSSF webpage consolidated the amended version of Circular 22/806, confirming the DORA treatment of qualifying Luxembourg third-country branches.
Suggested considerations
Firms should map each outsourcing and third-party technology arrangement against the applicable regime: DORA, Circular 22/806 business-process outsourcing requirements, or the full Circular 22/806 framework for non-DORA entities.
Compliance teams may wish to review whether Luxembourg third-country branches have a head-office activity that corresponds to a DORA Article 2(1)(a) to (t) financial entity and document the resulting DORA scope assessment.
Firms should update outsourcing policies, risk assessments, governance approvals, materiality or criticality assessments, due-diligence files, monitoring controls and exit strategies to reflect the split between DORA ICT third-party risk management and Circular 22/806 business-process outsourcing.
Firms should maintain or update the DORA register of information for ICT third-party arrangements where DORA applies, and reconcile it with the outsourcing inventory and CSSF notification processes.
Firms should review legacy cloud contracts and remove reliance on the repealed Circular 22/806 EEA-law and EEA-resilience clauses where DORA is the applicable ICT third-party regime, while retaining contract terms needed to satisfy DORA and any applicable national requirements.
Non-DORA entities should consider whether their existing contracts still address Circular 22/806 requirements for access and audit rights, sub-outsourcing, confidentiality, data location, business continuity, termination and exit.
Management companies authorised solely under Article 125-1 should consider retaining the full Circular 22/806 control framework for ICT outsourcing rather than assuming that DORA displaces it.
Firms should assess whether outsourcing arrangements entered into, reviewed or amended from 9 April 2025 require remediation or re-papering under the amended framework.
What changed
Circular 25/883 amended Circular 22/806 following DORA Regulation (EU) 2022/2554 becoming applicable on 17 January 2025. For entities subject to DORA, the ICT-outsourcing provisions of Circular 22/806 were largely repealed or displaced by DORA's ICT third-party risk-management requirements, while Circular 22/806 remains applicable to business-process outsourcing.
Compliance impact
The impact is high for firms with complex ICT and outsourcing models because misclassification can lead to the wrong contractual, governance, register and notification framework, and because DORA brings direct requirements for ICT third-party risk management and supervisory oversight. Independent market commentary from EY, Deloitte, Baker McKenzie and Luxembourg industry bodies reads the amendments as a practical division between DORA-regulated ICT services and Circular 22/806 business-process outsourcing, with particular remediation needs for investment managers, non-DORA entities and...

The CSSF is formally drawing attention to the CNC Q&A 26/038, which provides detailed interpretative guidance on the **new accounting regime introduced by the Law of 7 August 2023** for large not‑for‑profit associations, public‑utility associations and foundations. This matters for compliance teams because these entities are now aligned with the accounting regime for “medium‑sized undertakings” under Luxembourg company law, with specific obligations on annual accounts formats, filing, and chart‑of‑accounts choices that require governance, process and system changes.
Key dates
07 August 2023
- Law of 7 August 2023 introducing the new accounting regime for associations and foundations enters into force and defines classification as “small associations”, “medium‑sized associations” and “large associations” with corresponding accounting obligations
Autumn 2026
- CNC plans to publish an accounting guide dedicated to the new accounting regime for ASBLs classified as small, medium‑sized and large associations, and associations recognised as being of public utility
04 August 2026
- CSSF press release is published, formally drawing supervisory attention to CNC Q&A 26/038 and the related upcoming CNC accounting guide
Suggested considerations
Identify all Luxembourg associations, public‑utility associations and foundations within or related to the group that are impacted by the Law of 7 August 2023 and confirm their size classification (small, medium‑sized, large) and whether they fall under the “medium‑sized undertakings” regime.
Review existing accounting policies, charts of accounts and annual accounts formats for affected entities to ensure alignment with LRCS statutory layouts, including non‑abridged balance sheet, appropriate profit and loss format, and required notes disclosures.
Decide at governing‑body level whether each affected entity will voluntarily adopt the PCN or maintain an internal chart of accounts, documenting the rationale, governance approvals and compliance impacts of the chosen option.
Where PCN is not adopted, design, implement and document a robust mapping from the internal chart of accounts to the statutory LRCS balance sheet and profit and loss layouts, ensuring audit‑ready documentation and traceability.
Update accounting systems and reporting tools for affected entities to support LRCS statutory layouts, consistent layout adaptations, and classic‑format filing with the RCS, including necessary changes to interfaces and data capture.
What changed
- Large associations, associations recognised as being of public utility and foundations are now subject to the accounting regime applicable to “medium‑sized undertakings” under the amended...
Annual accounts for affected entities must include a non‑abridged balance sheet, a profit and loss account (at least in abridged format), and notes to the accounts containing disclosures required by...

Large associations, public‑utility associations and foundations remain exempt from the mandatory use of the Standard Chart of Accounts (Plan Comptable Normalisé – PCN) and from eCDF standard data...
Affected entities may voluntarily adopt the PCN; if they do not adopt PCN, they must maintain an internal chart of accounts and ensure robust, documented mapping between internal accounts and...
Compliance impact
Non‑compliance may result in defective or non‑compliant annual accounts filings, potential rejection or queries from the RCS, and heightened supervisory scrutiny by the CSSF where the entities are linked to regulated groups, with knock‑on effects on group reporting and reputational risk. For larger public‑interest or group‑related entities, persistent non‑compliance could trigger audit qualifications and regulatory concerns about governance and internal control over financial reporting.
The CSSF is formally drawing attention to CNC Q&A 26/038, which provides detailed interpretative guidance on the **new accounting regime introduced by the Law of 7 August 2023** for large not‑for‑profit associations, public‑utility associations and foundations. This matters for compliance teams because these entities are now subject to annual accounts obligations aligned with the regime for “medium‑sized undertakings” under the Luxembourg commercial companies law, with specific rules on formats, exemptions from PCN/eCDF, and forthcoming detailed guidance for all association size categories.
Key dates
01 January 2023
- Earliest financial year start date from which adjusted size criteria under Articles 35 and 47 LRCS may be applied to undertakings and groups, which indirectly affects categorisation and accounting obligations of entities subject to commercial‑law size criteria
07 August 2023
- Law of 7 August 2023 introducing the new accounting regime for associations and foundations is adopted, setting the legal basis for reclassification and annual accounts obligations
01 January 2024
- Default application date of the adjusted LRCS size criteria for undertakings and groups where early application from 01 January 2023 is not chosen
Financial year 2025
- New LRCS size thresholds start to determine the categorisation of pre‑existing Luxembourg undertakings and, by analogy, influence assessments of “medium‑sized” status relevant to associations
Autumn 2026
- CNC plans to publish an accounting guide dedicated to the new accounting regime for not‑for‑profit associations (ASBLs) classified as small, medium‑sized and large, as well as public‑utility associations and foundations
Suggested considerations
Identify whether the organisation qualifies as a large association, an association recognised as being of public utility or a foundation under the Law of 7 August 2023, and document the classification decision with reference to Articles 18, 36 and 52 of that law.
Update internal accounting policies to require annual accounts to be prepared in accordance with the regime for undertakings referred to in Article 47 LRCS, including minimum content (balance sheet, profit and loss account and notes) and disclosure requirements.
Decide formally whether to adopt the PCN on a voluntary basis or to maintain an internal chart of accounts, and record this decision in accounting governance documents approved by the board or governing body.
Where PCN is not adopted, design and implement a detailed and documented mapping from internal general ledger accounts to LRCS statutory balance sheet and profit and loss layouts to ensure accurate preparation and filing of annual accounts.
Review and, where necessary, redesign annual accounts templates to comply with LRCS layouts while making only permitted adaptations (for example, titles and subtotals) that maintain clarity, comparability and consistency over time.
What changed
- Large not‑for‑profit associations, associations recognised as being of public utility and foundations are required to prepare annual accounting documents consisting at a minimum of annual accounts...
These entities fall within the regime applicable to “medium‑sized undertakings”, which drives the required content and level of detail of their annual accounts (balance sheet, profit and loss account...
The law and the CNC Q&A confirm that large associations, public‑utility associations and foundations are not legally required to use the Standard chart of accounts (Plan comptable normalisé, PCN) or...

Large associations, public‑utility associations and foundations are exempt from the obligation to file the PCN trial balance (balance générale) via the eCDF platform, even though they may still...
Compliance impact
Non‑compliance primarily exposes large associations, public‑utility associations and foundations to deficiencies in statutory annual accounts and registry filings, which can lead to legal and governance risks, increased audit findings and potential supervisory concerns where the CSSF has a stake. For CSSF‑regulated firms, reliance on non‑compliant counterparties may undermine financial reporting integrity and due‑diligence standards, with knock‑on effects in broader regulatory reviews.

Administrative sanction imposed on Transnet Soc Ltd
AI Analysis
The CSSF has published an administrative sanction dated 21 July 2026 in respect of Transnet Soc Ltd, a South African issuer with Luxembourg as home Member State under the Transparency regime. Although the notice itself is very brief, it clearly continues a pattern of enforcement against Transnet for breaches of the Luxembourg Law of 11 January 2008 on transparency requirements for issuers (Transparency Law), including a prior EUR 15,000 fine for late publication of its annual financial report. For compliance teams, this underscores the CSSF’s willingness to publicly sanction and name issuers that fail to meet periodic disclosure obligations, even for relatively modest monetary amounts.
Key dates
31 March 2021 Deadline
– End of the financial year referenced in the prior CSSF sanction against Transnet Soc Ltd for failure to publish its annual financial report within the required time limit
15 November 2021
– CSSF imposed an administrative fine of EUR 15,000 on Transnet Soc Ltd under Article 25(2) of the Transparency Law for late publication of the annual financial report as of 31 March 2021
21 July 2026
– CSSF publishes the administrative sanction “Administrative sanction imposed on Transnet Soc Ltd”; this enforcement notice is made public in line with the Transparency Law’s publication requirements
TBD (within 3 months of CSSF decision)
– Statutory window during which Transnet Soc Ltd (or any sanctioned issuer) may lodge a court action against the CSSF decision with the Luxembourg Administrative Court under Article 27 of the Transparency Law
Suggested considerations
Map all Transparency Law obligations applicable to your entity, including periodic (annual and half‑yearly) reporting and ongoing disclosure of regulated information, and document them in a compliance obligations register.
Review and, where necessary, strengthen internal processes to ensure annual and half‑yearly financial reports are prepared, approved, and published within statutory deadlines for issuers with Luxembourg as home Member State.
Implement a formal disclosure governance framework assigning clear responsibilities to senior management and the board for oversight of regulated information, including escalation procedures where delays or issues arise.
Establish a calendar of regulatory reporting and publication deadlines, including internal cut‑off dates and contingency plans, and ensure it is monitored by compliance and finance functions.
Conduct a gap analysis of prior disclosures (financial reports, major holdings notifications, inside information) to confirm that all items required under the Transparency Law have been published correctly and on time; remediate any deficiencies promptly.

As the 21 July 2026 CSSF notice is an enforcement publication (not a new rule), it does not introduce new regulatory requirements; it applies existing Transparency Law obligations.
Issuers with Luxembourg as home Member State under the Transparency Law must publish annual financial reports within the statutory deadline, typically within four months of financial year-end, and...
Failure to publish periodic financial information within the required time limits can result in administrative fines imposed by the CSSF under Article 25(2) of the Transparency Law.
The CSSF will publicly disclose administrative fines imposed on issuers, including naming the issuer and the amount, in line with Article 26b of the Transparency Law.
Issuers retain the right to challenge CSSF decisions before the Luxembourg Administrative Court within the period set by Article 27 of the Transparency Law (three months from notification), but...
Compliance impact
CSSF administrative fines under the Transparency Law may be modest in absolute value but carry material reputational and supervisory impact because the sanctions, the issuer’s name, and the failures are publicly disclosed. Persistent or repeated non‑compliance with transparency and disclosure obligations can trigger higher fines, closer supervisory scrutiny, and increased legal risk, including potential court actions and investor claims.
Clarifications regarding certain aspects of Regulation (EU) 2019/2088 on sustainability-related disclosures in the financial sector (SFDR)Version 5
AI Analysis
The CSSF’s FAQ clarifies several SFDR disclosure points for Luxembourg fund managers and related entities, especially around Article 8/9 investment strategies, sustainable-investment methodology, and periodic reporting. It also signals supervisory expectations that disclosure changes can be “material” under CSSF circular rules and therefore may trigger formal review and authorisation requirements.
Key dates
02 December 2022
- CSSF published the SFDR FAQ clarifying supervisory expectations for Article 8 and Article 9 disclosures
01 January 2023 Deadline
- UCITS and AIFs disclosing under Article 8 or Article 9 must use the SFDR RTS periodic reporting templates in annual reports issued after this date
Suggested considerations
Review all Article 8 pre-contractual disclosures to confirm that the stated investment strategy clearly explains how the fund’s environmental or social characteristics are achieved.
Strengthen any Article 8 exclusion-based strategy disclosures so they provide sufficient detail for investors to understand the connection between exclusions and the claimed sustainability characteristics.
Reassess all Article 9 product classifications to confirm that the portfolio is built around qualifying sustainable investments, not only exclusions.
Implement controls to verify that Article 9 holdings remain aligned with Article 2(17) SFDR on an ongoing basis throughout the fund lifecycle.
Document and retain the internal methodology used to assess sustainable-investment status, including any thresholds, and ensure it can be provided to investors or supervisors upon request.
What changed
- Article 8 funds must describe how the investment strategy actually enables the fund to meet the environmental and/or social characteristics disclosed to investors.
If an Article 8 fund relies mainly on an exclusion strategy, the CSSF expects the exclusion policy to be detailed enough for investors to understand how the stated characteristics are being met.
Article 9 funds cannot rely only on an exclusion strategy; they must invest in sustainable investments and use a positive selection process that demonstrates alignment with Article 2(17) SFDR.
For Article 9 funds, the CSSF expects sustainable-investment status to be maintained at all times, including on an ongoing basis during the life cycle of the fund.
Financial market participants should make available the methodology used to determine whether an investment is a sustainable investment, including any thresholds used for a pass-fail approach.
Compliance impact
Non-compliance can lead to supervisory scrutiny, requests for remediation, and potential reclassification risk if a product cannot substantiate its Article 8 or Article 9 claims. The practical consequence is heightened greenwashing exposure and the possibility that disclosure changes may need formal review or authorisation before implementation.

The CSSF has republished its MiFID II/MiFIR FAQ (Q&A) in a version dated 13 July 2026, consolidating guidance on investor protection, conduct of business, and reporting obligations applicable to Luxembourg MiFID firms. While the publication page itself is largely technical (cookies, website functioning), firms should treat the 13 July 2026 FAQ version as the current CSSF interpretative benchmark for MiFID II/MiFIR compliance, aligned with ESMA Q&As and recent EU‑level MiFID II/MiFIR review developments.
Key dates
02 March 2026
- Most revised MiFIR transparency requirements under the MiFID II/MiFIR review (amending Delegated Regulation) apply at EU level, influencing the content and focus of national FAQs and supervisory guidance, including CSSF’s
13 July 2026 Deadline
- CSSF publishes/updates the MiFID II/MiFIR FAQ version dated 13 July 2026, which becomes the current reference point for CSSF supervisory expectations on MiFID II/MiFIR compliance
Suggested considerations
Review the latest CSSF MiFID II/MiFIR FAQ (13 July 2026 version) in full, comparing it against existing internal MiFID II/MiFIR policies, procedures, and controls to identify gaps or misalignments.
Confirm and, where necessary, update client‑facing disclosures to clearly state whether investment services (especially advice and portfolio management) are provided on an independent or non‑independent basis, and ensure that inducement arrangements are consistent with this classification.
Reassess inducement frameworks (commissions, fees, non‑monetary benefits) for investment advice and portfolio management to ensure that no prohibited inducements are received or retained where services are independent or involve portfolio management.
Review and update product governance frameworks, including target market definition processes and product approval procedures, to ensure that each instrument’s intended target market is properly documented and consistently used by distributors.
Examine best execution policies to confirm they are clear, detailed, and understandable to clients, and implement or enhance ongoing monitoring mechanisms (e.g. execution quality reports, periodic reviews) to evidence compliance with best execution obligations.
What changed
Because the visible page content provided is limited to technical and cookie‑related information, the key points below focus on the regulatory substance of the CSSF MiFID II/MiFIR FAQ (Q&A) as the...
The CSSF confirms the application of MiFID II investor protection rules to Luxembourg investment service providers, including obligations on inducements, suitability, product governance, and best...
The FAQ reiterates that investment services providers must inform clients clearly whether their investment advice or services are provided on an independent or non‑independent basis, and explains the...
The FAQ clarifies that inducements are expressly prohibited when investment advice is provided on an independent basis and for portfolio management services, requiring firms to structure their...
The CSSF guidance reflects product governance obligations: manufacturers must define a target market for each financial instrument based on clients’ knowledge and experience, financial situation,...
Compliance impact
Non‑compliance with CSSF’s MiFID II/MiFIR expectations can lead to supervisory findings, remediation orders, administrative sanctions, and potential reputational damage, particularly where investor protection (suitability, inducements, best execution) is compromised. Given the 2026 EU‑level MiFID II/MiFIR review changes and the updated FAQ, firms that fail to update frameworks risk being assessed against a higher and more current supervisory benchmark.

ESMA has launched a public consultation (via CSSF notification) on its technical advice to the European Commission for simplifying the EU Taxonomy disclosure framework, focusing on selected KPIs under the Taxonomy Disclosures Delegated Act and reducing reporting burdens. This matters for compliance teams because it is the first formal step in the review of Article 8 Taxonomy disclosure KPIs that will likely change how financial and non‑financial undertakings calculate and disclose Taxonomy‑related indicators from around Q3 2027.
Key dates
01 July 2026
- ESMA launches its public consultation on simplifying the EU Taxonomy disclosure framework and technical advice on selected KPIs under the Taxonomy Disclosures Delegated Act
22 July 2026
- ESMA holds a public hearing to present its proposals and engage with stakeholders on the consultation
12 August 2026 Deadline
- Deadline for stakeholders to submit responses to ESMA’s consultation on Taxonomy disclosure simplification
By October 2026
- ESMA (and other ESAs) are expected to deliver final technical advice on the Taxonomy Disclosures Delegated Act KPIs to the European Commission
Q1 2027
- Target date for the European Commission to complete its review of the Taxonomy Disclosures Delegated Act based on ESAs’ advice
Suggested considerations
Conduct an internal impact assessment of current Taxonomy Article 8 KPI calculation and reporting processes, focusing on OpEx, Commissions and Fees, Trading Book, and Underwriting KPIs, to identify pain points and simplification priorities.
Prepare and submit a response to ESMA’s consultation by 12 August 2026, either directly or via industry associations, articulating specific operational, data, and system challenges and concrete proposals for simplification.
Register for and attend ESMA’s public hearing on 22 July 2026 to understand the detailed proposals, ask clarifying questions, and align internal positions ahead of submission.
Coordinate with regulatory affairs, sustainability, risk, and finance functions to develop a unified institutional position on the desired design of revised KPIs and group‑level reporting under the Taxonomy Disclosures Delegated Act.
Map dependencies between Taxonomy Article 8 data and other ESG reporting (including SFDR product disclosures and CSRD/ESRS reporting) to anticipate how changes to KPIs may affect cross‑framework consistency and data architecture.
What changed
- ESMA is consulting on technical advice to the European Commission specifically targeting selected KPIs under the Taxonomy Disclosures Delegated Act (Article 8 of the Taxonomy Regulation), including...
The stated policy objective is simplification of the EU Taxonomy disclosure framework while preserving decision‑useful information for investors and supervisors.
ESMA aims to reduce reporting burdens for market participants, notably corporates and financial institutions subject to Taxonomy Article 8 disclosures.
The consultation covers selected KPIs under the Taxonomy Disclosures Delegated Act, with the European Commission having requested focused advice on: OpEx KPI of non‑financial firms; Commissions and...
ESMA is proposing more pragmatic approaches to group‑level reporting for mixed groups, including reporting at parent‑undertaking level to reduce complexity for conglomerates.
Compliance impact
In the short term, non‑participation in the consultation does not create direct non‑compliance risk but may leave firms exposed to a revised framework that does not reflect their operational realities. In the medium term (Q3 2027 onward), failure to implement the revised Taxonomy KPIs and disclosure rules will create material regulatory, supervisory, and reputational risk, given the central role of Taxonomy data in EU sustainable finance and investor disclosures.

- CSSF’s supervisory disclosure covers **measures and administrative penalties for the year 2025**
23 July 2025
- CSSF published the prior year’s supervisory disclosure page referencing the **2024** measures and penalties, showing the annual disclosure cycle
28 July 2025 Deadline
- CSSF issued an **administrative sanction** in an AML/CFT case, imposing a reprimand for non-compliance with the AML/CFT Law
Suggested considerations
Review the firm’s AML/CFT control framework against the Luxembourg AML/CFT Law provisions that can trigger CSSF reprimands or sanctions, including governance, monitoring, and escalation controls.
Verify that suspicious activity detection, investigation, and escalation procedures are documented, implemented, and tested for effectiveness.
Reassess whether internal controls are sufficient to demonstrate timely compliance with professional AML/CFT obligations under CSSF supervision.
Update remediation tracking to ensure supervisory findings are closed out promptly and supported by evidence of corrective action.
Brief senior management on the reputational impact of public supervisory disclosures and ensure that recurring weaknesses are escalated to the board.
What changed
- CSSF has published its 2025 supervisory disclosure covering supervisory measures and administrative penalties taken during the year.
The publication serves as a public register-style disclosure of enforcement outcomes, increasing transparency around CSSF supervision and sanctioning activity.
A related 2025 CSSF administrative sanction shows that AML/CFT non-compliance can result in a reprimand under the amended Luxembourg AML/CFT Law.
The 28 July 2025 sanction confirms that CSSF can act where firms fail to maintain adequate professional AML/CFT obligations and related internal controls.
Compliance impact
The compliance impact is material because CSSF enforcement disclosures can expose weaknesses to the market, counterparties, auditors, and other regulators, creating reputational and supervisory pressure. Non-compliance with AML/CFT obligations can lead to public reprimands and potentially more severe measures if deficiencies persist or are systemic.

1) high-risk jurisdictions on which enhanced due diligence and, where appropriate, counter-measures are imposed2) jurisdictions under increased monitoring of the FATFVersion of 19 June 2026
AI Analysis
CSSF published a new **Annex to Circular CSSF 22/822** on **22 June 2026**, updating the Luxembourg regulator’s reference list of FATF **high-risk jurisdictions** and **jurisdictions under increased monitoring**. For compliance teams, this matters because AML/CFT country-risk scoring, enhanced due diligence triggers, and sanctions-style controls must be aligned to the current FATF position reflected by CSSF.
Key dates
27 October 2022
- Circular CSSF 22/822 was issued, establishing the framework for using FATF statements on high-risk jurisdictions and jurisdictions under increased monitoring
19 June 2026
- The annex was updated to this version date, reflecting the current FATF jurisdiction lists and associated risk posture
22 June 2026
- CSSF published the annex on its website, making the updated reference document operationally relevant for supervised firms
Suggested considerations
Review your AML/CFT country-risk methodology and update it to reflect the 19 June 2026 FATF/CSSF jurisdiction list.
Re-screen customers, beneficial owners, counterparties, and transactions against the updated high-risk and monitored jurisdiction lists.
Apply enhanced due diligence for relationships and transactions involving high-risk jurisdictions, and escalate where counter-measures may be required.
Reassess risk ratings for customers linked to jurisdictions under increased monitoring and document the rationale for any continued onboarding, retention, or exit decisions.
Update automated screening rules, transaction-monitoring scenarios, and onboarding checklists so they use the current CSSF annex version.
What changed
- CSSF republished the annex to Circular CSSF 22/822 in a Version of 19 June 2026, meaning firms should treat this as the current Luxembourg reference point for FATF jurisdiction screening and...
The annex distinguishes between high-risk jurisdictions subject to enhanced due diligence and, where appropriate, counter-measures, and jurisdictions under increased monitoring that require...
The publication incorporates the FATF’s current statements on jurisdictions with strategic AML/CFT/CPF deficiencies, which is the basis for operational country-risk controls used by...
The related Circular CSSF 22/822 remains the framework document that instructs professionals to use FATF statements when assessing jurisdictional ML/TF/PF risk.
Compliance impact
Non-compliance can lead to supervisory findings, remediation orders, and possible enforcement action where firms fail to apply risk-sensitive AML controls consistent with CSSF/FATF expectations. The practical impact is highest for onboarding, correspondent-like relationships, cross-border payments, and any business line exposed to higher-risk jurisdictions.
This is a notification form from CSSF regarding a Luxembourg-based Investment Fund Manager (IFM) seeking to provide ancillary services to third parties.

CSSF communication announcing new notification procedures for Luxembourg-based investment fund managers seeking to provide ancillary services to third parties under transposed EU Directive 2024/927. Informational guidance on regulatory requirements and form submission process.
The CSSF has introduced two **mandatory standardised application forms** for authorisation of UCITS **domestic mergers** under the Luxembourg Law of 17 December 2010 and **outbound cross‑border mergers** where the receiving UCITS is located in another EU Member State under Directive 2009/65/EC. From 19 June 2026, any new UCITS merger authorisation request of these types must use the new forms and be filed by email with the full supporting documentation required by the applicable UCITS merger provisions.
Key dates
19 June 2026
- CSSF communiqué published announcing the two new merger authorisation forms for UCITS domestic mergers and UCITS outbound cross‑border mergers
19 June 2026 Deadline
- **Start of mandatory use of the new forms** for all **new merger authorisation applications** filed with the CSSF; applications submitted from this date must use the new templates and be sent to [email protected]
Suggested considerations
Identify all current and planned UCITS domestic and outbound cross‑border merger projects and determine which will have CSSF authorisation requests submitted on or after 19 June 2026 so that the new forms are used.
Download and review in detail the “Application form for authorisation of a UCITS domestic merger” and “Application form for authorisation of a UCITS outbound cross‑border merger” and map each field of the forms to existing internal data sources and documents.
Update internal UCITS merger procedures and checklists to replace any existing CSSF filing templates with the new standardised forms and to include the requirement that all merger authorisation applications are submitted to [email protected].
Train legal, product, operations and compliance staff involved in UCITS mergers on how to complete the new forms accurately, including coordination of information across the prospectus, KIIDs/KIDs, common draft merger terms, depositary statements and shareholder communications.
Review and, where necessary, update board and governance templates (board minutes, resolutions approving merger terms) to ensure they produce all information that the new forms require to be confirmed or attached.
What changed
- The CSSF has created a standardised “Application form for authorisation of a UCITS domestic merger” specifically for merger authorisation requests where both merging and receiving UCITS are...
The CSSF has created a standardised “Application form for authorisation of a UCITS outbound cross‑border merger” for mergers where the merging UCITS is Luxembourg‑authorised and the receiving UCITS...
Use of the two new forms is mandatory for all new merger authorisation applications submitted to the CSSF from 19 June 2026 onwards; legacy formats (ad‑hoc letters or bespoke templates) may no longer...
Each application form must be “duly completed” and accompanied by all documents required under the applicable UCITS merger regulations, including the common draft terms of merger, updated prospectus...
The CSSF has specified a centralised submission channel for these applications: completed forms and supporting documentation must be sent to [email protected], aligning merger filings with the...
Compliance impact
Non‑compliance (e.g. using outdated templates or submitting incomplete forms) is likely to result in the CSSF treating the file as inadmissible or incomplete, delaying merger authorisation and potentially requiring postponement of planned merger effective dates. Repeated deficiencies or failure to comply with the standardised process may also raise supervisory concerns about the firm’s governance and regulatory controls around UCITS product actions.
This is an informational regulatory document from CSSF regarding application procedures for UCITS outbound cross-border mergers. It pertains to investment management authorization processes and is primarily procedural/administrative in nature rather than substantive regulatory change, warranting null urgency...

The CSSF is flagging to the market a new **CNC Q&A 26/037** that clarifies the distinction between **statutory (legal) annual accounts** and **annual accounts prepared for contractual or voluntary purposes**, and an interview indicating an upcoming **overhaul of Luxembourg accounting legislation**. This matters for compliance and finance teams because mislabeling or misusing “statutory” accounts, or applying CNC doctrine inconsistently, can create legal, regulatory, lending, and investor‑information risks, and the announced legislative reform implies future adjustments to accounting policies, reporting processes, and governance.
Key dates
08 June 2026
– Publication of the interview with the CNC chairman in Paperjam announcing that Luxembourg accounting legislation will be overhauled
15 June 2026
– CSSF press release published, drawing attention to CNC Q&A 26/037 and the CNC chairman’s interview and signaling supervisory expectations that entities consider this doctrine when preparing annual accounts
Suggested considerations
Obtain and review the full CNC Q&A 26/037 and the CNC chairman’s interview (French‑language originals), ensuring that finance, accounting, and compliance teams understand the clarified distinctions between statutory and contractual/voluntary annual accounts.
Map all sets of financial statements prepared by each Luxembourg entity (statutory accounts, covenant‑based or lender‑specific accounts, group reporting packages, management accounts, etc.) and classify each set as statutory or contractual/voluntary in line with CNC Q&A 26/037 definitions.
Update internal accounting policies and manuals to explicitly define statutory versus contractual/voluntary annual accounts, specify the applicable accounting principles and disclosures for each, and describe any differences in measurement, presentation, or scope.
Assess current practices for communicating financial information to lenders, investors, regulators, and other stakeholders to confirm that non‑statutory accounts are not labeled or presented in a way that could be misinterpreted as statutory accounts approved under Luxembourg company law.
Implement clear labeling and disclosure conventions on the face of financial statements and in accompanying notes (e.g., in engagement reports, board minutes, and management communications) to distinguish statutory annual accounts from any contractual or voluntary accounts.

Compliance impact
Failure to correctly distinguish and label statutory versus contractual/voluntary annual accounts can lead to breaches of Luxembourg company law, mis‑disclosure to investors, lenders, and regulators, and increased enforcement risk from the CSSF and other authorities. Misalignment between CNC doctrine and practice may also complicate audits and regulatory reviews, leading to qualified opinions, remediation requirements, or sanctions in severe cases.
Q&A CNC 26/037 titled “A reminder of the differences between annual accounts prepared for statutory purposes and annual accounts prepared for contractual purposes or on a voluntary basis” and interview with the chairman of the CNC (Mr. Yvan Thommes)
AI Analysis
The CSSF is formally directing market participants’ attention to new guidance from the Luxembourg Commission des normes comptables (CNC) clarifying the distinction between **statutory annual accounts** and **contractual/voluntary annual accounts**, and to an interview announcing a forthcoming overhaul of Luxembourg accounting law. This matters for compliance and finance functions because it affects how firms label, prepare, approve, file and use financial statements in regulatory, contractual and investor contexts, and foreshadows medium‑term changes to the Luxembourg accounting framework.
Key dates
08 June 2026
– Publication of the interview with the CNC chairman in Paperjam announcing that Luxembourg accounting legislation will be subject to a comprehensive overhaul
15 June 2026
– CSSF communiqué published, formally drawing attention to CNC Q&A 26/037 and the CNC chairman’s interview, and thereby activating supervisory expectations that firms take these clarifications into account
TBD (post‑2026)
– Effective dates for the planned overhaul of Luxembourg accounting legislation remain to be defined; firms should anticipate consultation and transition periods once draft law is published
Suggested considerations
Identify all sets of financial statements prepared by the firm or its Luxembourg entities (statutory, covenant/banking, shareholder/management, group‑reporting, voluntary) and map which are statutory annual accounts under Luxembourg law and which are contractual or voluntary.
Review the CNC Q&A 26/037 in detail and update internal accounting manuals and group reporting policies to embed the CNC’s definitions, terminology and criteria for statutory versus non‑statutory annual accounts.
Implement a clear labelling and disclosure convention so that all non‑statutory financial statements explicitly state their nature (contractual or voluntary) and are not presented or communicated as statutory annual accounts.
Update templates for board and shareholder approvals, minutes and resolutions to ensure that the correct set of statutory annual accounts is approved for legal purposes such as profit appropriation, dividend distribution, capital reduction and regulatory filings.
Review all contractual arrangements (loan agreements, bond indentures, shareholder agreements, management incentive plans and service contracts) to determine whether they require statutory annual accounts or allow contractual/adjusted accounts, and align documentation and practice accordingly.
What changed

Misclassification or misuse of contractual/voluntary accounts where statutory annual accounts are legally required can lead to breaches of Luxembourg company law, invalid shareholder resolutions, misstatements in regulatory or investor reporting, and potential CSSF supervisory findings. Consistent application of the CNC guidance will be expected in future inspections and could influence audit opinions and governance assessments.

Administrative sanction imposed on Stonehage Fleming Luxembourg S.A.
AI Analysis
The CSSF has announced that an **administrative sanction was imposed on Stonehage Fleming Luxembourg S.A. on 5 March 2026**, but it has not yet published the underlying decision or grounds. For compliance teams, this signals that the CSSF continues to actively use sanctions against Luxembourg wealth/asset management entities and that a detailed decision is likely forthcoming, which may contain important precedents on governance, AML/CFT or conduct requirements.
Key dates
05 March 2026
- CSSF imposes the administrative sanction on Stonehage Fleming Luxembourg S.A. (date of decision)
09 June 2026
- CSSF publicly announces the administrative sanction and the existence of a PDF decision (date of publication on CSSF website)
Suggested considerations
Monitor the CSSF website for publication of the detailed PDF decision relating to the administrative sanction of 5 March 2026 against Stonehage Fleming Luxembourg S.A.
Once available, review the full decision to identify the specific legal bases (e.g. LFS, Law of 2010, Law of 2013, AML/CFT Law) and control failures cited by the CSSF.
Map the identified weaknesses from the decision against your firm’s governance, internal control, delegate oversight and AML/CFT frameworks to identify any similar risk areas.
Update internal compliance risk assessments to reflect the enforcement themes highlighted in this and recent CSSF sanctions, including the weighting of enforcement risk for organisational and AML/CFT deficiencies.
Review and, where necessary, strengthen board and senior management oversight arrangements, including the documentation of decisions, challenge and escalation processes, in anticipation of CSSF expectations evidenced in the forthcoming decision.
What changed
At this stage, based on the CSSF notice alone, no new legal or regulatory requirements are introduced; the publication is a transparency notice that a sanction decision exists.
the Law of 5 April 1993 on the financial sector (LFS), the Law of 17 December 2010 on undertakings for collective investment, the Law of 12 July 2013 on AIFMs, and the Law of 12 November 2004 on the...

the factual deficiencies identified (e.g., weaknesses in governance, delegate oversight, AML risk assessment, customer due diligence), and
Compliance impact
The specific financial and qualitative impact of this particular sanction is not yet public, but recent CSSF cases show that deficiencies in governance, delegate oversight and AML/CFT controls can lead to significant fines, public censure and supervisory follow-up. Non-compliance increases the likelihood of intrusive inspections, remediation programmes under CSSF scrutiny, and reputational risk with clients and counterparties.
This is an updated regulatory guidance document from CSSF regarding marketing of non-EU Alternative Investment Funds (AIFs) by EU-based AIFMs to professional investors in Luxembourg.
This is an updated regulatory form and guidance from CSSF regarding marketing of AIFs by non-EU AIFMs to professional investors in Luxembourg under Article 45 of the AIFM Law. It is informational content providing procedural requirements for asset managers seeking to market alternative investment funds.
The CSSF has launched a consultation on national **Guidance on Money Market Fund Weekly Liquid Asset (WLA) Levels**, aligned with the European Commission’s 2026 MMF report, which defines “market resilience” WLA benchmarks above the MMFR regulatory minimums. This signals a move toward **enhanced liquidity risk management and intensified supervisory scrutiny** for Luxembourg‑authorised MMFs whose WLA levels fall below these resilience benchmarks, even if they remain above the legal minimum.
Key dates
11 May 2026
– European Commission publishes its report on the adequacy of the MMFR and FAQs, identifying market resilience WLA levels for VNAV and CNAV/LVNAV MMFs
15 May 2026
– CSSF informs the market of the Commission’s MMF report and FAQs and flags the identified WLA “market resilience” benchmarks
8 June 2026
– CSSF publishes the communiqué launching the consultation on “Guidance on Money Market Fund Weekly Liquid Asset Levels.”
3 August 2026 Deadline
– Deadline for stakeholders to submit electronic responses on the consultation to the CSSF at [email protected]
Suggested considerations
Review the CSSF consultation paper “Guidance on Money Market Fund Weekly Liquid Asset Levels” in detail and map the proposed WLA resilience benchmarks against existing MMF liquidity policies, procedures and internal limits.
Perform a quantitative impact analysis comparing each MMF’s historical and current WLA levels against both MMFR minimum requirements and the Commission’s market resilience benchmarks (20% for VNAV; 40% for LVNAV and CNAV) to identify potential shortfalls or pressure points.
Assess and, where necessary, update MMF liquidity risk management frameworks to incorporate explicit internal WLA targets, triggers and escalation procedures linked to the new resilience benchmarks, including governance oversight and board reporting.
Integrate the proposed WLA resilience levels into stress testing programmes under Article 28 MMFR, ensuring scenarios reflect the ability of funds to maintain or restore WLA around the benchmark levels under severe but plausible market stress.
Revisit know‑your‑investor / liability profile analysis under Article 27 MMFR to ensure that internal WLA targets adequately reflect investor concentration, redemption behaviour, dealing frequency and distribution channels.
What changed
- The CSSF, in coordination with the European Commission, AMF (France) and Central Bank of Ireland, is consulting on national guidance that operationalises the Commission’s “market resilience” levels...
The guidance will introduce non-binding but supervisory‑relevant WLA benchmarks designed to indicate when an MMF’s liquidity profile may warrant closer scrutiny and additional supervisory engagement.
The consultation builds on the European Commission’s 11 May 2026 report, which identifies WLA benchmarks of 20% for VNAV MMFs and 40% for LVNAV and CNAV MMFs, compared with the MMFR regulatory minima...
The guidance is intended to support more consistent and well‑calibrated supervision of MMFs across the EU, specifically on liquidity resilience under stress.
MMFs that fall below the identified “market resilience” WLA levels, even while remaining compliant with the MMFR minimum percentages, can expect increased supervisory scrutiny, closer monitoring and...
Compliance impact
The immediate legal impact is limited because the text is a consultation on guidance, not a binding rule change, but the direction of travel is towards higher de‑facto liquidity expectations and more intrusive supervision where WLA levels fall below resilience benchmarks. Non‑alignment with the eventual guidance is likely to result in increased supervisory challenge, potential remediation demands and heightened risk that liquidity weaknesses are escalated within the CSSF’s prudential risk framework.
The CSSF has launched a consultation on new **Guidance on Money Market Fund (MMF) Weekly Liquid Asset Levels**, signalling its intention to clarify supervisory expectations on the calibration and use of weekly liquid asset (WLA) buffers under the EU Money Market Funds Regulation (MMFR). This matters for compliance teams because it will likely drive changes to MMF liquidity risk frameworks, escalation triggers, governance around liquidity thresholds, and potentially the design of internal stress tests and contingency plans. ---
Key dates
TBD (final guidance – est. late 2026)
– Expected date for CSSF to publish final guidance on MMF weekly liquid asset levels, following review of consultation feedback
08 June 2026
– CSSF publishes consultation communiqué “Guidance on Money Market Fund Weekly Liquid Asset Levels” and opens consultation on its proposed guidance
– Expected closing date for industry comments on the consultation (to be confirmed once the full consultation paper and response deadline are made available by CSSF)
Suggested considerations
Review the CSSF consultation paper in full as soon as it is available and identify all proposed expectations relating to weekly liquid asset levels, monitoring, and escalation.
Map the proposed CSSF guidance against current MMF liquidity policies, prospectus disclosures, and internal procedures to identify gaps and potential areas needing enhancement.
Assess whether existing MMF weekly liquidity monitoring tools, dashboards, and reporting are sufficient to meet anticipated CSSF expectations on frequency, granularity, and early warning indicators.
Evaluate the current escalation framework for declining WLA levels, including board and senior management involvement, and update governance documentation to align with the likely CSSF approach to thresholds and decision‑making.
Review MMF stress‑testing methodologies to ensure that scenarios adequately capture severe but plausible redemption and market stress in relation to WLA levels and that results are integrated into risk appetite and contingency planning.
What changed
Given the consultation nature and the absence of a published consultation text in the extract, the following points reflect what compliance teams should reasonably anticipate and prepare for, based...
The CSSF is consulting on formal guidance that will specify how MMFs domiciled in Luxembourg should determine, monitor, and maintain weekly liquid asset levels under the EU Money Market Funds...
The guidance is expected to operationalise the MMFR WLA requirements (for example, minimum weekly liquidity levels and interaction with redemption activity) by setting out supervisory expectations on...
The consultation will likely address the interaction between WLA levels and the use of liquidity management tools (such as gates, fees, or suspensions), including expectations on when and how...
The CSSF is expected to clarify how MMFs should incorporate WLA targets and thresholds into their internal risk management policies, including stress-testing assumptions, early warning indicators,...
Compliance impact
Non‑compliance with the forthcoming CSSF guidance, once finalised, could result in supervisory findings, remediation programmes, and potential restrictions on MMF activities, particularly in stressed markets where liquidity management failures are highly scrutinised. Given MMFs’ systemic importance, firms should treat this as a high‑impact development for liquidity risk management, board oversight, and investor protection.
Administrative sanction imposed on a registered alternative investment fund manager
AI Analysis
The CSSF has published an administrative sanction dated 17 April 2026 imposed on a **registered alternative investment fund manager (registered AIFM)**, but the public notice contains no detail on the nature of the breach, legal basis, or penalty level, which are presumably only available in the linked PDFs. For compliance teams, this is another data point that the CSSF is actively enforcing the AIFMD and related Luxembourg implementing laws against even registered (sub‑threshold) AIFMs, not only fully authorised managers. Because the body text and PDFs are not accessible from the prompt, the analysis below focuses on the **regulatory framework and typical CSSF enforcement themes** that are most likely relevant, and how compliance teams at AIFMs should respond. ---
Key dates
17 April 2026
- CSSF adopts an administrative sanction decision against a registered alternative investment fund manager
05 June 2026
- CSSF publishes the administrative sanction notice on its website, including links to the detailed sanction decision in PDF form
Suggested considerations
Obtain and review the full CSSF sanction decision PDFs published with the 17 April 2026 administrative sanction to identify the specific legal provisions, facts and control failures cited.
Map the identified breaches (e.g. governance, risk management, reporting, valuation, delegation, marketing, or conduct of business) against your firm’s current policies and procedures under the Law of 12 July 2013 on AIFMs and the AIFMD framework.
Perform a targeted gap analysis for registered AIFMs, focusing on whether “light” registration has led to under‑resourced compliance, risk, valuation, or reporting functions that could attract similar enforcement.
Review and, where necessary, update internal governance arrangements, including board oversight, documented decision‑making, and escalation processes for regulatory issues, to align with CSSF expectations evidenced in recent sanctions against AIFMs and management companies.
Test the effectiveness of regulatory reporting and disclosure processes (including Annex IV reporting, investor disclosures, periodic reporting, and prospectus/issuing document accuracy) to ensure they are complete, timely and consistent with CSSF rules.
What changed
There are no formal rule changes announced in the short notice itself; however, the enforcement action reinforces several practical expectations that compliance teams should treat as de‑facto...
CSSF confirms that registered alternative investment fund managers are fully subject to Luxembourg’s AIFM framework, including the Law of 12 July 2013 on alternative investment fund managers and the...
CSSF reiterates, through enforcement practice, that registration status (sub‑threshold AIFM) does not shield managers from administrative sanctions where organisational, conduct, reporting, or...
CSSF continues its policy of public naming and shaming through publication of administrative sanctions, signalling that reputational impact is a key component of its deterrence strategy.
The sanction underscores the CSSF’s readiness to use its full sanctioning toolkit under the AIFM Law, which can include monetary fines, public statements, and prohibitions or restrictions on...
Compliance impact
The compliance impact is medium to high: while the publication does not create new rules, it underscores that the CSSF will actively sanction even registered AIFMs and publicly disclose those sanctions, increasing both regulatory and reputational risk for weakly controlled managers. Firms that treat registration as a “lighter” supervisory regime without proportionate controls are particularly exposed to similar action.
CSSF warning against unauthorized entity claiming to offer investment services without Luxembourg authorization. High urgency due to active illicit operations and consumer protection risk, though not critical as it is a warning notice rather than emergency alert.

This is a regulatory statistical report from CSSF on collective investment undertakings (UCIs) in Luxembourg as of April 2026. It provides market data, net asset developments, and registration/deregistration information.
The CSSF has published a Feedback Report following a thematic review of the **valuation framework for less liquid and illiquid assets**, focused primarily on Luxembourg AIFMs managing AIFs in asset classes such as private equity, real estate, infrastructure, private debt and fund of funds, and on UCITS “trash ratio” positions under Article 41(2) of the UCI Law. All Luxembourg IFMs are explicitly expected to benchmark their existing valuation frameworks against the CSSF’s observations and recommendations and to implement corrective measures, with valuation risk confirmed as a key supervisory priority for 2026.
Key dates
End 2023
– CSSF thematic review launched by dedicated questionnaire to IFMs, with work conducted through 2024 and 2025 (contextual start of the current thematic exercise)
Throughout 2024 and 2025
– CSSF conducts off‑site and on‑site work as part of the dedicated thematic review on valuation frameworks for less liquid and illiquid assets
2026 Deadline
– Valuation risk for less liquid and illiquid assets is confirmed as a key supervisory priority, implying heightened supervisory focus and potential follow‑up actions during the year; no hard implementation deadline is set but prompt action is implicitly expected
04 June 2026
– CSSF publishes the Communication and Feedback Report on the thematic review and formally expects IFMs to perform a benchmarking exercise and implement corrective measures as needed
Suggested considerations
Perform a structured benchmarking of existing valuation policies, procedures, methodologies and controls against the detailed observations and recommendations in the CSSF Feedback Report on valuation frameworks for less liquid and illiquid assets.
Document, at IFM and fund level, all identified gaps or weaknesses in the current valuation framework, including for AIFs in illiquid strategies and UCITS Article 41(2) trash ratio positions.
Develop and approve a remediation plan with clear owners, milestones and target dates to address identified shortcomings in valuation governance, methodologies, model validation, data sources and control processes.
Review and, where necessary, update valuation policies and procedures to ensure they explicitly cover less liquid and illiquid assets, stressed market conditions, use of external valuers, and documentation standards across the investment lifecycle.
Enhance valuation governance by clearly defining roles and responsibilities (including segregation from portfolio management where applicable), escalation procedures, and oversight by the board/senior management.
What changed
- The CSSF publishes a dedicated Feedback Report on the thematic review of valuation frameworks for less liquid and illiquid assets and formally expects IFMs to use it as guidance for implementing...
All Luxembourg IFMs are required to conduct a benchmarking exercise of their valuation frameworks against the CSSF’s observations and recommendations set out in the new Feedback Report.
Where gaps or weaknesses are identified through this benchmarking, IFMs are expected to implement corrective measures to strengthen their valuation policies, procedures and lifecycle controls for...
The thematic review scope formally covers AIFMs of AIFs investing in less liquid and illiquid assets (including private equity, real estate, infrastructure, private debt and fund of funds), and, on...
The CSSF explicitly links this thematic work to previous supervisory exercises (ESMA CSA on valuation, CSSF self‑assessment questionnaires, and on‑site inspection feedback) and consolidates...
Compliance impact
Failure to benchmark and remediate valuation frameworks for less liquid and illiquid assets exposes IFMs to material supervisory risk, including targeted reviews, formal remedial orders or sanctions, particularly given the CSSF’s designation of valuation risk as a key supervisory priority in 2026. Deficient valuation practices also heighten the risk of NAV errors, investor detriment and potential civil liability or reputational damage.
CSSF warning against unauthorized entity claiming to provide investment services without Luxembourg authorization. High urgency due to active illicit operations and consumer protection risk. Entity operating across multiple financial service categories without proper licensing.
The CSSF has issued a feedback report on a thematic review of the **valuation framework for less liquid and illiquid assets**, signalling intensified supervisory focus on how Luxembourg investment fund managers value complex, hard‑to‑price positions. This matters because it will drive stricter expectations around valuation governance, model oversight, data validation, and the interaction between valuation, liquidity management, and investor protection for funds holding such assets. Although the specific 2026 feedback report text is not yet available, it clearly follows and deepens the CSSF’s 2023 Feedback Report on ESMA’s CSA on Valuation and its 2026 supervisory priorities on valuation, with a narrower focus on less liquid and illiquid assets.
Key dates
18 July 2023
– CSSF publishes its Feedback Report on the ESMA Common Supervisory Action (CSA) on Valuation, setting out broad expectations for valuation frameworks, including for less liquid assets
31 December 2023 Deadline
– Deadline by which all IFMs managing UCITS and/or AIFs were required to complete a comprehensive assessment of their valuation frameworks and implement necessary corrective measures in line with the 2023 CSSF Feedback Report on valuation
Early 2026
– CSSF identifies valuation as an ongoing key supervisory priority for the investment fund sector in its 2026 priorities, with specific focus on IFM valuation organisation and processes
04 June 2026
– CSSF publishes the new Feedback Report on the thematic review of valuation frameworks for less liquid and illiquid assets, signalling renewed and more granular supervisory scrutiny of this area
TBD (2026–2027)
– CSSF is expected to conduct follow‑up supervisory work (off‑site reviews and on‑site inspections) to test implementation of its expectations on valuation of less liquid and illiquid assets; firms should plan remediation programmes within months rather than years
Suggested considerations
Conduct a comprehensive gap analysis of existing valuation policies and procedures against the CSSF’s feedback on valuation, with specific attention to less liquid and illiquid assets, and document all identified weaknesses and remediation actions.
Update and formally approve valuation policies and procedures to clearly define methodologies, model hierarchies, and data source selection for less liquid and illiquid assets, including explicit provisions for stressed market conditions.
Implement or enhance a formal valuation model governance framework for illiquid asset models, including independent model validation, periodic back‑testing, documentation of assumptions, and at least annual model reviews.
Review and, where necessary, redesign organisational arrangements to ensure the operational and hierarchical independence of the valuation function from portfolio management, and adjust remuneration policies to avoid performance‑linked incentives for valuation staff.
Strengthen controls over external pricing providers and external valuers by documenting selection criteria, performing initial and ongoing due diligence, challenging methodologies, and periodically back‑testing third‑party valuations of illiquid assets.
What changed
Based on the prior CSSF feedback on valuation and the indicated thematic focus, compliance teams should expect the following concrete expectations to apply specifically to less liquid and illiquid...
Investment fund managers must maintain concise, centralised, and comprehensive valuation policies and procedures that explicitly cover all asset types, including less liquid and illiquid instruments,...
Valuation policies must define and justify the valuation methodologies and models used for less liquid and illiquid assets, including the hierarchy of methods, model selection criteria, and...
Firms must perform robust model governance for valuation models used on less liquid and illiquid assets, including independent model review (by staff not involved in model development), back‑testing,...
Valuation frameworks must explicitly address stressed market conditions for illiquid and thinly traded assets, including triggers for stress conditions, alternative valuation methodologies under...
Compliance impact
Non‑compliance exposes firms to heightened risk of CSSF supervisory measures, including remediation orders, restrictions on activities, and possible enforcement actions, especially where valuation weaknesses have led or could lead to investor detriment. Given the CSSF’s explicit supervisory priority on valuation, firms with significant illiquid exposures should treat this as a high‑impact issue requiring proactive remediation and robust documentation.
amending the regulatory technical standards laid down in Delegated Regulation (EU) 2019/979 as regards updating the list of data necessary for the classification of prospectuses and the list of information that can be incorporated by reference into prospectuses
AI Analysis
Commission Delegated Regulation (EU) 2026/395 of 23 February 2026 amends the Prospectus Regulation RTS in Delegated Regulation (EU) 2019/979 to update: (i) the **data set used for ESMA classification and filing of prospectuses** and (ii) the **categories of information that may be incorporated by reference** into a prospectus. For compliance teams in Luxembourg and across the EU, this means prospectus production, filing templates, and reference documentation frameworks must be revised so that all new prospectuses and supplements meet the updated RTS data and incorporation-by-reference standards under Regulation (EU) 2017/1129.
Key dates
14 March 2019
- Original Delegated Regulation (EU) 2019/979 is adopted, setting the RTS on key financial information, publication and classification of prospectuses, advertisements, supplements and incorporation by reference
23 February 2026
- Commission Delegated Regulation (EU) 2026/395 is adopted, amending Delegated Regulation (EU) 2019/979 on the list of data necessary for prospectus classification and the list of information allowed to be incorporated by reference
2 June 2026
- CSSF publishes notice of Delegated Regulation (EU) 2026/395, signalling its relevance for Luxembourg‑supervised entities and prospectus approval processes
TBD (upon OJ publication)
- The Delegated Regulation will enter into force on the date specified in the Official Journal; in line with standard EU practice, firms should expect application from a specified date shortly after OJ publication and plan prospectus updates accordingly
Suggested considerations
Map all existing prospectus templates, checklists and workflows against the revised Delegated Regulation (EU) 2019/979 data fields and immediately identify gaps in prospectus classification data and reference documentation.
Update internal prospectus data dictionaries and metadata schemas so that all new and updated prospectuses capture the full revised list of ESMA classification data required by the amended RTS.
Review and revise the firm’s incorporation‑by‑reference policy, including standard clauses and cross‑reference tables, to ensure only information categories permitted under the updated RTS are incorporated by reference.
Reconfigure electronic filing tools and interfaces used for submissions to the CSSF (and other NCAs) so that they generate and transmit the updated RTS data set required for classification and ESMA register purposes.
Train legal, capital markets, and product teams involved in prospectus drafting on the new RTS requirements, including examples of acceptable and non‑acceptable incorporation‑by‑reference documents.
What changed
- The amending Delegated Regulation updates the list of data fields required for the classification of prospectuses under Delegated Regulation (EU) 2019/979, impacting how issuers and their advisors...
The RTS amendment revises the list of information that can be incorporated by reference into a prospectus, narrowing or clarifying which external documents (e.g.
Prospectus classification data fields are expected to better align with current ESMA Prospectus Register needs (for example finer product type, offer type, and home/host state metadata), requiring...
The updated incorporation-by-reference list seeks to ensure that only readily accessible and reliable information may be referenced, which will affect how issuers structure cross‑references to annual...

Compliance impact
Non‑compliance can lead to prospectus approval delays, rejection of filings, or required resubmissions, which may disrupt issuance timetables and investor communications. Persistent or material breaches may expose firms and issuers to supervisory measures, sanctions, and reputational risk for failing to meet Prospectus Regulation standards.

CSSF is pressing Luxembourg market participants to complete T+1 readiness surveys by **9 June 2026** and to engage with ESMA’s broader T+1 consultation work, because the EU settlement cycle moves to **T+1 on 11 October 2027** under CSDR. The publication matters because it signals that supervisors are already assessing industry preparedness and that firms must accelerate post-trade process changes, especially around allocations, confirmations, and electronic messaging.
Key dates
02 June 2026
- CSSF publishes the reminder on T+1 readiness, survey participation, and ESMA’s consultation work
09 June 2026 Deadline
- Deadline to complete the CSSF national competent authorities’ T+1 readiness survey
07 December 2026
- Expected application date of the revised ESMA guidelines on standardised procedures and messaging protocols
11 October 2027
- T+1 settlement cycle becomes effective under CSDR
Suggested considerations
Complete the CSSF T+1 readiness survey before 9 June 2026 and ensure the submission accurately reflects the firm’s current operational readiness.
Participate in the EU T+1 Industry Committee second readiness survey to demonstrate engagement with the EU-wide readiness process.
Review the firm’s allocation and confirmation workflows to ensure they can operate within T+1 timeframes.
Replace any reliance on oral, manual, or non-machine-readable communications with electronic, standardised messaging channels unless a temporary technical disruption justifies an exception.
Align internal messaging standards with international messaging protocols used for post-trade communication.
What changed
- CSSF is requiring market participants to complete the national competent authorities’ T+1 readiness survey by 9 June 2026, with responses visible only to CSSF and ESMA.
CSSF is strongly encouraging participation in the EU T+1 Industry Committee second readiness survey to support a Union-wide assessment of market preparedness.
CSSF is flagging that the transition to T+1 settlement on 11 October 2027 under CSDR will require coordinated changes across the trading and post-trading chain.
CSSF is warning that forthcoming amendments to the RTS on Settlement Discipline are expected to be endorsed by the European Commission and will further define operational requirements for the T+1...
ESMA’s revised guidelines on standardised procedures and messaging protocols are intended to make post-trade communication faster, clearer, and more consistent across the EU.
Compliance impact
Non-participation in the surveys will not itself appear to be the substantive T+1 breach, but it will materially weaken supervisory visibility and may invite follow-up scrutiny from CSSF and ESMA. Firms that fail to adapt allocations, confirmations, and messaging processes risk being unprepared for the 7 December 2026 guidance phase-in and the 11 October 2027 settlement-cycle change, which could create settlement fails, operational disruption, and conduct/governance issues.
CSSF reminds Luxembourg market participants that the EU move to a **T+1 settlement cycle under CSDR on 11 October 2027** is now in execution phase and links this directly to concrete supervisory tools: mandatory-like readiness surveys, RTS on Settlement Discipline amendments, and new ESMA post‑trade communication guidelines. For compliance teams, this is a front‑to‑back operating model change: firms must demonstrate T+1 readiness to CSSF/ESMA, transition to fully electronic, standardised post‑trade communication, and align allocations/confirmations processes to tighter regulatory timelines.
Key dates
09 June 2026 Deadline
- Deadline for Luxembourg market participants to complete the CSSF national competent authorities’ T+1 readiness survey
07 December 2026
- Expected application date of revised ESMA guidelines on standardised procedures and messaging protocols and the aligned new RTS on Settlement Discipline requirements on allocations and confirmations
11 October 2027
- Effective date for the transition to a T+1 settlement cycle in the EU under CSDR
Suggested considerations
Identify all group entities and business lines in Luxembourg that are in scope of CSDR T+1 (trading, clearing, settlement, custody, collateral, fund dealing) and formally designate a T+1 programme owner at senior management level.
Complete the CSSF T+1 national competent authorities’ survey in full and by 9 June 2026, ensuring that responses accurately reflect current readiness, key risks, dependencies on third parties, and planned remediation milestones.
Arrange for appropriate internal review and sign‑off (e.g. by Compliance and relevant senior management) of the responses to both the CSSF survey and the EUIC second readiness survey before submission.
Participate in the EU T+1 Industry Committee second readiness survey and ensure the firm’s answers are consistent with the information provided to CSSF and with internal T+1 project documentation.
Perform a comprehensive T+1 impact assessment of front‑to‑back trade flows, covering trade execution, allocation, confirmation, affirmation, clearing, settlement, collateral movements, cash and liquidity management, and corporate actions.
What changed
- The EU settlement cycle for in‑scope financial instruments under CSDR will shorten from T+2 to T+1 with effect from 11 October 2027, materially reducing the time to complete front‑to‑back trade,...
CSSF has launched a national competent authorities’ T+1 readiness survey and sets a firm completion deadline of 9 June 2026 for Luxembourg market participants, treating it as a critical supervisory...
In parallel, CSSF strongly encourages Luxembourg firms to complete the EU T+1 Industry Committee (EUIC) second readiness survey to support an EU‑wide view of T+1 readiness and potential systemic...
ESMA’s final draft amendments to the CSDR RTS on Settlement Discipline will introduce additional operational requirements specifically designed to support T+1 (e.g.
ESMA has launched a consultation on updated guidelines on standardised procedures and messaging protocols for allocations, confirmations and affirmations, explicitly aimed at facilitating the T+1...
Compliance impact
Non‑compliance is high‑impact: failure to prepare for T+1, to respond adequately to supervisory surveys, or to align processes with RTS on Settlement Discipline and ESMA guidelines can lead to increased settlement fails, penalties, supervisory scrutiny, and potential enforcement action. The T+1 change also amplifies operational, liquidity, and conduct risks if firms cannot meet accelerated timelines, making early execution of remediation plans a prudential and conduct priority.
The CSSF has updated its FAQ on the Money Market Funds Regulation (MMFR), making the current guidance version available as **Version 5**. This matters because CSSF FAQs are used to clarify supervisory expectations for MMFs, and firms operating or managing MMFs in Luxembourg should treat the update as a prompt to confirm that prospectus disclosures, weekly transparency information, and reporting arrangements remain aligned with current CSSF practice.
Key dates
21 July 2018
- Article 36(2) transparency requirements apply to MMFs authorised under MMFR as of this date, excluding MMFs benefiting from the transitional provision in article 44(1)
28 August 2018
- CSSF first published the MMFR FAQ, establishing the supervisory clarification framework for MMF questions
18 March 2024
- The CSSF MMF page shows Version 4 of the FAQ and references updated related MMF materials, including ESMA stress test scenario guidance
05 June 2025
- The CSSF webpage shows Version 4 as updated on this date, before the current Version 5 publication
Version 5 / current publication date not stated in the provided extract
- The updated FAQ is now the current CSSF guidance version on the public webpage
Suggested considerations
Review the MMF prospectus and website disclosure architecture to ensure that maturity breakdown and credit profile information are presented in a manner consistent with the CSSF’s current FAQ interpretation.
Confirm that weekly article 36(2) disclosures are scheduled on a controlled and documented day of the week, with escalation procedures for missed or late publication.
Verify that internal credit quality assessment methodology, evidence, and sign-off are documented and available for disclosure or supervisory review.
Reassess whether each MMF in scope is subject to article 36(2) based on its authorisation status and whether any transitional article 44(1) treatment applies.
Align reporting and disclosure controls with the broader CSSF MMF framework, including recurring financial reporting expectations for CSSF-supervised MMF managers.
What changed
- The CSSF has published an updated MMFR FAQ and the current public version is Version 5, indicating that supervisory clarifications have been refreshed since the prior Version 4 publication.
The FAQ continues to address key MMFR transparency topics, including maturity breakdown, credit profile disclosure, and the ability to provide some information via a website link in the prospectus.
The guidance confirms that the manager may choose the day of the week for the weekly disclosure required under article 36(2), which is operationally important for recurring disclosure controls.
The FAQ states that information on internal credit quality assessment must be provided, reinforcing the expectation that the assessment is documented and made available as required.
The FAQ clarifies that article 36(2) applies only to MMFs authorised in accordance with MMFR as at 21 July 2018, and not to MMFs benefiting from the transitional provision in article 44(1).
Compliance impact
The compliance impact is moderate to high because MMFR breaches can create direct transparency, reporting, and governance deficiencies in a regulated fund product. Non-compliance may lead to CSSF supervisory challenge, remediation requests, or enforcement consequences if disclosures or reporting are inconsistent with the regulator’s expectations.
CSSF warning of fraudulent website impersonating authorized alternative investment fund manager. Identity theft and illicit activities pose direct risk to consumers and market integrity. High urgency due to active fraud scheme targeting legitimate firm's reputation and potential investor harm.

The CSSF has formally repealed Circular IML 91/75 with immediate effect through the publication of Circular CSSF 26/912 on 22 May 2026. Compliance teams for Luxembourg UCIs and related structures must now ensure that no policies, procedures or prospectus provisions continue to rely on or reference IML 91/75, and instead rely on the current UCI, SIF, SICAR and EU fund law framework and subsequent CSSF circulars and administrative practice.
Key dates
21 January 1991
- Original Circular IML 91/75 entered into force, setting rules for undertakings governed by the Law of 30 March 1988 on undertakings for collective investment
22 May 2026
- Circular CSSF 26/912 is published and takes effect, repealing Circular IML 91/75 (as amended) with immediate effect and archiving it from the same date
Suggested considerations
Identify and inventory all internal and external documents (including policies, procedures, compliance manuals, prospectuses, offering documents, service agreements and SLAs) that reference Circular IML 91/75 or its amending Circulars CSSF 05/177, 18/697, 21/790, 22/811 and 25/901.
Remove or replace all references to Circular IML 91/75 and its amending circulars in compliance frameworks, manuals, registers of applicable rules and control libraries, ensuring they are mapped instead to the current applicable UCI, SIF, SICAR, AIFM and relevant CSSF circulars.
Perform a gap analysis to confirm that all substantive topics previously governed by IML 91/75 in your framework are now fully covered by current Luxembourg laws, EU fund regulations and up‑to‑date CSSF circulars and FAQs.
Update training materials and onboarding content for compliance, portfolio management, risk and operations staff to reflect that IML 91/75 has been repealed and to direct staff to the current legal and regulatory sources governing UCIs and alternative funds.
Adjust internal audit and compliance monitoring programs so that any test steps or key controls referencing IML 91/75 are updated to reference the applicable current provisions and CSSF administrative practice.
What changed
- Circular IML 91/75, which set out rules for Luxembourg undertakings governed by the Law of 30 March 1988 on undertakings for collective investment, is repealed in full with effect from 22 May 2026...
All amendments to Circular IML 91/75 introduced by Circulars CSSF 05/177, 18/697, 21/790, 22/811 and 25/901 are implicitly repealed as part of the repeal of IML 91/75 itself.
The regulatory expectations previously contained in IML 91/75 are now either superseded by later Luxembourg fund laws (including post‑1988 UCI legislation and regimes for SICARs and SIFs), later CSSF...
The historical link to the Law of 30 March 1988 on undertakings for collective investment is effectively severed at circular level, confirming that the operative framework is now the modern suite of...
IML 91/75 is flagged as archived by the CSSF as of 22 May 2026, clarifying that it has no continuing normative or interpretative value as a live supervisory instrument.
Compliance impact
The immediate compliance risk is moderate: there are no new obligations, but relying on a repealed circular can create legal uncertainty, documentation inconsistencies and supervisory challenges during CSSF inspections. Failure to update frameworks may weaken control design, lead to outdated disclosures and reduce credibility with the CSSF in the event of reviews or thematic inspections.
Repeal of Circular IML 91/75 related to the revision and remodelling of the rules to which Luxembourg undertakings governed by the Law of 30 March 1988 on undertakings for collective investment (“UCI”) are subject
AI Analysis
The CSSF has issued Circular CSSF 26/912, formally repealing Circular IML 91/75 (and its amendments) governing Luxembourg UCIs under the (now repealed) Law of 30 March 1988 on undertakings for collective investment. This is a technical clean‑up measure that removes an obsolete circular from the rulebook and confirms that the 1991 governance, organisational and investment rules under IML 91/75 no longer apply.
Key dates
21 January 1991
- Original Circular IML 91/75 on revision and remodelling of rules applicable to UCIs under the Law of 30 March 1988 is issued (subsequently amended by later circulars)
22 May 2026
- Circular CSSF 26/912 is published and Circular IML 91/75 (as amended by Circulars CSSF 05/177, 18/697, 21/790, 22/811 and 25/901) is repealed and archived
Suggested considerations
Update your regulatory inventory and obligation registers to reflect that Circular IML 91/75 and its amending circulars (CSSF 05/177, 18/697, 21/790, 22/811 and 25/901) have been repealed by Circular CSSF 26/912 as of 22 May 2026.
Verify that your compliance monitoring programmes and internal audit test plans do not rely on requirements sourced from Circular IML 91/75, and re-align any such tests to the currently applicable legal and regulatory standards.
Communicate the repeal of Circular IML 91/75 internally to legal, compliance, risk, product, and fund administration teams to prevent continued reliance on obsolete rules in ongoing or future projects.
For any ongoing remediation, authorisation or approval processes that previously cited IML 91/75 as justification for a control design, reassess and document those controls against the current CSSF requirements that have effectively replaced or superseded the 1991 framework.
Maintain an audit trail evidencing the update of documentation and registers in response to Circular CSSF 26/912, including board or senior management notification where your governance framework requires it for changes in regulatory obligations.
What changed
- Circular IML 91/75, including its amendments by Circulars CSSF 05/177, 18/697, 21/790, 22/811 and 25/901, is formally repealed by Circular CSSF 26/912.
The rules on “revision and remodelling of the rules to which Luxembourg undertakings governed by the Law of 30 March 1988 on undertakings for collective investment are subject” no longer form part of...
Supervisory expectations for Luxembourg UCIs are now to be derived exclusively from the current UCI regime (notably the Law of 17 December 2010 relating to undertakings for collective investment and...
Any internal compliance mappings, policy references, or control frameworks that still cite Circular IML 91/75 or its amending circulars must be treated as referencing repealed guidance and should be...
Compliance impact
The immediate compliance risk is low, as the circular repeals an already outdated framework; however, continuing to reference or rely on Circular IML 91/75 could create documentation inconsistencies, misalignment with current CSSF expectations and weaknesses in regulatory audits or inspections.

ESMA Guidelines on stress test scenarios under Article 28 of the Money Market Fund Regulation – Update 2025 (ESMA50-481369926-30585)
AI Analysis
Circular CSSF 26/911 informs Luxembourg money market fund (MMF) managers that the CSSF is integrating ESMA’s 2025 update of the stress test scenarios under Article 28 of the Money Market Fund Regulation (MMFR), and that these new ESMA Guidelines now form part of the Luxembourg supervisory expectations. The circular repeals and replaces Circular CSSF 25/877 as of 26 May 2026 and requires MMFs and their managers to apply the 2025 stress test parameters for MMF reporting from the reporting date 30 June 2026 onwards, driving immediate model, data, and reporting changes.
Key dates
26 March 2026
- ESMA publishes the English, French, and German translations of the 2025 Guidelines on stress test scenarios under Article 28 MMFR on its website, starting the two‑month period to application
26 May 2026
- Circular CSSF 26/911 enters into force and Circular CSSF 25/877 is repealed and replaced, making the 2025 ESMA Guidelines the applicable stress testing framework in Luxembourg
30 June 2026 Deadline
- MMFs and MMF managers must apply the 2025 ESMA Guidelines for the preparation of the required MMF reporting as from the reporting date 30 June 2026 onwards, meaning that stress test calculations underlying this and subsequent reports must be based on the 2025 parameters
Suggested considerations
Identify all MMFs and MMF mandates in scope of Regulation (EU) 2017/1131 for which the CSSF is the competent authority and confirm that they are currently using the 2024 ESMA stress test framework under Circular CSSF 25/877.
Obtain and review in detail the ESMA 2025 Guidelines on stress test scenarios (ESMA50-481369926-30585) and the annexed parameters as integrated by Circular CSSF 26/911, comparing them line‑by‑line to the 2024 version to map all methodological and parameter changes.
Update the MMF stress testing policy and procedures to reference Circular CSSF 26/911 and the 2025 ESMA Guidelines, including explicit descriptions of the scenarios, calibration choices, modelling techniques, and governance for scenario approval.
Recalibrate stress testing models and tools used for MMFs to reflect the 2025 common reference parameters, ensuring that interest rate shocks, credit spread moves, liquidity shocks, redemption scenarios, and concentration risks are aligned with the new ESMA specifications.
Perform impact analyses on representative MMFs using both 2024 and 2025 parameters to quantify changes in stress outcomes, and prepare internal briefing materials for senior management and boards explaining the impacts on liquidity and risk profiles.

Compliance impact
Non‑compliance with Circular CSSF 26/911 and the integrated 2025 ESMA stress test Guidelines can lead to MMF reporting deficiencies, supervisory findings, and potential risk‑management remediation measures imposed by the CSSF, including expectations to strengthen liquidity and governance. Persistent or material breaches could contribute to more intrusive supervisory engagement, restrictions on MMF activities, or sanctions under the MMFR and Luxembourg supervisory framework.

The CSSF publication highlights AMLA's public consultation on draft Regulatory Technical Standards (RTS) under Articles 16(4) and 17(3) of Regulation (EU) 2024/1624, specifying minimum group-wide AML/CFT requirements and additional measures for subsidiaries and branches in third countries. This matters because it aims to harmonize cross-border AML frameworks, ensuring groups maintain consolidated ML/TF risk views and robust controls, particularly in high-risk third-country operations, impacting EU financial groups' compliance structures. Private sector input is encouraged to align standards with practical operations.[https://www.cssf.lu/en/Document/public-consultation-by-amla-on-the-draft-rts-on-group-wide-minimum-requirements-and-additional-measures-for-subsidiaries-and-branches-in-third-countries/][https://www.amla.europa.eu/amla-consults-group-wide-requirements-and-business-wide-risk-assessment_en]

ESMA Guidelines on Liquidity Management Tools (LMTs) of UCITS and open-ended AIFs (ESMA34-671404336-1364)
AI Analysis
Circular CSSF 26/910 announces the CSSF's application of ESMA Guidelines on Liquidity Management Tools (LMTs) for UCITS and open-ended AIFs, establishing standards for selecting, calibrating, and using LMTs to manage liquidity risks and mitigate financial stability threats. This matters for Luxembourg investment fund managers (IFMs) as it enforces uniform EU-wide supervisory practices under UCITS Directive Article 18a(2) and AIFMD Articles 16(2b)/(2c), holding IFMs primarily accountable for liquidity risk oversight.
Key dates
15 April 2026
Publication and CSSF application date of ESMA Guidelines via Circular CSSF 26/910
Suggested considerations
Review and Update Policies: IFMs must select, calibrate, activate/deactivate LMTs per ESMA guidelines, documenting fair/reasonable ADT calibration (e.g., transaction costs, market impact analysis).
Demonstrate Compliance: Be prepared to show regulators liquidity risk management, including at least one quantitative LMT, one ADT, and condition-specific tools; integrate with UCITS/AIFMD requirements.
Risk Management Integration: Ensure primary responsibility for LMTs, with consistent supervisory application; open-ended SIFs to cross-reference with (EU) 2026/465.
Supervisory Preparedness: Maintain records of previous transactions for market impact estimation and overall LMT rationale.
What changed
- Adoption of ESMA Guidelines: CSSF formally applies ESMA's guidelines (ESMA34-671404336-1364), focusing on LMT selection (e.g., redemption gates, suspension of redemptions/dealings, side pockets),...
Calibration Requirements: IFMs must demonstrate fair and reasonable ADT calibration for normal and stressed conditions, including explicit transaction costs and, where appropriate, estimated implicit...
LMT Recommendations: IFMs should select at least one quantitative-based LMT, one ADT, one for normal conditions, and one for stressed conditions; consider additional measures.
Scope Expansion Recommendation: Open-ended SIFs (not under Part II of the 2010 Law) should consider the circular alongside Commission Delegated Regulation (EU) 2026/465.
Compliance impact
Urgency: High – Published today (15 April 2026), this imposes immediate supervisory expectations on liquidity risk management for Luxembourg's dominant fund sector, where non-compliance risks enforcement under UCITS/AIFMD. IFMs must promptly review LMT frameworks to avoid supervisory scrutiny, especially amid potential market stress.

- Submission deadline for AMLA calibration exercise participants (maintained despite delays; changes to be communicated)
TBD (post Deadline
11 March 2026); - New launch and submission deadlines for all data collections, pending final AMLA questionnaire
Suggested considerations
Monitor CSSF communications for final questionnaire, launch dates, and eDesk access; prepare data on 2025 ML/TF risks and mitigation using current AMLA draft (not for submission).
Selected AMLA calibration participants: Compile and submit quantitative/qualitative data via eDesk by 15 April 2026; attend 13 March webinar.
Non-selected credit/financial institutions: Complete AMLA templates on ML/TF risks/mitigation for 2025 via eDesk upon launch.
Specialised professionals: Prepare CSSF-specific questionnaire ahead of (delayed) 23 February launch.
All: Ensure resources for timely reporting; review internal AML/CFT risk assessments for consistency with EU standards.
What changed
- CSSF adopts AMLA-developed data collection templates for credit institutions, investment firms, and investment fund managers (excluding specialised professionals), replacing its prior questionnaire...
Entities selected for AMLA's mandatory calibration exercise (notified directly by CSSF) must report quantitative and qualitative ML/TF risk data; non-selected entities still report via AMLA templates...

Specialised professionals of the financial sector complete a separate CSSF questionnaire, launching earlier on 23 February 2026 (subject to delay).
Compliance impact
Urgency: High - Mandatory reporting supports CSSF's supervisory strategy and EU AMLA calibration, with non-compliance risking enforcement; delays provide preparation time but require immediate data readiness as final deadlines approach shortly (e.g., potential April submissions). This directly feeds into entity-level ML/TF risk assessments, influencing ongoing supervision and resource allocation.

Table listing the professional activities and the mandates performed
AI Analysis
This CSSF publication is an updated table (in XLSX format) listing standardized professional activities and mandates for members of the management body/governing body and conducting officers, as required under points 105 and 107 of Circular CSSF 18/698. It matters because it ensures consistent, transparent reporting of senior personnel roles in Luxembourg investment fund managers (IFMs), supporting governance, conflict-of-interest management, and CSSF supervisory oversight. Compliance professionals must use this list to standardize disclosures in authorization files and ongoing reporting.
Key dates
23 August 2018
- Publication of underlying Circular CSSF 18/698, setting baseline requirements
14 January 2019
- Original publication of the list
12 March 2026
- Latest update to the list, requiring immediate review and integration into reporting processes[Source URL]
End of May (post Deadline
financial year); - Compliance deadline for Circular 18/698 obligations, including governance reporting (e.g., 5 months after year-end)
Suggested considerations
Download and use the XLSX table: Incorporate the exact list of activities/mandates into internal templates for reporting management body and conducting officer roles[Source URL].
Update authorization and notification files: Include detailed CVs, criminal record extracts, wealth declarations, and organization charts for relevant personnel/shareholders; notify CSSF of changes (e.g., qualifying holdings, guarantees).
Conduct fit-and-proper assessments: Ensure declarations cover all listed mandates, demonstrating no conflicts and adequate resources; perform initial/ongoing due diligence on delegates.
Annual compliance review: Document roles in compliance monitoring plans, training, and reporting to senior management/CSSF; align with delegate oversight (e.g., risk-based monitoring of compliance, audit functions).
Policy updates: Revise governance policies to reflect the updated list, including AML/CFT officer designations and own funds proofs.
What changed
The document was originally published on 14 January 2019 and updated on 12 March 2026, reflecting revisions to the predefined list of professional activities and mandates[Source URL].
Alignment with Circular CSSF 18/698 requirements for IFMs (management companies for UCIs and AIFs), specifying reportable roles like those in collective portfolio management, risk management,...
Emphasis on detailed documentation of mandates to demonstrate fitness, properness, and avoidance of conflicts, including for shareholders with qualifying holdings.
No entirely new requirements introduced, but the update likely incorporates evolving governance expectations, such as enhanced delegate oversight and AML/CFT compliance officer designations.
Compliance impact
Urgency: High – The March 12, 2026 update coincides with today's date, demanding immediate review to avoid supervisory findings during CSSF inspections or authorization processes. Non-compliance risks authorization delays, fines, or reputational damage, as Circular 18/698 emphasizes robust governance in a heightened scrutiny environment for IFMs (e.g., delegate oversight, AML).
This regulatory update provides information on the global situation of undertakings for collective investment in Luxembourg at the end of January 2026. It covers topics related to investment management, reporting, and licensing, which are relevant for asset managers and wealth managers.
Delay in the 2026 AML/CFT standardised data collection
AI Analysis
The CSSF circular letter dated 11 March 2026 announces a delay in its planned AML/CFT standardised data collection exercise originally scheduled for 2026, primarily due to overlap with a concurrent broad-scope data collection by the European Anti-Money Laundering Authority (AMLA). This matters for compliance professionals as it reduces immediate reporting burdens on supervised entities, promotes regulatory simplification, and aligns Luxembourg practices with emerging EU AML/CFT methodologies, allowing firms to redirect resources to the mandatory AMLA exercise.
Key dates
TBD 2026
Potential ad-hoc CSSF questionnaires for essential data points
23 February 2026
Original launch for specialised professionals' CSSF questionnaire
2 March 2026
Original launch date for AMLA calibration exercise data collection via eDesk (now potentially adjusted or paused per delay circular)
11 March 2026
Publication of delay circular, superseding prior timelines; further modalities to be communicated
15 April 2026 Deadline
Original reporting deadline to CSSF for AMLA calibration exercise data
Suggested considerations
Monitor CSSF updates: Await forthcoming communications on revised modalities, new timelines, and any ad-hoc requests via eDesk platform.
Prioritize AMLA obligations: Selected entities must prepare quantitative/qualitative ML/TF risk data per draft RTS on risk assessments (Article 40(2) of Directive (EU) 2024/1640); non-selected entities focus on AMLA templates for 2025 risks/mitigation.
Specialised professionals: Continue preparations for CSSF-specific questionnaire, confirming any shifts post-delay.
Internal review: Assess ML/TF risk profiles, mitigation measures, and reporting readiness in light of EU alignment; update compliance calendars to reflect simplification.
No immediate submissions: Stand down from original 2 March/15 April deadlines unless individually notified otherwise.
What changed
- Postponement of CSSF-specific questionnaire: The CSSF has decided not to proceed with its own AML/CFT standardised data collection for most supervised entities (credit institutions, investment...
Exception for specialised professionals: Specialised professionals of the financial sector (e.g., certain non-credit institutions) remain subject to a CSSF-specific questionnaire, though timelines...
Rationale tied to AMLA calibration exercise: Entities selected for AMLA's 2026 calibration exercise (notified directly by CSSF) must complete it regardless; non-selected entities were to use AMLA...
Potential for ad-hoc requests: CSSF reserves the right to issue targeted questionnaires later in 2026 for essential data points not covered by AMLA. These changes supersede the 12 February 2026...
Compliance impact
Urgency: Medium. The delay alleviates short-term pressure by postponing submissions and reducing dual reporting, enabling resource reallocation to higher-priority AMLA efforts amid EU harmonization. It matters for maintaining a risk-based approach (RBA) under FATF standards, avoiding overburden from overlapping exercises, and preparing for the new EU AML/CFT methodology—non-compliance risks supervisory scrutiny, but the simplification lowers immediate enforcement exposure.

Administrative sanction imposed on a réviseur d’entreprises agréé
AI Analysis
The CSSF imposed an administrative sanction on 2 December 2025 against an approved statutory auditor (*réviseur d’entreprises agréé*) for breaches of professional obligations, likely related to continuing education requirements under Luxembourg's Audit Law, mirroring patterns in recent similar cases. This enforcement action underscores the CSSF's rigorous oversight of audit professionals, emphasizing compliance with ongoing training mandates to maintain audit quality and market integrity. Compliance professionals should note it as evidence of heightened scrutiny on non-delegable professional duties.
Key dates
31 December 2024 Deadline
- Likely reference period end for continuing education non-compliance (inferred from identical prior case)
2 December 2025
- Date of administrative sanction imposition by CSSF
6 March 2026
- Publication date of the sanction notice (today's date, aligning with CSSF practice for transparency under Article 48(2) of the Audit Law)
Suggested considerations
Immediate self-audit: Statutory auditors must verify personal compliance with continuing education hours under CSSF Regulation N°16-10, documenting hours against Article 3(1) requirements and submitting evidence if requested.
Remediation plan: If shortfalls identified, complete deficit training promptly and notify CSSF of corrective measures, as seen in related governance cases where entities implemented remediation.
Internal training programs: Audit firms should enhance monitoring of auditor CPE (continuing professional education) logs, integrating CSSF controls akin to Article 10 of the Audit Law.
Fit-and-proper reviews: Boards and compliance officers assess auditor qualifications, escalating any gaps to CSSF per professional obligations.
Record retention: Maintain verifiable CPE records for at least the reference period plus CSSF inspection windows (typically 3-5 years).
What changed
This is not a regulatory change or new requirement but an enforcement action applying existing rules under point f) of Article 43(1) read with point a) of Article 43(2) and Article 44 of the Law of 23 July 2016 on the audit profession (Audit Law), alongside CSSF Regulation N°16-10 on continuing education.
Compliance impact
Urgency: Medium. This matters as a signal of CSSF's proactive controls on auditor CPE, with fines starting at EUR 1,500 for initial breaches but scaling with severity/duration; repeated actions (e.g., multiple 2025 sanctions) indicate rising enforcement tempo, risking broader audit ecosystem scrutiny. Affected parties face direct fines and reputational harm, while others must prioritize CPE to avoid chain-reaction liabilities in financial reporting.
Administrative sanction imposed on a réviseur d’entreprises agréé
AI Analysis
The CSSF imposed an administrative sanction on 2 December 2025 against an approved statutory auditor (*réviseur d’entreprises agréé*) for breaches of professional obligations, likely related to continuing education requirements under Luxembourg's Audit Law, mirroring patterns in recent similar cases. This enforcement action underscores the CSSF's rigorous oversight of audit professionals, emphasizing compliance with ongoing training mandates to maintain audit quality and market integrity. Compliance professionals should note it as evidence of heightened scrutiny on non-compliance with minimum continuing education hours.
Key dates
31 December 2024 Deadline
- Reference period end for continuing education compliance (inferred from similar case)
2 December 2025
- Date of administrative sanction imposition by CSSF
6 March 2026
- Publication date of the sanction notice
Suggested considerations
Statutory auditors must immediately verify compliance with Article 3(1) of CSSF Regulation N°16-10, ensuring minimum continuing education hours are met for relevant periods.
Audit firms should conduct internal audits of training logs and implement remediation plans, including supplementary training if deficits exist.
All affected parties must report any identified breaches to CSSF proactively and retain evidence of corrective actions, as CSSF controls under Article 10 of the Audit Law can trigger fines.
What changed
No new regulatory changes are introduced; this is an enforcement action applying existing rules under point f) of Article 43(1) read with point a) of Article 43(2) and Article 44 of the Law of 23 July 2016 concerning the audit profession (Audit Law), alongside CSSF Regulation N°16-10 on continuing education for statutory auditors. Breaches typically involve failing to meet the minimum total hours of continuing education by the reference period end (e.g., December 31, 2024, as in a comparable August 2025 case).
Compliance impact
Urgency: Medium. This matters due to the pattern of CSSF enforcement on audit continuing education (e.g., EUR 1,500 fine in August 2025 case for similar breaches), signaling ongoing supervisory controls that could expand to on-site inspections. Non-compliance risks fines, public naming (or anonymous publication per Article 48(2) Audit Law), and reputational damage, but lacks immediate firm-wide deadlines, reducing to medium urgency for proactive reviews.

Administrative sanction imposed on an investment firm
AI Analysis
The CSSF imposed an administrative sanction on 8 October 2025 against an unnamed investment firm, as detailed in a publication released on 4 March 2026. This enforcement action underscores CSSF's rigorous oversight of investment firms, particularly in areas like AML/CFT compliance, conduct rules, and organizational requirements, serving as a warning for similar entities to strengthen cooperation and internal controls. It matters because it highlights escalating fines for repeated or material breaches, potentially influencing supervisory expectations across Luxembourg's financial sector.
Key dates
10 January 2025
- Date of prior depositary oversight fine
4 April 2025 Deadline
- Deadline for submitting CSSF AML/CFT Questionnaire (breach example from similar case)
16 July 2025
- Date of fine imposition for UCITS investment policy breaches
11 September 2025
- Date of fine imposition in comparable AIFM non-cooperation case
8 October 2025
- Date of the sanction in question
Suggested considerations
Enhance cooperation protocols: Implement automated tracking for CSSF requests (e.g., questionnaires) with escalations for reminders; document all responses.
Review investment compliance: Audit broker exposures, valuation processes, and subscription/redemption controls against UCI Law Articles 41-43, 109; suspend dealings if uncertainties arise.
Strengthen governance: Conduct gap analyses on internal controls, risk assessments, and reporting for depositary/oversight functions per AIFM Law Article 19(9) and CDR 231/2013.
Training and monitoring: Roll out firm-wide training on AML/CFT obligations (Article 5(1)) and perform reconciliations of assets/records; prepare for on-site/off-site CSSF inspections.
Self-reporting: Proactively disclose prior breaches to mitigate fine severity.
What changed
No new regulatory changes or requirements are introduced; this is an enforcement action applying existing rules.
Failure to cooperate with CSSF requests, e.g., not submitting required AML/CFT questionnaires by deadlines, violating Article 5(1) of the amended Law of 12 November 2004 on AML/CFT.
Non-compliance with investment policies, organizational requirements, or conduct rules under the UCI Law (e.g., Articles 41, 43, 109), including improper broker exposures or valuation failures.
These reflect ongoing enforcement of established frameworks like the AIFM Law, UCI Law, and AML/CFT Law, with fines calibrated by factors like breach duration, firm size, cooperation level, and prior...
Compliance impact
Urgency: High - This matters due to CSSF's pattern of publicizing nominative sanctions (e.g., Max Gain Capital, Zeus Asset Management), signaling increased scrutiny on investment firms amid AML/CFT and conduct risks. Fines (EUR 10,000–127,500) represent material hits (up to 10% of turnover), with factors like poor cooperation amplifying penalties; firms with similar exposures face elevated inspection risk, especially post-2025 enforcement wave.

The CSSF published guidance on 2 March 2026 specifying minimum documents and information required for assessing shareholding structures of authorised Investment Fund Managers (IFMs) during initial authorisation and subsequent modifications, covering both qualified and non-qualified shareholders. This matters because incomplete submissions will not be processed, potentially delaying authorisations or amendments amid ongoing CSSF scrutiny of governance and ownership in Luxembourg's fund sector.
Key dates
2 March 2026

Enforcement Mechanism: From 2 March 2026, applications lacking these minimums are deemed incomplete, halting analysis until fully submitted.
No prior formalised list existed in this detail for IFMs, shifting from case-by-case to standardised requirements.
Compliance impact
Urgency: High – Effective immediately on publication (2 March 2026), with strict non-processing of incomplete files risking significant delays in time-sensitive authorisations/amendments. Matters for maintaining operational timelines in competitive fund markets, where CSSF oversight of IFM ownership ties to broader governance expectations (e.g., board composition, qualifications).
This CSSF guidance (Version 1.0, published 2 March 2026) specifies the minimum documents and information required for assessing shareholding structures of authorised Investment Fund Managers (IFMs) during initial authorisation or modifications involving qualified and non-qualified shareholders. It standardises submissions to ensure completeness, with incomplete applications rejected until fully provided, enhancing regulatory efficiency and scrutiny of ownership changes. Compliance professionals must prioritise this to avoid delays in authorisation processes for Luxembourg-domiciled IFMs.
Key dates

Enforcement Mechanism: From 2 March 2026, incomplete submissions halt analysis until remedied; CSSF may request additional info.
Compliance impact
Urgency: High – Immediate effect from 2 March 2026 means any ongoing or planned IFM authorisation/modification applications risk delays or rejection if non-compliant, potentially disrupting fund launches or ownership restructurings in Luxembourg's key investment management hub. Matters due to standardised scrutiny on fit-and-proper ownership, aligning with AIFMD governance and reducing administrative back-and-forth.

What changed
The current version (17 February 2026) represents the most recent update to the CSSF's FATF-aligned jurisdiction risk framework. Based on the available search results, the document establishes two primary regulatory categories: High-Risk Jurisdictions (Category 1): Jurisdictions designated by FATF as having strategic deficiencies in their AML/CFT regimes, requiring enhanced due diligence and, where appropriate, counter-measures.
The CSSF has updated its FAQ on portfolio transparency requirements for UCITS ETFs, relaxing disclosure frequency from monthly to quarterly publication of detailed holdings while maintaining daily information sharing with market makers and authorized participants. This change aligns Luxembourg's regulatory framework more closely with Ireland's semi-transparent ETF approach and is designed to attract active asset managers to the Luxembourg domicile by reducing proprietary information exposure.
- Firms should implement changes promptly to ensure compliance with the new quarterly disclosure requirement
Suggested considerations
*For IFMs Managing UCITS ETFs:
*Update disclosure procedures to transition from monthly to quarterly publication schedules for detailed portfolio holdings
*Maintain daily information sharing with APs and market makers to support arbitrage mechanisms—this requirement remains unchanged
*Revise prospectuses to reflect the new quarterly disclosure frequency and confirm compliance with the 30 business-day publication window
