Communiqué
The CSSF's January 2026 enforcement report documents the results of its 2025 examination campaign on 2024 financial and non-financial disclosures by issuers under Luxembourg's Transparency Law. This publication is critical for compliance professionals because it reveals systematic compliance gaps across financial reporting (IFRS), sustainability reporting (ESRS), and Alternative Performance Measures (APMs), with 27% of enforcement decisions resulting in injunctions for non-compliance.
Administrative sanction imposed on BigRep SE
The CSSF imposed a €10,000 administrative fine on BigRep SE on 12 January 2026 for failing to publish its half-yearly financial report as of 30 June 2025, as required under Article 4 of Luxembourg's Transparency Law of 11 January 2008 (as amended). This enforcement action underscores the CSSF's rigorous supervision of periodic disclosure obligations for issuers with Luxembourg as their home Member State, serving as a reminder of the consequences for non-compliance with transparency requirements. Compliance professionals should note this as evidence of ongoing CSSF scrutiny on timely reporting, with potential fines scaled based on circumstances per Article 26a. #
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
Circular IML 91/75, as amended up to CSSF Circular 25/901, consolidates and modernizes the supervisory framework for Luxembourg Part II UCIs, SIFs, and SICARs, refining rules on diversification, borrowing, risk-spreading, and disclosures while tailoring requirements to investor profiles. It matters because it streamlines fragmented regulations, enhances fund competitiveness, and formalizes CSSF expectations without mandating immediate changes for pre-existing funds, reducing compliance burdens while promoting transparency and flexibility. This update aligns administrative practices with market realities, repealing outdated circulars to eliminate ambiguity. #
Rules applicable to undertakings for collective investment when they employ certain techniques and instruments relating to transferable securities and money market instruments
Circular CSSF 08/356, as amended by Circular CSSF 25/901, establishes detailed rules for Luxembourg undertakings for collective investment (UCIs), including UCITS and alternative investment funds (AIFs), on the use of techniques and instruments relating to transferable securities and money market instruments, such as securities lending, repo transactions, and over-the-counter (OTC) derivatives. It matters because it ensures investor protection, risk management, and market stability by imposing strict eligibility, collateral, and operational requirements, aligning Luxembourg funds with EU standards under UCITS and AIFMD directives. Compliance is critical for Luxembourg-domiciled funds engaging in these activities to avoid regulatory sanctions and operational disruptions. #
Provisions relating to credit institutions and investment firms of EU origin established in Luxembourg by way of branches or exercising activities in Luxembourg by way of free provision of services
Circular CSSF 07/325, as amended by Circulars CSSF 21/765, CSSF 22/827, and most recently CSSF 25/898, establishes supervisory requirements for EU credit institutions and investment firms operating in Luxembourg via branches or free provision of services (FOPS). It matters for compliance professionals as it defines CSSF's host authority role, notification obligations, reporting, and enforcement powers, ensuring alignment with CRD and MiFID II while adapting to evolving EU rules. #
Update of Circular CSSF 07/325 on Provisions relating to credit institutions and investment firms of EU origin established in Luxembourg by way of branches or exercising activities in Luxembourg by way of free provision of services, as amended by Circulars CSSF 21/765 and CSSF 22/827
Circular CSSF 25/898 updates Luxembourg's supervisory framework for EU-origin credit institutions and investment firms operating in Luxembourg through branches or free provision of services. This amendment enhances the self-assessment questionnaire (SAQ) used by the CSSF to align supervisory oversight with current regulatory priorities, particularly adding UCI administration as a new thematic module. The update reflects the CSSF's evolving supervisory focus and requires affected institutions to demonstrate compliance with expanded assessment criteria.
