EU Regulations in Luxembourg
How key EU financial regulations apply in the Luxembourg jurisdiction — local competent authorities, transposition status, and national specificities.
MiCAR in Luxembourg
Transitional period — deadline 1 July 2026
The CSSF is the competent authority for MiCAR in Luxembourg. Luxembourg had already established a regulatory framework for virtual asset service providers (VASPs) through its 2004 Financial Sector Law (as amended). Existing VASPs registered with the CSSF must transition to full MiCAR authorisation by 1 July 2026. The CSSF has issued specific guidance for the MiCAR application process.
DORA in Luxembourg
Applicable since 17 January 2025
The CSSF supervises DORA compliance for Luxembourg financial entities. Given Luxembourg's role as a major fund and banking centre, DORA has significant impact — particularly for management companies, depositaries, and fund administrators that handle critical ICT operations. The CSSF previously issued Circular 20/750 on ICT risk management, which is now superseded by DORA.

AIFMD II transposition by 16 April 2026

CRR / CRD in Luxembourg
CRR III phased implementation from 2025

Frequently Asked Questions
Who regulates financial services in Luxembourg?
The CSSF (Commission de Surveillance du Secteur Financier) is the primary financial supervisor in Luxembourg, responsible for banks, investment firms, fund managers, payment institutions, and CASPs. The CAA (Commissariat aux Assurances) supervises insurance and reinsurance undertakings. Luxembourg uses an integrated supervisory model where the CSSF handles both prudential and conduct-of-business supervision for most financial entities.
Why is Luxembourg important for fund regulation?
Luxembourg is the largest fund centre in Europe and the second largest globally, with over EUR 5 trillion in fund assets under management. It is the leading European domicile for UCITS funds, alternative investment funds (SIFs, SICARs, RAIFs), and securitisation vehicles. The CSSF supervises fund managers under the AIFMD (transposed via the 2013 AIFM Law) and UCITS Directive (transposed via the 2010 UCI Law). AIFMD II transposition by April 2026 will significantly impact Luxembourg-based managers.
How does MiCAR apply in Luxembourg?
The CSSF is the MiCAR competent authority in Luxembourg. Luxembourg had previously regulated virtual asset service providers (VASPs) under amendments to the Financial Sector Law of 1993. Existing CSSF-registered VASPs must obtain full MiCAR CASP authorisation by 1 July 2026. The CSSF has published guidance on the application process and conducts pre-application meetings.
What DORA obligations apply to Luxembourg fund managers?
Luxembourg-based UCITS management companies and AIFMs are in scope of DORA since 17 January 2025. They must implement ICT risk management frameworks, incident reporting procedures, digital operational resilience testing, and third-party ICT risk management. The CSSF's previous Circular 20/750 on ICT risk is superseded by DORA. Given Luxembourg's concentration of fund service providers (administrators, transfer agents, depositaries), third-party ICT risk management is particularly critical.
What is the Luxembourg RAIF?
The Reserved Alternative Investment Fund (RAIF) is a Luxembourg fund vehicle introduced by the law of 23 July 2016. RAIFs combine the flexibility of the SIF/SICAR regimes with the advantage of not requiring direct CSSF approval — instead, they must appoint an authorised AIFM. RAIFs can invest in any asset class, offer multiple compartments, and are subject to AIFMD through their manager. They have become a popular structure for private equity, real estate, and debt fund strategies.
How do I find CSSF-regulated entities in Luxembourg?
The CSSF maintains a public register of all entities it supervises, searchable on cssf.lu. The register covers credit institutions, investment firms, fund managers (UCITS management companies, AIFMs), payment institutions, e-money institutions, CASPs, and other regulated professionals. Each entry shows the entity's authorisation date, regulatory scope, and licence type under the Financial Sector Law. For MiCAR-specific authorisations, the CSSF also publishes a separate list of authorised CASPs updated after each supervisory board decision. Entities pending authorisation or in the transitional period are listed separately.
