CSSF Circular 26/906, published on 20 January 2026, establishes detailed requirements for central administration, internal governance, and risk management for payment institutions (PIs) and electronic money institutions (EMIs) in Luxembourg, repealing prior circulars IML 95/120, IML 96/126, IML 98/143, and CSSF 04/155. It clarifies application of the amended Law of 10 November 2009 on payment services, emphasizing robust governance amid sector growth to ensure safety, efficiency, and trust.

Central administration, internal governance and risk management
Circular CSSF 26/906, published on 20 January 2026, consolidates and clarifies Luxembourg's rules on central administration, internal governance, and risk management specifically for payment institutions, electronic money institutions, and account information service providers. It repeals prior circulars (IML 95/120, IML 96/126, IML 98/143, and CSSF 04/155) to address growth in transaction volumes by mandating robust governance, control functions, and risk processes, enhancing safety, efficiency, and trust in these services. This matters for compliance professionals as it strengthens defenses against financial crime, operational risks, and supervisory scrutiny in a high-growth sector. #

Update of Circular CSSF 24/850 on the practical rules concerning the descriptive report and the self-assessment questionnaire to be submitted on an annual basis by support PFS, as well as the engagement of the réviseurs d’entreprises agréés (approved statutory auditors) of support PFS and practical rules concerning the management letter and the separate report to be drawn up on an annual basis.
Circular CSSF 25/903 updates Circular CSSF 24/850, refining practical rules for support Professional of the Financial Sector (support PFS) in Luxembourg regarding their annual descriptive report, self-assessment questionnaire, and the roles of approved statutory auditors (réviseurs d’entreprises agréés).

This matters for support PFS as it enhances supervisory oversight, ensures consistent reporting quality, and strengthens internal controls, directly impacting compliance and audit processes amid CSSF's focus on robust PFS supervision. #

Circular CSSF 24/850, as amended by Circular CSSF 25/903, establishes practical rules for support Professional of the Financial Sector (support PFS) in Luxembourg to submit annual descriptive reports and self-assessment questionnaires, while also defining the roles of approved statutory auditors (réviseurs d’entreprises agréés) in issuing management letters and separate reports. This guidance standardizes supervisory reporting and audit processes to enhance oversight of support PFS, which provide essential back-office services to authorized PFS. It matters because non-compliance risks supervisory sanctions, reputational damage, and operational disruptions for entities reliant on support PFS structures. #
