Circular CSSF 25/881 (as amended by Circular CSSF 26/915) (Updated) amending Circular CSSF 20/750 on requirements regarding information and communication technology (ICT) and security risk management
CSSF updates ICT and security risk management requirements: CSSF Circular 25/881 amends the Luxembourg framework for ICT and security risk management to reflect the application of DORA and reduce regulatory overlap. It narrows the relevant EBA Guidelines and maintains specific requirements for PSPs and non-DORA entities. The circular was further amended in August 2026 to reflect DORA's application to certain third-country branches.

CSSF extends LMT activation module to notifications of suspension of redemptions
On 18 September 2026, the CSSF announced that, from 21 September 2026, the activation and deactivation of a suspension of redemptions only must be notified through the CSSF eDesk “LMT activation” module. The requirement applies to Luxembourg UCIs, SIFs and SICARs within the scope of the communication. While a redemption-only suspension is not itself an LMT under the Luxembourg Law of 3 March 2026, the CSSF has integrated it into the LMT notification module. Existing administrative and documentation requirements remain unchanged. Compliance action: ensure relevant procedures and responsible teams are ready to use the eDesk module as of 21 September 2026.
