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.
