LUXEMBOURG — The Commission de Surveillance du Secteur Financier (CSSF) has announced a change to the transmission process for Money Market Fund (MMF) reporting, effective September 1, 2025. Investment fund managers in Luxembourg will now be required to use a new, streamlined, and free-of-charge system for their MMF submissions.
As of the effective date, the CSSF will exclusively accept MMF reports exclusively through two designated methods. The new procedures are designed to modernize the reporting process and are available at no cost to fund managers.
The two mandated transmission methods are:
- eDesk ZIP file upload: A ZIP file, which must contain the report in an XML format, can be submitted manually through the dedicated eDesk procedure.
- Automated API submission: Firms can also submit the same ZIP file and XML report automatically via an API using the S3 protocol, allowing for an integrated and efficient workflow.
This change ensures a standardized and secure reporting channel for all MMF data. To assist fund managers with the transition, the user guide for the eDesk card has been updated with detailed instructions. For any questions or support, managers are advised to contact the CSSF directly at edesk@cssf.lu.
