Reminder: new method of transmitting reporting from settlement internalizers (CSDR Art. 9)

CSSF

(Published January 30, 2025, updated April 2, 2025)

As a reminder, as of July 1, 2025, the method of transmitting the reporting of settlement internalizers (CSDR Art.9) is changing.

Reports will be collected exclusively through the two methods below, and free of charge:

  • Submission of the ZIP file (including the report in XML format) in the dedicated eDesk process

  • Automated submission of ZIP file (including report in XML format) via API (S3 protocol)

From July 1, 2025 :

  • Quarterly reports covering the current reference period (2nd quarter 2025) as well as all resubmissions covering previous reference periods are affected.

  • No further CSDR Art.9 reporting will be accepted through historical external channels.

We will soon communicate the deadlines for opening pre-production for your possible tests, as well as the corresponding user guide.

For any questions, please contact edesk@cssf.lu.
