The CSSF’s professional secrecy and its legal exceptions (only in French)

The regulator reminds stakeholders that it acts exclusively in the public interest and that its staff handle highly confidential information, the disclosure of which could affect financial stability. For compliance teams, this is an informational update rather than a new rule: it reinforces that the CSSF will publish sanctions only within strict legal limits while maintaining a robust confidentiality regime. Firms should review internal protocols for handling confidential supervisory information, ensure staff understand restrictions on external disclosures, and monitor CSSF communications for any future shifts in enforcement transparency.

No immediate filings or operational changes are required, but senior management should be aware that supervisory interactions remain protected and that public statements about regulatory matters should be carefully assessed. The clarification may help firms better anticipate the CSSF's disclosure posture during investigations or sanction proceedings. RegCanary view: low urgency, high relevance for regulatory affairs and legal teams; use this as a prompt to refresh confidentiality training and escalation procedures.
