Circular CSSF-CPDI 25/47
CSSF
On 6 October 2025, the CSSF (Commission de Surveillance du Secteur Financier) published Circular CPDI 25/47, which mandates a quarterly survey of covered deposits held by credit institutions under Luxembourg law, by POST Luxembourg, and by Luxembourg branches of third-country institutions, as of 30 September 2025.
Key Points
The circular’s scope and methodology remain consistent with previous surveys; only the reference date and deadline have changed.
“Covered deposits” and “eligible deposits” are defined by Article 163 of the amended law of 18 December 2015.
Deposit aggregations such as omnibus accounts, fiduciary accounts, trust accounts, etc., must be carefully handled: institutions should allocate amounts among identifiable entitled persons.
Excluded from the survey are accounts denominated in precious metals (e.g. gold, silver) and in virtual currencies (e.g. Bitcoin, Ether).
Reporting Requirements & Deadline
Institutions must submit data by 20 November 2025 at the entity level (including branches in other Member States).
The data form the basis for calculating both the administrative contribution and the Resolution Fund contribution.
Submission channels: via CSSF eDesk or by uploading a structured file via S3.
If an institution has no deposits to report, it must still submit a report indicating “0.”
Any errors or omissions discovered later must be communicated promptly to the CPDI via email.
