CIRCULAR CSSF-CPDI 25/47 Survey on the amount of covered deposits held on 30 September 2025 2/4 Circular CSSF-CPDI 25/47 Survey on the amount of covered deposits held on 30 September 2025 To the members of the Fonds de garantie des dÈpÙts Luxembourg Luxembourg, 6 October 2025 Ladies and Gentlemen,

1. The aim of this circular is to carry out the regular survey on deposits, and more particularly on covered deposits, as held by credit institutions incorporated under Luxembourg law, POST Luxembourg for its provision of postal financial services, and Luxembourg branches of credit institutions having their head office in a third country (hereinafter referred to as “institutions”) as at 30 September 2025.
2. We would like to draw your attention to the fact that the present circular has not undergone any change regarding the content and terms and conditions of the survey process on the amount of covered deposits save for the explanation on the usefulness of the data collection for the purpose of computing the administrative contribution. In comparison with the previous circular regarding the quarterly survey on the amount of covered deposits, changes are therefore mainly limited to the date of reference and deadline. Attached specifications remain unchanged.
3. A definition of “covered deposits” and “eligible deposits” can be found in Article 163 of the amended law of 18 December 2015 on the failure of credit institutions and certain investment firms (hereinafter referred to as “Law of 18 December 2015”). The provisions of Circular CSSF￾CPDI 16/02 as amended by Circular CSSF-CPDI 23/35 shall be taken into account, in particular with regard to the exclusions of structures assimilated to financial institutions, as well as the treatment of accounts whose holder is not absolutely entitled to the sums in the account (omnibus accounts, accounts of fiduciaries, accounts held by trusts, third-party accounts, sub-accounts, segregated accounts, etc.). In case the account holder differs from the persons that are absolutely entitled to the sums in the account, the FGDL members shall take reasonable measures to regularly obtain information on the number of identifiable and eligible persons entitled to the sums in the account as well as on the amounts to which each of them is entitled, so as to accurately report the amount of covered deposits and covered claims to the Conseil de protection des dÈposants et des investisseurs, hereinafter “CPDI”. In the absence of a reliable and up to-date estimate of the above-mentioned information, the FGDL members report the total amount of omnibus accounts opened in their books. We also remind you that the breakdown into natural and legal persons of omnibus accounts or other types of accounts whose holder is not absolutely entitled to the sums in the account, shall be made according to the legal status of the holder of such accounts. We remind the FGDL members that neither accounts denominated in units of precious metals, such as gold (XAU) or silver (XAG), nor accounts denominated in virtual currencies, such as Bitcoin or Ether, constitute eligible deposits for the purpose of the FGDL guarantee. Hence such accounts shall not be reported under this data collection.

FGDL members are requested to provide the data at the level of their legal entity, comprising data from branches located within other Member States1 , by 20 November 2025.

Institutions are required to submit the reporting through one of the following means of communication: • Via CSSF eDesk platform which is also accessible through the CSSF website; or • Via the submission of a structured file through S3 (“simple storage service”) protocol.
