Recital 1

(1)The Centralised Securities Database (CSDB) is a single information technology infrastructure operated jointly by the members of the European System of Central Banks (ESCB), including national central banks of the Member States whose currency is not the euro (hereinafter ‘non-euro area NCBs’) where such non-euro area NCBs voluntarily participate in the operation of the CSDB. The CSDB stores item-by-item data, in particular, data on securities, their issuers, prices and ratings. The main processes of the CSDB’s operation comprise input data provision, processing of that input data, carrying out data quality management (DQM) and production and dissemination of output data consisting of item-by-item data and aggregate information. A number of changes to these processes require the adoption of a new Guideline to ensure that there are clear and certain arrangements for the governance of the CSDB. In the interest of legal certainty, Guideline 2012/689/EU of the European Central Bank (ECB/2012/21) ² and Guideline (EU) 2021/834 of the European Central Bank (ECB/2021/15) ³ , which to date have governed the data quality management framework of the CSDB and the reporting of statistical information on securities issues, should be repealed.
