The European Securities and Markets Authority has published three final reports containing draft technical standards under the Central Securities Depositories Regulation (CSDR) Refit, covering supervisory information to be provided by EU central securities depositories (CSDs), the test for when an EU CSD is of substantial importance in a host Member State, and notification requirements for third-country CSDs. For the review and evaluation process, the standards aim to harmonise the information CSDs must share with national competent authorities and include a one-year implementation period for new reporting items that require changes to CSD IT processes. The host Member State assessment sets out criteria and the related data collection process for indicators used to determine when a CSD’s activities are of substantial importance, which will be used to identify the CSDs for which supervisory colleges must be established. For third-country CSDs, the standards seek to streamline the information to be notified to support an accurate understanding of the provision of notary, central maintenance and settlement services in the EU. The draft technical standards have been submitted to the European Commission for adoption.
