The Central Securities Depositories Regulation (CSDR) is a European regulation that was adopted to standardise the rules for central securities depositories.

The aim of the regulation is to stabilise market infrastructures and markets in times of crisis. The CSDR affects both the central securities depositories (CSDs) themselves and the trading partners carrying out transactions involving CSDs.

The regulatory framework provides for the following:

  • EU-wide standardised authorisation and oversight rules for CSDs
  • Settlement periods lasting a maximum of two days
  • Disciplinary measures for late or failed settlements (penalties and mandatory third-party buy-ins)
  • Commitment to dematerialisation and immobilisation
  • Separation of securities accounts, mandatory daily reconciliation processes, book-entry form of securities, use of Legal Entity Identifier Codes.

The implementation of the CSD regulations has been underway since 2014 and is expected to continue until 2025. Due to a planned 12-month postponement, the regulations regarding settlement discipline will now only come into force in February 2022.


What this means for your processes, reporting and data management


The implementation of CSDR-compliant processes and IT structures requires close cooperation and a definition of market practices by all parties involved.

In order to optimise transaction processing at an early stage and to ensure that the prescribed introduction period is adhered to, we recommend introducing the system as early as 2020/2021.
