Central Securities Depository Regulation (CSDR)

The Central Securities Depositories Regulation (CSDR) is the regulation relating to securities settlement and central securities depositaries (CSDs) that entered into force on 17 September 2014.
It applies to CSDs that are based in the European Union and their participants. The principal objectives of the CSDR are to:

  • Increase the safety and efficiency of securities settlement and the settlement infrastructures in the European Union (EU);
  • Harmonise the different CSD rules in the European Union; and
  • Establish an enhanced level playing field among CSDs.

The CSDR is a European-wide regulation, which is directly applicable to all Member States. Statutory Instrument No. 481/2016 (European Union (Central Securities Depositories) Regulations 2016 transposes the regulation into Irish law. The Central Bank of Ireland has been designated the Competent Authority (CA) responsible for carrying out the duties under CSDR for the authorisation and supervision of CSDs established in the State.

Currently the Irish market utilises settlement systems located in a number of different European countries.  Trades in Irish government bonds and Irish corporate securities and some exchange-traded funds (ETFs) are generally settled in Euroclear Bank, located in Belgium. The remaining Irish ETFs are settled in other European CSDs.

Settlement Discipline Regime

One of the key elements of the CSDR is the introduction of an obligation on central securities depositories (CSDs) to impose cash penalties; on participants in their securities settlement systems that cause settlement fails.

The new cash penalties; regime, which is intended to serve as an effective deterrent for participants that cause settlement fails and to incentivise those in the settlement chain to settle trades in a timely manner, entered into force on 1 February 2022.

One of the measures of the new settlement discipline regime established under the CSDR is the introduction of new mandatory buy-in rules. However the European Commission announced in November 2021 that the application of these new rules have been delayed and will not apply from 1 February 2022.


There is a requirement in the CSDR that all newly issued securities of quoted companies admitted to trading in the EU hold all shares through a CSD from 1 January 2023 and all existing transferrable securities of quoted companies admitted to trading in the EU must be represented in book entry from 1 January 2025. Therefore, by 2023, all newly issued securities will have to be in a dematerialised format, whilst by the start of 2025, all traded securities will need to be held electronically.

Immobilisation and dematerialisation should not imply any loss of rights for the holders of securities and should be achieved in a way that ensures that holders of securities can verify their rights.

In order to facilitate the implementation of this requirement, holders of securities in physical certificate form - whether shares, debt securities or units in collective investment schemes should contact their broker/issuer in the first instance.
