The European Securities and Markets Authority has published final reports on two sets of Regulatory Technical Standards (RTS) specifying requirements for central counterparties (CCPs) to obtain initial authorisation, extend an authorisation and validate changes to models and parameters, implementing supervisory streamlining measures introduced by EMIR 3. One RTS package sets the conditions for extensions of authorisation and lists the documents and information required in applications for initial authorisation and for extensions. The second RTS package sets the conditions for validating changes to CCPs’ models and parameters and specifies the documents and information required for applications for those validations. The final reports reflect feedback from ESMA’s public consultations on the draft RTS in Q1 2025. The RTS will be submitted to the European Commission for endorsement and will then be subject to scrutiny by the European Parliament and the Council.
