The European Banking Authority (EBA) will start the central validation of the International Swaps and Derivatives Association Standard Initial Margin Model (ISDA SIMM) on 1 March 2026. The Decision on arrangements for ISDA SIMM validation, published today sets out the operational framework governing the EBA’s new validation function. This marks a key milestone in the implementation of the EBA’s new role as central validator of pro forma models, aimed at ensuring consistent, robust and transparent supervisory oversight of initial margin models across the EU.
