On 3 July 2025, the European Commission adopted a Commission Delegated Regulation supplementing the Capital Requirements Regulation (CRR) with regard to regulatory technical standards (RTS) specifying the conditions for assessing the materiality of extensions of, and changes to, the use of alternative internal models, and changes to the subset of the modellable risk factors.

The final draft RTS specify the conditions for assessing the materiality of extensions and changes to the use of alternative internal models and changes to the subset of the modellable risk factors. As per Article 325az(8) of the CRR, the final draft RTS differentiate between material extensions and changes, to be approved by Member State competent authorities (NCAs), and non-material extensions and changes, to be notified to NCAs four weeks in advance.

The Commission Delegated Regulation enters into force on the twentieth day following that of its publication in the Official Journal of the European Union.
