The finalisation of the Basel III framework - known as Basel IV - is imminent: on 27 October 2021, the European Commission presented the draft of an EU banking package that is to implement Basel IV into European law, including CRR III (Capital Requirements Regulation). The European Council (October 2022) and the European Parliament (January 2023) have now also published their positions, meaning that the final negotiations can begin.
Basel IV is the collective term for regulatory changes to further develop the capital adequacy framework for banks in accordance with the requirements of the Basel Committee on Banking Supervision (BCBS). In addition to the general objective of ensuring financial stability, the finalisation of Basel III in the EU is also intended to strengthen the risk-based capital framework, focus on ESG risks and harmonise supervisory powers and instruments.
While CRR II still had a moderate impact on the calculation of RWA (risk-weighted assets), CRR III will result in significant changes to RWA and capital requirements. For European banks in particular, it means potential changes in profitability, in the design of individual products and their pricing as well as in the implementation of significant requirements for IT and reporting solutions.
The most important changes for institutions relate in particular to the requirements for calculating RWA for credit risk, operational risk, CVA risk (credit valuation adjustment) and, in some cases, market risk. The gradual introduction of the so-called output floor, which limits the possible relief effects of users of internal models on RWA, is also moving into focus. In future, they will have to apply all standardised approaches in parallel alongside the internal models.
