Model Risk Management under CRD VI/CRR III

CRR III has made internal model usage more restrictive: the output floor caps capital savings at 72.5% of the standardised approach, IRB approvals are now granted at exposure class level rather than institution level, and the revised ECB guide to internal models (July 2025) tightens requirements for governance, validation and risk parameter estimation. Banks must keep machine learning models explainable, integrate climate and ESG risks into their models, and provide stricter IT implementation evidence.

Our comprehensive range of model risk management services covers the entire model lifecycle – from initial conception through development and validation to regulatory approval and continuous monitoring.
