ECB Guide to Internal Models: Strategic Orientation for Banks in the New Regulatory Landscape
The July 2025 revision of the ECB guidelines requires banks to strategically realign internal models. Key points: 1) Artificial intelligence and machine learning are permitted, but only in an explainable form and under strict governance. 2) Top management is explicitly responsible for the quality and compliance of all models. 3) CRR3 requirements and climate risks must be proactively integrated into credit, market and counterparty risk models. 4) Approved model changes must be implemented within three months, which requires agile IT architectures and automated validation processes. Institutes that build explainable AI competencies, robust ESG databases and modular systems early on transform the stricter requirements into a sustainable competitive advantage.
