ECB streamlines approval of banks’ internal model changes
EU banks can implement internal model changes faster from October

Change
ECB Banking Supervision will allow banks to implement eligible material credit-risk internal model changes shortly after submitting a complete application package from 1 October 2026.
Why it matters
The new approach shifts eligible material model changes from ex ante assessment to faster permission with ex post supervisory review. Banks must obtain internal-control confirmation before implementation, and capital benefits from lower risk weights remain constrained by floors until targeted ECB assessment is complete.
Implications
- — EU banks using internal models for credit-risk capital requirements must prepare complete model-change application packages because ECB will permit eligible changes shortly after submission from 1 October 2026.
- — Internal model validation and control functions must confirm regulatory compliance and implementation readiness before model changes are used because ECB made that confirmation a condition of fast implementation.
- — Capital planning teams must apply the ECB floor to approved model changes that reduce risk weights because capital benefits can be lifted only after targeted ECB assessment.
