ECB Allows Faster Credit Risk Model Changes Starting October
Summary
The European Central Bank announced changes to streamline supervision of banks' internal credit risk models, effective October 1. Banks may now implement material model changes shortly after submitting complete applications without maintaining parallel models. When changes reduce risk weights, capital benefits face a supervisory floor cap until the ECB completes on-site review, though on-site investigations no longer automatically accompany material changes.
What changed
The ECB has introduced a streamlined approval process for banks' internal credit risk models, effective October 1. Banks may now implement material model changes shortly after submitting complete applications, eliminating the previous requirement to maintain both old and new models in parallel while awaiting supervisory approval. The revised approach requires banks' internal control functions to confirm regulatory compliance before implementation.
Affected banks using internal ratings-based approaches for credit risk will benefit from faster model changes, but must implement robust internal validation processes. Where model changes reduce risk weights and capital requirements, any resulting capital benefit will be capped by a supervisory floor until the ECB completes a targeted on-site review. Banks in higher risk or sensitive cases may still be subject to the standard approval process with dedicated on-site investigation requirements.
What to do next
- Monitor ECB implementation guidance for internal model change procedures
- Review internal control function confirmation processes for model changes
- Assess impact on capital planning timelines for model modifications

ECB Streamlines How It Supervises Banks' Internal Models
A&O Shearman + Follow Contact LinkedIn Facebook X Send Embed
The European Central Bank (ECB) has announced changes to streamline the supervision of banks' internal models for credit risk, aimed at making the approval process for material model changes faster and more predictable while maintaining prudential safeguards. From 1 October, banks will be permitted to implement material changes to their internal models for credit risk shortly after submitting a complete application package. This will allow banks to implement model changes quickly, without having to maintain old and new models in parallel while awaiting supervisory review. This is subject to confirmation by the bank's internal control function that the revised model complies with regulatory requirements and that the bank is ready to implement the change. Where changes lead to lower risk weights, expedited approval will still apply, but any capital benefit will be capped by a supervisory floor applied to all approved model changes, and only lifted once the ECB completes a targeted on site review. The ECB will retain the option to apply the standard approval process in higher risk or sensitive cases, with banks waiting for the outcome of a dedicated on site investigation. Material model changes will no longer automatically trigger an on-site investigation. On the same day, the EBA also published final draft regulatory technical standards amending the framework for assessing the materiality of changes to internal ratings based models.
