UK Basel 3.1: Reporting changes
On 20 January 2026, the PRA published Policy Statement (PS) 1/26, setting out the final Basel 3.1 policy package. This comprises PRA Rulebook instruments, supervisory statements, statements of policy, and the associated reporting and disclosure templates and instructions.
The package largely confirms the near-final policy, with only minor amendments, corrections and clarifications (alongside targeted market risk updates consulted on separately).
Basel 3.1 will take effect on 1 January 2027, while the FRTB Internal Model Approach will come into effect on 1 January 2028.
This section provides an overview of the changes to the reporting requirements. For each template, the ‘change type’ is highlighted as ‘New’ (where a new template is introduced), ‘Amended’ (where the current template is modified), and ‘Deleted’ (where the current template is discontinued).
Reporting changes are listed below based on the risk category:
1. Credit Risk
Key reporting changes for the Credit Risk - Standardised Approach are outlined below:
As part of the publication of the final rules, the PRA also removed the reporting requirement under Article 430a, specifically template C 15.00 ‘reporting losses from exposures secured by immovable property’.
2. Operational Risk
All existing operational risk approaches [Basic Indicator Approach (BIA), Standardised Approach (SA), and Advanced Measurement Approach (AMA)] are replaced by the new Standardised Approach (SA). As a result, current templates will also be replaced by a new one. A summary of the reporting requirements of the new template is outlined below:
3. Credit Valuation Adjustment (CVA) Risk
The following three new methodologies have been introduced to replace the current framework:
Alternative Approach (AA-CVA)
Basic Approach (BA-CVA)
Standardised Approach (SA-CVA)
As a result of this, the current template is replaced by three new templates. A brief summary of reporting requirements of new templates is outlined below:
4. Market Risk
The following changes in the calculation of the own funds requirements for Market Risk are triggering changes to the reporting requirements as well:
The existing Standardised Approach has been recalibrated and renamed as the Simplified Standardised Approach (SSA)
Introduced a new more comprehensive standardised approach - the Advanced Standardised Approach (ASA)
Introduced a new Internal Model Approach (IMA), replacing the current modelled approach
