European Banking Authority
5 August 2026
The EBA is consulting on a standardised reporting framework for firms using ISDA’s Standard Initial Margin Model (SIMM) for non-centrally cleared OTC derivatives. The proposal supports the EBA’s role as the central validator of pro forma initial-margin models under EMIR, a function it began on 1 March 2026.
The framework would collect consistent information on model use and performance, support ongoing monitoring, and provide data for calculating validation fees. It is designed to be proportionate: firms with less significant OTC trading activity would submit lighter, annual reports. The consultation closes on 2 November 2026.
Following feedback, the EBA plans to adopt a Decision by the end of 2026. The first reporting reference date is expected in December 2027, with data collection beginning in the first quarter of 2028.

EBA, EIOPA and ESMA propose amendments to bilateral margin requirements
3 August 2026
The EBA has issued a no-action letter and technical clarifications to support consistent implementation of the EU’s revised market-risk framework under the Fundamental Review of the Trading Book (FRTB). The measures will apply once the European Commission’s Delegated Act enters into force and becomes effective from 1 January 2027 for three years.
The EBA recommends that national supervisors do not prioritise enforcement concerning rules on the boundary between the banking and trading books, internal risk transfers between them, and certain related reporting requirements. This is intended to prevent banks using the new institution-specific multiplier from having to implement multiple, complex versions of the boundary framework, while avoiding an uneven playing field for other EU banks.
The EBA also provides technical considerations on material implementation issues and clarifies the treatment of institutions for supervisory benchmarking.
Prudential Regulation AuthorityPS18/26 – Solvency UK: Post-implementation reporting and disclosure amendments and Own Funds permissions update
29 July 2026
PS18/26 finalises targeted updates to the UK Solvency II reporting, disclosure and Own Funds framework following the 2024 Solvency UK reforms. Effective for reporting reference dates from 31 December 2026, the changes apply to UK Solvency II firms, including Lloyd’s, insurance groups and holding companies, with some measures also affecting third-country branches.
Key changes improve reporting clarity, correct errors and inconsistencies, update selected templates, and allow firms to use NACE 2.1 classifications from the December 2026 reference date.
The PRA will also move Matching Adjustment Asset and Liability Information Return (MALIR) reporting from Excel to XBRL, reduce certain cashflow reporting frequency, and require third-country branches to submit one year of projected FSCS liabilities data. Finally, the PRA removes the permission requirement for classifying equity-accounted subordinated liabilities as own funds, retaining supervisory oversight through pre-issuance notifications.
This item is related to PRA Solvency II.
Federal Reserve
31 July 2026
The Federal Reserve has proposed modernising regulations for mutual banking organisations, which are owned by depositors rather than shareholders. More than 90% of these institutions have under $3 billion in assets.
The proposal would comprehensively update the framework, clarify which instruments qualify as regulatory capital, reduce procedural requirements, and give certain mutual banks greater flexibility to raise capital.
The Fed said the changes aim to help mutual banks grow and better serve their communities while preserving their depositor-owned structure and supporting diversity in the U.S. banking system. Comments are due 60 days after the proposal is published in the Federal Register.
