Mark Your Calendar: Key Dates for Basel 3.1 and SDDT. It has been approximately three months since the PRA released the second part of its near-final rules for implementing the Basel 3.1 standards in the UK. With the official implementation date of 1 January 2026 less than a year away, the clock is ticking for firms to ensure compliance. While the implementation date of 1 January 2026 is top of mind for many, it is essential not to overlook several key milestones in 2025. These will be particularly relevant both for firms seeking SDDT status and banks navigating Basel 3.1 requirements.

On 12 September 2024, the PRA published Consultation Paper 7/24 (The Strong and Simple Framework: The simplified capital regime for Small Domestic Deposit Takers (SDDTs)) as part of its Phase 2 of announcements, which sets out the proposed simplified capital regime for SDDTs.

The Prudential Regulation Authority (PRA) has introduced the Strong and Simple Framework for domestic banks and building societies that are non-systemic. The banks and building societies that meet the eligibility criteria are classified as Small Domestic Deposit Takers (SDDT) firms.

PRA’s Policy Statement PS15/23 (The Strong and Simple Framework: Scope Criteria, Liquidity and Disclosure Requirements) specifies the finalised SDDT criteria and prudential regulations for features (e.g., liquidity) not relating to capital requirements.
