Mark Your Calendar: Key Dates for Basel 3.1 and SDDT

7 Jan

With the 1 January 2027 Basel 3.1 and SDDT go-live about a year away, many firms are progressing at different speeds. For those still early in their journey, 2026 will be an important year to build momentum and prepare with confidence.

While the 2027 deadline is front of mind, it is equally important to focus on the key milestones that fall in 2026. These include the PRA’s data-collection exercise, which will influence capital requirements, as well as any permissions that need to be sought and notifications to be submitted. To respond effectively, firms will need to carry out full risk-exposure calculations under the revised rules, rather than relying on indicative estimates. This work can be detailed and time-consuming, involving key decisions such as the choice of approaches, supported by appropriate governance, challenge, and sign-off.

To support a smooth transition, firms may find it helpful to start planning early and set out a clear, phased roadmap for 2026. Early preparation will help ensure accurate submissions, timely regulatory engagement, and well-governed decisions. By addressing dependencies around people, data, and systems in advance, firms can position themselves for a confident and well-managed implementation ahead of the 2027 go-live.
