  • BoE publishes terms of participation for new Synchronisation Lab to launch in spring 2026

    16 October 2025
    The Bank of England (BoE) has published the terms of participation for its upcoming Synchronisation Lab which will support the testing and refinement of a proposed synchronisation capability for the UK's renewed Real-Time Gross Settlement (RTGS) service, RT2. Synchronisation would allow for atomic settlement in central bank money: the conditional settlement of funds in RT2 against assets on a variety of external asset ledgers, meaning that funds in RT2 will settle if and only if the external asset also settles. The Lab is being launched as a platform to simulate the synchronisation interface enabling prospective synchronisation operators (Lab Participants), to develop and demonstrate viable propositions across multiple use cases.

    The Lab is scheduled to launch in Spring 2026 and will run for approximately six months across four six-week testing and development phases. In each phase, Lab Participants will showcase end-to-end synchronised transaction flows and interact with synchronisation users. Lab findings will inform the design and delivery of a potential future live RT2 synchronisation capability. Participation is by invitation by the BoE and based on an application process. Technical onboarding will begin roughly one month before launch. Demonstrations and a final report summarising key learnings will follow the Lab's conclusion.
