BoE advances synchronisation design

Highlights

The Bank of England convened the first refreshed synchronisation thematic engagement working group to gather industry feedback for designing a live synchronisation service, including RT2 and Synchronisation Lab testing.
Key design areas requiring further synchronisation operator input include settlement models, earmark lifecycles, transaction timing, contingency planning, and synchronisation flows, with divergence between operators and account holders on liquidity management.
Timelines for implementation and regulatory updates remain under development, with clarification on legal, contractual, and rulebook arrangements expected in a paper and further details likely early next year.

Industry input shapes service design

As reported by the Bank of England, the first synchronisation thematic engagement working group since the terms of reference were refreshed sets out the group’s purpose, structure and role in supporting the design of a live synchronisation service. The central bank says the forum is intended to collect focused feedback from industry participants and build on earlier experimentation and policy work.

The Bank gives members an overview of synchronisation, including the functions of RT2, synchronisation operators and ecosystem readiness, and highlights the launch of the Synchronisation Lab for hands-on testing. It also says work is continuing in parallel on policy and design issues such as risk mitigation, regulation, cost recovery and onboarding processes.

The Bank reiterates that group members must comply with competition law and treat shared information as confidential, while making clear that the group does not make final design decisions. It also sets out the structure of future meetings and the use of questionnaires and thematic discussions to collect feedback.

Regulatory and operational questions remain open

The Bank identifies key areas for synchronisation operator input, including settlement design models, earmark lifecycle, transaction timing, contingency planning and synchronisation flows. It also highlights account holder issues such as earmarking, transaction prioritisation and account controls, noting that the views of synchronisation operators and account holders may differ, particularly on earmark lifecycle and liquidity management.

Attendees raise questions about cancellation and timeout functions within the earmark lifecycle, governance of settlement models, rule books, legal frameworks and the respective roles of synchronisation operators and account holders. The Bank says these topics will be examined in more detail in the upcoming meeting series, with slides and minutes shared to keep participants informed.

When asked about go or no-go decision points and implementation timing, the Bank says timelines are still being developed and further details will be shared when available. It also plans to provide an update on the regulatory status and direction of travel for synchronisation operators when more information is available, likely early next year, and to prepare a paper clarifying legal, contractual and rulebook arrangements between the Bank, synchronisation operators and account holders.

Our earlier article on U.S. security concerns over China-made printed circuit boards (PCBs) in AI and defense supply chains explained how dependence on these components has intensified calls to harden procurement for military and other critical-use systems. We also noted that rising AI hardware demand is boosting U.S. manufacturers even as costs increase, while policymakers weigh subsidies and requirements to reduce strategic risk.
