Bank of England, Singapore and Thailand Test Blockchain FX Settlement

Central banks from three jurisdictions have demonstrated a way to settle cross-border foreign exchange transactions more safely, without forcing every institution onto the same technology stack. The Bank of England announced the results of Project Meridian FX APAC on Friday, working with its counterparts at the Monetary Authority of Singapore and the Bank of Thailand.

The core of the experiment is payment-versus-payment settlement, known as PvP. It guarantees that one currency moves only when the corresponding payment in the other currency also settles. That single mechanism attacks one of the oldest problems in FX: the risk that one side of a trade pays out while the counterparty fails to deliver.

The project went further than basic PvP. It also tested multilateral netting, a technique that lets banks offset payment obligations against one another rather than settling every transaction one by one. The practical effect is lower liquidity requirements. Banks tie up less capital in pre-funded settlement accounts, which is a direct operational cost saving, not a trading story.

What did the experiment actually prove?

The demonstration showed that transactions can be coordinated across conventional settlement systems and blockchain-based systems at the same time. Institutions did not need identical infrastructure to participate. That finding matters because the biggest obstacle to synchronized settlement has always been adoption — no bank wants to rebuild its settlement rails to match everyone else's.

Tom Mutton, the Bank of England's executive director of payments, innovation and fintech, said the project delivered concrete results. "Project Meridian FX APAC provides practical evidence of how synchronised settlement could help reduce risk and improve efficiency in cross-border FX transactions," Mutton said in the announcement.

The context is competitive pressure. Stablecoins are increasingly offering an alternative to conventional cross-border payments, with faster transfers and round-the-clock availability that legacy correspondent banking cannot match. Central banks have a reason to show that regulated infrastructure can be modernized rather than bypassed entirely.

What happens next, and when?

The Bank of England plans to introduce a live synchronisation interface in 2028. That is the concrete deadline the project points toward, and it is not a launch date for a full commercial system.

Three gaps remain before deployment:

• Legal arrangements. Synchronized settlement across borders raises questions about finality and which jurisdiction's rules govern a failed transaction.
• Regulatory oversight. Coordinating systems across the UK, Singapore and Thailand requires supervisory frameworks that do not yet exist in final form.
• Broader participation. A pilot with three central banks proves the concept; a production network needs commercial banks and market infrastructures to join.

So what does this change for banks and payment providers right now? In operational terms, not much yet — no commercial system is live, and no institution can plug into Meridian today. What it changes is the roadmap. Banks planning settlement architecture over the next several years now have central-bank-backed evidence that hybrid coordination between traditional and blockchain systems works in practice, and a 2028 target against which to budget their own integration timelines.
