Central banks in the UK, Singapore and Thailand have begun testing synchronized cross-border foreign-exchange settlement that spans traditional RTGS infrastructure and blockchain rails – including stablecoin FX settlement – according to details of the Project Meridian FX APAC pilot published this month. The pilot targets live synchronized settlement by 2028, and it marks the most concrete multi-jurisdiction test yet of replacing correspondent-banking lag with shared ledgers.
How the stablecoin FX settlement pilot works
Project Meridian FX APAC synchronizes the exchange of two currencies across borders so that both legs settle together or not at all – the monetary equivalent of an escrow row that clears in one motion. The design bridges domestic RTGS systems with blockchain and stablecoin rails, removing the herding risk that sits in today’s multiday settlement windows, where one leg can fail and leave the other side holding exposure.
The pilot is deliberately separate from BLOOM, the Singapore-Malaysia-Thailand stablecoin initiative that regional central banks expanded in October. Where BLOOM is about a shared retail-and-payment token, Meridian is about the plumbing of FX itself – the $7.5-trillion-a-day market where efficiency gains are measured in basis points and trapped liquidity.
Why it matters
Cross-border payments remain crypto’s most defensible use case, and regulators increasingly treat it as such. Hong Kong granted its first fiat-referenced stablecoin licenses to a Standard Chartered joint venture and HSBC earlier this year, while Asian corridors already dominate global stablecoin payment volume. A synchronized settlement standard that works across three regulators would give banks a template – and stablecoin issuers a genuinely institutional demand driver that doesn’t depend on speculation.
It also answers the industry’s oldest pitch problem: stablecoins are usually introduced as money you can speculate with, but the regional central-bank track keeps making the quieter case for stablecoins as infrastructure.
From pilot to production
Live synchronized operation is targeted for 2028 – a schedule that acknowledges reality: RTGS upgrades, legal finality, and cross-border oversight agreements don’t ship on crypto timelines. But pilots are where standards get born. If Meridian’s model survives production testing, the winners won’t be token tickers – they’ll be the settlement rails the next decade of finance runs on. Slow is smooth, smooth is fast, and central banks have never been accused of rushing.
