Three of the world's most consequential central banking institutions have taken a significant step toward reimagining the plumbing of global foreign exchange markets. The Bank of England, the Monetary Authority of Singapore (MAS), and the Bank of Thailand have jointly published the results of Project Meridian FX APAC, a cross-jurisdictional experiment that stress-tested foreign exchange settlement across both legacy and next-generation infrastructure. The findings land at a moment when the global financial community is under sustained pressure to reduce the friction, risk, and latency embedded in cross-border currency transactions — and when the debate over whether distributed ledger technology can play a credible institutional role has never been more pointed.
What the Project Set Out to Prove
Project Meridian FX APAC was designed around a deceptively straightforward question: can foreign exchange settlement operate reliably and securely when the underlying infrastructure on each side of a transaction is fundamentally different? To answer it, the three central banks constructed a testing environment that deliberately spanned two distinct settlement paradigms. The first was the traditional Real-Time Gross Settlement (RTGS) system — the backbone of central bank money movement in virtually every major economy, characterised by finality, central control, and deep institutional trust built over decades. The second was a Distributed Ledger Technology (DLT)-based system, representing the emerging class of programmable settlement infrastructure that has attracted increasing interest from monetary authorities, commercial banks, and multilateral bodies alike.
The choice of counterparts was itself deliberate and strategically loaded. The Bank of England represents one of the oldest and most systemically significant central banks on earth, currently in the midst of a multi-year renewal of its own RTGS infrastructure. The MAS has positioned Singapore as a global laboratory for financial innovation, running a series of ambitious tokenisation and payments experiments under its Project Guardian and broader fintech policy agenda. The Bank of Thailand, meanwhile, represents a rapidly digitising emerging economy with a strong domestic payments infrastructure and growing cross-border payment volumes tied to regional trade corridors. Bringing these three institutions into a single experimental framework is no small feat of regulatory diplomacy.
The Interoperability Challenge at the Core
The central technical and policy challenge that Project Meridian FX APAC addressed is one that has long frustrated international settlements practitioners: the interoperability gap. When one counterparty to an FX transaction holds central bank money in a conventional RTGS environment and the other operates within a DLT-based settlement system, the mechanics of achieving simultaneous, final, and irrevocable payment-versus-payment — the so-called PvP settlement standard that eliminates principal risk — become considerably more complex. Legacy systems were not designed with programmable ledgers in mind, and DLT systems have historically operated in isolated pilots disconnected from the core money infrastructure that gives settlements their legal and financial weight.
What the Meridian framework — originally developed by the Bank of England — has sought to demonstrate is that a synchronisation layer can be constructed to bridge these two worlds without requiring either side to abandon its existing infrastructure. This is a critical design philosophy. Rather than demanding that central banks or commercial institutions migrate wholesale onto a single new platform, the approach treats interoperability as an engineering and governance problem to be solved at the connection point, preserving institutional sovereignty over domestic infrastructure while enabling cross-border atomicity. The APAC extension of this work brings that philosophy into contact with the real-world complexity of multi-currency, multi-time-zone, multi-regulatory-jurisdiction settlement — precisely the conditions under which FX markets actually operate.
Why This Collaboration Matters for the Region and Beyond
The Asia-Pacific dimension of this project is not incidental. The region accounts for a substantial and growing share of global FX turnover, with currency pairs involving the Singapore dollar, Thai baht, and a constellation of regional currencies representing significant daily volumes. Settlement failures, correspondent banking delays, and the persistent inefficiencies of the existing correspondent network impose real costs on businesses, financial institutions, and ultimately on the trade flows that underpin regional growth. Any infrastructure that credibly reduces settlement risk and shortens settlement cycles across these corridors carries measurable economic value.
The involvement of a major Western central bank — the Bank of England — alongside two Asian monetary authorities also signals something important about the architecture of future cross-border payment cooperation. Rather than fragmenting into rival regional blocs of incompatible digital currency or settlement infrastructure, Project Meridian FX APAC embodies a philosophy of open, standards-based interoperability that could serve as a template for broader multilateral engagement. The Bank for International Settlements (BIS) Innovation Hub has been pursuing related work through its own cross-border payment projects, and the Meridian results will inevitably feed into those wider deliberations about what a future global settlement architecture should look like.
What This Means for the Industry
For commercial banks, payment service providers, and corporate treasuries, the significance of Project Meridian FX APAC lies less in its immediate operational implications — this remains a central bank research and experimentation exercise — and more in the direction it signals. When three central banks from jurisdictions as geographically and architecturally diverse as the United Kingdom, Singapore, and Thailand commit institutional resources to testing DLT-based settlement interoperability alongside RTGS, they are sending a clear message to the market: the question is no longer whether distributed ledger infrastructure will play a role in future wholesale payment systems, but how that role will be governed, standardised, and integrated with the monetary frameworks that underpin financial stability. For technology providers, incumbent banks, and fintech challengers building in this space, that shift in posture from central banks constitutes a substantial de-risking of the innovation thesis. The results of Project Meridian FX APAC will be studied closely — and they should be.
