The Bank for International Settlements (BIS) together with the Bank of England (BoE), Bank of France, Bank of Italy, Deutsche Bundesbank and the European Central Bank (ECB) has announced the successful demonstration of Project Meridian FX, which explored the interoperability of wholesale payment infrastructures for foreign exchange transactions using new technologies. The project employed distributed ledger technology to synchronise the settlement of FX transactions by ensuring that one leg of a transaction is executed only when its corresponding leg occurs, thereby addressing settlement, liquidity and credit risk. Developed in alignment with the objectives set out in the Group of 20 cross-border payments roadmap, the initiative integrated a synthetic version of the UK real-time gross settlement (RTGS) system with experimental interoperability solutions from the Bank of France, the Bank of Italy and Deutsche Bundesbank (DL3S, TIPS Hash-Link and the Trigger Solution respectively). The outcomes show that the synchronisation mechanism is both asset- and technology-agnostic, underscoring its potential application across various financial market operations.
