Project Meridian, the first experiment conducted by the BIS Innovation Hub London Centre, has been concluded by the Bank for International Settlements (BIS) and the Bank of England. The project explores the concept of synchronisation, where transactions settle using central bank money in a real-time gross settlement (RTGS) system. This synchronisation is achieved through a new entity called the synchronisation operator, which uses distributed ledger technology (DLT) to connect the central bank’s settlement system with other financial market infrastructures and ledgers. The goal is to reduce transaction costs and risks while increasing efficiency. The Meridian prototype demonstrates how synchronised settlement in central bank money can be applied to different asset classes, such as housing transactions, and offers a standard way for synchronisation operators to connect multiple types of asset ledgers to an RTGS system. The project’s insights will contribute to the analysis of synchronisation’s benefits and shape the design of future settlement systems.
