The Monetary Authority of Singapore (MAS) today launched Ubin+, an expanded collaboration with international partners on cross-border foreign exchange (FX) settlement using wholesale central bank digital currency (CBDC). 

Ubin+ will focus on the following:

  • Study business models and governance structures for cross-border foreign exchange (FX) settlement, where atomic settlement, based on digital currencies, can improve efficiencies and reduce settlement risks compared to existing payment and settlement rails.
  • Develop technical standards and infrastructure to support cross-border connectivity, interoperability and atomic settlement of currency transactions across platforms using distributed ledger technology (DLT), and non-DLT based financial market infrastructures.
  • Establish policy guidelines for the connectivity of digital currency infrastructure across borders, for better access and participation. This includes policy relating to governance, access and compliance issues for such linkages.

As part of Ubin+, the following projects will be undertaken with international partners: 

  • Foreign Exchange and Liquidity Management: Project Mariana is a collaborative initiative that explores the exchange and settlement of Swiss franc, Euro and Singapore dollar wholesale CBDCs with an automated market maker (AMM) arrangement. The project is a partnership involving MAS, Banque de France, Swiss National Bank, and the Bank for International Settlements Innovation Hub’s Eurosystem, Switzerland and Singapore Centres.
  • Interoperability between DLT and non-DLT payment systems: MAS is participating in SWIFT’s CBDC Sandbox, together with more than 17 central banks and global commercial banks, to explore cross-border interoperability across digital currencies based on DLT and non-DLT payment systems. 
  • Connectivity across heterogenous digital currency networks: As wholesale digital currencies could potentially gain traction as a cross-border medium of exchange, MAS is studying possible mechanisms to maintain connectivity across CBDC and other heterogenous digital currency networks. MAS will also study the use of smart contracts to optimise efficiency and reduce counterparty risks in the settlement of cross-border transactions.
