A statement made on Thursday announced that the Swiss National Bank and the Banque De France will look into the feasibility of a cross-national arrangement of two wholesale central bank digital currencies (CBDCs) on blockchain. The SNB has enlisted a private sector consortium (including R3, UBS, and Credit Suisse) which will be led by Accenture.

The two central banks will use a delivery-versus-payment mechanism to exchange a financial instrument against a euro wholesale CBDC and a euro wholesale CBDC against a Swiss franc wholesale CBDC. The arrangement will be settled between the Banque De France and the Swiss National Bank.

The move represents an expansion of Project Helvetia, an experiment between the Swiss National Bank, the Bank of International Settlements Innovation Hub Swiss Centre, and financial market infrastructure operator SIX. The project, which concluded in December, demonstrated the potential of integrating central bank money with tokenised assets.
