Japan's central bank is advocating for a comprehensive approach to designing the future global currency system, according to Foresight News. Vice Governor Ryozo Himino emphasized at the Japan Society of Monetary Economics annual meeting that the options should not be limited to central bank digital currencies (CBDCs) and stablecoins. He suggested that tokenized bank deposits and blockchain-based central bank reserves should also be considered.

Himino noted that the United States has banned the issuance of CBDCs, opting instead to promote stablecoins to strengthen the dollar's status as a global reserve currency. Meanwhile, Europe is advancing the digital euro to address regional fragmentation in the retail payment system. These differing approaches highlight the need for a currency system design that considers technological feasibility, social costs, user convenience, financial stability, and monetary policy.

Japan is preparing for both paths, having introduced stablecoin legislation and advancing a CBDC pilot project. The Bank of Japan has launched a 'sandbox project' to explore the technical feasibility of tokenizing central bank reserves for blockchain payment settlements. Analysts suggest that incorporating blockchain technology into reserve settlements could enable real-time clearing around the clock and reduce settlement congestion risks during stress scenarios.
