Bank of Japan Deputy Governor Ryozo Himino is calling for a unified approach to digital money. Speaking at the Japan Society of Monetary Economics on May 16, Himino proposed a framework that treats central bank money, bank deposits, stablecoins, and tokenized deposits as part of a single interconnected system.
Himino warned that without coordination, the rise of private digital currencies could fracture the monetary system into incompatible silos. His core principle, the 'singleness of money,' insists that every form of currency must be interchangeable at face value without friction.
Japan already has a regulatory framework requiring stablecoins to be fully backed by fiat currency and is piloting a digital yen. Himino's vision suggests the Bank of Japan is not seeking to ban private digital money, but insists on full convertibility with central bank money.
For the stablecoin industry, this signals a favorable regulatory environment for compliant issuers, but a high bar for those with opaque reserves. Tokenized deposits are given a green light with clear guardrails.
