Mitsubishi UFJ, Sumitomo Mitsui, and Mizuho plan to jointly issue a fiat-backed stablecoin by fiscal year 2026, according to Nikkei. The three megabanks will establish a consortium to drive commercialisation, building on a pilot conducted in coordination with Japan's Financial Services Agency.
Why it matters
This is the first coordinated move of its kind from Japan's "big three" banks on a digital asset product. Each institution has explored blockchain rails independently — MUFG's Progmat, SMBC's experiments with tokenised deposits, Mizuho's settlement work — but none has committed to a shared issuance layer until now. A consortium structure lets the banks split the regulatory and operational load while standardising on a single yen-pegged instrument rather than fragmenting the market with competing tokens.
Market impact
The FSA's involvement during the pilot phase signals a faster regulatory path than the wait-and-see posture Tokyo took on earlier private-sector stablecoin efforts. If the consortium ships on FY2026, it positions Japan as the first G7 market with a bank-issued, regulator-coordinated fiat stablecoin at scale — a template other Asian regulators are watching closely. Watch for the consortium charter, the choice of issuer bank, and the first named settlement counterparties.
