Japan banks push stablecoin

Highlights

MUFG, Mizuho and SMBC plan live stablecoin transactions by March 2027.
The stablecoin would be issued under a trust agreement.
The banks will form a council to address governance and operations.

The banks said they intend to issue the stablecoin under a trust agreement, with all three acting as joint settlors and a trust bank or similar institution serving as trustee. They also plan to create a council to work through governance, operations, and other practical issues before issuance. The banks are targeting commercial stablecoin transactions during fiscal 2026, which runs through March 2027, The Block reports.

From pilot project to banking product

In October, MUFG, Mizuho, and SMBC began examining how several banking groups could jointly issue stablecoins classified as electronic payment instruments under Japanese law. In November, Japan’s Financial Services Agency said it would support the project through its FinTech Proof-of-Concept Hub, with the aim of checking whether such issuance could be carried out lawfully and properly under existing rules.

The structure matters because Japan has taken a more bank-centered approach to stablecoins than many other markets. Amendments to the Payment Services Act, which took effect in June 2023, defined fiat-backed stablecoins as electronic payment instruments and limited issuance and handling to regulated entities such as banks, trust companies, and fund transfer operators.

That legal clarity has helped create room for large financial institutions to move beyond experiments. The megabanks’ project is not aimed at crypto speculation. Its likely use cases are payments, settlement, treasury operations, and cross-border transfers, areas where banks already have clients but where traditional rails can be slow and costly.

Stablecoin momentum grows in Japan

Japan’s stablecoin market has been gaining speed since the regulatory changes. Fintech firm JPYC launched a legally recognized yen stablecoin in 2025, while other groups have been preparing trust-backed yen tokens for institutional and cross-border use. The entry of MUFG, Mizuho, and SMBC would mark a different stage because of their scale and direct role in Japan’s corporate banking system.

A jointly issued stablecoin will need clear rules for redemption, reserve management, compliance checks, transaction monitoring, and responsibility among the participating institutions.

A test for regulated digital money

If Japan’s top banks can run live stablecoin transactions by March 2027, the country could offer one of the clearest examples of regulated stablecoins moving into commercial banking.

The timing also matters internationally. Europe already operates under MiCA, and the United States is still shaping its stablecoin and market-structure rules. Japan, by contrast, has a working legal category for electronic payment instruments and major banks willing to use it.
