Japanese Banking Giants Target March 2027 for Joint Yen Stablecoin Launch

Japan's leading financial institutions, Mitsubishi UFJ Financial Group (MUFG), Sumitomo Mitsui Financial Group (SMBC), and Mizuho Financial Group, have taken a significant step towards jointly issuing a stablecoin by the end of fiscal year 2026, which concludes in March 2027. This strategic move aims to enhance the adoption of digital assets within the Japanese financial system, particularly by maximizing efficiency and speed in corporate payments.

The banking units of the three megabanks will establish a dedicated council to examine the stablecoin's operational structure, technical infrastructure, and regulatory compliance. The stablecoin will be issued under a trust agreement, with the banks acting as joint settlors and a trust bank or similar institution serving as the trustee. This framework will allow the banks to share a single issuance structure instead of developing separate tokens.

Japan's Financial Services Agency (FSA) has been actively supporting the pilot phases of this initiative since November 2025, encouraging the banks to collaborate on a common standard rather than pursuing individual, competing stablecoins. Japan enacted legislation in 2022 that defines stablecoins as a form of digital money and restricts their issuance to licensed banks and trust companies.

This development holds the potential to boost yen-denominated digital transactions in a global stablecoin market currently dominated by US dollar-pegged tokens. The technical foundation for the project will be provided by the Progmat platform, which MUFG developed in collaboration with NTT Data and other local banks. Progmat supports various public blockchains, including Ethereum, Polygon, Avalanche, and Cosmos, enabling seamless movement of tokens across different networks.

Initially focusing on business-to-business (B2B) and intra-group payments rather than the retail market, this stablecoin is designed for large corporate structures. Mitsubishi Corporation, a sister company of MUFG, has signed on as one of the first pilot partners, testing international intra-group transfers across its more than 200 subsidiaries. The initiative aims to offer faster, cheaper, and more transparent solutions for cross-border payments, potentially replacing costly legacy systems like the SWIFT network and the domestic Zengin system.

Analysts suggest that the success of this joint stablecoin initiative by the three major banks could significantly strengthen Japan's position in global digital payment systems. With the support of the FSA, this bank-led stablecoin is expected to evolve beyond a mere experiment to become a crucial component of the country's financial infrastructure. The project targets an aggregate transaction volume of one trillion yen (approximately $6.5 billion) by 2028.
