Japan’s Three Megabanks to Issue Yen Stablecoin by March 2027, Reshaping Settlement

Japan’s three megabanks, MUFG Bank, Sumitomo Mitsui Banking Corporation and Mizuho Bank, will jointly issue a stablecoin linked to the value of the yen. The target is by the end of March 2027, the close of Japan’s fiscal 2026. If a bank-issued token backed by legal-tender settlement rails becomes operational, part of Japan’s corporate payment and digital-asset pricing infrastructure could move away from an almost entirely dollar-centered stablecoin market.

Shift in yen payment infrastructure

The core design is a bank-issued digital currency that tracks 1 yen per coin. Dollar-linked tokens dominate the current stablecoin market, while yen-based products have remained limited in use and trust. A joint model reduces compatibility problems that would arise if each bank issued a separate token. It also allows corporate clients to use the same payment instrument across banking relationships. Japan already has a regulatory framework that treats stablecoins as electronic payment instruments and assigns issuance responsibility to approved entities.

Impact for Korea

The first effects are likely to appear in FX and trade settlement. At about 940 won per 100 yen, a 1 million yen payment equals roughly 9.4 million won, and 1 billion yen is about 9.4 billion won. If more companies settle Japanese import and export payments in yen stablecoins, waiting times, intermediary bank fees and confirmation processes could shrink. Korean companies gain another settlement option with Japanese partners, but pressure will also rise to clarify won-based digital payment rules. User protection, reserve asset management, anti-money-laundering controls and FX reporting remain the key Korean issues.

Outlook and risks

In the near term, yen stablecoins are more likely to be used for corporate settlement and tokenized assets than as retail investment products. Bank issuance strengthens credibility, but reserve transparency, system outages, delayed redemption and cross-border transfer rules must be tested. Holding a yen token still creates FX risk when the won-yen rate moves sharply.
