Key Takeaways

Japan’s three largest banks are building a shared stablecoin for corporate payments, targeting launch by March 2026.
The stablecoin runs on the Progmat blockchain platform and is legally structured under Japan’s Payment Services Act.
Mitsubishi Corporation is already testing it for cross-border payments between subsidiaries.
Analysts project bank-backed stablecoins could reach $2.8 trillion in global circulation by 2028.

Mitsubishi UFJ Financial Group, Mizuho Financial Group, and Sumitomo Mitsui Financial Group launched a joint proof-of-concept in November 2025 under the oversight of Japan’s Financial Services Agency. The target is a full commercial rollout by March 2026. A second round of testing brought in Nomura and Daiwa Securities in February 2026 to explore stablecoin use in securities and fund settlements.

How It Works

The stablecoin is built on Progmat Coin, a blockchain-based tokenization network developed by Progmat Inc., a fintech firm with roots in MUFG. Legally, the instrument is classified as an “Electronic Payment Instrument” under Japan’s Payment Services Act, with MUFG Trust acting as the primary issuer through a trust bank model. The initial version is pegged to the Japanese yen; a dollar-denominated variant is planned.

One of the framework’s more notable technical decisions is its integration with SWIFT messaging. Rather than forcing corporate clients to abandon existing workflows, the system lets them trigger blockchain-based settlements through the same banking infrastructure they already use.

Early Adoption and Market Reach

Mitsubishi Corporation is the first named user, currently testing the stablecoin for internal transfers between its overseas subsidiaries. The appeal is straightforward: reduce fees and processing delays that still plague correspondent banking. The three banks behind the project collectively serve more than 300,000 major corporate clients — a ready-made distribution network that most new financial products could only dream of.

Taking Aim at USDT and USDC

The broader ambition is to enable 24/7 real-time settlement at meaningfully lower cost than the current system. That puts the initiative in direct competition with established global stablecoins such as Tether (USDT) and Circle’s USDC, at least within Japan’s regulated market.

The Bigger Picture

The timing reflects a wider institutional shift. Analysts suggest that as trust in bank-backed digital currencies grows, global circulation of such instruments could climb toward $2.8 trillion by 2028. Japan’s megabanks, it seems, are not content to watch that market develop elsewhere.
