Japan's ¥250 Trillion Government Bond Repo Market Faces On-Chain Revolution as Progmat Begins Live Testing in November

The Digital Asset Co-Creation Consortium, led by Progmat, has released an interim report detailing a framework to tokenize Japanese Government Bonds (JGBs) for on-chain repo transactions. The initiative involves Japan's three megabanks—MUFG, SMBC, and Mizuho—alongside 69 other organizations, including BlackRock Japan. Rather than creating new assets, the design focuses on migrating existing book-entry transfer bonds to distributed ledger technology to streamline settlement and collateral management. The group plans to begin live testing in November 2026 using the Canton Network to simulate repo operations with tokenized deposits and stablecoins. This effort targets the ¥250 trillion domestic repo market, specifically aiming to replace inefficient, manual post-trade processes with a 'just-in-time' liquidity model. By maintaining existing trading channels while moving settlement on-chain, the consortium seeks to lower adoption barriers for institutional investors. This development marks a significant shift in Japan's RWA strategy, moving from retail-focused security tokens toward the modernization of core financial market infrastructure.
