Zenith Joins Japanese Megabank Working Group to Tokenize $1.6 Trillion JGB Repo Market On-chain

Zenith has joined the Progmat-led Tokenized JGB / On-chain Repo Working Group to modernize Japan’s massive ¥250–270 trillion Japanese Government Bond (JGB) repo market. This consortium includes major financial institutions such as MUFG Bank, Mizuho Bank, Sumitomo Mitsui Banking Corporation, and BlackRock Japan. The initiative focuses on tokenizing JGBs and enabling on-chain repo transactions using stablecoin cash legs to achieve T+0 settlement and 24/7 availability. By leveraging Zenith’s Ethereum-compatible execution layer on the Canton Network, the group aims to capture a significant portion of the $1.6 trillion repo market. This development is significant as it marks a major push to bring institutional-grade government bond liquidity onto blockchain infrastructure. The working group, which began in May 2026, plans to release a comprehensive report in October 2026 with pilot issuances expected later this year. This collaboration highlights the growing trend of integrating traditional finance with privacy-enabled, compliant blockchain environments to enhance global capital market efficiency.
