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.
