MUFG Launches Blockchain Proof-of-Concept for Real-Time Japanese Government Bond Repo Settlement #
Japan’s largest banking group is moving to address the country’s slow government bond repo settlement cycle with a proof-of-concept that would put Japanese Government Bond (JGB) transactions on a distributed ledger.
Mitsubishi UFJ Financial Group (MUFG) said on August 13 that four of its entities (MUFG itself, MUFG Bank, Mitsubishi UFJ Morgan Stanley Securities, and Mitsubishi UFJ Trust and Banking) will work with blockchain infrastructure developer Digital Asset and Japanese blockchain firm Progmat to run the proof-of-concept on the Canton Network, a distributed ledger built for regulated financial institutions.
The pilot targets a longstanding inefficiency in fixed-income markets. Under current arrangements, JGB repo settlements typically take one to three business days to complete. MUFG’s proof-of-concept aims to cut that to real-time, 24/7 atomic settlement, in which both legs of a repo transaction would settle simultaneously on-chain. The project would also automate the full lifecycle of repurchase transactions and improve funding and capital efficiency for participants, according to the company’s announcement.
The Canton Network includes privacy controls that let institutions share only the data relevant to each counterparty, a feature that wholesale fixed-income markets require for confidentiality. Secured Finance AG, a Switzerland-based lending protocol provider, is also participating to support the repo transaction workflow.
JGBs are among the most heavily traded securities in Asia, with deep liquidity and high credit quality. MUFG expects the proof-of-concept to conclude by end of 2026, with a potential commercial rollout targeted for fiscal years 2027 through 2029.
The pilot runs under the Payment Innovation Project, a sandbox programme Japan’s Financial Services Agency launched in February 2026 to allow firms to test advanced payment technologies including blockchain settlement, stablecoins, and tokenization in a regulated environment.
MUFG joins other global institutions that have already explored on-chain repo. JPMorgan’s Kinexys network has processed blockchain-based intraday repos on US Treasuries since 2020, and European banks have run similar proof-of-concept programmes. MUFG acknowledged that overseas markets have moved ahead in this area, describing the proof-of-concept as an effort to close the gap for Japan’s domestic bond market.
