MUFG Launches Proof-of-Concept for On-Chain Japanese Government Bond Repo Transactions

Mitsubishi UFJ Financial Group (MUFG), through its subsidiaries MUFG Bank, Mitsubishi UFJ Morgan Stanley Securities, and Mitsubishi UFJ Trust and Banking, has launched a proof-of-concept (PoC) to bring Japanese Government Bond repurchase transactions on-chain. The initiative is being conducted in collaboration with blockchain infrastructure providers Digital Asset Holdings, Progmat, and Secured Finance.

The pilot project forms part of a broader set of pilot initiatives selected under the Financial Services Agency (FSA) of Japan’s “Payment Innovation Project”.

Strategic Rationale & Industry Context

While blockchain applications in Japan have primarily targeted the primary issuance market—such as security tokens backed by bonds and real estate—international markets are shifting focus to secondary-market transactions. Institutions in Europe and the United States have increasingly tested and deployed on-chain government bond repo systems to enable real-time, 24/7 intraday settlement, improving operational, funding, and capital efficiency.
Given the high liquidity and creditworthiness of JGBs in global collateral management, MUFG aims to test similar operational capabilities in Japan.

Scope and Technology Architecture

The PoC will evaluate two primary operational frameworks:

1. Delivery-versus-Payment (DvP) Settlement: Testing simultaneous settlement of JGBs and digital money (including tokenized deposits or stablecoins) on-chain while maintaining the existing legal structure of JGBs as book-entry transfer bonds.
   
2. Automated Lifecycle Management: Utilizing smart-contract lending protocols provided by Switzerland-based Secured Finance AG to automate the execution, collateral management, and lifecycle of repo agreements.

Key Partner Roles

• Digital Asset (DA): Providing the tokenization framework built on the institutional-focused Canton Network.
• Progmat: Assisting in productization and the application of blockchain technology to legal JGB book-entry transfer registers.
• Secured Finance AG (SF): Facilitating the lending protocol infrastructure to automate fixed-rate, order-book, and collateralized execution on-chain.

MUFG indicated it plans to consult with financial regulators, domestic and international market participants, and strategic partner Morgan Stanley as it evaluates potential future social implementation.
