MUFG Tests Blockchain-Based JGB Repo Settlement on Canton Network

Mitsubishi UFJ Financial Group (MUFG) is testing whether Japan’s government bond market can move closer to real-time settlement by using blockchain technology, marking another step in the country’s broader effort to modernize financial infrastructure.

MUFG said on Aug. 13 that four companies within its group will work with Digital Asset and Progmat on a proof-of-concept (PoC) for Japanese government bond (JGB) repo transactions using the Canton Network.

The project is designed to examine whether repo transactions involving JGBs can be settled more efficiently while remaining connected to Japan’s existing securities infrastructure. Rather than replacing the current legal framework with fully tokenized securities, MUFG said the JGBs involved in the test will retain their status as book-entry transfer bonds.

The approach could allow traditional securities records and blockchain-based transaction records to operate alongside each other, potentially creating a bridge between Japan’s established financial system and emerging digital asset infrastructure.

MUFG Explores Real-Time JGB Repo Settlement

At the center of the project is the settlement of JGB repurchase agreements, commonly known as repos. These transactions play an important role in financial markets because they allow institutions to obtain short-term funding using securities as collateral.

MUFG’s first PoC will examine delivery-versus-payment settlement involving JGBs and digital money. The objective is to coordinate the transfer of securities and cash so that both sides of a transaction settle together.

This type of synchronization could reduce settlement risk and potentially shorten the time required to complete transactions.

Under the proposed structure, the relevant JGB account register would continue to play a role in recording ownership, while blockchain records would be updated in coordination with those existing records.

Digital Asset will provide the tokenization framework based on the Canton Network, while Progmat will contribute analysis of existing market practices and help with product design.

MUFG Bank and Mitsubishi UFJ Morgan Stanley Securities will participate as market participants. MUFG Bank and Mitsubishi UFJ Trust and Banking will serve as account management institutions, with MUFG Bank also acting as the deposit-taking institution.

MUFG has not disclosed the names of external trading counterparties involved in the test. It also has not announced a date for commercial deployment.

Second PoC Targets Repo Automation

The project includes a second test focused on automating more of the repo transaction lifecycle.

Secured Finance AG will use its lending protocol to examine how smart contracts could automate functions currently handled through conventional processes.

The objective is not simply faster settlement. MUFG is also exploring whether blockchain-based automation can improve operational efficiency and support real-time intraday repo transactions.

Intraday settlement could become increasingly important as financial institutions look for ways to move collateral and liquidity more frequently throughout the trading day.

MUFG said the proposed system could also support longer settlement windows, potentially giving market participants greater flexibility in managing collateral and short-term funding.

The combination of automated processes, digital records and synchronized settlement could eventually reduce some of the manual steps involved in traditional repo markets.

However, the current project remains experimental, and MUFG has not indicated that the technology is ready for full-scale commercial use.

Japan’s Financial Regulators Are Watching the Technology

The JGB repo initiative was selected in February under Japan’s Financial Services Agency Payment Innovation Project.

The program is intended to examine legal, supervisory and compliance issues surrounding new payment and settlement models before they are introduced more broadly.

That regulatory component is particularly important for Japan’s financial sector because government securities remain deeply integrated with established market infrastructure.

MUFG’s announcement does not represent regulatory approval for a commercial blockchain-based JGB repo service. Instead, the PoC gives the participating institutions an opportunity to examine how the technology could function within Japan’s existing legal and operational framework.

The distinction between tokenizing a security and using blockchain technology to coordinate existing securities records is also significant.

MUFG is not saying that JGBs will simply be converted into new digital securities. Instead, the project seeks to connect blockchain-based transaction records with the existing book-entry system while preserving the legal status of the underlying government bonds.

Japan Expands Blockchain Experiments Around Government Bonds

The MUFG initiative comes as several major Japanese financial institutions explore blockchain applications for government securities and collateral markets.

Japan Securities Clearing Corporation, Mizuho, Nomura and Digital Asset have previously tested the use of JGBs as digital collateral on blockchain infrastructure.

Those experiments similarly focused on how government bonds could be used within digital financial markets without abandoning Japan’s existing securities framework.

MUFG is also working on digital money infrastructure that could eventually interact with tokenized financial assets.

MUFG, SMBC and Mizuho plan to conduct live transactions using a jointly issued yen stablecoin by March 2027 under a shared framework.

However, MUFG’s latest JGB repo PoC does not state that the planned joint yen stablecoin will be used for repo settlement.

That distinction is important because the cash component of a future blockchain-based securities market could involve several different forms of digital money, including tokenized bank deposits or stablecoins.

Canton Network Brings Global Repo Experience

MUFG’s experiment also reflects developments outside Japan.

The Canton Network has been used in international experiments involving tokenized collateral, government bonds and digital cash. In January, an industry group announced the completion of cross-border intraday repo transactions involving U.S. Treasuries, European government bonds, dollar and euro cash, and tokenized commercial bank deposits.

MUFG has also pointed to commercial intraday U.S. Treasury repo services as an example of how the technology could eventually be applied to government bond markets.

For Japan, however, the challenge is not simply replicating overseas models.

The country must determine how blockchain settlement can coexist with its existing securities registration, custody, payment and regulatory systems.

That makes interoperability a central issue for MUFG’s experiment.

What Comes Next for MUFG’s JGB Blockchain Project?

MUFG plans to continue discussions with regulators and expand engagement with domestic and international financial institutions as the PoC develops.

The group also expects to work with Morgan Stanley, its strategic alliance partner, as it examines the potential future of digital repo markets.

MUFG has not provided a completion date, production launch target or transaction volume for the project.

The most important question will be whether blockchain-based settlement can synchronize legally recognized JGB ownership with onchain transaction records without creating discrepancies between traditional and digital systems.

If the technology proves workable, Japan could eventually have a pathway toward faster and more automated government bond repo transactions while preserving the legal and institutional foundations of its existing securities market.

For now, MUFG’s Canton Network project remains a proof-of-concept rather than a live 24/7 JGB market. But the experiment highlights how Japan’s largest financial institutions are increasingly exploring blockchain not as a replacement for traditional markets, but as an infrastructure layer that could make those markets faster, more automated and more connected to the emerging digital financial system.
