Bank of Japan to Test Blockchain-Based Reserve Settlement System

Published

on

🚨

The Bank of Japan is moving to place central bank reserve money onto blockchain infrastructure, a step that marks the first G7 central bank validation of distributed ledger technology at the reserve settlement level.

BOJ Governor Kazuo Ueda confirmed the initiative Tuesday in a speech at the FIN/SUM conference in Tokyo, framing it as a necessary adaptation to what he called a “new financial ecosystem.”

The announcement carries institutional weight beyond Japan’s borders. It arrives as central banks globally race to establish credible blockchain settlement frameworks before private-sector tokenization outpaces regulatory infrastructure.

Key Takeaways:

  • The BOJ is launching a sandbox to test whether central bank current account deposits — institutional reserves — can operate on blockchain-based systems, targeting interbank and securities settlement.
  • Japan is an active participant in Project Agora, the BIS-led multilateral experiment exploring tokenized central bank money for cross-border wholesale settlement.
  • Governor Ueda explicitly flagged smart contract code errors as a direct threat to financial stability, signaling the BOJ views technical risk validation as a precondition for any production deployment.

What the Bank of Japan Sandbox Is Actually Testing

The sandbox targets BOJ current account deposits, the reserves commercial banks hold at the central bank, as the asset to be tokenized and tested on blockchain rails.

Ueda specified two primary use cases: domestic interbank settlement and securities settlement, both currently processed through BOJ-NET, Japan’s national financial network.

The core technical challenge is interoperability. The BOJ is not looking to replace legacy infrastructure wholesale but to prove blockchain can connect with it. Smart contract functionality sits at the center of that value proposition, enabling faster, programmable execution of settlement instructions that currently require manual or batch processing.

Ueda did not specify a blockchain architecture or timeline for sandbox completion. He confirmed the BOJ will engage external experts throughout development, suggesting technology firm or academic partnerships are forthcoming.

However, Ueda’s concerns about smart contract risk were unambiguous:

“Smart contracts are highly convenient in that they allow transactions to be carried out automatically without any manual labor. When the design of the smart contracts is inadequate, however, there is a risk that the stability of financial markets and payment systems will be threatened due to fraudulent use.”

What Does the BOJ Move Signal for Tokenized Finance?

Japan’s experiment positions it alongside, not behind, the most advanced institutional blockchain programs globally.

The BOJ is a participating jurisdiction in Project Agora, the Bank for International Settlements initiative exploring tokenized central bank money for cross-border wholesale payments.

Ueda confirmed that Project Agora participants are actively designing a framework for central banks to issue tokenized deposits on-chain with embedded smart contract functionality.

That multilateral dimension matters. Cross-border settlement inefficiencies cost the global financial system billions annually in correspondent banking delays and FX conversion friction.

A BIS-coordinated framework with BOJ participation opens a path toward atomic settlement across currencies, without relying on private stablecoin infrastructure.

The domestic context reinforces the institutional momentum. Japan’s Financial Services Agency ran consultations in 2025 on reclassifying cryptocurrencies on par with securities.

In effect, the government has embedded blockchain and tokenization in its economic growth strategy. Japan’s first yen-pegged stablecoin, JPYC, launched in January 2021. The BOJ sandbox does not emerge from a vacuum; it sits atop an accelerating national tokenization agenda.

Crypto Ecosystem Exposure Remains Indirect but Real

Permissioned blockchain networks, purpose-built for institutional settlement, the architecture most likely to underpin BOJ experiments, require the same smart contract tooling and security standards that public chains have been developing for years.

So, protocols and networks exposed to tokenized real-world assets and institutional-grade settlement infrastructure stand to benefit most as central bank experiments validate the underlying technology. The question is timing and whether public or permissioned chains capture the institutional layer first.

The BOJ’s next visible milestone will be the publication of technical findings from the sandbox and the naming of external expert partners.

Those announcements will undoubtedly reveal which blockchain architecture Japan’s central bank considers fit for reserve infrastructure, and that choice will carry weight across the institutional DeFi space.

Visa and Stripe’s Bridge Expand Global Stablecoin Card Program

Visa and Stripe's Bridge Expand Global Stablecoin Card Program

Global payment giant Visa is expanding its stablecoin card partnership with Stripe-owned Bridge, expanding the rollout of stablecoin-linked Visa cards worldwide and testing onchain settlement.

Visa and Bridge are expanding their joint card program to 18 countries, with plans to reach more than 100 across Europe, Asia-Pacific, Africa and the Middle East by the end of the year, according to a Tuesday announcement.

The expansion follows the program’s initial launch in April 2025, which first supported markets in Latin America, including Argentina, Colombia, Ecuador, Mexico, Peru and Chile.

In addition to the expansion, the companies are testing stablecoin settlement through Visa’s pilot program, enabling issuers and acquirers to settle transactions using stablecoins rather than fiat.

The move highlights the ongoing stablecoin race in the payments industry, with Mastercard recently enabling stablecoin card spending in the US via the self-custodial crypto wallet MetaMask.

Onchain support enabled through Bridge’s partnership with Lead Bank

When the card program launched in 2025, transactions were processed by Bridge, deducting funds from the customer’s stablecoin balance and converting them into fiat, allowing merchants to receive payment in local currency like any other card transaction.

Under the new collaboration, enabled by independent commercial bank Lead Bank, settlement is now set to occur directly in stablecoins.

“Now, through Bridge’s partnership with Lead Bank, these card transactions can be settled onchain with Visa,” the announcement noted.

“Visa is committed to meeting businesses where they operate, and increasingly, that’s onchain,” Visa’s head of crypto, Cuy Sheffield said. “Expanding our work with Bridge gives us one more way to bring the speed, transparency and programmability of stablecoins directly into the settlement process,” he added.

Additionally, Visa is evaluating potential support for Bridge-issued assets, or stablecoins created and managed using Bridge’s infrastructure platform. Unlike major stablecoins such as Tether’s USDt (USDT) or Circle’s USDC (USDC), Bridge-issued stablecoins are created programmatically by businesses rather than a third-party issuer.

“This expansion of our work with Visa will enable businesses launching their own custom stablecoins to use them seamlessly within their card programs,” Bridge co-founder and CEO Zach Abrams said.
