Japan’s three lead financial authorities are studying a blockchain-based settlement network for equities and government bonds. A development plan could arrive as early as the start of 2027.
The Financial Services Agency, the Ministry of Finance, and the Bank of Japan plan to form a study group with financial institutions this summer. The group would design the system, according to Nikkei reporting picked up by Cointelegraph and The Block. Its mandate: set the blockchain’s architecture, divide responsibilities among agencies and participating institutions, and chart a roadmap.
The target is settlement speed. Equities currently settle on T+2. Domestic government bonds settle on T+1. The proposed system would compress both to real-time. That shift is the news.
Formal approval would put the system in operation within a few years, with full deployment in the early 2030s. Both Nikkei (via The Block) and Cointelegraph carry that timeline. The sources frame everything conditionally: “could,” “if approved.” No agency has issued a direct statement.
How it would work
The system would convert a portion of the deposits banks hold in Bank of Japan current accounts into digital tokens. Those tokens would circulate on the blockchain for interbank settlement. In practice, this means tokenized reserves would serve as the settlement asset for securities transfers on-chain. Not a separate stablecoin. Not a central bank digital currency.
The project could fall under a multi-year strategic sector investment framework the Japanese government is planning from fiscal 2027, The Block reported.
A broader regulatory backdrop
The settlement study arrives alongside a cluster of blockchain and digital asset policy moves in Japan.
In July 2026, Japan passed amendments to the Financial Instruments and Exchange Act. The changes would reclassify roughly 105 cryptocurrencies as financial instruments, effective during fiscal 2027. They also establish the basis for separate crypto taxation at an effective rate of around 20%, down from a current top rate of up to 55%.
The FSA established a dedicated cryptocurrency and stablecoin division earlier in August 2026. In April, the Japan Securities Clearing Corporation (owned by Japan Exchange Group) launched a trial with Mizuho, Nomura, and Digital Asset. The trial explores using Japanese government bonds as collateral on a blockchain. Three of the country’s largest banks, Mizuho Bank, MUFG, and SMBC, have been running a stablecoin pilot backed by the FSA since November 2025.
Separately, roughly 40 regional and online banks announced a proof-of-concept for interbank transfers using tokenized deposits. Testing could begin as early as this month, per Nada News citing Nikkei.
What is not known
The CoinDesk story on the plan could not be independently accessed for this article. No agency has issued a public statement quoted in the available reporting. All details trace to Nikkei. The study group’s exact start date remains open. So does the specific blockchain technology under evaluation, and whether the plan will ultimately win approval. The conditional language in the sources is doing real work. Nothing here is enacted yet.
