Japan’s government and central bank appear to be moving toward a study of blockchain-based settlement that could handle stocks and government bonds around the clock. Nikkei reported on Aug. 26 that the Financial Services Agency, the Ministry of Finance, and the Bank of Japan, along with participating financial institutions, plan to set up a study group during summer 2026. The group would aim to complete an initial development plan by early 2027.
As of Wednesday, none of the three government institutions had published a formal announcement confirming the reported study group. So the timeline still comes from the news report, not from an official statement. Still, the direction is clear enough: Japan wants to see whether distributed ledger technology can replace parts of its current settlement system.
Why settle faster
Japanese stock trades currently settle on a T+2 basis, meaning cash changes hands two business days after the trade. Japanese government bonds usually settle on the next business day. A blockchain-based system could tie the transfer of securities more closely to the payment, letting investors get their sale proceeds sooner and perhaps reinvest the money without waiting.
The planned development work is expected to cover the blockchain architecture, how public and private groups would divide responsibilities, and a timetable for rolling the system out. International remittances could be another use case down the road. Nikkei says the infrastructure could become operational in the early 2030s, but that is only if the plan receives formal approval. No final decision on implementation has been announced.
Real-time settlement has a trade-off. It reduces the time counterparties are exposed to each other, but it also shortens the window for lining up cash or securities. That could create new liquidity and operational demands for banks and market participants. The study group will have to weigh those practical issues carefully.
BOJ’s blockchain experiments
The reported effort builds on work the Bank of Japan already has underway. In March, Governor Kazuo Ueda said the central bank was testing settlements using commercial banks’ current account deposits on blockchain. That sandbox project is looking at how blockchain networks could connect with existing systems, with potential uses including domestic interbank transfers and securities settlement.
BOJ Executive Director Kazushige Kamiyama later described the work as an examination of tokenized central-bank account deposits, sometimes called wholesale central bank digital currency. The design could support delivery-versus-payment settlement, where securities and cash move at the same time. This is separate from Japan’s retail digital-yen pilot. The BOJ continues technical research on a retail CBDC, but the government has not decided whether to issue one.
Private tokenized securities already exist
Japan’s private sector hasn’t waited for the government. Progmat recently moved about ¥452 billion in managed tokenized securities onto a dedicated Avalanche network. SBI Holdings and Startale are building Strium, a blockchain meant for round-the-clock tokenized securities trading, with a public test network planned for 2026.
Those private systems show that tokenized assets can be issued and transferred. The government proposal is broader because it could touch the infrastructure behind mainstream Japanese stocks, government debt, and central-bank money. Separately, Japan’s three largest banks are working on a shared yen stablecoin framework, targeting live transactions by March 2027.
What needs to be decided
The study group will need to determine whether Japan should create a new blockchain, connect several regulated networks, or link distributed ledgers with existing market systems. It also has to address governance, cybersecurity, transaction privacy, operational resilience, and how to reverse erroneous or unauthorized transfers. Around-the-clock operation means financial institutions and regulators would need to provide support beyond current market hours.
The next confirmed milestone would be an official announcement naming the participants and the study group’s mandate. The early-2027 development plan should then clarify architecture, funding, testing stages, and any legislative changes. Until those documents appear, the early-2030s launch remains a reported target, not an approved government deadline.
