Japan is preparing to explore a 24/7 blockchain settlement system that could process stock and government bond trades — potentially cutting settlement times and bringing central-bank money onto distributed ledgers, Nikkei reported on Aug. 26. What’s being proposed - The Financial Services Agency (FSA), Ministry of Finance (MOF), Bank of Japan (BOJ) and participating financial firms are expected to form a study group in the summer of 2026, with an initial development plan targeted for early 2027, according to Nikkei. The government bodies had not issued a formal announcement when the report was published. - If the plan is approved and proceeds through development, the infrastructure could potentially go live in the early 2030s, though no final decision has been made. Why it matters - Japan’s equity trades currently settle on a T+2 cycle (cash two business days after a trade); most Japanese government bonds settle the next business day. A blockchain-based system could bring securities transfers and cash payments much closer together — or even enable simultaneous delivery-versus-payment — letting investors access sale proceeds faster and reinvest sooner. - Faster, real-time settlement reduces counterparty exposure windows but also imposes new liquidity and operational demands on banks, brokers and other market participants. How this ties into BOJ work and private initiatives - The proposal builds on ongoing BOJ experiments. In March, BOJ Governor Kazuo Ueda said the bank is testing settlements that use commercial banks’ current account deposits on blockchain infrastructure. BOJ officials have described this work as exploring tokenized central-bank account deposits (wholesale CBDC), which could support delivery-versus-payment settlement. - That BOJ work is distinct from Japan’s retail digital-yen pilot; the government is still researching retail CBDC technology and has not decided whether to issue one. - Japan’s private sector is already active in tokenized securities: Progmat recently migrated ¥452 billion of managed tokenized securities onto a dedicated Avalanche network. SBI Holdings and Startale are building Strium, a blockchain intended for round-the-clock tokenized securities trading, with a public testnet planned for 2026. - Separately, Japan’s three largest banks are developing a shared yen stablecoin framework aimed at live transactions by March 2027, following an FSA-backed corporate payments pilot. Key questions the study group will tackle - Should Japan build a new national blockchain, interconnect several regulated networks, or link distributed ledgers to existing market systems? - Technical architecture, roles for public vs. private participants, implementation timetable, and funding. - Governance, cybersecurity, transaction privacy, operational resilience, and procedures for reversing erroneous or unauthorized transfers. - How to support 24/7 operations — which would require market participants and regulators to sustain services outside current market hours. - Potential expansion of use cases, such as international remittances. Next steps and caveats - The next confirmed milestone would be an official announcement naming the participating institutions and setting the study group’s mandate. The early-2027 development plan is expected to outline architecture, testing stages, funding and any needed legal changes. - Until official documents are released, the summer-2026 study-group start, early-2027 plan and an early-2030s launch are reported targets rather than approved government deadlines. Bottom line Japan is moving from experimentation to planning: public authorities and private firms are lining up around the possibility of tokenized securities and wholesale CBDC-style cash on-chain. The outcome could reshape settlement for mainstream equities and government debt — but significant policy, technical and operational hurdles remain before a 24/7 blockchain settlement system becomes reality.
