Key Takeaways
- Japan plans to explore blockchain infrastructure enabling instant, 24/7 settlement of government bonds and stocks.
- The FSA, Finance Ministry, Bank of Japan, and financial institutions aim to finalize a development plan in early 2027.
- The system could eliminate current settlement delays, reduce counterparty risk, and eventually support international remittances.
Japan is preparing a blockchain-based financial infrastructure that could enable instantaneous, around-the-clock settlement of government bonds and stocks, marking a significant step toward modernizing one of the world’s largest financial markets.
The Financial Services Agency, Ministry of Finance, Bank of Japan, and major financial institutions are expected to establish a study group this summer, according to Nikkei. The participants aim to formulate a development plan as early as the beginning of 2027.
The plan will address the blockchain architecture, the division of responsibilities between public authorities and private institutions, and a roadmap for implementation.
Subject to formal approval, the infrastructure could become operational within several years, potentially as early as the early 2030s.
Japan has already conducted experiments involving distributed ledger technology. However, the latest initiative is reportedly the first to establish a clear timeline for developing a production-ready system.
Blockchain Could Eliminate Settlement Delays
Under Japan’s existing market structure, stock transactions typically settle two business days after execution, while Japanese government bond trades settle the following business day. This creates a delay between agreeing to a transaction and completing the transfer of cash and securities.
A blockchain-based system could reduce that gap by recording ownership changes and payments on shared digital infrastructure.
In principle, investors could receive and reinvest the proceeds from an asset sale almost immediately, rather than waiting one or two working days.
Faster settlement could also reduce counterparty exposure, release capital tied up during the settlement period, and improve market efficiency. The initiative may eventually expand beyond domestic securities to areas such as international remittances.
However, continuous settlement would require more than a technical upgrade.
Banks, brokerages, and other institutions would need access to cash and collateral outside conventional business hours. Regulators would also need to determine how the system handles custody, cybersecurity, operational failures, and transaction finality.
Where Can Investors Already Trade 24/7?
Cryptocurrency exchanges currently provide the clearest example of uninterrupted markets. Investors can trade assets such as Bitcoin and Ether every day, including weekends and public holidays.
CME Group also introduced 24/7 trading for regulated cryptocurrency futures and options in May 2026, extending continuous access beyond spot crypto platforms.
Foreign exchange operates nearly 24 hours per day from Monday to Friday as activity moves between Asia, Europe, and North America, but it generally closes at weekends.
Some brokers and alternative trading systems also provide overnight access to selected US stocks and exchange-traded funds, although that does not constitute uninterrupted seven-day trading across the broader equity market.
Traditional exchanges are nevertheless moving in that direction.
The New York Stock Exchange is developing a platform designed to support 24/7 trading and immediate on-chain settlement of tokenized US-listed stocks and ETFs, subject to regulatory approval.
Japan Targets an Always-On Financial System
Japan’s proposal goes beyond simply extending trading hours; it focuses on settlement, the final exchange of securities and money after a trade.
Markets can remain open overnight while relying on traditional clearing systems that complete transactions later. Japan’s planned infrastructure would instead seek to make the post-trade process available continuously, including outside banking hours.
That distinction could make the project particularly consequential for Japanese government bonds, which form one of the world’s largest sovereign debt markets.
It could also help Tokyo compete with financial centers developing tokenized securities and longer trading sessions.
The study group must still resolve major questions about governance, interoperability, and the legal status of blockchain records.
Yet the timetable signals that Japan is moving beyond isolated trials toward a practical overhaul of its market infrastructure, one where stocks and government bonds could eventually settle instantly at any hour of any day.
