Japan Explores Blockchain for Government Bond Transactions

Japan is reportedly preparing to develop a blockchain-based settlement system that could allow stock and Japanese government bond transactions to be settled in cash immediately and around the clock. According to a report from Nikkei, the Financial Services Agency, Ministry of Finance, Bank of Japan (BOJ) and financial institutions plan to establish a study group this summer to explore the project.

The group is expected to determine how the blockchain infrastructure should be designed, define the responsibilities of public authorities and private financial institutions, and prepare a development roadmap in early 2027. If the project receives formal approval, the system could begin operating in the early 2030s.

Blockchain could rnable real-time settlement

The proposed infrastructure would tokenize a portion of the deposits that commercial banks currently hold in their BOJ current accounts. These digital tokens could then circulate on the blockchain and be used for interbank settlement, potentially allowing transactions to be completed immediately rather than waiting for the existing settlement cycle. The approach could also make settlement available outside traditional market operating hours.

Japan looks to modernize market infrastructure

Currently, standard equity trades in Japan settle on a T+2 basis, meaning transactions are finalized two business days after execution. Domestic Japanese government bond trades generally settle on T+1, or one business day after the trade. A blockchain-based system could significantly shorten these timelines and reduce settlement delays across both markets.

Public and private institutions to develop framework

The planned study group will bring together regulators, the central bank, government authorities and financial institutions to determine how the system could operate within Japan’s existing financial framework. The initiative represents another step toward integrating blockchain technology into traditional market infrastructure, with the potential to support faster and more flexible settlement across major financial assets.
