Japan Plans Blockchain Network for Real-Time Stock and Bond Settlements

Summary

• Japan’s financial authorities plan blockchain infrastructure that could reduce stock and government bond settlements from two days to real-time processing.
• Banks would tokenize central bank account balances while regional institutions test tokenized deposits for blockchain-based interbank transfers across Japan.
• Regulatory amendments, stablecoin pilots, and tokenized bond trials are building the foundation for Japan’s coordinated digital financial market infrastructure.

Japan’s Financial Services Agency, Ministry of Finance, and central bank are developing blockchain infrastructure for settling stocks and government bonds. The initiative aims to replace Japan’s two-day settlement period with real-time transactions across regulated financial markets.

According to Nikkei Asia, authorities will work with domestic financial institutions during the summer and could complete the development plan by early 2027. The document will define the blockchain’s design and divide responsibilities among agencies and participating institutions. Additionally, it will establish a roadmap covering development, testing, and eventual deployment.

Furthermore, authorities may include the project within a multi-year strategic investment framework planned for fiscal 2027. That arrangement could support coordination and financing throughout the development process.

Banks would tokenize portions of their current account balances held at the Bank of Japan. Financial institutions could then use those digital balances to settle securities transactions through the blockchain network.

Consequently, buyers would receive securities while sellers would receive payments through one coordinated process. Faster settlements could reduce delays, lower counterparty risks, and help institutions manage liquidity efficiently.

Tokenized Deposit Trials Support Japan’s Blockchain Strategy

About 40 regional and online banks have announced a proof of concept involving tokenized deposits. Testing could begin during August and will examine blockchain-based interbank transfers.

This experiment forms another part of Japan’s broader effort to modernize its regulated payment infrastructure. Moreover, it could demonstrate how tokenized deposits perform across multiple banking institutions.

Japan has also strengthened the legal foundation supporting digital assets. In July, lawmakers approved amendments covering approximately 105 cryptocurrencies. The amendments will classify those cryptocurrencies as financial instruments from fiscal 2027. They also establish separate taxation of cryptocurrency at an effective rate of nearly 20%.

Meanwhile, Japan Securities Clearing Corporation has launched a trial involving tokenized government bonds. Mizuho, Nomura, and Digital Asset are examining their use as blockchain-based collateral.

Mizuho Bank, MUFG, and SMBC are also developing a stablecoin pilot with regulatory support. Together, these projects could connect tokenized money, securities, and regulated institutions within Japan’s financial system.
