Japan plans blockchain system for faster stock and bond settlements by 2030s

Japan to build blockchain system for stock and bond settlements

Japan’s top financial regulators are planning a new system that uses blockchain technology to settle stocks and government bonds faster. The system aims to reduce the current two-day settlement period to real time.

The Financial Services Agency (FSA), Ministry of Finance, and Bank of Japan will work with local institutions starting this summer to create a development plan. The plan is expected by early 2027.

A blockchain is a digital ledger that records transactions across many computers in a way that makes it hard to change or hack. This technology is often used in cryptocurrencies like Bitcoin.

Key details of the plan

• The development plan will outline the blockchain’s design, assign responsibilities to agencies and institutions, and set a timeline for the project.
• If approved, the system could launch within a few years and be fully operational in the early 2030s.
• The project may be part of Japan’s multi-year strategic sector investment framework starting in fiscal 2027.
• Some bank accounts held at the Bank of Japan will be tokenized on the blockchain network. Tokenization means converting assets into digital tokens that can be traded or settled on a blockchain.

What Japan’s regulators say

The Financial Services Agency, Ministry of Finance, and Bank of Japan are leading the initiative. They will collaborate with local financial institutions to create the development plan by early 2027.

The goal is to speed up settlements for stocks and government bonds, which currently take two days to complete.

Other blockchain projects in Japan

This initiative follows other recent efforts to integrate blockchain into Japan’s financial system:

• In July 2026, Japan passed amendments to classify about 105 cryptocurrencies as financial instruments, with changes taking effect in fiscal 2027. The amendments also introduce a separate crypto tax rate of around 20%, much lower than the current top rate of 55%.
• Earlier in August 2026, the FSA created a dedicated division for cryptocurrencies and stablecoins. A stablecoin is a type of cryptocurrency designed to have a stable value, often pegged to a traditional currency like the US dollar.
• In April 2026, the Japan Securities Clearing Corporation tested using blockchain for government bonds as collateral in partnership with Mizuho, Nomura, and Digital Asset.
• Japan’s three major banks—Mizuho Bank, MUFG, and SMBC—are working on a stablecoin pilot project backed by the FSA to improve payment systems.
• Around 40 regional and online banks in Japan announced a proof-of-concept for interbank transfers using tokenized deposits, with testing set to begin as early as August 2026.

What is confirmed

• Japan’s FSA, Ministry of Finance, and Bank of Japan are working on a blockchain-based system for stock and government bond settlements.
• The development plan is expected by early 2027.
• The system aims to be fully operational in the early 2030s.
• The goal is to reduce settlement times from two days to real time.
• Some bank accounts at the Bank of Japan will be tokenized on the blockchain.
• Japan has recently passed laws and created regulatory divisions to support blockchain and digital assets.

What is still unclear

• The exact design and technical details of the blockchain system have not been released.
• It is not confirmed which specific institutions will be involved beyond the regulators and some banks.
• The timeline for launching the system after the 2027 plan is not fixed.
• How the tokenized bank accounts will function in practice is not yet explained.

Why this matters for financial markets

Faster settlement times can reduce risks and costs in trading stocks and bonds. Real-time settlement means transactions are completed almost instantly, which can improve efficiency and liquidity in financial markets.

Using blockchain technology could also make the settlement process more transparent and secure. This initiative positions Japan as a leader in adopting blockchain for traditional financial systems.
