Japan plans blockchain-based settlement system for stocks and government bonds

Aug 25, 2026

Japanese financial regulators and major banks are planning a national blockchain-based settlement system to enable instant, 24/7 trading of stocks and government bonds. By tokenizing commercial bank reserves held at the Bank of Japan into a wholesale digital currency, the system aims to compress settlement times from up to two days to near-zero. The initiative seeks to modernize Japan's $7 trillion bond market and keep pace with capital market tokenization in the United States and Europe.

Blockchain settlement infrastructure plan

▪The Japanese Financial Services Agency, Ministry of Finance, Bank of Japan, and local financial institutions plan to establish a study group in the summer of 2026 to design a blockchain-based payment infrastructure for stocks and Japanese government bonds
▪The Japanese regulatory study group expects to produce a development plan by early 2027, with the blockchain-based settlement system potentially launching in the early 2030s if formally approved

Tokenized central bank reserves

▪The tokenized Bank of Japan deposits would function as a wholesale central bank digital currency used exclusively for interbank payment settlement rather than individual retail transactions
▪The proposed Japanese settlement system would convert a portion of the current account deposits that commercial banks hold at the Bank of Japan into digital tokens on a blockchain network

Settlement time reduction

▪Japan previously reduced Japanese government bond settlement to one day in 2018 and stock settlement to two days in 2019, while the United States shortened stock settlement to one day in 2024
▪The proposed blockchain infrastructure aims to reduce settlement times for Japanese stocks from two business days (T+2) and Japanese government bonds from one business day (T+1) to near-real-time speed

Japanese bank blockchain pilots

▪In April 2026, the Japan Securities Clearing Corporation launched a trial with Mizuho, Nomura, and Digital Asset to explore using Japanese government bonds as collateral on the blockchain
▪Roughly 40 Japanese regional and online banks announced in August 2026 that they will launch a proof-of-concept for interbank transfers using tokenized deposits
▪Mizuho Bank, MUFG, and SMBC are collaborating on a stablecoin pilot project to innovate payment systems using blockchain technology

Global capital market competition

▪An April 2024 survey by Nomura and Laser Digital indicated that nearly 80% of Japanese institutional investors plan to allocate to cryptocurrency within three years
▪Japanese financial media warned that Japan risks losing institutional investors to other jurisdictions as the United States and Europe modernize capital markets through tokenization and 24/7 trading
▪The Bank of Japan is participating in Project Agorá, a Bank for International Settlements initiative involving seven central banks and over 40 financial institutions to test tokenized cross-border payments

Japan bond market stress

▪The 10-year Japanese government bond yield sits near 2.9% and the 30-year yield trades above 4% in August 2026, representing multi-decade highs for Japanese borrowing costs
▪Japan's outstanding government bonds and bills total approximately 1,166 trillion yen, which is equivalent to roughly $7 trillion
