Japan is moving toward blockchain-based settlement for traditional securities, with regulators and some of the country’s largest banks and brokerages testing infrastructure designed to settle stocks and bonds almost instantly rather than through conventional multi-day processes. The Financial Services Agency is supporting a demonstration experiment that will record and manage transfers of rights to Japanese government bonds, corporate bonds, investment trusts and stocks using blockchain technology.
The securities transfers will then be linked with payments made using stablecoins, creating the possibility of atomic delivery-versus-payment settlement in which the movement of an asset and the corresponding cash occur together. Finance Minister and Financial Services Minister Satsuki Katayama said the project could allow Japan to achieve “advanced and faster settlement” in the Tokyo market and position the country near the forefront of global competition to modernize capital-market infrastructure. The project is being supported through the FSA’s Payment Innovation Project, or PIP, which was established to help financial institutions test new payment and settlement technologies while working through legal and regulatory questions.
Blockchain Could Compress Settlement From Days to Seconds
Japan’s current securities infrastructure already uses delivery-versus-payment mechanisms to reduce principal risk, but settlement timing varies depending on the instrument. Japanese government bond transactions moved to a T+1 standard in 2018. JSCC also currently uses the Bank of Japan’s real-time gross settlement infrastructure for eligible JGB settlement between itself and clearing participants. The blockchain initiative goes further by attempting to synchronize the securities and digital-cash legs of transactions through programmable infrastructure.
Rather than waiting for separate systems and intermediaries to reconcile ownership and payments, blockchain could make both transfers effectively simultaneous. The experiment brings together major securities companies and Japan’s megabanks. The FSA said participants intend to test blockchain recording and management of rights while connecting those transfers with stablecoin payments. Separately, Mitsubishi UFJ Financial Group is testing real-time settlement of Japanese government bond repo transactions using the Canton Network, working with Digital Asset and Progmat. That proof of concept aims to support 24-hour atomic settlement while leaving the underlying JGBs within Japan’s existing book-entry system rather than replacing them with entirely new blockchain-native securities.
Japan Builds Stablecoin and Tokenization Infrastructure in Parallel
The settlement initiative fits into a broader Japanese push to integrate blockchain technology with regulated finance. In April, Mizuho Financial Group, Nomura Holdings, Japan Securities Clearing Corporation and Digital Asset launched another proof of concept using the Canton Network to test blockchain-based management of JGB collateral. That project is examining whether ownership transfers and book-entry records can be synchronized through blockchain while preserving the existing legal status of Japanese government bonds. It also targets real-time, 24/7 cross-border collateral movement.
Japan’s three largest banking groups — MUFG, Sumitomo Mitsui Financial Group and Mizuho Financial Group — are meanwhile preparing to jointly issue stablecoins during the fiscal year ending March 2027. Those initiatives could eventually converge. Blockchain-based securities provide a digital asset leg, while regulated yen stablecoins or tokenized bank deposits can provide programmable cash. Combining the two makes atomic settlement possible without forcing either participant to assume the risk that one side of a transaction completes while the other fails. The potential benefits include lower counterparty exposure, reduced collateral requirements, longer operating hours and faster reuse of capital.
Japan is not yet replacing its existing stock and bond settlement infrastructure, however. The FSA-backed initiative remains an experiment, and commercialization would require participants to resolve legal, operational, interoperability and market-structure issues. Japan is also separately considering a conventional move toward T+1 settlement for equities, although Citi said earlier this year that such a transition is unlikely before 2030. The blockchain trials therefore represent a more ambitious alternative: rather than simply reducing settlement by one business day, Japan is examining whether distributed ledgers and regulated digital money can ultimately compress parts of securities settlement toward real time and make financial-market infrastructure operate around the clock.
