Japan and US Banks Advance Blockchain Settlement Plans

Japan is moving to shift the settlement of stocks and government bonds onto blockchain infrastructure, joining a global push by financial institutions to replace traditional, multi-day settlement cycles with real-time, 24/7 digital systems [1]. This initiative, which involves the Bank of Japan and the country’s three largest banks, seeks to mitigate counterparty risk by converting central bank balances into digital tokens [1].

Institutional adoption accelerates

The broader market for tokenized assets has expanded significantly, growing from approximately $2 billion in March 2024 to more than $38 billion today [2]. Within this sector, tokenized U.S. Treasuries have seen a sharp increase, rising from $721 million to roughly $16 billion [2]. Major financial institutions, including BlackRock and JPMorgan, are increasingly utilizing public blockchain infrastructure to manage funds and debt, with BlackRock’s BUIDL fund alone managing more than $2.6 billion in assets [2].

In the United States, 39 state banking associations have formed the BankChain Alliance to build a nationwide, industry-owned blockchain network targeting a 2027 launch [3]. This network intends to support tokenized deposits, stablecoins, and automated settlement, aiming for interoperability with other blockchain systems [3]. These efforts coincide with initiatives from major lenders like JPMorgan Chase, Bank of America, and Citi, which are also developing on-chain money infrastructure [3].

The mechanics of settlement

The Japanese proposal focuses on wholesale settlement, a move designed to avoid the surveillance and disintermediation concerns that have hindered retail central bank digital currency (CBDC) projects [1]. By utilizing a wholesale system, the project aims to compress settlement cycles that currently take two business days for equities and one for government bonds [1]. However, experts note that instant settlement removes the benefits of netting, which may increase liquidity demands as firms must hold the full cash and securities at the moment of trade [1].

While Japan’s project is in the early study phase with no technology yet selected, it reflects a defensive strategy to maintain competitiveness against the United States and Europe, where tokenized securities infrastructure is already under development [1]. The project is expected to produce a development plan by early 2027, with an operational launch targeted for the early 2030s [1].

What to watch

• Technology Selection: Monitor which blockchain or distributed ledger technology the BankChain Alliance and Japanese study groups select, as this will dictate the interoperability of these new settlement rails [1, 3].
• Liquidity Requirements: Observe how financial institutions manage the increased liquidity demands resulting from the removal of netting in zero-cycle settlement environments [1].
• Regulatory Frameworks: Watch for further guidance from the Japanese Financial Services Agency, which continues to balance institutional tokenization projects with increased enforcement against consumer-facing crypto fraud [1].

The shift toward on-chain settlement represents a fundamental change in how traditional financial assets are transferred and used as collateral. Whether these disparate, bank-led networks can successfully integrate into a unified global system remains the primary open question for the industry.
