The Bank of Japan has launched an initiative to test blockchain technology as a means for financial institutions to settle deposits at the central bank. Announced by Governor Kazuo Ueda during the FIN/SUM 2026 conference in Tokyo, this initiative falls under a broader sandbox project aimed at exploring the use of central bank money across various settlement activities. These include domestic interbank transactions and securities transactions.
In the international arena, the Bank of Japan is actively participating in Project Agorá. This collaboration with multiple central banks and financial institutions focuses on creating tokenized central bank deposits, which promise to simplify cross-border payment processes. The initiative seeks to harness the capabilities of smart contracts and atomic transactions. Such advancements could potentially improve the efficiency of international payments by allowing participating central banks to issue tokenized representations of their reserves on distributed ledger systems.
The central bank’s leader stressed that central bank money is vital in providing trust for the economy, allowing different payment instruments to operate as safe and liquid assets. He emphasized that the integration of distributed ledger technology has evolved from mere experimentation into actual application within the financial services sector, illustrated by the rise of decentralized finance protocols.
Further showcasing its commitment to digital currency, the Bank of Japan initiated a pilot for a retail digital currency in 2023, aiming to evaluate the technical requirements for issuing digital cash. However, there has yet to be a decision on public implementation, largely influenced by Japan’s strong reliance on cash.
Ueda highlighted the necessity of ensuring interoperability across emerging blockchain networks that coexist with traditional payment systems. Without centralized oversight, users might navigate different systems, possibly leading to confusion regarding the value of various payment instruments.
Additionally, he discussed the potential for synergies between artificial intelligence and distributed ledger technology. Possible applications, such as AI-driven advisory services and automated collateral management, could leverage transaction data stored on these chains to enhance decision-making and operational efficiency.
