Bank of Japan to Test Blockchain for Real-Time Settlement of Bank Deposits

Governor Kazuo Ueda announced at FIN/SUM 2026 that the Bank of Japan will conduct a blockchain sandbox experiment for current account deposit settlement, potentially extending to interbank transfers and megabank-issued stablecoin integration.

Fact Check
An official Bank of Japan speech explicitly describes its CBDC pilot and technical experiments on settlement using central bank money with blockchain/DLT, which directly supports that the BOJ conducted internal tests of a blockchain-based settlement system. This is a primary, on-the-record BOJ source with high authority and relevance. An academic preprint discusses the BOJ’s reported technical experiments, providing consistent secondary context. An industry news report also aligns, summarizing BOJ-confirmed blockchain-based settlement experiments linked to Project Agorá. No credible source in the set contradicts the claim; the remaining items are either supportive context or irrelevant. Given the direct BOJ confirmation and corroborating secondary accounts, the statement is very likely true.

Summary

Bank of Japan Governor Kazuo Ueda announced at FIN/SUM 2026 in Tokyo that the central bank will launch a blockchain-based sandbox experiment to settle current account deposits. The project will test the use of distributed ledger technology for interbank settlements and may explore integration with stablecoins issued by Japan’s megabanks. The initiative builds on the BOJ’s ongoing retail central bank digital currency (CBDC) pilot and its participation in Project Agorá, which examines tokenized wholesale central bank deposits for cross-border payments. The sandbox is designed to assess technical feasibility and compatibility with existing infrastructure rather than signal immediate deployment.

Terms & Concepts
  • Central Bank Digital Currency (CBDC): A digital form of sovereign currency issued and backed by a central bank, designed for retail or wholesale use.
  • Stablecoin: A type of cryptocurrency designed to maintain a stable value, typically pegged to a fiat currency and sometimes issued by financial institutions.
  • Project Agorá: An international initiative exploring the issuance of tokenized wholesale central bank deposits on blockchain to enhance cross-border settlement efficiency.
