Bank of Japan eyes tokenized central bank money in blockchain push
Bank of Japan Governor Ueda Kazuo said the rapid integration of blockchain and artificial intelligence is reshaping the financial system, positioning central banks to play a pivotal role in anchoring trust as crypto-linked infrastructure matures.
- The BoJ is exploring issuing or connecting central bank money to blockchain networks, including through Project Agorá and domestic sandbox testing.
- Japan’s retail CBDC program remains active, with technical experiments aimed at preparing digital cash as a future “anchor of trust.”
- Ueda warned that fragmented blockchain systems could create systemic risk unless central bank money bridges networks and ensures settlement finality.
Bank of Japan’s Ueda backs blockchain settlements, advances CBDC experiments
Speaking at FIN/SUM 2026 in Tokyo, Ueda described blockchain as moving firmly into its “implementation phase,” with decentralized finance (DeFi), smart contracts and tokenized assets increasingly influencing settlement, payments and cross-border finance.
He emphasized that blockchain’s programmability, particularly atomic transactions that bundle multiple actions into a single execution, could streamline complex processes such as delivery-versus-payment (DvP) and cross-border transfers.
For crypto markets, the speech revealed two key themes: interoperability and settlement in central bank money.
Ueda warned that a fragmented ecosystem of multiple blockchains and traditional payment rails could create conversion bottlenecks and systemic risks if interoperability is not ensured. He suggested central bank money, potentially in tokenized form, could function as a bridge across networks, preserving the “singleness of money” while enabling innovation.
The BOJ is advancing several initiatives with direct implications for digital assets. Its retail central bank digital currency (CBDC) pilot continues technical testing, while Project Agorá — a joint effort with other central banks and major financial institutions — is exploring tokenized central bank deposits on blockchain networks for cross-border payments.
A separate BOJ sandbox is testing how current account deposits at the central bank could be used to settle transactions conducted on distributed ledgers.
Ueda also highlighted AI’s growing role in analyzing blockchain transaction data for risk management and AML/CFT compliance, signaling closer scrutiny of crypto-linked activity even as innovation expands.
The message to markets was clear: blockchain-based finance is no longer experimental. But its long-term stability, Ueda said, will hinge on central banks embedding trust, liquidity and settlement finality into the next generation of digital infrastructure.
