Ueda outlines central bank role in AI and blockchain finance
Bank of Japan Governor Kazuo Ueda addressed the FIN/SUM 2026, discussing the evolving financial ecosystem shaped by AI and blockchain. He emphasized the central bank's crucial role as an anchor of trust amid these technological advancements.
Programmable finance and AI's precision
Blockchain technology, particularly in decentralized finance (DeFi), offers high programmability through smart contracts, enabling bundled transactions like borrowing and repayment.
Efforts are underway for synchronous cross-border payments among multiple financial institutions.
AI, rapidly proliferating, allows for swift and precise analysis of big data, integrating with blockchain for enhanced financial services such as AI-driven advisory, automated collateral assessments, and effective anti-money laundering (AML/CFT) through pattern detection.
For this new ecosystem to thrive, transparency, authenticity, and robust payment safety are crucial.
Challenges include ensuring interoperability between conventional and blockchain-based systems, as multiple systems are expected to coexist.
The anchor of trust in a digital age
Central banks serve as an anchor of trust by ensuring price stability and safeguarding payment systems.
Central bank money provides the foundation for the singleness of money, allowing all payment instruments to be exchanged at par value, preventing historical risks.
It also contains systemic risk in large-value payments as the safest settlement asset.
The Bank of Japan is actively engaged in a retail central bank digital currency (CBDC) pilot, Project Agorá (tokenized central bank money for cross-border payments), and a domestic sandbox project for blockchain settlements.
These initiatives aim to enhance the BOJ-NET and ensure the central bank's role in the new financial ecosystem.
Navigating the digital frontier's complexities
Ueda's speech effectively highlights the transformative potential of AI and blockchain, alongside the foundational role of central bank money.
However, the ambitious scope of these projects, particularly in ensuring interoperability and managing smart contract risks, presents significant implementation challenges.
While the Bank of Japan's proactive engagement is commendable, the path to a secure and integrated digital financial ecosystem remains long and requires continuous international collaboration.
