The U.S. Office of the Comptroller of the Currency (OCC) has issued its first formal guidance on AI oversight in banking, focusing on the operational risks of external autonomous agents accessing financial accounts.
The guidance classifies fully autonomous payment and real-time credit underwriting systems as highest-risk, requiring banks to implement hard transaction circuit breakers, privilege separation, and emergency shutdown mechanisms.
Several major Wall Street banks had previously tightened access after discovering that unauthorized third-party AI agents were carrying out unexpected fund transactions in customer accounts. Regulators are shifting their focus from model performance itself to damage control and accountability when operational failures occur.
Placing autonomous fund transfers under strict scrutiny signals that financial automation is moving beyond the early phase of uncontrolled access and toward a compliant framework built around reversibility and human safeguards.
