Major U.S. banks are currently restricting external AI agents from accessing customer accounts amid concerns over automated deposit management. FDIC Chair Travis Hill is now evaluating how these emerging technologies influence the safety and stability of the banking system.
Why it matters
With corporate deposits making up roughly half of the total banking system, regulators are monitoring how AI agents that automatically move funds could alter deposit volatility. This shift forces banks to balance new technological efficiencies against the risks posed to consumer and corporate accounts.
Corporate deposits represent 50% of the total deposits within the banking system. The stability of these funds is currently a key focus as institutions weigh the risks of automated AI agents.
The players
Travis Hill
The FDIC Chair who oversees bank supervision and is evaluating the risks that generative AI poses to the stability of deposits.
Citi
A major global bank that manages consumer and corporate deposits and is currently restricting external AI access to accounts.
Bank of America
A large national financial institution providing retail and corporate banking services that is limiting AI agent access to customer data.
JPMorgan Chase
A major financial institution that holds significant consumer deposits and is actively blocking third-party AI agents from linked accounts.
The details
AI agents are designed to execute financial transactions and move deposits automatically on behalf of customers. In response to potential security and liquidity risks, institutions like Citi, Bank of America, and JPMorgan Chase are blocking these external agents from gaining direct access to user accounts. Regulators are now navigating the intersection of innovation and safety as they adapt existing risk management guidance to address these automated processes.
Timeline
Earlier in 2026, the FDIC, OCC, and Federal Reserve released revised model risk management guidance.
Tuesday, October 20, 2026, FDIC Chair Travis Hill discussed the impact of AI on banking at industry events.
Money Landscape
The rise of AI agents represents a new frontier for the established 2026 model risk management guidance issued by federal regulators. Banks are now recalibrating their security protocols to fit within these oversight standards while managing the liquidity implications of automated fund transfers.
If you use third-party AI tools or financial assistants, expect them to have limited functionality when interacting directly with your primary bank accounts. Consult with your financial institution to understand which automated services they authorize for your specific account type.
The takeaway
The move to restrict AI agents highlights a push by banks to prioritize account security over automated convenience for now. Stay alert to updates from your own bank regarding which third-party applications are permitted to sync with your accounts to ensure your data stays protected.
