BofA Issues Credential Warning
Bank of America sent customers an email titled "Protecting Your Finances in an AI world" explicitly warning not to share usernames and passwords with third parties, including AI Agents claiming to act on customers' behalf. If financial losses result from AI Agent access to accounts, customers may have to bear responsibility themselves. Banks say it is difficult to identify whether AI Agents are legitimately authorized or controlled by malicious threat actors, further heightening caution.
Large Banks Impose Collective Limits
Facing the shift of AI Agents being able to execute transactions on users' behalf, several large banks have taken action. JPMorgan Chase, Bank of America and Citi have blocked AI Agents from accessing customer accounts. TD Bank US has also restricted access by some third-party personal AI Agents where authentication is required. Wells Fargo is informing customers about responsibilities related to using AI tools. Bill Demchak, CEO of PNC Financial Services Group, stated even more explicitly that purely agentic transactions will never happen.
Existential Threat and Human Advantage
Udi Ziv, CEO of fintech company Personetics, said letting customers link bank accounts to large language models poses an "existential threat" to the banking industry, potentially severing the bank-customer relationship and reducing banks to an "invisible utility." A Fitch Ratings report also noted that the banking industry will face moderate AI-related business disruption risk over the next five years, mainly from technology competition. Udi Ziv believes human service channels are banks' biggest moat against large language models and AI Agents, with banks holding broad and deep financial data and the ability to serve customers through human channels such as financial advisors, branches and call centers.
$31.43 Egg Lesson
The case of Washington Post reporter Jeffrey A. Fowler showed his AI Agent spent 31.43 dollars on a dozen eggs with his credit card without instruction or approval, highlighting the potential risks. JPMorgan Chase put up a billboard in Charlotte, North Carolina, with the slogan "Money questions, human answers," emphasizing the value of human service. Experts advise customers to keep bank login credentials private, clearly understand what information is shared and what specific actions AI is authorized to take. While AI Agents can be used to analyze spending and help set budgets, it is recommended to avoid letting them execute transactions on their own to protect financial security.
