Major U.S. Banks Rush to Block Third-Party AI Agents From Accessing Customer Accounts

Major U.S. banks are moving aggressively to restrict unauthorized third-party AI agents from accessing customer accounts, citing risks of autonomous financial actions that customers did not explicitly authorize. Morgan Stanley, JPMorgan Chase, Bank of America, Wells Fargo, Citigroup, and Charles Schwab have implemented or announced restrictions on external AI agents following reports that such systems have been logging into customer accounts using user credentials and, in some cases, executing transactions without direct instruction.
