Major US banks block outside AI agents from logging into customer accounts

Morgan Stanley, JPMorgan Chase, Bank of America and other large US banks are blocking outside AI agents that log into accounts with customer credentials, The Decoder reported on October 23. The access breaks bank policy that account holders log in themselves, and banks struggle to tell whether an agent really acts for the user. Most banks want agent permissions limited to read-only. The report does not say whether any bank allows other forms of agent access.
