Morgan Stanley, JPMorgan, Bank of America and Citi are preparing to block third-party AI agents from accessing their platforms, according to Axios. The report, citing industry sources, said some AI bots had accessed bank accounts without authorization and made transactions outside users’ instructions.

US banks are revising terms for third-party AI applications as they try to distinguish agents authorized by customers from systems accessing accounts improperly. Bank executives told Axios that making that distinction is becoming harder.
