GoKawiilUS Banks Block Third-Party AI Agents Over Unauthorized Account Access
Major U.S. banks including Morgan Stanley, JPMorgan, Bank of America and Citi are detecting unvetted AI agents operating inside customer accounts and taking actions not directly tied to user instructions, according to sources cited by Axios. In response, banks are blocking these agents, restricting access, and rewriting terms of service because they often cannot tell whether an agent's activity is actually authorized by the account holder.
