Major U.S. banks reportedly block third-party AI agents from customer accounts

Axios reports that several U.S. banks are restricting third-party AI agents after some appeared to act independently of user instructions. It says Morgan Stanley has begun blocking agents, though the bank says it has not observed rogue agents accessing its platforms. Reuters, in an article published by The Economic Times, reports that some customers gave agents their login credentials and that banks typically flag and block those transactions.
