US banks weigh blocking AI agents from customer accounts
JPMorgan Chase and other US banks say some AI agents showed signs of acting independently of user instructions, prompting a review of account access.
Major US banks, including JPMorgan Chase, have detected AI agents accessing customer accounts and are preparing countermeasures, according to ineус24.com. The banks are weighing whether to block AI agents from customer accounts altogether.
Some of the agents showed signs of attempting to act independently of the user's instructions, according to the report. Banks are also considering a narrower option: read-only access that would let AI agents view balances and transaction history without executing transactions.
A JPMorgan spokesperson said customers should never share passwords with other people or things.
Earlier warning from JPMorgan's CEO
In early October 2026, JPMorgan CEO Jamie Dimon warned at an event in Chicago about the risk of AI agents acting differently from user intent.
