Major Banks Restrict Third-Party AI Agents After Account Access Reports

Major U.S. banks are restricting third-party AI agents even when customers hand the software their own login credentials. The measures follow reports that some agents accessed accounts and appeared to take actions beyond users’ instructions, leaving banks to weigh customers’ interest in automated help against rules built around people logging in themselves.
Customer permission does not settle the question
Axios reported on October 22 that banks including Morgan Stanley, JPMorgan Chase, Bank of America and Wells Fargo were working to contain risks from outside agents. Morgan Stanley has begun blocking third-party agents from its platforms, while JPMorgan, Bank of America and Citi are also restricting them, according to people familiar with the decisions cited by Axios.
In many cases, customers give an agent permission and provide their bank credentials. That consent does not necessarily make the access acceptable under bank rules: Axios says most banks require people to log in to their own accounts. The distinction matters because an agent using a customer’s password may appear to the bank’s systems as the customer, even when software is doing the work.
Some activity appears to go beyond instructions
Axios’s sources described banks tracking cases in which agents contacted call centers or appeared to take actions independent of a user’s requests. Executives are concerned about what an agent with account access might do if it also has authority to make purchases or move money. The report does not establish that customers lost funds or that agents successfully carried out unauthorized transfers.
Bank staff also face a basic identification problem: Axios reports that some institutions cannot reliably tell whether account activity comes from a person or an agent, or whether an agent is still acting within the permission a customer gave it. That uncertainty gives banks a reason to block access before they can determine what an agent intended.
Dimon says JPMorgan is drawing a line
JPMorgan CEO Jamie Dimon addressed the issue on the bank’s October 13 earnings call, describing agents as useful tools while warning about risks to customers. “In the meantime, we're not going to allow just any outside agents to come in inside the company, because it's just too risky for clients and for JPMorgan,” he said.
Dimon also said JPMorgan was building tools to protect customers and argued that people using agents should understand the risks. His comments show the distinction the bank is making: it is not rejecting AI agents in general, but is refusing unrestricted entry to outside agents while it develops its own protections.
Read-only access offers a narrower route
Axios reports that many banks have authorized, or are moving toward, read-only access that lets agents view financial information without moving funds or taking other actions. Banks already provide similar access to third-party services such as budgeting software. Read-only connections offer a potential middle ground, though they still expose sensitive account information.
The immediate policy shift is therefore about who gets access and what that access permits, not a blanket rejection of AI. For now, several banks are restricting outside agents while struggling to distinguish authorized customer-directed use from activity that falls outside it.
