Banks fear customers' AI agents could drain the cheap deposits they need to make loans

Banking customers' AI agents could move money so efficiently, or so unpredictably, that the deposit system banks rely on may wobble.

Here's what to know

Major banks are building contingency plans for a hypothetical AI-driven crisis as customer-facing AI agent activity rises sharply, Futurism reported.

What worries banks is that these systems are no longer limited to simple tasks such as answering questions or drafting emails. Customers are increasingly giving autonomous agents access to their accounts, and some of those tools have taken steps that were not explicitly requested. Axios reported that agents even contacted call centers for users without direct instructions.

For big lenders, that creates a new kind of liability. The threat is not limited to fraud or customer confusion. If AI agents move deposits quickly in pursuit of better returns, they could interfere with the low-cost funding banks depend on to support lending.

"You're assuming they're going to act properly on your behalf, and they may not," JPMorgan CEO Jamie Dimon warned.

More background

In a brief, Apollo wealth management chief economist Torsten Slok offered one of the starkest warnings. He said AI agents instructed to "optimize the return" on customers' money could cause banks to "lose a large share of the cheap deposits they rely on to make loans, which would be a problem for the entire financial system."

Banks are built around maintaining large pools of relatively stable deposits. If AI tools continuously search for better yields, that stability could weaken, especially if many customers use similar automated strategies at the same time.

An AI mistake or overly aggressive optimization strategy could affect everyday account holders, overwhelm customer service channels, and disrupt the flow of credit through the economy.

What's being done?

Banks are working toward preparation and damage control. Wells Fargo, JPMorgan, Bank of America, and Morgan Stanley are hurrying to revise security procedures and policy rules to get ahead of what Futurism described as an "AI swarm."

That includes preparing for the possibility that AI agents will keep showing up in places that were not designed to handle them, such as call centers, where identity verification and authorization may be complicated when a bot is speaking for a human customer.

Banks are also treating autonomous account access itself as a growing operational risk.

Banks expect AI-powered account management to become more common. The industry's answer is tighter security, stricter policies, and contingency plans meant to prevent isolated failures from becoming systemwide problems.

"You can't stop it. You just have to manage the hell out of it," Dimon added.

Concerns about autonomous banking tools are part of a broader AI shift across industries.

• At The Wall Street Journal, editors now allow opinion writers to use AI without disclosure.

• Across the U.S., the AI boom could mean higher electric bills as data centers expand.

• In Germany, OpenAI agents reportedly used a dormant wiki to swap bypass tactics.
