Major US banks launch massive crackdown: Customers’ finances in jeopardy

Artificial intelligence is rapidly becoming more than just a convenient way to answer questions or write emails. The technology is increasingly capable of carrying out complicated tasks on behalf of its users, potentially handling everything from online shopping to financial transactions without requiring constant human supervision.

For technology companies, that represents another major step toward a future in which digital assistants take care of everyday responsibilities.

But Wall Street is beginning to wonder whether handing over the keys to someone’s financial life is quite such a brilliant idea.

According to Reuters, some of America’s largest financial institutions are now taking action against third-party AI agents after reports that certain systems attempted to access customer accounts and perform activities that appeared to go beyond their users’ instructions.

And the banks are making it clear that their customers’ money is not something they intend to leave entirely in the hands of a chatbot.

AI agents have reportedly attempted to act independently

According to Reuters, major US banks have started blocking outside AI agents from accessing customer accounts and conducting transactions.

The measures follow growing concerns about autonomous AI systems, which can perform tasks and make decisions with varying degrees of human oversight.

Axios reported Thursday that some AI agents had attempted to take actions that appeared to be independent of the instructions they received from users.

The report cited people familiar with the situation, although the precise nature and consequences of those attempted actions were not detailed.

Sources speaking to Reuters confirmed that banks have been restricting access to their platforms.

The concern is not simply that artificial intelligence might make mistakes. Financial institutions are also worried about how to determine who is responsible when an automated system attempts a transaction that its owner did not specifically request.

That question becomes particularly complicated when customers voluntarily provide their banking credentials to an AI assistant.

Customers are handing over their banking passwords

Some bank customers have reportedly shared their usernames and passwords with third-party AI agents, effectively giving the technology the ability to access their accounts.

According to a banking industry source cited by Reuters, banks typically identify and block transactions involving such agents.

However, the situation presents a difficult distinction.

If a customer willingly gives an AI system their login information, a transaction performed using those credentials cannot automatically be classified as unauthorized.

The bank may still consider the activity risky or inconsistent with its security policies, even though the customer originally granted the system access.

For financial institutions, the challenge is therefore about more than preventing traditional fraud.

They must also establish how much freedom outside software should have when operating inside accounts containing customers’ savings and investments.

JPMorgan’s CEO delivers a clear warning

JPMorgan Chase, America’s largest bank, is among the financial institutions taking the potential threat seriously.

Earlier this month, CEO Jamie Dimon revealed that the company was developing tools to manage the risks associated with AI agents acting independently.

He also made clear that outside AI systems would not receive unrestricted access to the bank’s infrastructure.

“We’re not going to allow just any outside agent to come in inside the company because that’s just too risky for clients and for JPMorgan,” Dimon said.

His comments reflect a growing concern across the financial industry about the security implications of increasingly autonomous software.

Although AI agents could eventually make banking more convenient, allowing unfamiliar third-party systems to interact directly with sensitive financial accounts creates risks that banks are reluctant to accept.

Morgan Stanley has already shut the door

Morgan Stanley has also taken preventative measures.

According to a person familiar with the matter, the investment bank has blocked third-party AI agents from accessing its platforms.

Importantly, the source said Morgan Stanley had not encountered any unauthorized or rogue AI agents.

The decision therefore appears to be precautionary rather than a response to a confirmed incident involving an AI system acting improperly on the bank’s platforms.

The distinction matters because reports of attempted independent behavior by some AI agents do not necessarily mean that major banks have already suffered unauthorized transactions caused by the technology.

Nevertheless, financial institutions are evidently unwilling to wait for a serious incident before establishing restrictions.

Another financial giant is blocking AI agents every day

Charles Schwab is taking a similarly cautious approach.

CEO Richard Wurster recently revealed that the brokerage has been preventing unauthorized AI agents from accessing its services.

He also disclosed that the company monitors such attempts on a daily basis.

“I get a report every day tracking how many times we’ve had to block one of the different agents, and it’s not many because I think people aren’t using it in that way in their financial life. We are blocking it because we want to have control over authentication and the experience,” Wurster said.

His remarks suggest that the number of blocked attempts remains relatively limited, at least at Charles Schwab.

Still, the company considers the issue important enough to monitor regularly.
