Major American banks are blocking third-party agents from using their services for fear that customers will suffer grave financial losses.
Banks like JPMorgan, Morgan Stanley, Bank of America, and Citi are just a few banks rushing to change their terms and conditions as AI agents gain access to their services.
Morgan Stanley has begun blocking AI agents from accessing their platforms entirely, while Bank of America and Citi are planning to restrict agent access, sources familiar with the matter told Axios.
JPMorgan Chase recently announced that it will be blocking AI agents as the banking giant doesn’t want “rogue agents” infiltrating their platform.
While some users grant AI agents full access to their sensitive data, others are accessing users' banking apps without explicit permission.
Banking executives have reportedly described the situation as “horrifying” and have classified AI agents as an emerging threat, due to the increasing number of users who want bots to handle their finances.
Major US banks are preparing for the potential fallout of AI agents, including a “day after” scenario, which would detail how quickly banks would secure and restore a customer’s account in the event of an AI bot error, Axios reports.

Grok Bot wants access to your bank
Despite the industry’s fears surrounding AI agents accessing users' bank accounts, tech CEOs like Elon Musk and his gaggle of followers are encouraging people to give Grok Bot access to their bank accounts.
Musk also encouraged users to hand over sensitive data to the AI agent so it can complete a transaction autonomously.
However, this has had negative effects on users because all Grok Bot agents share a network, meaning that they share information with each other.
One tech CEO discovered this when his personal banking audit was uploaded to his business Slack chat for his employees to see. Grok Bot exposed the CEO's private finances.
It's not only major US banks that are blocking AI agents. Amazon has blocked Grok Bot and Meta’s Muse after users started instructing their bots to make purchases on their behalf.
