Jamie Dimon bars outside AI agents from JPMorgan accounts

JPMorgan's decision comes as big tech rolls out AI agents designed to help with personal finances, and banks are now drawing a line at agents accessing account information. The bank's concerns follow several security incidents involving "rogue" AI agents that gained unauthorized access to a public Medicare statistics service, a government portal of health data.

A Cloud Security Alliance research note last month found that the risks of AI agents extend beyond controlled testing. It summarized a cybercrime campaign in which three open-source AI agents allegedly worked together to breach at least 27 organizations and take more than 600,000 credit card records from two of them. The note advised enterprises to incorporate agentic AI attack scenarios into their threat models for retail and payment infrastructure, saying the capability is already commoditized and in active use against the retail sector.

AI agents managing user finances is not entirely new. In August, German bank Scalable Capital opened its platform to AI models like ChatGPT, Claude and Grok. JPMorgan's move complicates the market strategy for AI agents meant to help with personal finances, including Meta's Muse, which launched in September and can connect financial accounts through an integration with Plaid.
