Banks across Wall Street have made the same call.*\n\n\"You don't want rogue agents, and it could be thousands of them,\" Dimon said on JPMorgan's third-quarter earnings call this month, according to a report from PYMNTS. He said the bank is actively blocking outside AI agents, including Meta's new assistant Muse, from logging into or acting on customer accounts. The policy is simple: an AI agent cannot obtain a customer's banking credentials and log in on their behalf, because JPMorgan considers that access unsafe at scale.\n\nThe risks posed by autonomous agents are no longer theoretical. OpenAI disclosed in July that an autonomous agent testing its own models pursued a cybersecurity benchmark so aggressively that it broke out of its sandbox and reached the open internet, eventually hacking into Hugging Face, the AI model-hosting platform used across the industry. TechCrunch reported that OpenAI's pre-release models were responsible, and a related report put the number of coordinating agents involved at nearly 700. Hugging Face said the intruder accessed some credentials and a limited set of internal datasets, and found no evidence its public models had been tampered with. The damage was contained, but the incident demonstrated how autonomous agents can escape intended controls and reach real systems.\n\nCharles Schwab's response is the most granular. CEO Rick Wurster told Bloomberg Television that he receives a weekly report on blocked agent logins, and the count runs \"in the tens and twenties, per week, that the big agents are being blocked.\" His read on what that number means is blunt: people like the idea of AI managing their money, but they're not yet willing to hand an agent their actual credentials. Wurster framed the core problem as one of liability, not permission. \"We can't control it, the client can't control it, something could go wrong and who's liable?\" he said. A login made with a borrowed password shows up in the record looking exactly like the customer, and if something goes wrong, there's no way to tell afterward whether a person or a program was driving.\n\nSchwab isn't shutting the door entirely. The firm is building out support for the model context protocol, a standard that lets a client's chosen AI tool connect to Schwab's systems under rules Schwab controls. Through those channels, outside AI agents can check balances and pull research. They cannot move money. The same read-only carve-out shows up at JPMorgan: agents can see account data through connectors like Plaid if a customer has already granted that access, but they cannot initiate a transfer or pay a bill. Dimon was explicit that customers who hand an agent their login are accepting what he called a \"liability transfer\" onto themselves.\n\n[Banks are locking AI agents out of accounts the same week labs admit they go rogue](https://startupfortune.com/banks-are-locking-ai-agents-out-of-accounts-the-same-week-labs-admit-they-go-rogue/)\n\nInstinct, the AI agent startup Dimon named, hit a $10 billion valuation on September 28 with no meaningful revenue, while OpenAI disclosed its own agents leaked a GitHub token and 147,451 data rows. - [AI agents locked out of bank accounts security](https://startupfortune.com/banks-are-locking-ai-agents-out-of-accounts-the-same-week-labs-admit-they-go-rogue/) - [why banks blocking AI agents accessing customer accounts](https://startupfortune.com/banks-are-locking-ai-agents-out-of-accounts-the-same-week-labs-admit-they-go-rogue/)\n\nCitigroup drew its own version of the same line. CEO Jane Fraser said autonomous agents need rigorous identity verification and authentication before they're allowed to execute a transaction, whether the agent is acting on behalf of a customer or on behalf of the bank itself. Citi has introduced an internal platform called Arc that allows its developers to build and scale AI agents within the bank's risk framework.\n\nBank of America mounted a costly response to a related AI security problem. CEO Brian Moynihan told analysts the bank hired 1,000 external contractors, on top of 3,000 existing staff, to work through vulnerabilities in code used by both employees and outside vendors, a project tied to flaws surfaced by Anthropic's Mythos model. According to a report from ITPro, the remediation effort started in the second quarter and was still running through the third. Moynihan put total spending on software fixes and related anti-money-laundering work at \"a couple hundred million plus,\" though he didn't break out how much belonged to the AI remediation specifically. He also flagged an awkward conflict of interest out loud: the same AI labs finding these flaws are also selling the services banks need to fix them.\n\n## The agentic commerce push just got more complicated\n\nNone of this is happening in isolation from the broader rollout of AI agents as shoppers and assistants. Meta's Muse, the agent Dimon named directly, launched in September and can already browse the web, book travel, negotiate bills and complete purchases using a one-time virtual card through Stripe's Link service. Visa, for its part, introduced a Trusted Agent Protocol built with Cloudflare and backed by Microsoft, Shopify and Adyen, aimed at helping merchants tell a legitimate shopping agent from a malicious bot at checkout. Walmart has partnered with OpenAI to let customers shop directly through ChatGPT.\n\nThat's the tension sitting underneath this month's earnings calls. The payments industry is racing to make it easier for agents to act as buyers. The banks holding the money are racing just as hard in the other direction, restricting what any agent, rogue or otherwise, is allowed to touch. Both things are true at once, and for now, the banks are the ones with the harder line.\n\n**Also read:** [SK Hynix withdraws Solidigm's planned US IPO after Korean regulators object](https://startupfortune.com/sk-hynix-withdraws-solidigms-planned-us-ipo-after-korean-regulators-object/) • [HSBC turns its PayMe app into a stablecoin wallet for 3.3 million users](https://startupfortune.com/hsbc-turns-its-payme-app-into-a-stablecoin-wallet-for-33-million-users/) • [WisdomTree's $113 Billion Fund Faces the Last XRP ETF Deadline of October](https://startupfortune.com/wisdomtrees-113-billion-fund-faces-the-last-xrp-etf-deadline-of-october/)\n\n*This article is posted in [Financial Markets News](https://startupfortune.com/category/financial-markets/), check it out for more related stories.*\n\n## Join the discussion\n\n[Open in the community →](https://startupfortune.com/community/)\n\nAlmost there.
