Jamie Dimon has drawn a line in front of the AI agent gold rush — and it runs through your bank account.

The JPMorgan Chase chief executive said on the bank's third-quarter earnings call on October 13 that the bank will not allow external AI agents to operate inside customer accounts. The restriction blocks assistants such as Meta's Muse and Spear Street Technology's Instinct, CNBC reported.

"We're not going to allow just any … outside agent to come in inside the company, because it's just too risky for clients and for JPMorgan," Dimon told analysts. "You don't want rogue agents, and it could be thousands of them."

Read-only, never move money

The mechanics of the block are narrow but firm. A JPMorgan spokeswoman confirmed that external AI agents are blocked from acting on behalf of retail customers. "Because it is not safe, we do not permit third parties to access accounts by obtaining customers' banking credentials and logging in on their behalf," she said.

Agents can still see some account data — balances, for example — on a read-only basis through open-banking connectors such as Plaid. What they cannot do is the transactional stuff that makes agents useful: sending money, paying bills. The bank gave no timeline for loosening the rule.

The worry is straightforward. An agent acting for a customer can cancel a subscription, buy a product, or transfer funds — and a manipulated or confused agent could send money somewhere the customer never intended.

The "liability transfer" warning

Dimon framed the policy as a question of who carries the loss. "If people are using them, they should understand the risk," he said on the call. "They should understand there's a liability transfer."

The bank, in other words, won't be on the hook when an outside agent misfires. If your agent moves $10,000 between accounts based on a misunderstood prompt, that's on you, not Chase.

It's a stance other banks are starting to echo. The Financial Times reported on October 16 that Citi has followed JPMorgan's lead. Citi said on October 13 that an AI coding tool used by 14,000 of its engineers lets it bring more work in-house — "we have reduced our tech vendor spend by 30% year over year" — and Mizuho will start retraining sales and office staff as AI developers next month, Nikkei reported.

The bank is building its own agent

None of this means JPMorgan is against AI agents — it just wants them to be its own. CFO Jeremy Barnum said on the same call that the bank has begun a targeted pilot of Smart Cash, an internal AI tool that predicts a customer's cash flow and moves funds to maximize yield.

That's essentially what Muse and Instinct promise to do from the outside. JPMorgan is blocking external agents from offering the service while building its own version of the same thing.

The wider industry is watching. Amazon blocked Meta's Muse agent from its marketplace in September, saying the agent appeared to capture and store customer credentials, and PYMNTS Intelligence data shows only 35% of consumers would let an agent reach their saved payment credentials. The age of the personal AI agent has arrived — and the gatekeepers are deciding where it's allowed to go.
