Citi restricts AI agents from customer accounts as US banks fear deposit shifts
Citi is restricting AI agents from customer accounts, the FT reports, as JPMorgan's Dimon bans external agents and Jane Fraser points to ARC governance.
Citi is restricting AI agents from accessing customer accounts, according to the Financial Times, whose headline reads "Citi becomes latest US bank to restrict AI agents from accessing accounts." The worry across US banks: autonomous tools could shift deposits without customers' direct control.
The clearest window into Citi's thinking came from CEO Jane Fraser at Sibos 2026 in Miami on September 30. She argued that autonomous agents need rigorous identity verification and authentication before they can execute transactions, whether they act for a customer or for the bank itself. Her centerpiece was ARC, an internal platform introduced in 2026 and mandatory for overseeing all of Citi's internal agents. "You cannot create an agent without going through ARC."
The context: JPMorgan Chase CEO Jamie Dimon went further on the bank's third-quarter earnings call, between October 13 and 15, declaring a total ban on external agents in customer accounts and citing the danger of "rogue agents." Crypto Briefing notes that Citi has not announced an equivalent public blanket ban, and Fraser's public remarks have centered on internal governance. That account does not spell out how the restriction works.
My take: the biggest names in banking are installing velvet ropes for robots, and every rope needs a bouncer. Crypto Briefing points out that platforms like ARC require staff, systems and ongoing monitoring. Even the guest list is expensive. Glorious.

Note the verb: the FT says "restricting," while Crypto Briefing says Citi has not announced a public ban on outside agents. Nothing in the reporting says what was measured or how the block works, only what Fraser said about internal controls.
ARC governs Citi's own agents. If you build a tool that needs an outside agent to touch a Citi account, the reporting names no documented way in, no API, no certification, no price.
