Big banks block outside AI agents from customer accounts. Payments firms are defining who authorizes agent-led purchases.

JPMorgan Chase said it will not let outside AI agents directly access retail customer accounts. Citi has also restricted agent access, while Charles Schwab is blocking agents that use client credentials or browser automation.¹²³

The concern is not only fraud or mistaken trades. Banks and brokers also fear that an agent acting for a customer could move idle cash into higher-yielding accounts, weakening a major source of interest income.²³

Several rivals are testing controlled ways to connect customers' preferred agents. Bank of America, BBVA, Synchrony, and Wells Fargo joined the Personal Agent Protocol, while Robinhood and Coinbase already permit certain links between customer accounts and AI assistants.⁴

American Express introduced an Intent Intelligence Framework that it says carries a customer's purchase instructions through an agent-led transaction. The company is seeking to make it an industry standard.⁵

The unsettled issue is liability when an agent makes the wrong purchase, is manipulated, or follows a bad instruction. Federal Reserve Governor Christopher Waller said existing card-network and consumer-protection rules may be adaptable, but could require testing and refinement.⁶

Visa argues that standards developed for online and mobile payments can help protect agent-led payments, and Stripe President John Collison said the processor's agentic-commerce activity rose sharply in September without publishing figures.⁷⁸

U.S. banking regulators are asking banks about advanced models, including their use of Chinese technology, AI in cyber defense, and their ability to control autonomous systems. European supervisors are pressing banks to strengthen recovery plans for AI-related disruption.⁹

The UK Financial Conduct Authority plans to use AI to automate parts of financial regulation.¹⁰

In consumer banking, a report by former regulators argues that banks remain liable when customer-service chatbots give wrong answers, make decisions affecting finances, or prevent customers from reaching help.¹¹

Insurers remain reluctant to let generative AI determine rebuilding costs. Openly's technology chief said cost models need to be transparent and deterministic, while industry participants emphasized that experienced professionals should validate estimates.¹²

Property and casualty insurers asked the National Association of Insurance Commissioners to exclude generalized linear models, widely used in insurance pricing, from its AI evaluation tool. The NAIC plans to finalize that tool at its November 14 to 17 fall meeting.¹³

Colony Bank says generative-AI loan software cut its SBA lending workflow from 92 steps to 32 and reduced approvals to about seven business days for responsive customers. At the other end of the scale, BNY says it is putting AI across its business but declined to disclose its spending or quantify the returns.¹⁴¹⁵
