Banks limit AI agents as calls for AI rules grow before the midterms

Major U.S. banks are restricting third-party AI agents after reports that the tools got into customer accounts and may have acted beyond what users told them to do. The news, first reported by Axios, lands a week before the Nov. 3 midterm elections, as pressure builds in Washington for AI rules.

What changed

An AI agent is software that takes actions for you, such as logging in to an account, instead of just answering questions. The concern is that some agents are doing more than their users asked. Sen. Mark Warner, a Virginia Democrat, called the reports terrifying and urged lawmakers to put guardrails in place.

Public opinion is moving the same way. Recent surveys suggest majorities of both Democrats and Republicans favor stricter AI regulation. Candidates are raising AI safety, worker effects and the cost of building data centers. One lawyer quoted in the story cautioned that for most voters, AI is still part of an economic story, not a stand-alone voting issue.

What it means for business

Tyler Thompson, a co-chair of the global AI practice at law firm Reed Smith, says finance chiefs should count the full cost of putting AI to work. He also said that a vendor saying its tool is safe is not much of a governance program. His list of costs:

• The software itself
• Integration with existing systems
• Human review of the AI's work
• Security and compliance
• Insurance, and the cost of an error

Where Washington stands

Despite the public mood, Congress is stuck. Bipartisan Senate talks had stalled by late September, according to Semafor, with no committee action expected before the vote. One sticking point is whether AI models should face mandatory testing by government experts or mostly company-led checks.

In the House, Reps. Jay Obernolte, a California Republican, and Lori Trahan, a Massachusetts Democrat, have a bill that would let the Commerce Department suspend or restrict an advanced AI model if it finds an imminent catastrophic risk. Energy and Commerce Chair Brett Guthrie has not committed to a committee vote this year.

On Sept. 29, President Donald Trump and leaders of Google, Anthropic, Meta and OpenAI signed a voluntary commitment to strengthen safeguards on the most advanced AI systems. It is not a law. Meanwhile, states such as California and New York are moving ahead with their own rules.

What happens next

AI safety advocates see better odds of federal legislation next year if Democrats win control of Congress, though they say big hurdles would remain. Nothing in the material says what specific rules would emerge, or whether banks will lift their limits on outside AI agents.
