Reports say Fed chair Jerome Powell among attenders at meeting in Washington

The US Treasury secretary, Scott Bessent, summoned major American bank chiefs to a meeting in Washington this week amid concerns over the cyber risks posed by Anthropic’s latest AI model, according to reports.

Bosses including the Federal Reserve chair, Jerome Powell, were said to have gathered at the Treasury headquarters for the meeting after the release of the Claude Mythos AI model that Anthropic says poses unprecedented cybersecurity risks.

A recent leak of Claude’s code prompted the startup to release a blogpost at the beginning of the month saying that AI models had surpassed “all but the most skilled humans at finding and exploiting software vulnerabilities”, adding: “The fallout – for economies, public safety, and national security – could be severe.”

This week’s meeting was reportedly called while bank bosses were already in Washington for a lobby group meeting, with a guest list focused on heads of systemically important banks – meaning regulators believe a major disruption to their operations, or their potential collapse, would put financial stability at risk.
