A powerful new artificial intelligence model from Anthropic has prompted a coordinated response among top global financial regulators, with authorities in the US, Canada and the UK moving quickly to assess risks and shore up bank defenses against potential cyber threats from the advanced AI technology.

Why it matters

Regulators are increasingly treating the capabilities of advanced AI models like Anthropic's Mythos as a potential systemic risk to the global financial system, as disruptions to major banks could have broader consequences. This marks a shift in regulatory strategy from primarily governing AI use to actively encouraging financial institutions to adopt cutting-edge tools to defend against emerging cyber threats.

The details

The US Treasury Secretary and Federal Reserve Chair summoned Wall Street chiefs to warn that Mythos could enable more sophisticated cyberattacks, encouraging banks to deploy the same technology internally to identify vulnerabilities. In Canada, the Bank of Canada convened major lenders and financial authorities to discuss the cyber security implications, while the Bank of England is preparing to take up the issue in upcoming meetings. Anthropic has restricted the release of Mythos to a small group of firms under a controlled testing program to identify flaws and build safeguards before wider deployment.

  • On April 10, 2026, US Treasury Secretary Scott Bessent and Federal Reserve Chair Jerome Powell met with Wall Street executives.
  • In the days following the US meeting, financial regulators in Canada and the UK also took action to assess the cyber risks from Anthropic's Mythos AI model.

What they’re saying

“We must take the potential cyber threats from advanced AI models like Mythos very seriously. Banks need to be proactive in identifying vulnerabilities and shoring up their defenses.”

— Scott Bessent, US Treasury Secretary

“Anthropic's Mythos model represents a new class of cyber risk that could have systemic implications for the global financial system. Coordinated action is needed to assess and mitigate these threats.”

— Jerome Powell, Chair of the Federal Reserve

What’s next

Regulators in the US, Canada and UK will continue to monitor the situation and work with banks to strengthen their cyber defenses against advanced AI-powered threats. Anthropic will also expand its controlled testing program for Mythos to identify and address vulnerabilities before wider release.

The takeaway

The coordinated response by top global financial regulators to Anthropic's Mythos AI model underscores the growing recognition that advances in artificial intelligence could enable a new breed of sophisticated cyberattacks that pose systemic risks to the stability of the financial system. This marks a shift in regulatory strategy towards a more proactive approach in encouraging banks to adopt cutting-edge tools to defend against emerging cyber threats.
