From 7 May 2026IMF warns AI tools such as Mythos threaten financial stabilityNewsflash: The International Monetary Fund is warning that financial stability risks are rising as artificial intelligence fuels cyber-attacks.In a new blogpost, just published, the IMF singles out Claude Mythos as an example of how quickly risks are increasing.The Fund is calling for “resilience, supervision, and international coordination” to safeguard global financial markets, and protect them against attackers with new AI tools.It warns that AI tools such as Mythos can “dramatically” cut the time and cost needed to identify and exploit vulnerabilities, which raises the risk of weaknesses in key systems being discovered and exploited.IMF experts Tobias Adrian, Tamas Gaidosch and Rangachary Ravikumar write:

This foreshadows how fast‑moving, AI‑driven cyber risks could destabilize the financial system if not managed carefully, and why authorities must focus on building resilience through supervision and coordination—rather than treating these developments as purely technical or operational issues.
