The International Monetary Fund on Thursday issued a stark warning that artificial intelligence-powered cyberattacks pose mounting risks to global financial stability, cautioning that defenses “will inevitably be breached” and urging policymakers to treat cybersecurity as a core financial stability issue.
AI Models “Dramatically Reduce” Attack Costs
In a blog post published May 7, the IMF said advanced AI models can “dramatically reduce the time and cost needed to identify and exploit vulnerabilities,” raising the likelihood of attackers simultaneously discovering and targeting weaknesses in widely used systems. The fund warned that extreme cyber-incident losses “could trigger funding strains, raise solvency concerns, and disrupt broader markets”.
The report specifically cited Anthropic’s controlled release of its Claude Mythos Preview model as an illustration of how quickly risks are escalating. The IMF noted that Mythos “could find and exploit vulnerabilities in every major operating system and web browser—even when used by non-experts,” foreshadowing how AI-driven cyber risks could destabilize the financial system if not managed carefully.
Systemic Risks and Emerging Economy Exposure
The IMF stressed that cyber risk is “increasingly about correlated failures that could disrupt financial intermediation, payments, and confidence at the systemic level”. Reliance on a small number of software platforms, cloud providers, or AI models “increases the impact of any single exploited weakness,” the report said.
The fund warned that emerging and developing economies, “which often have more severe resource constraints, may be disproportionately exposed to attackers targeting regions with weaker defenses”. It called for stronger international coordination, more information sharing, and expanded capacity development to preserve global financial stability.
Calls for Policy Action
Thursday’s report follows weeks of escalating concern among global financial authorities. IMF Managing Director Kristalina Georgieva warned in April that the world does not “have the ability to protect the international monetary system against massive cyber risks,” telling CBS News that “time is not our friend on this one”. Her remarks came after Federal Reserve Chair Jerome Powell and Treasury Secretary Scott Bessent held an emergency meeting with Wall Street leaders to discuss the cybersecurity risks posed by the Mythos model.
The IMF advocated for cyber stress testing, scenario analysis, and board-level oversight of cyber threats as “essential” measures, alongside improved public-private collaboration on threat intelligence and incident response. “As AI reshapes the cyber landscape, the central question for authorities is whether the financial system can continue to function under severe stress,” the report concluded.
