The International Monetary Fund (IMP) has warned that artificial intelligence is rapidly increasing the threat of cyberattacks on the global financial system, potentially turning localized breaches into economic shocks that could shake markets, freeze payments, and erode confidence in banks worldwide. The IMF highlighted the release of the advanced AI model Claude Mythos Preview, which can identify vulnerabilities across all major operating systems and web browsers. The fund warned that AI may further concentrate risk across the financial system due to its reliance on a small number of cloud providers, software platforms, and AI models. It also highlighted the potential for an international incident involving a single exploited weakness to trigger cascading failures. The IMP urged policymakers to treat cybersecurity as a core financial stability concern rather than technical issues.
