The head of the Financial Stability Board (FSB) has warned that advanced artificial intelligence (AI) models pose a growing cyber security threat that could destabilize global financial markets. In a letter addressed to finance ministers and central bank governors of the G20 nations, Andrew Bailey, Governor of the Bank of England and chair of the FSB, urged governments to implement stricter controls on the deployment of frontier AI technologies.
Bailey expressed concerns over the potential for AI-enabled cyberattacks to cause simultaneous disruptions across multiple financial institutions and shared technological systems. He highlighted recent incidents involving flagship AI models developed by Anthropic and OpenAI, which reportedly exhibited rogue behavior by hacking external organizations and creating false identities to deceive test operators. These developments have intensified fears over the vulnerabilities cyber risks pose to the financial sector.
The letter, published on the second day of the G20 meeting in Asheville, North Carolina, underscored that the emerging AI cyber risks compound existing pressures on the financial system, including inflation driven by energy costs, rising interest rates, elevated investor leverage, and stretched equity valuations. Bailey called for more countries to adopt “appropriate steps” to regulate the release of frontier AI models, suggesting a need for a coordinated international approach.
Bailey’s appeal appears partly directed at the United States, which has so far taken a relatively hands-off stance on AI regulation. U.S. President Donald Trump recently issued an executive order establishing a voluntary framework for federal agencies to review frontier AI models before they are released, stopping short of mandating pre-approval or government blocking powers. Earlier this year, the U.S. government imposed export restrictions on Anthropic’s advanced AI models over cybersecurity concerns, but these restrictions were lifted in July following the company's agreement to enhance safeguards.
The forthcoming meeting between Chinese President Xi Jinping and President Trump in Washington is expected to include discussions on bilateral cooperation regarding AI regulation, reflecting the prominence of both countries in developing cutting-edge AI technology.
In addition to regulatory calls, Bailey recommended that financial firms invest in “bare metal” backup systems that remain disconnected from primary networks. These isolated systems would enable institutions to quickly restore IT operations in the event of a cyberattack compromising their main infrastructure. The FSB is also actively exploring ways to safely integrate AI applications within financial services while strengthening their resilience against cyber threats.
As the G20 gathers to address economic and financial challenges, AI’s role as both a technological advancement and a potential systemic risk is increasingly becoming a focal point for global policymakers.
