Financial Stability Board warns G20 that intertwining AI financing with cloud giants threatens a cross-border market shake

International Financial Stability Board chairman and Bank of England governor Andrew Bailey issued a direct warning to G20 finance ministers that the AI sector now carries, in its financial and operational structure, seeds of a global economic slowdown and severe cyber-security risks that threaten the international financial system. In an open letter, Bailey explained that any stumble or collapse in the AI sector's growth pace could lead to a broad market correction with worldwide impact, urging companies to prepare for security breaches that could cause simultaneous disruptions affecting multiple institutions at once.

This financial warning is based on the convergence of three risky factors:Elevated valuations of financial market stocks, rising borrowing and leverage levels among investors, and liquidity concentration in a limited number of major technology firmsBailey noted that the danger does not lie in borrowing alone, but in the interaction of this leverage with inflated valuations and market concentration, specifically the reciprocal and escalating investment between AI model companies and massive cloud-infrastructure providers, which could amplify any forthcoming market correction.

These concerns coincide with rising regulatory worries about modern AI models exceeding banking protection systems in financial hubs. Recently, major tech firms such as OpenAI, Anthropic, and Meta disclosed unexpected behaviors by their tools and AI agents, including instances of impersonating real individuals to bypass security hurdles and conceal evidence, prompting a coalition of one hundred tech companies to urge governments to strengthen cyber defenses before the models acquire capabilities that outstrip existing protections.

At the national policy level, this international move comes as governments such as Britain, via a fund for start-ups and an institute for AI economics, aim to build sovereign capabilities to avoid full reliance on foreign services and to secure public services and cyber defence. However, Bailey, who leads the Financial Stability Board composed of finance ministry officials, central banks and securities regulators from countries including Saudi Arabia, the United States, the United Kingdom, France, Germany, China and Japan, calls for clear standards that ensure the safe and responsible global deployment of models, alongside the volatility in international energy markets caused by the war between the United States and Iran.

This warning shifts AI risks from purely technical debate to banking and investment risk registers in the regionSaudi Arabia’s presence on the Financial Stability Board, together with the scale of assets managed by sovereign wealth funds and central banks in the Gulf, means that compliance, investment and risk-management officials at Gulf and Egyptian banks are now required to reassess their exposure to inflated technology valuations and dependence chains on major cloud providers. It also obliges Arab financial institutions to audit their internal cyber defenses against independent model agents and ensure that infrastructure and computing investment deals account for the possibility of sudden price corrections and global energy volatility.

Building advanced cyber and banking defenses is no longer a regulatory luxury; it has become a prerequisite for safeguarding financial stability in an international environment where AI algorithms intertwine with major global capital markets.
