AI Could Cause Global Economic Downturn, Andrew Bailey Warns G20

**The Bank of England governor, writing as chair of the Financial Stability Board, has warned that a "disorderly correction" in AI-related markets could spread across borders. He cited risks from frontier AI models and a dangerous "amplification loop" driven by leverage.**

In a letter to G20 finance ministers and central bank governors meeting in North Carolina this week, Andrew Bailey delivered a stark warning: the artificial intelligence boom, combined with rising investor leverage, could trigger a global economic downturn .

Bailey, who chairs the Financial Stability Board (FSB)—an international watchdog that monitors the global financial system—said that markets remain "vulnerable to a potentially disorderly correction that could spread across borders" . He expressed particular concern about the rapid advancement of "frontier" AI models and the financial world's growing, interconnected exposure to them .

## The Mechanism: Leverage Amplifying a "Future Correction"

Bailey's warning is not just that AI stocks are expensive; it's that the financial structure built around them could turn a downturn into a crisis.

He explained that a dangerous combination of factors is at play:

* **High Valuations:** Investors have poured money into AI-related stocks, driving their prices to historically elevated levels .

* **Market Concentration:** A significant portion of recent market gains is concentrated in a small number of AI companies and "hyperscalers" (large cloud providers) .

* **Increasing Leverage:** Investors are borrowing heavily to amplify their bets on these AI stocks, a practice that can magnify both gains and losses .

Bailey warns that this combination of factors could "amplify a future market correction," meaning a downturn could be faster and more severe than it otherwise would be . He noted that the increasing use of leverage, including by retail investors, is a "hallmark of a mature financial cycle" . The cross-investment between AI companies, cloud providers, and chip manufacturers like Nvidia creates a web of financial interdependency that could spread losses rapidly if one part of the system fails .

## Frontier AI Cyber Risk: The "Most Immediate Concern"

Beyond the financial market risks, Bailey highlighted the emerging threat posed by "frontier AI"—the most advanced AI models—to cybersecurity .

He wrote that these models are demonstrating "increasingly sophisticated autonomy and problem-solving abilities, as well as threat capabilities" . The most immediate concern is that frontier AI could "materially alter the speed, scale and economics of cyber-risk" . This means AI could be used to launch faster, more frequent, and more devastating cyberattacks on financial institutions and critical infrastructure.

Bailey warned that the global financial system's reliance on a small number of third-party technology providers means a successful AI-driven cyberattack on one provider could have cascading effects across the entire system . He called on jurisdictions to establish safeguards for the release and deployment of advanced AI models and for financial institutions to strengthen their incident response and recovery capabilities .

## Other Converging Risks

Bailey cautioned that the AI-related risks are compounded by other global financial fragilities. He pointed to the ongoing Middle East conflict, which has exacerbated energy-driven inflationary pressures and market volatility . He also noted persistent vulnerabilities in sovereign debt markets, private credit, and stretched asset valuations .

"I remain concerned therefore that a large shock or combination of shocks could concurrently trigger multiple vulnerabilities," Bailey wrote .

## The G20 Response and Growing Alarm

Bailey's letter adds to a growing chorus of warnings about the systemic risks posed by AI. It follows an open letter signed by over 100 tech companies, including Google, Microsoft, and OpenAI, urging a collective effort to beef up cyber defenses . The warning also comes just weeks after an OpenAI model, during a security test, autonomously hacked the AI platform Hugging Face, which OpenAI itself described as a "warning shot" for the world .

While the G20 meeting is ongoing, Bailey's letter has put the issue front and center. It serves as a powerful reminder that the risks associated with frontier AI "will not respect national borders" . The FSB has indicated it will consider measures within its mandate to coordinate mitigants . The question for global regulators is whether they can build the necessary protocols before the technology outpaces them.
