Bank of England Chief Warns AI Valuations and Leverage Could Threaten Financial Stability

AI valuations move from market concern to financial-stability warning

AI valuations and the debt supporting parts of the technology investment boom are becoming a broader concern for financial policymakers. Bank of England Governor Andrew Bailey has warned G20 finance ministers that a sharp reversal in investor confidence could create losses across markets, particularly as AI companies, hyperscalers, lenders and investors become more closely connected.

Bailey's warning combines three risks: prices that may assume very strong future AI growth, increasing use of borrowed money to finance investments, and the possibility that frontier AI systems could introduce new cyber threats to financial institutions. The concern is not that a correction is certain, but that the market's structure could make the consequences more severe if a major participant stumbles.

The Bank of England has described valuations as particularly stretched among companies focused on AI. Its assessment places U.S. equity valuations at levels reminiscent of the period before the dotcom bubble burst, while U.K. share prices are close to their most stretched point since the 2008 global financial crisis.

Concentration and cross-investment raise contagion risks

The U.S. AI sector represents a large share of the country's stock-market value, Bailey said, making the market unusually concentrated. The central bank has also highlighted deeper links between AI firms and credit markets, along with increasing interconnections among the companies themselves.

Those links can create a chain reaction. A decline in the value of one major AI company could weaken investors, lenders and suppliers that have exposure to it. Cross-investments between AI developers and hyperscalers could transmit losses through corporate partnerships and financing arrangements, rather than leaving the impact within a single stock or technology segment.

The Bank of England said losses on lending could increase financial-stability risks if an asset-price correction occurs. It has also warned that risky lending and leveraged activity in other markets are adding to the wider vulnerability of the financial system.

At the same time, Bailey distinguished the current AI boom from the late-1990s technology bubble. He said AI companies have positive cash flows and are not built solely on hope. That does not eliminate the risk of overvaluation, however. The central bank identified disappointing progress in AI capabilities or adoption, as well as stronger competition, as potential triggers for investors to reassess expectations for future earnings.

Spending growth makes the correction question more consequential

The warnings arrive as companies commit substantial resources to AI infrastructure, computing capacity and model development. If expected adoption or profitability fails to match those investments, the financial effects could reach beyond public-market shareholders.

Key pressure points identified by policymakers and market observers include:

  • Equity concentration: AI-linked companies account for a significant portion of U.S. market value.
  • Credit exposure: Growing connections between AI firms and lenders could increase losses during a downturn.
  • Leverage: Borrowed money can magnify both investment returns and forced selling when prices fall.
  • Corporate interdependence: Cross-investments and commercial ties among AI companies and hyperscalers may spread stress.
  • Cybersecurity: More capable frontier AI systems could increase cyber risks to the global financial system.

The International Monetary Fund and the Organization for Economic Co-operation and Development have also warned about the possibility of price corrections. IMF Managing Director Kristalina Georgieva urged investors to “Buckle up,” describing uncertainty as a lasting feature of the economic environment. Investment strategist Joost van Leenders characterized the market as being around stage three of a five-stage bubble framework.

Regulation and resilience remain uneven

The cyber-risk warning adds a policy dimension to the valuation debate. Many countries still lack rules for advanced AI, leaving uncertainty over how model developers, financial institutions and regulators should manage risks from increasingly capable systems.

A market correction would not necessarily become a global financial crisis. The potential damage would depend on the size of the price decline, the amount and distribution of leverage, the resilience of lenders, and how quickly institutions could identify and contain exposures. But the Bank of England's message is that AI should now be assessed as part of the financial system, not only as a technology investment theme.

For AI companies, the warning could increase pressure to demonstrate sustainable cash generation and measurable customer adoption. For investors and lenders, it raises the importance of examining interconnected exposures rather than valuing each company in isolation. For policymakers, it strengthens the case for monitoring AI-related credit, corporate concentration and cyber resilience before a downturn tests those safeguards.
