The Bank of England (BoE) has issued a stark warning that artificial intelligence is emerging as a growing threat to financial stability, citing heightened market expectations, rising leverage, and increasing cyber risks linked to the technology. In its half-yearly Financial Stability Report released Tuesday, the central bank highlighted new risks that have become more pronounced since its previous assessment.
AI Expectations and Market Volatility
The BoE noted that current market optimism surrounding AI assumes the technology will achieve widespread profitable adoption, supported by successful infrastructure development and continued access to financing. However, any deterioration in these expectations could trigger broader market instability. “A reassessment of these prospects could trigger a fall in equity prices that might be amplified by high concentration, correlated momentum-driven positions that can exacerbate volatility as markets fall, and increased leverage,” the central bank stated.
Investors have increasingly borrowed to purchase shares, including hedge funds, while AI-related companies have taken on significant debt to finance investments. The BoE warned that the long-term financial sustainability of these companies will depend on their future earnings potential. “Considerations around the future earnings potential for AI-related companies will also be relevant to the sustainability of these companies' debt,” the report added. Limited transparency around how AI-related companies finance themselves could worsen financial stress during periods of market disruption.
Cyber and Operational Risks
Regulators globally have stepped up their focus on AI risks, including cyber and operational threats linked to frontier AI models and increasingly capable agentic AI systems that can operate with limited human intervention. The BoE said it remains unclear whether advances in AI will ultimately provide a greater advantage to cyber attackers or strengthen the capabilities of those defending financial systems. However, the growing use of AI is likely to require financial firms to update their software more frequently, which could improve security but also increase the risk of operational disruption.
This report follows comments by BoE Deputy Governor Sarah Breeden in late June, who signaled for the first time that bespoke regulation for artificial intelligence may be required to address emerging risks from advanced autonomous systems. The European Central Bank has also ordered eurozone banks to submit AI cyber defense plans by October 31, as ECB Orders Eurozone Banks to Submit AI Cyber Defense Plans by October 31.
Broader Financial Stability Context
Despite these new risks, the BoE said Britain's banking system remains resilient. The central bank also outlined proposals aimed at making it easier for banks to reduce the amount of capital they hold after a crisis, allowing them to continue supporting lending across the economy. Earlier concerns over elevated share price valuations, high public debt, and risky private credit lending to businesses remained in place.
Market participants have noted that AI-related stock rallies, such as those seen in chip stocks, may be overdone. For instance, Michael Burry Shorts Micron, Warns AI Chip Rally Is Overdone, while Chip Stocks Rally but Morgan Stanley Warns of Rotation to Hyperscalers. The BoE's warning adds to a growing chorus of caution from regulators and analysts about the potential for AI-driven market disruptions.
