Bank of England Warns of Impending AI Bubble Burst and Adjusts Bank Capital Rules

The Bank of England has issued a stern warning regarding a potential “sharp correction” in the valuation of major technology companies, particularly those in the artificial intelligence (AI) sector, amidst growing concerns of an AI market bubble. Millenium TV has learned that the central bank’s latest financial stability report highlights share prices in the UK as being at their most stretched since the 2008 global financial crisis, while equity valuations in the United States bear a striking resemblance to those preceding the dotcom bubble collapse.

Valuations are deemed “particularly stretched” for firms concentrated on artificial intelligence. The central bank anticipates that the AI sector’s growth over the next five years will be fueled by trillions of dollars in debt, potentially escalating financial stability risks if company values decline. Industry projections indicate that spending on AI infrastructure could exceed $5 trillion, with a significant portion funded by AI companies themselves, but roughly half sourced externally, predominantly through debt financing.

“Deeper links between AI firms and credit markets, and increasing interconnections between those firms, mean that, should an asset price correction occur, losses on lending could increase financial stability risks,” a Bank of England official stated in the report. This warning echoes previous concerns raised by other financial institutions and prominent banking leaders regarding a serious market correction in the coming years.

Providing historical context, the dotcom boom of the late 1990s saw an optimistic surge in the value of early internet companies before the bubble burst in early 2000, leading to widespread share price collapses, business failures, and job losses. Such market corrections can significantly impact personal savings and pension funds. These fears surrounding an AI-related stock market correction coincide with recent government initiatives encouraging savers to invest in stocks and shares.

In a move aimed at stimulating economic growth and boosting lending, the Bank of England also announced plans to reduce the amount of capital High Street banks are required to hold. This marks the first such reduction since the 2008 financial crisis and follows rigorous stress tests confirming that UK banks could withstand a severe crisis scenario, including a doubling of unemployment, a significant drop in house prices, and a 5% economic contraction. The central bank proposes lowering the benchmark for Tier 1 capital requirements for firms to 13% from the 14% level maintained since 2015, which would still provide lenders with a substantial £60 billion buffer against minimum requirements, ensuring their continued ability to lend to households and businesses.

The central bank additionally noted that global financial stability risks have heightened during 2025 due to geopolitical tensions, international trade disputes, and rising government borrowing costs. Growing tensions between nations specifically increase the potential for cyber-attacks and other disruptive events.

Furthermore, the Bank of England warned that homeowners with fixed-rate mortgages due to expire in the next two years could face an average increase of £64 in their monthly repayments. The typical owner-occupier transitioning from a fixed rate is projected to see an 8% jump in their bills as higher interest rates continue to have an impact. An estimated 3.9 million people, or 43% of mortgage holders, are expected to refinance at higher rates by 2028, though roughly a third may see their monthly payments decrease as interest rates have fallen significantly since a peak in 2022. The Bank of England’s base rate, which influences borrowing costs, has decreased from 5.25% in 2024 to its current 4%.
