Bank of England Flags Financial Risks Amid AI Boom, Hedge Fund Leverage

Key Takeaways:

• Warnings about overvaluation of AI companies and its potential impact on financial stability.
• Concerns over high-risk lending to large corporations and increasing linkages between AI and credit markets.
• Highlighting hedge fund leveraged bets in the gilt (government bond) market.
• Reassurance that UK banking system remains well-capitalized, but external risks are mounting.

Bank of England Raises Alert on Financial Risks

The Bank of England (BoE) on Tuesday flagged increasing risks to the UK financial system by 2025, citing overvalued artificial intelligence (AI) companies, high-risk lending to large corporations, and leveraged bets in the government bond market.

These comments, contained in its bi-annual Financial Stability Report, build upon warnings issued by BoE Governor Andrew Bailey and other policymakers in recent months, although the report also announced the first cut to UK bank capital requirements since the 2008 global financial crisis.

The BoE believes that the UK banking sector is well-capitalized and overall debt levels for domestic firms and households remain relatively low. However, it sees risks emanating from overseas and other areas of financial markets.

"Financial stability risks are set to increase through 2025," the BoE stated. "Global risks remain elevated, with significant uncertainty around the global macroeconomic outlook. Key sources of risk include geopolitical tensions, trade and financial market fragmentation, and sovereign debt market pressures."

Warnings About Overvalued AI Stocks

The BoE estimates that investor enthusiasm for AI has pushed US stock valuations to their highest levels since the dot-com bubble and to their highest in the UK since the global financial crisis.

"Deeper linkages between AI firms and credit markets, and increasing interconnectedness between these firms, mean that loan losses could amplify financial stability risks in the event of an asset price correction," the BoE said.

The central bank also noted the collapses of US auto parts manufacturer First Brands and car dealer and lender Tricolor, events Bailey flagged in October as potentially a warning of bigger problems to come.

The BoE plans to conduct a stress test on the resilience of the private market ecosystem, with more details to be released later this week.

Hedge Funds Place Multi-Billion Pound Leveraged Bets on Gilt Market

The BoE also highlighted that hedge fund leveraged borrowing in the gilt repo market was close to 100 billion pounds ($132 billion) last month, driven mainly by a small number of hedge funds.

"This reinforces the need for market participants to ensure that risk management of their positions takes account of potential shocks, including shifts in correlations beyond historical norms," the BoE said.

The central bank believes the fundamentals of the UK gilt market are more robust now than a few years ago, thanks to the bond market crash after then-Prime Minister Liz Truss's budget proposals and steps taken to shore up liability-driven investment funds.

Despite this, Jon Hall, an external member of the Financial Policy Committee, stated in October that the preparedness of some non-bank financial institutions for future shocks remains limited.

Hall suggested that a repeat of the 2008 financial crisis was possible, where the public had to step in to bail out banks to avert a larger financial meltdown.

In 2022, the BoE purchased 19.3 billion pounds of UK government debt due to a sharp fall in bond prices triggered by Truss's budget proposal.

Investors and hedge fund sources told Reuters earlier this year that the influx of hedge funds into leveraged bets on UK government bonds was partly driven by activity in the short-term lending market.
