Bank of England governor warns AI investment boom poses financial stability risks

The governor of the Bank of England has issued a warning that the rapid expansion of artificial intelligence could precipitate significant shocks to financial markets, urging the United Kingdom to prepare for potential instability. Andrew Bailey stated that the central bank is monitoring the substantial capital flows into the AI sector with intense scrutiny. He cautioned that while the technology holds promise, the current market valuations reflect high expectations that may not be realised for all participants, suggesting that a correction in asset prices is a distinct possibility.

Bailey acknowledged the transformative potential of AI to strengthen economic growth, a development he described as essential for the country. However, he emphasised that this opportunity is accompanied by substantial risks that require careful management. The governor noted that the sheer volume of money invested in and loaned to AI firms over recent years has led to some companies being valued as multi-trillion dollar businesses. He observed that while investment in this sector is natural given its status as a major area of growth, the resulting rise in asset prices indicates that the market is currently pricing in a scenario where all major players succeed. Bailey argued that historical precedent suggests this is unlikely, noting that not every company in a booming sector ultimately thrives.

To illustrate his point, Bailey referenced the history of internet search engines, noting that Google was not the first market leader. He pointed out that Netscape held that position previously but has since disappeared from the market, serving as a reminder that leadership in technology is not permanent. He stated that the Bank of England is prepared for the likelihood of market shocks and is focused on ensuring the financial system remains resilient. The governor highlighted that the current environment sees a large amount of investment flowing into the sector, with major technology companies spending hundreds of billions of dollars on the technology. Additionally, two of the world’s largest AI companies are preparing to sell shares on the US stock market, a move expected to channel further billions into the industry.

Beyond market valuation risks, Bailey identified other vulnerabilities associated with the technology. He warned that AI provides a more powerful method for uncovering software vulnerabilities, which could be exploited for cyber attacks. He described the technology as a potentially powerful weapon if it falls into the wrong hands. The governor also addressed the issue of deepfakes, or AI-generated images and videos that appear authentic. He cited a recent incident in which deepfake images depicting him and a political figure in a physical altercation were promoted on social media. Bailey noted that the Bank has struggled to trace the origin of these fakes and called for assistance from the technology sector to improve traceability and accountability.

Despite these concerns, Bailey highlighted a significant benefit of AI for the Bank of England. He explained that the technology can speed up the analytical work that supports the Monetary Policy Committee, which sets interest rates. He clarified that AI serves as a tool for policymakers rather than a decision-maker, which he viewed as a positive development. This warning comes at a time when government borrowing costs in several major economies, including the UK, US, France, and Japan, have reached their highest levels in decades. The yield on 30-year UK bonds rose above six per cent, its highest level since 1998, while US 10-year bond yields hit 5.34 per cent, their highest since 2002. Analysts noted that while there was no single trigger for these rises, central banks have been raising interest rates to combat inflation, making alternative investments like AI appear more attractive to investors compared to government debt.
