The Bank of England has issued a warning regarding the growing risk of “sudden corrections” in global markets, raising alarms about the inflated valuations of significant AI technology firms.

Policymakers expressed that a loss of credibility by the Federal Reserve among global investors could result in a potential “sharp re-risk of US dollar assets,” especially as Donald Trump is continuously criticizing the US Central Bank and undermining its independence.

The persistent excitement and positivity surrounding AI technology have driven valuations higher in recent months, with companies like OpenAI valued at $500 million (£37.2 billion), a stark contrast to $157 billion last October. Another entity, Humanity, has nearly tripled in value from $600 billion in March to $170 billion last month.

Nevertheless, the Bank of England’s Monetary Policy Committee (FPC) warned on Wednesday that: “The risk of sudden market corrections is on the rise.”

“Many indicators suggest that stock market valuations, particularly for tech firms focused on artificial intelligence, are escalating. This makes the stock market highly vulnerable should expectations regarding AI’s impact become overly pessimistic.”

Investors admitted that they have not fully considered these potential risks, cautioning that if any materialize, “a sudden correction could happen,” leading to financial strain for families and businesses alike. The FPC emphasized: “As an open economy with a pivotal financial center, the risk of a global shock affecting the UK financial system is significant.”

Confidence in the AI boom has been shaken recently by research from the Massachusetts Institute of Technology, which revealed that 95% of organizations have gained no returns on their investments in generative AI.

This has sparked worries that stock market valuations may decline if investors become disillusioned with AI technology’s advancement or adoption. The FPC noted this could lead to a reassessment of current expected future revenues.

“The substantial bottlenecks to AI advancement, arising from issues related to power, data, or commodity supply chains, as well as conceptual breakthroughs that alter the necessary AI infrastructure for developing and utilizing powerful AI models, can negatively affect valuations, especially for companies reliant on high levels of AI infrastructure investment where expected revenues are projected.”

The committee further remarked that ongoing threats from the Trump administration towards the US Federal Reserve jeopardize financial stability.

“In the US, there is ongoing discussion regarding the Federal Reserve’s independence. A sudden or significant shift in the perception of the Federal Reserve’s reliability could result in a rapid re-risking of US dollar assets, including the US sovereign debt market, leading to increased volatility, risk premiums, and global uncertainty.”

They noted that this concern would compound the effects of Trump’s trade war, which the FPC asserted has “not yet fully materialized.”
