Sarah Breeden, the Bank of England's Deputy Governor for Financial Stability, has warned that the increasing use and concentration of artificial intelligence in financial markets pose a significant risk of "market meltdowns." She specifically noted that asset prices often do not accurately reflect the underlying risks in the market, suggesting a potential for global market declines. Breeden's concerns are exacerbated by what she describes as "herding" behavior among AI models, where these models could collectively amplify market selloffs, destabilizing the financial system more broadly.
Breeden’s comments come amidst broader concerns from the Bank of England regarding AI. The central bank's Financial Policy Committee (FPC) previously warned about the rapid pace of AI adoption, particularly among hedge funds and trading firms. The FPC expressed worry that humans might soon lose full comprehension of these models' operations, potentially leading to unforeseen market instability or manipulation. The FPC also highlighted a scenario where a sudden shift in perceptions about AI's impact could lead to a sharp correction in equity markets, especially given the high valuations of technology companies focused on AI.
The Bank of England is not only issuing warnings but also taking action. It plans to closely monitor AI usage by financial institutions and conduct stress tests to evaluate the risks, particularly focusing on the "herding" behavior of AI. This initiative follows the release of Anthropic’s Mythos AI product, which has raised concerns among experts and Governor Andrew Bailey about its potential to expose cybersecurity vulnerabilities and pose a significant cyber threat to the financial system. The Bank has also criticized the Treasury Committee for a perceived "wait and see" approach to regulating AI and cloud companies under the Critical Third Parties regime, advocating for more proactive measures to mitigate these emerging risks.
The context of these warnings includes global economic pressures such as the ongoing war in Iran, which has delivered a "substantial negative supply shock" to the global economy, contributing to inflation and tighter financial conditions. The FPC has also pointed out that equity market valuations, particularly in the AI-focused technology sector, appear stretched, drawing comparisons to the dot-com bubble. For instance, the five largest companies make up 30% of the S&P 500's valuation, representing the greatest concentration in 50 years. This market concentration, combined with AI-driven investor expectations, could lead to a sharp market correction if expectations about AI's impact become less optimistic or if material bottlenecks in AI progress emerge. The Bank also noted vulnerability in US government bonds due to concerns about the Federal Reserve's credibility.
