Bank of England governor Andrew Bailey warns that artificial intelligence used in trading could pose risks to financial markets. Bailey says investment banks, hedge funds, and other financial institutions should “think very carefully” before deploying AI tools. He cautions that the technology may produce harmful or unreliable behavior rather than acting in a manner consistent with market stability and good conduct. The warning is framed as a prudential concern about how AI systems are developed, tested, and supervised when they are used in high-speed, high-stakes trading environments. Bailey’s comments emphasize the need for careful consideration by market participants, implying that governance, oversight, and risk management should match the potential scale and impact of AI-driven strategies. While the outlets report Bailey’s concerns in strong terms, they consistently describe him urging caution around the rollout of AI trading capabilities and highlighting the possibility that such tools could create market disruption if not appropriately controlled.
