Synopsis
The Bank of England is actively assessing artificial intelligence risks to the financial system. They are conducting simulations and working with global partners to understand AI's impact on trading. This proactive approach aims to address potential market stress. Meanwhile, the Treasury Committee urges faster action on regulating critical AI and cloud firms.Listen to this article in summarized format
The BoE said it disagreed with an assessment by parliament's Treasury Committee that it was taking a "wait-and-see" approach to the risks presented by AI, and that it was analysing how AI investment and adoption were changing the financial system.
It is also working with international counterparts to understand how AI agents might affect trading in financial markets, BoE Deputy Governor for Financial Stability Sarah Breeden said in a letter to the Treasury Committee.
Testing will focus on "herding" behaviour that could amplify selloffs during periods of market stress, Breeden said.
AI risks in the financial system came into sharper focus last week with the launch of Anthropic's Mythos product. Experts say its powerful coding ability could offer new ways to find cybersecurity vulnerabilities and exploit them.
BoE Governor Andrew Bailey said Anthropic may have "found a way to crack the whole cyber risk world open".
The Treasury Committee criticised Britain's finance ministry for failing to commit to bringing major AI and cloud companies into the Critical Third Parties (CTP) Regime - which regulates key financial system infrastructure suppliers - before the end of 2026.
"I am pleased to see the Bank of England is grasping the nettle to some extent but I remain perplexed at the apparent inertia shown by the Treasury," Treasury Committee Chair Meg Hillier, a member of the governing Labour Party, said.
"The powers offered by the Critical Third Parties Regime are sitting unused while we remain vulnerable. I simply cannot understand why this is taking so long. We will continue to monitor this situation closely."
Treasury minister Lucy Rigby told the committee that the government expects to make initial CTP designation decisions this year, but would not reveal which firms are under consideration in order to protect the integrity of the process.
The BoE's Financial Policy Committee on April 1 said firms have yet to deploy advanced AI such as agentic tools in ways that pose systemic risk, but warned that those risks could rise rapidly as the financial sector steps up adoption.
