Bank of England Deputy Governor Sarah Breeden said in Sintra, Portugal, that the central bank is running simulations on how AI-driven trading could amplify volatility if multiple systems try to place similar trades at the same time. The Bank is studying tools such as an AI “kill switch” and enhanced circuit breakers to limit or halt trading across markets if faulty models trigger a meltdown, working with Germany’s Bundesbank and the Bank for International Settlements. The work is tied to a cautious assessment of “agentic” AI becoming embedded in trading systems. The discussions remain at the research and policy stage, with no new rules or implementation timetable announced.
