GoKawiilThe governor of the Bank of England has warned G20 finance ministers that artificial intelligence could cause a global economic downturn and pose a significant cyber security risk to financial systems.
Andrew Bailey said any collapse of growth in the AI sector could lead to a "future market correction" that spreads worldwide.
In an open letter to finance ministers in the US on Monday, he said companies around the world should prepare for security breaches "involving simultaneous disruption across multiple firms".
Earlier this month, a group of 100 firms, including Google, Microsoft, Anthropic and OpenAI, urged countries and groups to beef up their cyber defences before AI grows powerful enough to override them.
Bailey told the G20 finance ministers that a combination of highly priced stock markets, increased borrowing by investors, and the growing concentration of money into a small number of major technology companies could amplify any future market correction.
"The issue is not simply that investors are borrowing more, but that leverage is interacting with high valuations and market concentration, in particular the increasing cross-investment between artificial intelligence (AI) companies and hyper scalers, in a way that could amplify a future market correction," he said.
Bailey has called on those in charge of financial security to develop "appropriate steps to support safe and responsible model release and deployment on a global basis".
Bailey, who was writing in his capacity as chairman of the Financial Stability Board international watchdog (FSB), expressed concern about the "volatility" prompted by the effect of energy supply shocks caused by the US-Iran war.
His warning comes several months after UK Chancellor John Healey announced a £100m fund aimed at backing British AI start-ups.
That is part of the government's efforts to grow the country's "sovereign AI" capacity, developing homegrown AI technology to ensure the UK is not dependent on services from abroad.
