Bank of England governor warns AI could trigger global economic downturn

Andrew Bailey, governor of the Bank of England, has warned G20 finance ministers that a collapse in AI sector growth could lead to a worldwide market correction. He also cited risks from high valuations, investor borrowing, and energy shocks from the US-Iran war, while UK Chancellor John Healey announced a £100m fund for British AI start-ups.

The governor of the Bank of England, Andrew Bailey, has warned G20 finance ministers that artificial intelligence could cause a global economic downturn and pose a significant cyber security risk to financial systems.

In a letter to finance ministers meeting in North Carolina, Bailey said any collapse of growth in the AI sector could lead to a "future market correction" that spreads worldwide. He warned that markets "remain vulnerable to a potentially disorderly correction that could spread across borders, particularly given fragilities in sovereign debt markets."

Bailey, who is chairman of the Financial Stability Board, an international watchdog, expressed concern about the "volatility" prompted by energy supply shocks caused by the US-Iran war. He said 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."

"I remain concerned therefore that a large shock or combination of shocks could concurrently trigger multiple vulnerabilities," he added.

Bailey also 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." 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.

Separately, Chancellor John Healey announced a £100m fund aimed at backing British AI start-ups. The fund 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.

Ministers want companies to compete for the funding to help tackle challenges like cutting waiting lists in the NHS, improving patient care, and bolstering cybersecurity and defence. Healey said Britain is home to some of the most innovative AI companies in the world, and this government is backing them to start, scale and succeed in the UK.

A UK government spokesperson said the new AI economics institute is working with international partners to build "a stronger shared understanding of how AI is transforming economies around the world." The spokesperson said the institute is the first government-backed body of its kind focused on AI's economic impact.

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.
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.

There is growing concern that AI companies are increasingly developing models that can easily override the safeguarding systems of banks.

What was claimed, and who backed it

AI-extracted; can misattribute a claim — see Methodology.

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status is Contested when two claims on this page negate each other; otherwise it counts the distinct outlets we found asserting that specific claim — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
