AI boom could trigger market shocks, Bank of England boss warns

The governor of the Bank of England has warned that massive financial bets on artificial intelligence could spark market shocks, prompting regulators to monitor capital flows into the sector closely.

Speaking to the BBC, Andrew Bailey cautioned that while AI holds significant promise to boost economic growth, the sheer volume of speculative funding creates vulnerabilities for the broader financial system. With investors projecting enormous returns, the valuations of prominent technology companies have surged, driving some into multi-trillion-dollar territory.

Bailey noted that current market pricing implies that nearly every major participant in the sector will succeed. However, he drew historical parallels to earlier technology booms, pointing out that early market leaders such as Netscape were eventually overtaken and forgotten. Because history shows that not every venture prospers, Bailey suggested that asset values could face a downward correction if ambitious expectations fail to materialize.

The central bank chief emphasized that authorities are preparing for potential disruptions and working to ensure the financial infrastructure remains resilient. Massive capital expenditure by established tech giants—including Microsoft, Meta, Alphabet, and Amazon—alongside enormous valuations for hardware suppliers like Nvidia, underscores the scale of the industry's reliance on projected AI profits. Planned public listings by major artificial intelligence firms such as OpenAI and Anthropic are expected to draw even more funding into the market.

Beyond financial instability, Bailey highlighted broader threats posed by advancing technology, specifically cybersecurity vulnerabilities. He observed that AI tools can rapidly uncover weaknesses embedded in widely used operating software, warning that such capabilities could act as dangerous weapons if exploited maliciously.

The governor also cited concerns regarding sophisticated digital fabrications, noting that deceptive synthetic imagery is becoming increasingly difficult to trace. Bailey recalled being directly targeted earlier this year by altered visuals on social media platform X, which falsely showed him in a brawl with political figure Nigel Farage. The central bank has encountered obstacles identifying the origins of such material, leading Bailey to urge technology companies to provide better tracking assistance.

Despite these warnings, Bailey acknowledged practical advantages the technology offers monetary authorities. He said artificial intelligence could accelerate data analysis and analytical processes supporting the Bank of England's rate-setting Monetary Policy Committee, functioning as a valuable aid for human decision-makers rather than determining policy directly.
