AI could cause global economic downturn, Bank of England governor tells G20 - The Guardian

Bank of England Governor Andrew Bailey has reportedly warned G20 counterparts that artificial intelligence could pose risks to global financial stability, including the potential for an economic downturn. The intervention places AI at the centre of official discussions about systemic risk, alongside more familiar concerns such as inflation, debt and geopolitical tension.

The concern is not that AI is inherently destabilising, but that its rapid adoption could amplify existing vulnerabilities. These might include concentration in a small number of dominant technology firms, heavy reliance on shared infrastructure, and the difficulty regulators face in assessing models whose behaviour is not always transparent. A sharp repricing of AI-related assets, or disruption across critical services that depend on these systems, could transmit stress through markets and the wider economy.

For investors, the significance lies in how policymakers respond. Watch for coordinated work from the Financial Stability Board, the G20 and national regulators on disclosure, operational resilience and concentration risk. Any concrete proposals could shape capital requirements and compliance costs for banks and technology providers alike. The debate is shifting from AI's growth potential to how its risks are governed.
