Summary:

• Bank of England Governor Andrew Bailey warned heavy AI investment could contribute to future financial market shocks.

• Bailey said markets currently place high expectations on AI companies, but warned that not every company will succeed.

• He said AI-related asset prices could undergo a correction and financial systems must remain resilient to potential shocks.

• Nvidia is valued at about $5.5tn, while major technology companies are investing hundreds of billions of dollars in AI.

• Anthropic and OpenAI are preparing potential US stock market listings that could attract further investment into the sector.

• Bailey said AI could strengthen economic growth and improve productivity despite the financial risks surrounding the technology.

• He also warned AI could strengthen cyber attacks by making it easier to identify vulnerabilities in computer systems.

• Bailey called for technology companies to help authorities trace deepfakes and other AI-generated deceptive content.

• The Bank of England is using AI to accelerate analysis supporting interest-rate decisions, although policymakers retain decision-making responsibility.

• His warning came as UK 30-year government bond yields exceeded 6%, their highest level since 1998.

Why this matters: Rapid AI investment could support economic growth but also expose financial markets to losses if current expectations prove too optimistic.

What’s next: The Bank of England will continue monitoring AI investment, financial-market risks and the resilience of the wider financial system.
