Bank of England warns G20 of AI risks to financial stability

First reported

CNBC and The Decoder ran this on , a day before the other 2 sources picked it up.

  • Andrew Bailey, governor of the Bank of England, sent a letter to G20 finance ministers warning that advanced AI models could enable faster and more widespread cyberattacks on interconnected financial systems across borders.
  • Bailey highlighted a second financial risk: AI company valuations remain inflated while investors use borrowed money to speculate, and AI firms are deeply cross-invested with cloud and chip companies, so one major failure could cascade through markets.
