Bank of England Governor Warns AI Market Boom Could Trigger Financial Shocks
Huge capital investments flowing into artificial intelligence have driven corporate valuations to historic highs, but central bankers are preparing for potential market instability. The Governor of the Bank of England warned that financial markets could face severe corrections if current high expectations for commercial returns are not met across the sector.
