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

The Bank of England has flagged the rapid growth of artificial intelligence as a potential source of market instability, according to the BBC. The warning centres on how concentrated investment in AI-related assets has become, and how quickly sentiment around those assets could shift.

For markets, the relevance lies less in AI's long-term potential than in how that potential is currently priced. When capital piles into a narrow set of themes, valuations can detach from near-term earnings, leaving indices exposed to sharp repricing if expectations cool. Central banks pay attention because such moves can tighten financial conditions faster than interest rate policy alone.

What to watch: commentary from the Bank of England and other regulators on concentration risk, the pace of AI capital expenditure relative to revenue, and whether credit markets begin pricing AI exposure differently. None of this predicts a shock — it simply identifies where vulnerabilities may sit.
