## Key points

- AI concerns drove a sharp sell-off in US technology and chip shares.
- Brent crude reached $113.17 a barrel as geopolitical worries grew.
- Great Britain’s retail sales fell 0.4% in September.

## Summary

Global markets weakened as investors questioned whether high returns from the artificial intelligence boom can last, while geopolitical tensions and concerns about France added to the pressure. The sell-off mattered beyond technology shares: investors moved towards US government bonds, and the developments come as British households and shops show signs of spending less.

In the US, the S&P 500 fell 1.2%, the Nasdaq dropped 2.6% and the Philadelphia semiconductor index lost 6.7%. Japanese and South Korean markets recovered from earlier falls to trade broadly flat; Brent crude rose 4% to $113.17 a barrel, while the US 10-year Treasury yield fell to 4.95%. Great Britain’s retail sales declined 0.4% in September, against a forecast 0.1% fall, with warm weather affecting demand for winter clothes and retailers reporting lower footfall and customer cutbacks.
