What moved markets
- London’s blue-chip index lost 1.7% and the FTSE 250 fell 1.6%, a broad sell-off across UK equities in the first session of October.
- Brent crude dropped 2.2% to $101.25 a barrel, its softest level in this data series snapshot, while gold edged up 0.1% to $4,192.30 an ounce as investors hedged.
- The pound weakened against both the dollar (-0.3% to $1.32) and the euro (EUR/GBP -0.7% to €0.85), which partly cushions the FTSE fall for overseas earners but raises import costs.
- One reported backdrop: the Bank of England governor warned the AI investment boom could trigger market shocks, though the data alone does not confirm this drove today’s selling.
