The FTSE 100 fell more than 1.5% to 10,432 on Thursday, its lowest level since June 23, as UK equities tracked a wider sell-off across European markets. The decline coincided with rising global bond yields, including a brief move above 6% in the 30-year gilt yield, its first such level since 1998. The increase reflected international pressure, particularly higher yields in France and the US, rather than developments in UK domestic politics. Banks led the declines: HSBC fell more than 4%, Lloyds dropped 4.4%, NatWest lost 5.2%, Barclays declined 3.8% and Standard Chartered fell 3.2%. AstraZeneca and GSK dropped 1.8% and 1.6%, respectively, while Unilever fell 2.4% and BAT lost 3.4%. Mining stocks also weakened, led by Rio Tinto and Glencore. Energy shares moved against the broader trend, with Shell and BP gaining as oil prices rose. Nationwide reported that UK house prices fell 0.2% in September, slowing annual growth to 0.8%, the weakest pace this year.
