FTSE 100 Falls Led by AstraZeneca

2026-07-09 07:25 By Agna Gabriel 1 min. read

The FTSE 100 traded lower on Thursday, extending a 1.7% loss in the previous session, amid weakness in healthcare and energy stocks.

AstraZeneca slumped 9% after its gene-silencing drug Wainua, developed with Ionis Pharmaceuticals, failed in a late-stage clinical trial to reduce heart complications in patients with a rare and potentially fatal cardiac disease.

Energy majors also pressured the market, with Shell falling 0.8% and BP losing 1.3% as oil prices reversed earlier gains despite renewed tensions between the US and Iran.

Concerns over the conflict, alongside uncertainty surrounding the durability of the ceasefire, have revived fears that higher energy prices could fuel inflation.

Elsewhere, Severn Trent said trading remained in line with expectations after a strong start to its 2027 financial year.

Meanwhile, the latest RICS survey showed UK house prices continued to decline in June, although the pace of falls eased slightly, suggesting the housing market may be stabilising.
