UK Stock Markets React to Middle East Tensions and Oil Price Surge

On Monday, UK stock indexes experienced broad losses as fears of a breakdown in the U.S.-Iran ceasefire shook investor confidence. The unresolved situation halted traffic through the critical Strait of Hormuz, driving crude oil prices over 5% higher.

The FTSE 100 index declined 0.6%, and the FTSE 250 saw a sharper drop of 1.2%. Among the hardest hit were banks, with Barclays down 2.2% and HSBC dipping 1.1%, pushing the broader banks index 1.7% lower. Precious metals miners also faced setbacks, tracking declines in gold and silver prices.

Conversely, oil companies like BP and Shell rose over 2%, reflecting the surge in oil prices. Meanwhile, luxury brand Mulberry and engineering firm Renishaw reported gains following positive fiscal news. Investors continue monitoring political developments, particularly as Prime Minister Keir Starmer deals with calls to resign over an appointment decision.
