The FTSE 100 edged lower on Monday as declines in major consumer stocks, including Unilever and BAT, were partly offset by gains in energy shares. Shell and BP rose alongside higher crude prices. Investor attention remained focused on the US-Iran conflict after reports that the US had struck three Iranian oil tankers following attacks on US warships. Energy Secretary Chris Wright warned that a new nuclear agreement with Tehran may not be reached soon and said Washington could instead focus on eliminating Iran’s nuclear capabilities. Separately, UK house prices fell 0.2% in August, pushing annual prices into negative territory for the first time since November 2023, according to Lloyds.
