London shares pull back as easing Middle east oil panic trims energy majors

British equities slipped on Thursday, reversing recent gains as falling crude oil prices impacted London's energy-focused companies and ended the FTSE 100's longest winning streak since late May. The index fell 0.5% after its six-day advance the previous day. Energy giants Shell PLC and BP PLC suffered from weakening raw material prices, offsetting strong results from the insurance sector and relief from overnight U.S. corporate earnings.

Companies navigated a mix of corporate earnings reports, industrial production data, and adjustments for ex-dividend dates. Prudential PLC, a major insurance player, dropped 1.2% despite a 8% rise in first-half new business profit to $1.38 billion. Meanwhile, industrial production data highlighted persistent challenges in manufacturing, with British vehicle production declining 11.6% year-over-year in July to 63,655 units, according to the Society of Motor Manufacturers and Traders (SMMT).

The decline was attributed to a 15.9% drop in exports and earlier-than-usual summer maintenance at key assembly plants. Brent crude oil slipped 0.5% to around $87.40 a barrel, continuing a multi-day decline as diplomatic talks between Qatari and Iranian officials in Tehran raised hopes for reopening commercial transit through the Strait of Hormuz.

As industrial data was digested and oil prices stabilized, London's investment desks shifted focus to global central bank signals. Traders held cash in anticipation of Federal Reserve Chair Kevin Warsh's address at the Jackson Hole Economic Policy Symposium on Friday, awaiting insights into future interest rates and liquidity conditions for the coming autumn.
