The FTSE 100 rose 0.3% on Friday and was on track for a 1.4% October gain, making it the only major European benchmark in positive territory as surging crude prices supported energy stocks and limited exposure to technology companies cushioned the index from a global tech selloff. Brent crude futures for December rose 2.3% to $117.17 a barrel, while West Texas Intermediate gained 1.8% to $103.80 as renewed concerns about possible U.S. military strikes against Iran raised the risk of disruptions to Middle East oil supplies. Shell climbed nearly 1% and BP rose 1.3% after reporting third-quarter underlying replacement cost profit of $8.46 billion, above the $7.33 billion consensus forecast. Unilever gained 1.5%, while European technology shares fell as investors assessed weak results and heavy data-center spending from Alphabet, Amazon and Intel. The STOXX 600 dropped 0.4%, with ASML Holding and STMicroelectronics among the companies weighing on regional markets. Existing earnings developments also included gains for AstraZeneca and GSK, while NatWest lagged despite profit ahead of estimates. Higher energy costs could complicate further interest-rate easing by the Bank of England and other central banks.
