The FTSE 100 climbed 1.6% on Tuesday, ending a three-day losing streak as falling oil prices lifted investor sentiment. Crude retreated on expectations that the world’s largest economies could release strategic reserves if necessary, helping to offset supply risks linked to the conflict in Iran. Mining stocks led the gains, with precious metals producer Fresnillo surging more than 7.5% after six consecutive sessions of losses, while Endeavour Mining advanced over 3%. Copper producer Antofagasta also rose more than 6%, alongside Anglo American. Banking stocks posted solid gains as well, with HSBC Holdings, Barclays and Lloyds Banking Group rising between 2% and 5%. Rolls-Royce rebounded strongly, climbing over 5% after dropping more than 9% across the previous three sessions. Housebuilder Persimmon also gained more than 5% after reporting higher annual sales and profits. In contrast, shares of Shell and BP declined as falling oil and gas prices weighed on the sector.
