UK Stock Market Today, 26 November 2025: FTSE 100 and FTSE 250 Rally as Reeves’ Budget Lifts Banks and Miners
London’s FTSE 100 closed up 0.9% at 9,691.58 on Wednesday after Chancellor Rachel Reeves unveiled a tax-raising Autumn Budget, while the FTSE 250 jumped 1.2% to 21,885.52. A technical error at the Office for Budget Responsibility caused a brief sell-off before markets rebounded on the full Budget details. Investors responded positively to pro-equity measures and higher-than-expected fiscal headroom.
