FTSE 100 Slips as UK Inflation Eases, Iran War Lingers

2026-05-20 07:43 By Joana Ferreira 1 min. read

The FTSE 100 slipped 0.3% to 10,300 on Wednesday as investors processed a steeper-than-expected drop in UK inflation while remaining wary of the unresolved Iran conflict.

Headline inflation fell to 2.8% in April, below the 3.0% forecast and the lowest since March 2025, after the energy regulator’s price cap took effect.

Chancellor Rachel Reeves welcomed the data, stating the UK has "the right economic plan" and warning against policy shifts that could destabilize the economy.

However, crude prices remained near four-year highs as stalled US-Iran talks kept inflationary pressures elevated.

Markets now price in just two BOE rate hikes by December, down from nearly three last week, but reversing pre-war easing expectations.

Among individual stocks, Experian fell 4% after announcing a $1 billion buyback and meeting annual guidance, with UK and Ireland underperforming and concerns over AI-related disruptions.

Marks & Spencer rose 2% on higher annual sales and profit growth forecasts.
