UK Inflation Climbs to 3.1% in August Amid Fuel Shock

On September 16, 2026, the Office for National Statistics (ONS) reported that the Consumer Prices Index (CPI) rose to 3.1 % in the 12 months to August, up from 2.9 % in July. The increase marked the highest headline rate in five months and pushed inflation further from the Bank of England’s 2 % target. The ONS identified sharply higher motor-fuel prices and rising airfares as the primary drivers.

The surge follows the Iran war that began in early 2026, which has kept global crude oil above $100 per barrel and disrupted supply through the Strait of Hormuz. The conflict has lifted motor-fuel costs across the UK, a net energy importer, and fed through to transport-related goods and services. Earlier in the year, the Bank of England (BoE) cut its policy rate to 3.75 % after a period of higher rates, but the latest data revive concerns about a possible return to higher borrowing costs.

The convergence of a sharp, energy-driven inflation spike and a still-soft labour market creates a narrow window for policy action. While core and services inflation remain stable, high fuel prices keep the BoE’s options open, and the upcoming budget will need to balance targeted relief with rising borrowing costs.
