Why are fuel prices rising?
The recent surge is largely attributed to a ‘conflict premium’ impacting global oil markets. The ongoing US-Iran war and an effective blockade of the Strait of Hormuz—a vital transit point for world oil supplies—have severely restricted availability. This has been compounded by Ukrainian strikes on Russian refineries and a Russian ban on diesel exports, which has further squeezed the European market.
