UK Defers Ban on Russian Oil-Derived Fuel Imports Amid Iran War Supply Pressures

May 20, 2026

Britain on May 20, 2026 deferred a ban on diesel and jet fuel imports refined from Russian crude oil in third countries like India and Turkey, originally announced in October 2025, citing supply pressures from the Iran war that has pushed Brent crude to $109 per barrel—50% higher than pre-war levels. The UK issued a licence until January 2027 allowing these imports as the country faces a structural deficit, with four refineries producing 1 million barrels per day against demand of 1.35 million barrels per day, 61% of which is diesel and jet fuel. The decision drew sharp criticism from Conservative opposition leader Kemi Badenoch and Ukrainian officials who accused Britain of funding Russian military operations, while Prime Minister Keir Starmer defended it as a phased sanctions approach necessitated by Middle East disruptions to the Strait of Hormuz.
