UK diesel prices have reached a record 199.18 pence per litre, or about 3,590 won, surpassing the previous high of 199.09 pence set in June 2022, the RAC said. Reuters reported on the 28th that supply-chain disruptions stemming from the Iran conflict were the primary catalyst. Filling an average family car now costs almost £110, or £31 more than before the conflict began. The RAC attributed the increase to the US-Israeli war on Iran, while international diesel prices have also been driven higher by shrinking global refining capacity, conflicts in the Middle East and Ukraine, and supply disruptions. Prices rose again after U.S. President Donald Trump supported a potential ban on U.S. diesel exports, a development that could leave net importers such as the UK and other European countries with fewer alternatives. The UK imports nearly 55% of the diesel it consumes. Higher fuel costs are increasing transport and logistics expenses across industry and agriculture and adding to inflationary pressure after UK inflation reached a five-month high in August. The RAC said sustained lower oil prices would be needed to reduce pump prices and suggested that the government could ease pressure on drivers by lowering fuel duty further or reducing VAT.
