Energy traders warn UK diesel stockpiles could run critically low by mid-May if the Iran conflict persists, forcing the government to consider demand restrictions unless prices surge further. A 40% drop in UK diesel imports is predicted if the Strait of Hormuz remains closed for two more weeks, hitting refineries in the Netherlands and Belgium that supply over 40% of UK needs. Prices have risen 34.3p to 176.66p per litre since the conflict began, but retailers are reluctant to pass on wholesale increases, creating market imbalance. Chancellor Reeves has warned against 'profiteering' amid rising inflation fears, while Shell's CEO predicts Europe's energy supply could be curtailed next month.
