Fuel prices changes after the start of the Iran war

The page shows the magnitude of price changes for world average fuel prices and prices in individual countries since February 23, 2026, our last weekly data point before the start of the war in Iran.




Typically, prices in countries with liberalized fuel markets adjust more rapidly. It usually takes a couple of weeks for retail prices to respond to an oil price shock. The effect tends to be larger in countries with lower excise taxes, such as the United States, compared to countries with higher excise taxes, as in much of Europe. Governments in countries with regulated prices often wait several weeks to determine whether the oil price change is permanent before adjusting retail prices. If the shock is large, governments may also intervene to suppress a price increase.
