The Iran war has cost American consumers $100 billion in higher energy prices, according to a study by Brown University’s The Watson School of International and Public Affairs. Accordingly, the increase in gasoline and diesel prices has cost the average American household more than $760 since the war began on February 28.

There is still a lot of uncertainty about oil production in the Middle East, which will affect fuel prices in the coming weeks and months, Axios reports.

The Ukraine war is also having a considerable impact on energy prices, as Ukrainian attacks on Russian energy infrastructure are affecting global markets, especially the diesel fuel market. Consumers are facing a longer period of high fuel prices than anyone expected at the start of the war.
