The national average price for diesel in the United States reached a new record of $5.85 per gallon as of September 4, surpassing the previous high of $5.8159 set in June 2022, according to AAA data cited by both sources [1][2]. The price rose from $5.7832 on Thursday to $5.85 on Friday, with the month-ago average at $5.3715 and the year-ago average at $3.7121 [1]. This surge in diesel prices has been attributed to ongoing conflicts in Iran and Ukraine, as well as a global refinery shortage and heightened seasonal demand [2].
According to both articles, the escalation of the Iran conflict in late February triggered a months-long rise in diesel prices, which has been further sustained by the intensification of the war between Russia and Ukraine [1][2]. Ukrainian drone strikes on Russian oil refineries have reduced Russia's diesel production, prompting Russia to extend a diesel export ban through the end of September due to concerns over domestic supply shortages [2]. As a result, global diesel reserves have become critically low, and the abrupt reduction in Russian exports has benefited U.S. refiners, whose diesel exports reached an all-time high last month [2].
Diesel's role as the primary fuel for freight transport means that higher prices are likely to be passed on to consumers through increased costs for shipped goods [1][2]. Democratic Sen. Mark Kelly of Arizona emphasized that diesel powers supply chains and food production, warning that higher diesel costs ultimately make food more expensive for consumers [1]. Joseph Brusuelas, chief economist at RSM U.S., stated that transportation companies are unlikely to absorb all of these cost increases, and consumers should expect higher inflation for any goods requiring shipping [2]. The cost of groceries is expected to be particularly affected, potentially reversing recent trends of stabilizing food inflation [2].
Seasonal factors are also contributing to the price surge, as farmers worldwide rely on diesel for harvesting and planting, and colder temperatures in the Northern Hemisphere are increasing demand for refined distillate fuels, including diesel [2]. The AAA national average price for regular gasoline was $4.1474 as of Friday, compared to $3.2016 a year ago, with the highest recorded average for regular gas being $5.0165 in June 2022 [1].
CONCLUSION
Diesel prices in the U.S. have reached unprecedented levels due to the combined effects of geopolitical conflicts, supply disruptions, and seasonal demand. These record-high prices are expected to drive up costs across supply chains, particularly impacting food and consumer goods. Market participants and consumers alike should brace for continued inflationary pressures as diesel supply remains constrained.
