The hidden $350 surcharge on American households

Diesel fuel prices in the United States reached an all-time high of $6 per gallon, surpassing the previous record. This surge is largely attributed to the ongoing Iran war, which has effectively closed the Strait of Hormuz, a crucial shipping route for seaborne diesel. The price jump has been particularly steep in states like California, where diesel now costs $7.91 per gallon, a $2.31 increase compared to late February 2023.

The indirect impact of these rising diesel prices is felt by most Americans as they contribute to the costs of goods ranging from milk to lumber, ultimately affecting grocery store prices. In 2022, the Iran war caused diesel prices to peak at $5.82 per gallon. The current surge has resulted in an additional $46 billion cost to US consumers, or about $350 per household, according to a Brown University tracker.

This figure is slightly lower than the impact of rising gasoline prices, which have cost $55 billion, but the 61 percent increase in diesel prices surpasses the 41 percent increase in gas prices. The geopolitical turmoil surrounding the Iran war and Ukraine's attacks on Russian oil refineries has exacerbated this situation. With US refineries operating at full capacity and domestic inventories at their lowest level since 1982, the risk of further price increases is heightened.

This crisis is particularly concerning as it coincides with the approach of winter, during which heating oil, essentially diesel, will be in high demand from millions of households. The administration's consideration of eliminating the Low Income Home Energy Assistance Program adds to the financial burden on vulnerable families.

While it is unlikely that fuel prices will drop immediately, even if the conflicts in Iran and Ukraine were to end, it would take weeks or months for supply to recover and for diesel prices to stabilize.
