US Farmers Face Record Diesel Costs Amid Iran Conflict
A recent analysis by the Joint Economic Committee Minority found that American farmers saw a significant increase in seasonal planting diesel costs during the 2026 planting season. According to the report, nationwide diesel costs for planting corn, soybeans, wheat, cotton, and rice increased by 63.2% compared to the previous year.
The largest overall increase in planting diesel costs was seen in Illinois, with an estimated $163.2 million more spent on diesel during the 2026 season than in 2025. Florida led the country in percentage increase at 90.6%, followed by Alabama and Oklahoma.
The analysis estimates that farmers paid an average of $1,538 more to refill a typical 750-gallon on-farm fuel tank, $205 more to fill a grain truck, and $250 more to fill a tractor during the peak diesel prices of the 2026 planting season.
The increased costs are attributed to higher fuel prices following the Trump administration's military strikes on Iran. The conflict has created uncertainty in the oil markets and threatens global fuel prices.
