US diesel prices have risen 82.5% nationally since the start of 2026, following the US war on Iran and the partial closure of the Strait of Hormuz, with Russia's war in Ukraine also adding disruption. The US Energy Information Administration says prices may not normalise until 2028 even if the conflicts end, because damaged refining capacity takes time to rebuild.
Prolonged diesel and freight cost inflation raises the cost of moving feed ingredients and grain across the US. Persistent energy costs also support input costs for livestock producers.
