NASHVILLE, TENN. (RFD-TV) — Refining bottlenecks and tight global diesel supplies are keeping farm fuel costs elevated even when crude oil prices ease, adding pressure during one of agriculture’s most fuel-intensive periods.
Dow Jones Energy says 2026 diesel price spikes have been driven primarily by limited refining capacity and middle-distillate availability. Diesel crack spreads exceeded $100 per barrel in key markets as Russian exports fell and Middle Eastern supply disruptions tightened global trade.
U.S. Energy Secretary Chris Wright said refiners are running near capacity and warned that the rapid diesel increase was not built into Midwest farmers’ harvest economics. Combines, tractors, semis, grain dryers and other equipment leave producers with little flexibility to reduce fuel use during harvest.
Higher U.S. diesel exports have also helped replace lost Russian and Middle Eastern supply, increasing competition for finished fuel. Dow Jones says U.S. Gulf Coast exports rose as buyers sought alternative barrels.
The report expects global diesel demand to remain strong through the next decade, keeping farm fuel costs sensitive to refinery outages, geopolitical disruptions, and tight inventories.
