In the United States, diesel futures jumped 7.4% to $4.19 per gallon this week, marking the steepest increase since July. Retail prices have climbed to an average of $5.32 per gallon, a significant leap from the $3.71 recorded just one year ago. As refineries push utilization rates toward 100%, industry experts warn that the system has reached its limit. Exxon, Chevron, and Shell are currently operating at near-maximum capacity, leaving no buffer for maintenance or unexpected disruptions.

The strain is compounded by long-term structural shifts, particularly in Europe, where government decarbonization mandates have led to consistent refinery closures even as fuel demand remains robust. With U.S. diesel inventories at their lowest seasonal levels in three decades, the world's largest exporter has little room to maneuver. Analysts expect these elevated margins to persist through the year, as Russia’s export bans and ongoing instability in the Middle East continue to stifle supply chains. As costs permeate every sector from agriculture to freight, the surge threatens to fuel broader inflationary pressures across global economies.
