Minnesota Trucking Contracts as Diesel Tops $6 a Gallon, Raising Consumer Price Risks
3 articles · Updated · MPR News · Sep 21
Summary
Minnesota diesel prices have climbed above $6 a gallon to record highs, pushing some trucking firms to cut trucks, lose drivers or shut down, according to the state trucking association.
More than $2 of that increase came after the U.S. war in Iran began in March and after Ukrainian strikes on Russian oil refineries, extending a national diesel surge that recently hit $6.51 a gallon.
Volk Transfer said a typical 200-240 gallon fill-up now costs more than $1,200, while smaller carriers said customer rate hikes still do not fully cover fuel bills.
MnDOT said its 850 diesel plow trucks burn 75,000-80,000 gallons a month in warmer seasons and 150,000-160,000 in winter, leaving little short-term relief beyond tighter routing and fuel-saving habits.
Industry leaders said trucking will keep moving freight, but sustained diesel at $6 or more will keep reshaping fleet economics and pass higher transportation costs through to consumers.

With refineries maxed out and inventories at historic lows, what hidden triggers could push diesel prices even higher this winter?
Unprecedented Diesel Price Surge in September 2026: Geopolitical Conflict, Supply Chain Chaos, and Economic Consequences
Overview
The September 2026 diesel price surge was triggered by joint U.S. and Israeli missile strikes on Iran, which led Iran to restrict oil flows through the Strait of Hormuz. This caused over two billion barrels of oil shipments to be disrupted, and diesel exports from the Persian Gulf dropped sharply. The crisis deepened as Ukrainian drone attacks knocked out a quarter of Russia’s refining capacity, prompting Russia to ban diesel exports. These combined disruptions left global inventories tight and pushed U.S. diesel prices to record highs, while severe weather also caused refinery shutdowns in the Midwest, leading to sharp regional price spikes and widespread economic strain.
