$6 Diesel: America's Hidden War Tax

The recent surge in diesel prices has far-reaching implications for the American economy. On September 11, the national average price of diesel climbed to $6.06 a gallon, up from roughly $3.71 a year earlier, a rise of more than 60 percent.

Diesel is not just a fuel for trucks and cars; it's a crucial component of the country's transportation network. The U.S. Energy Information Administration estimates that about 123 million gallons of distillate fuel were consumed daily in 2025, powering most freight networks, farms, and construction equipment.

The increased cost is not limited to pump prices; it trickles down through supply chains, affecting grocery bills, farm costs, delivery fees, construction bids, and eventually inflation. A recent estimate puts the added burden from the diesel shock at about $46 billion nationwide, or roughly $350 per household.

Washington's policy has inadvertently made the world's most important oil corridor more treacherous. The Strait of Hormuz, a key shipping route, has been repeatedly disrupted since February 28, with only four commodity vessels transiting it on September 14 compared to about 125 prewar average daily transit.

President Trump urged Ukraine to stop targeting Russian diesel infrastructure because those attacks were tightening global fuel supplies. If such actions are unacceptable due to their impact on fuel prices, then the same logic should apply to policies that blockade Iranian exports, sink Iranian tankers, or turn Hormuz into a combat zone.
