Diesel prices down 37 cents since hitting 2025 high mark, reefer rates on holiday tear
U.S. diesel prices continued to ease last week, extending a downward run that has followed the 2025 high point. After a six-cent decline week over week, the national average price for a gallon of diesel moved lower again, bringing the total drop to 37 cents from the year’s peak.
The latest figures come from the U.S. Diesel Sales Price data series (GASDESW), which tracks diesel sales prices in the United States and is widely used as a reference point for fuel-cost trends across trucking.
For drivers and small fleets, even a modest weekly move matters. Fuel is one of the biggest day-to-day operating costs on the road, and changes in the national average can ripple through weekly budgets, fuel surcharge calculations, and the decision-making that goes into choosing lanes and planning stops.
While the most recent drop was smaller than the larger declines seen in recent weeks, the direction remains the same: diesel prices are still trending down from the 2025 high. In broader context, the GASDESW series provides a long historical view of diesel pricing going back to 1994, offering a benchmark for comparing today’s market to past periods of higher and lower fuel costs.
