The DOE/EIA benchmark US diesel price rose 22.2 cents a gallon in the week effective July 31, lifting it to $4.127 a gallon, the highest since March 27. The price has risen 36 cents over four weeks.
Analysts note that a one-week jump of this size is rare and was not tied to a specific news event.
Diesel is a major input to freight and fuel surcharges, so a sharp rise lifts transport costs for feed mills and raises the cost of delivered feed ingredients. The momentum suggests continued upward pressure on diesel and related fuel costs.
