Ultra-low sulfur diesel contracts on the CME declined 3.93% over three consecutive trading days ending Monday, settling at $3.8772 per gallon—the lowest level since mid-July. The benchmark Department of Energy retail diesel price, which underpins most fuel surcharges, rose this week, marking the fourth consecutive weekly increase and a 77-cent gain over that period. The disconnect between falling futures prices and rising retail rates reflects the complexity of fuel pricing. Station owners—not integrated oil companies—ultimately control pump prices. Fully integrated producers set wholesale rack prices daily based on market conditions, but lack direct control over final consumer prices.
