U.S. diesel futures surged above $5 a gallon for the first time since 2022, with retail prices hitting a national record of $5.98 per gallon. California drivers pay an average of $7.91 per gallon. Middle East disruptions and Russia's export ban are tightening global refined product supplies.

Diesel typically represents 25 percent or more of trucking operating costs. We project gross margin compression of five to seven percent for long-haul carriers in Q4, creating material downside for pure-play freight stocks. Ryder System Inc. (R), Old Dominion Freight Line Inc. (ODFL), and XPO Logistics Inc. (XPO) face the greatest exposure.

We maintain an Underweight rating on the U.S. trucking sector. Companies with strong fuel hedging strategies or diversified revenue streams are better positioned. However, smaller operators dependent on fixed-price contracts face the most acute risk. Larger carriers may benefit from industry consolidation if prolonged high diesel prices force exits by weaker competitors.

Investors should watch quarterly earnings reports for margin guidance revisions and updated fuel cost assumptions. The Energy Information Administration releases its weekly petroleum status report on Wednesday with updated diesel inventory levels.
