US diesel crack spread tops $100 a barrel for the first time on record
US diesel margins topped $100 a barrel for the first time on record, and that number is the one that matters for anyone moving product or pricing a c-store forecourt this week. The diesel crack spread, the gap between crude and wholesale diesel, cleared $100 as Brent traded around $91 and WTI near $85. When the crack runs that hot, your delivered cost climbs faster than the pump sign, and margin on the fuel island gets thin fast.
The WSJ reported diesel buyers competing for a shrinking supply pool, which is the part jobbers should watch. Tight supply plus a record crack means allocation risk at the rack. If your supplier starts limiting lifts, you feel it before the retail price catches up.
Hormuz risk
Crude climbed as US-Iran talks stalled and Iran said it would take a "fully offensive" stance. Traffic through the Strait of Hormuz, the chokepoint for a big share of seaborne crude, is the reason the market keeps bidding oil higher even with gasoline demand down. AAA put the national average at $4.06 a gallon, up 5 cents on the week and the highest August on record. Western Pennsylvania actually fell 3 cents to $4.16, so the move is not uniform, but the direction nationally is up.
Houthi forces claimed a third drone strike in two weeks on Saudi Aramco's Jazan refinery on the Red Sea coast. Refinery hits matter more than crude headlines right now because the squeeze is in product, not barrels. Diesel is the tightest link, and every strike on refining capacity in the region feeds the same fear that pushed the crack to a record. Crude could ease if the strait stays open and the talks restart, but nothing this week points that way yet.
Year-round E15
The US House passed a bill to allow year-round E15 sales, the 15% ethanol blend now blocked in summer months. It faces an uncertain path in the Senate. EPA granted a waiver this year to keep E15 flowing through the summer, so the bill would lock in what a waiver now handles case by case.
For retailers who already carry E15, permanent year-round sales would remove the annual scramble around the summer restriction and the paperwork that comes with it. Rep. Julie Fedorchak, R-N.D., hosted the roundtable pushing it, and the room was mostly agriculture interests who gain from more corn-based ethanol demand. The consumer-savings pitch is real at the margin, but the corn lobby is the engine. If you are weighing a blender pump or an E15 dispenser, the regulatory risk of the summer ban looks set to keep fading whether or not the Senate acts, given EPA's willingness to waive.
What to watch
Whether any supplier starts formally allocating diesel is the near-term signal. A record crack with buyers already fighting for barrels is the setup for it. Watch the Jazan refinery and any further Red Sea strikes, since product supply is the tight spot, not crude itself. On E15, the question is whether the Senate moves at all before the next summer season or leaves the annual EPA waiver as the only path. And keep an eye on whether the national average holds above $4 or the Pennsylvania-style pullbacks spread.
