Record Pump Diesel Raises the Stakes for a U.S. Export Ban
September 17 brings a second energy-down, gold-up session, but today diesel futures are giving back more than crude. At the afternoon marks, October WTI fell $1.09 to $101.34/bbl and November Brent lost $1.81 to $104.02, while December gold edged $6 higher to $4,393.50/oz. December dollar-index futures barely moved at 99.955, down 0.02%. October gasoil dropped $44.75 to $1,493.25/mt and heating oil fell 17.26 cents to $5.0739/gal. The correction reached the structure: October/December gasoil backwardation narrowed $20.25 to $153.75/mt and October/January eased $25.75 to $216.25. The matching October heat crack fell from $117.92 to $111.76/bbl. Those are meaningful reductions, but October gasoil remains 72.4% higher over three months. The weekly chart still looks strong, and a crack above $111/bbl leaves considerable distance between a correction and a return to normal diesel economics.
The pump keeps moving the other way. The U.S. national diesel average reached a record $6.3956/gal, up 8.53 cents overnight and 41.83 cents in a week. Talk of an October 1 trucker shutdown is circulating on social media, although its organization and participation remain unconfirmed. Senate Majority Leader John Thune’s willingness to explore a diesel export ban is a more concrete political signal. I still expect pressure for restrictions to intensify if diesel stays near $6.40 heading toward November’s elections, but no ban has been announced. Congress has meanwhile cleared the Lindsey O. Graham Sanctioning Russia and Iran Act, with the House voting 262–159 after the Senate’s 86–11 approval. The legislation heads to the president and includes tariffs of up to 100% on qualifying major Russian-energy buyers and sanctions-evasion facilitators, with substantial implementation and waiver discretion. That gives the administration considerable latitude, although it is not unrestricted authority against any country. The next commercial question is which powers are exercised, against whom, and with what exemptions.
Soybean oil remains inside its narrowing consolidation, while the carry to early 2027 widened again. October settled at 68.68 cents/lb, down 0.51, against January at 69.42, taking October/January from −0.71 to −0.74 cents/lb, equivalent to a $16.31/mt nearby discount. October/March widened to −0.90, although October/December tightened slightly to −0.47. The weekly range of 67.80–70.60 cents still contains the pennant, with moving averages at 67.56 and 70.31 providing nearby reference points. Meal gained $7.80 to $368.70/short ton, pulling oil’s share of combined product value down to 48.22% while October board crush rose 5.22%. Cheaper oil nevertheless failed to protect biofuel margins. October BOGO widened $33.51 from −$12.64 to +$20.87/mt because gasoil fell harder, while December BOGO increased $13.04 to $184.98. December 2026 D4 RINs also slipped 1.185% to $2.042. Indicative October renewable-diesel margin fell 12.65 cents to $1.9161/gal and conventional biodiesel fell 13.16 cents to $2.3987/gal. The product and credit sides did more damage than lower feedstock could offset. Industry still looking at remarkable conventional Biodiesel margin under RFS with only RINs included.
Europe continues to show limited physical-window business alongside substantial paper turnover, but the German harvest adds a feedstock constraint worth watching. The German Federal Statistical Office puts rapeseed output at roughly 3.5 million tonnes, nearly 13% below 2025, with other harvest estimates ranging from 3.3 million to 3.7 million tonnes. Initial average oil content of 43.5% does not remove the smaller seed-volume problem. That gives RME producers another reason to watch rapeseed-oil replacement costs even as energy retreats; it does not, by itself, establish a wider RME margin. Today’s spot window recorded nine transactions, with RME at a $400/mt premium, FAME0 averaging $364 and UCOME $500, leaving RME/FAME at $36. Paper through Wednesday, excluding Thursday and Friday, already totals 464.4kt: RME 115kt, FAME0 104.5kt, UCOME 97.8kt and HVO2 147.1kt. That is 73.3% of the previous full week’s 633.4kt, while FAME0 has already exceeded its prior weekly total by 14.2%. A separate Thursday tally records 78kt across outright and spread categories. Industry conferences in Monterey on September 15–17 and Bali on September 17–18 may be contributing to thinner physical participation, but paper trading has clearly continued.
Bali Conference immediate message is B50 for 2027, with Indonesian officials indicating at least another year of preparation before B60. October dollar CPO fell $17.75 to $1,219.50/mt. A Malaysian producer sample showed September 1–15 production 21.28% above the comparable previous-month period, moderating from 26.62% for September 1–10 but still showing growth. Logistics on Rivers remain restrictive almost everywhere: Kaub on Rhine returned to 21cm, with standard barge intakes near 500 tonnes, while St. Louis recovered to 1.82ft but Memphis remained below zero at −1.20ft. Available UCO indications offer no fresh Thursday assessment: CIF ARA bulk at $1,365–1,375/mt still refers to the week ending September 10. My focus now is whether gasoil retains its $153.75/mt October/December premium and whether soybean oil breaks the 67.80–70.60-cent weekly range. Today brought softer diesel scarcity premiums and weaker biofuel conversion margins, while Germany’s roughly 13% smaller rapeseed crop adds a separate European supply concern. With retail diesel at a record and European paper already at 464.4kt through Wednesday, neither commercial exposure nor political pressure has gone away but traders prefer paper to hedge this risk.
