Crude Oil Analysis: Why This Diesel Crack Spike Matters for Prices at the Pump
Key Points:
- Diesel crack spreads are exploding to $50.34/bbl over gasoline—a structural margin expansion that guarantees new pump highs regardless of crude flat price.
- The EPA's gasoline supply waiver (Sept 1-15) will crush petrol margins while diesel faces a tightening refinery window, forcing refiners to chase an ever-widening crack.
- Broad geopolitical risk spanning Red Sea, Hormuz, Bab al Mandeb, and Black Sea threatens to destabilize energy and food supplies, pricing in a FX debasement trade (lower DXY, higher rates, higher gold).
We are at an interesting junction now, transitioning into the third order consequences of The Iran war. The first order consequences we all know: 20mb/d Hormuz lost, down to about 4mb/d, which have since crawled back to 7mb/d and 15mb/d depending on who was counting last week- more below. Refinery runs got walloped from 86.3mb/d in Dec 2025 to 80.9mb/d, showing up as a false demand decline of 2.4mb/d- read my last post. Middle East plus Russian diesel and gas oil exports moved down to 1.6 mb/d (Vortexa). US distillate also drained to 103.4 mb, 14% below the five-year average, the lowest for the time of year in thirty years. All cushioned by an IEA 400mb strategic band aid. This priced into $119 Brent highs and priced out in the first month and has us holding at 43% higher prices than in Feb.
