$108 Diesel Crack, Then a Waiver: The Refining Trade Meets Its October 22 Reckoning

The executive order, released by the White House on Friday, Oct. 17, invokes Section 115(a) of the Graham Act and waives duties, sanctions and restrictions across 13 of the law's operative sections — leaving only the underlying Russia state-of-emergency architecture intact. Section 4(c) alone waives the application of sections 102(a), 102(e), 103, 104, 105, 106, 107, 108, 109, 110, 111 and 117, which is the bulk of the law's targeting machinery.

Layered on top, the US Treasury on Oct. 9 issued a temporary general license allowing the sale and import of Russian diesel into the global market, including the United States, through April 7, 2027. That license is what operationalizes the diesel trade Trump previewed at the same time — 300,000 metric tons immediately, 500,000 tons in November, and a further 1 million tons immediately thereafter, totaling roughly 4.8 million tons across October to December.

The US Gulf Coast ultra-low sulfur diesel crack spread averaged $107.90 a barrel in September 2026, against $28.62 in January, according to Reuters/Crux analysis. The 3-2-1 crack spread — the street benchmark that blends two barrels of gasoline and one barrel of distillate against three barrels of crude — was $64.83/bbl on Oct. 6, the highest monthly average since 2006 and a reading higher than 99% of the 40-year EIA record.

That wedge was not a free-market phenomenon. It was the product of three converging shocks: Ukrainian drone strikes took an estimated 60% of Russian refining capacity offline over the summer; Russia itself imposed an export ban on diesel through the end of October; and the Graham Act was supposed to lock the country out of US-priced markets through 100% secondary tariffs on Chinese and Indian buyers.

The headline reads 'more Russian fuel exports,' but Russian diesel flows are physically capped by refinery damage. According to Spherical Insights/IEA analysis, the staged tranches Trump announced — 300,000 tons immediately, 500,000 tons in November, 1 million tons in December — come to roughly 4.8 million tons or 36 million barrels through year-end. That is less than eight days of global seaborne diesel trade.

Goldman Sachs estimates the policy shift will trim wholesale diesel benchmarks by only $1–2 a barrel on the US Gulf Coast and in Northwest Europe. The point is not that Russian diesel washes out the crack spread; the point is that the assumption which priced the crack spread no longer holds.

US independent refiners have been the single best-performing slice of the energy market in 2026. Valero closed at $444.71 on Oct. 17 — up 153% year-to-date. Marathon Petroleum at $478.07 is up roughly 162% YTD; Phillips 66 at $293.17 is up about 106%. PBF Energy closed at $89.51 on Oct. 14, up 204.7% over twelve months. The rerating was driven directly by Q2 2026 refining margins that ran multiples of their year-ago levels.

Those figures will still print in Q3 — Valero reports Oct. 22 with a consensus EPS estimate of $19.48, up from $12.54 in Q2 — but the multiple question is forward. The market is now repricing what 2027 margins look like under a policy regime that allows Russian diesel to flow at any volume.

The other corner of the supply chain is the tanker market — and there the waiver reads more ambiguously. The US is reportedly weighing a separate easing of sanctions on Russian 'shadow fleet' tankers. Kpler, however, expects 'virtually no impact' on tanker availability, because the ~160 supertankers currently under US sanctions face EU sanctions and lack the insurance and certification that mainstream charterers require.

Of the sanctioned fleet, only about 24 ships are young enough and compliant enough to rejoin global trade once age, EU sanctions, and ownership constraints are layered in. The visible response has been modest: US Gulf Coast-to-Europe Aframax freight futures fell 30 points on the news, while VLCC TD3C rates on the Arabian Gulf–China route averaged WS1,288 in Week 41 2026, up 12% week-on-week. The BDTI — Baltic Dirty Tanker Index — climbed 32% to 7,625 points for the week.

The other side of the same waiver is the world's largest buyers of Russian crude. India averaged 1.82 million bpd of Russian seaborne crude in September 2026, against China's 1.49 million bpd — both ahead of Turkey, Italy and the Netherlands, per Kpler/ship-tracking data cited by PTI. With secondary sanctions paused, India is expected to hold October imports near 1.8–1.9 million bpd and refiners there can keep running Urals at a $23/bbl discount to dated Brent (the September average).

Reliance Industries — operator of the world's largest single-site refinery at Jamnagar — has run a 'Russian-off, Russian-on' rhythm through 2026: it stopped Urals imports in November 2025, resumed at ~150,000 bpd in February 2026 from non-sanctioned sellers, and is now free to import at fuller scale. CNOOC and PetroChina on the Chinese side hold the same option, with Chinese refiners having absorbed roughly 50% of Russia's crude exports through the most recent monthly tracker.
