The oil market's binding constraint stopped being crude. It's refining capacity and that doesn't get fixed by a ceasefire.
TL;DR: The Hormuz shock migrated downstream, the scarcity is in refining capacity, not crude, and a meaningful share of what's offline is physically destroyed, so it can't mean-revert with margins like a normal cycle. That makes the setup asymmetric: a strait reopening is bearish crude but much closer to neutral for cracks. Refiner equities have run 80–100% YTD but still trade at 6–8x, priced as if the E doesn't repeat, and I think mid-cycle earnings have partially reset higher. Biggest risks: distillate demand rolling over (the number to watch), faster-than-expected repairs, and export-curb politics. This is a 2026–27 thesis, not a decade one.
Most of the Hormuz commentary is still arguing about crude: how many barrels are stranded, when the strait reopens, what OPEC spare capacity can offset. I think that framing is a lap behind the market. The scarcity migrated downstream, and the evidence is in the spreads rather than in flat price.

The setup
Crude and products have decoupled. Crude is well off its wartime highs, Brent is around $87 against an April peak near $121, while product cracks sit at or near record highs. That is not what a pure crude-supply shock looks like; in one of those, everything rallies together. (JPMorgan's commodities team has been making the same observation: the shock is increasingly a refining story, not a crude story.)
The numbers, as of mid-August:
- The US 3-2-1 crack spread has been trading roughly $59–70/bbl since mid-July, including a record $70 print on July 16. Refining margins have roughly tripled since the start of 2026. Gulf Coast and Atlantic Basin margins hit all-time highs in July.
- Global refinery runs down ~4.7 mb/d YoY in Q2 2026 per the IEA, and June was still running ~6 mb/d below year-ago, a mix of war damage, export restrictions, and feedstock stranded behind Hormuz.
- Russia processed ~3.5–3.6 mb/d in July (EA Analytics data via Bloomberg), the lowest since 2002, against a 5.3–5.6 mb/d norm for the period. Provider estimates diverge, Kpler has July closer to 4.2, but everyone agrees on multi-decade lows. FT-cited estimates of capacity disabled by drone strikes run 20–40%, and roughly 45 Mt/yr was still offline as of late July per Russian state media. On top of that, Moscow banned diesel exports outright on July 8, call it ~10% of waterborne diesel supply pulled from the market.
- Middle East runs averaged 6.5 mb/d in Q2, −27% YoY (Kpler), with damage at Saudi Jizan and SATORP, Bahrain's Sitra, and Kuwait's MAA and MAB.
- US distillate inventories are 12% below the five-year average (week ending Aug 7) seasonally the lowest since 1996. And note: back in February 2025, before anyone was shooting at anything, the EIA was already forecasting gasoline, distillate and jet stocks would hit their lowest levels since 2000 this year, purely on closures and demand.
- Distillate exports hit 1.884 mb/d (week ended July 31), the highest weekly figure in EIA records going back to 2010, topping the prior record set May 1.
Why this isn't a normal margin cycle
Refining margins are cyclical and they mean-revert. The standard mechanism is: high margins → utilization rises, idled capacity restarts, new builds get commissioned → margins compress.
That mechanism requires capacity to exist.
A meaningful share of what's gone is physically destroyed. You cannot restart a cracked distillation column or a wrecked hydrotreater because the margin environment improved. Repairs run quarters at best; rebuilds run years and billions in capex capex that boards have been extremely reluctant to commit in a sector everyone spent the last decade calling terminally declining.
The pre-existing structure makes it worse:
- The 2026 pipeline of new capacity is thin and in the wrong place: roughly 1–1.5 mb/d of gross additions expected this year, nearly all East of Suez, partially offset by further shutdowns. Atlantic Basin additions are effectively zero, and the IEA has global runs falling 2.4 mb/d this year before rebounding 3.1 mb/d in 2027.
- Nearly 800 kbd permanently shut in 2025 alone: LyondellBasell Houston (268 kbd), Grangemouth in the UK (150), Shell Wesseling in Germany (150), Phillips 66 Los Angeles (139), plus 70 kbd at BP Gelsenkirchen. Gone regardless of what margins do.
- OPEC's own World Oil Outlook has the required-vs-potential capacity deficit widening from ~0.5 mb/d in 2027 to ~1.6 mb/d by 2030.
The industry was already tightening into a capacity wall before anyone hit anything with a drone.
The part I think is most underpriced
A Hormuz resolution is bearish crude but much closer to neutral for cracks. Reopening the strait moves barrels. It does not rebuild Jizan, or Sitra, or the Russian kit. If the strait reopens, crude likely sells off, and refiners get cheaper feedstock into the same tight product market, which is not obviously bad for margins.
The honest caveat, so nobody has to make it for me: not all of the Q2 outage complex is destruction. A chunk of it is feedstock, Chinese and Japanese crude imports each fell ~40% during the worst of it, and those Asian runs come back when flows normalize. So a reopening does restore some product supply, not just crude supply. The asymmetry holds for the wrecked kit, not the starved kit. My claim is that the wrecked-kit share is large enough that cracks stay historically elevated through a reopening, just off the extremes.
That asymmetry is the whole thesis. You don't have to be right about the geopolitics to be right about the spread.
Equities have partly figured this out, MPC and VLO have roughly doubled in 2026 and HF Sinclair is up 80%+, against an S&P up ~11%, but the multiples still price these as cyclical peak earnings. PBF trades around 6x and HF Sinclair around 8x on 2026 earnings power (trailing P/Es are noisy right now, since the trailing window still includes loss quarters), versus 12–14x for the larger, better-diversified names. Those multiples are the market saying we don't believe the E repeats. The whole question is whether mid-cycle EPS has structurally reset higher. I think it has, at least partially, and 6x doesn't reflect that.
What I might be wrong about
Taking the bear case seriously, because it isn't weak.
- Demand destruction. A $60 crack is a tax on every gallon consumed. Historically, product prices this high destroy demand and compress cracks without a single refinery coming back. Counterpoint, for now: four-week US distillate demand is running 3.7 mb/d, up ~2% YoY. Demand hasn't cracked yet. This is the single most important number to watch, and if it rolls over the thesis is in trouble.
- "Structural" is not "permanent." Kpler expects global outages to trend lower from August onward, though the same note has Middle East repairs keeping effective capacity well below normal and margins elevated through at least year-end. Russia's diesel export ban is reportedly slated to lift as soon as September, which would put several hundred kb/d of exports back on the water, and the EIA's August STEO has most disrupted production recovering by early 2027. The tightness decays month by month. This is a 2026–2027 thesis, not a decade one, and anyone treating it as permanent will overstay.
- Policy risk. Margins this fat on consumer fuels attract political attention, windfall taxes, export restrictions, forced allocation. The precedent already exists this year: Russia banned diesel exports outright and China has kept its product export controls tight. Record US distillate exports alongside domestic stocks 12% below average is exactly the optic that generates export-curb legislation.
- The trade is crowded and the charts are vertical. Everything named here is at or near 52-week highs after doubling. Being right on fundamentals and wrong on entry is a completely normal way to lose money.
What would falsify it
- Distillate demand rolling over meaningfully YoY
- Cracks breaking back under ~$35 and holding
- Distillate inventories rebuilding toward the five-year average
- Credible restart timelines on damaged Gulf capacity landing sooner than expected
Genuinely interested in pushback, especially from anyone closer to the physical side. The piece I'm least confident about is repair timelines on the damaged Middle East units, the most recent public read (Kpler, Aug 8) has maintenance elevated through year-end even if the maritime picture eases, but most of what's public is vague. If those units come back faster than the "months" everyone keeps repeating, this compresses quicker than the equity market is positioned for.
