Oil Above 100 is a Real Supply Shock but NOT a Permanent Price Regime
Iran War and Strait of Hormuz Oil Price Outlook
Brent crossed US$105 a barrel in September 2026 as attacks on shipping around the Strait of Hormuz intensified. This report asks whether triple-digit oil reflected a war premium, a physical shortage or the start of a lasting price regime.

ICE Brent futures, 9 September 2026 snapshot, as cited in the report.Summary
The move above US$100 reflected a physical supply loss. By early September the EIA estimated that 6.7 million barrels a day of Gulf crude production had been shut in during August, and the IEA estimated that observed global inventories had fallen by 410 million barrels between the start of the war and the end of July. Dated Brent, the physical benchmark, had traded above US$100 before front-month futures followed.
I argued that a price above US$100 already discounted a serious and persistent disruption. The futures curve fell sharply into 2027, demand was weakening under high prices, and pipelines, ship-to-ship transfers and strategic stocks were absorbing part of the shock.
My base case was Brent at US$95–115 over the following month, US$85–100 at the end of 2026 and an annual average of US$70–90 in 2027. I held that view with medium confidence, because dark shipping obscured true flows and a single diplomatic or military event could move the front of the curve by double digits.

Figures from the report.
Key findings
Physical tightness came first. Dated Brent traded above US$100 from 3 September, before the surge in front-month futures, which supported the view that prompt scarcity was real and not only a reaction to military headlines.
Spare capacity sat on the wrong side of the chokepoint. The IEA estimated only 1.09 mb/d of effective OPEC+ spare capacity in July. Bypass pipelines offered a potential 3.5–5.5 mb/d, and the IEA warned that the upper end had not been robustly tested.
Refined products were tighter than crude. Diesel and jet fuel exports from Russia, the Middle East and Asia were sharply lower, and the report said product tightness could persist even if Brent fell on a ceasefire.
Backwardation was the market’s working assumption. An ICE snapshot on 9 September showed Brent at US$100.45 for November 2026 and US$77.87 for December 2027. The curve priced scarcity now and relief later, which made deferred prices the test of whether the shock was permanent.

Methodology and benchmark notes
Every published call and dated base-case benchmark view is included, including misses. Duplicate calls appear once. Entries are publication references, not executed trades. Moves are price changes, not forecast verdicts. Brent uses front-month futures. Related spot or indicative points are chart context; outcomes use the stated benchmark. Daily and weekly sources keep their actual observation dates.
Base case for the 2027 average Brent price.
What would change the view
Would weaken the view
- Insured flows recover for two weeks, physical premiums compress and Brent falls below roughly US$90 as the curve flattens.
- Gulf output stays at least 4 million barrels per day below pre-war levels into early 2027 while deferred Brent moves above US$100.
- Diesel and jet margins compress rapidly, signalling that refinery and product supply is normalising.
Would move it either way
- A sustained recovery in Chinese imports would amplify Gulf supply losses; a renewed pullback would absorb part of the shock.

From the report
| Scenario | Operating assumption | One month | End of 2026 | 2027 average |
|---|---|---|---|---|
| De-escalation and reopening | Verified ceasefire, insured passage and Gulf production restarts | US$80–95 | US$70–85 | US$60–75 |
| Contained persistent disruption (base case) | Hormuz stays impaired, bypasses partly offset losses and demand weakens | US$95–115 | US$85–100 | US$70–90 |
| Prolonged severe disruption | Hormuz and Red Sea routes deteriorate and Gulf output remains several mb/d below normal | US$120–150 | US$110–140 | US$100–130 |
Bars share one scale within each column, starting at zero.
One-month and end-2026 figures are endpoint ranges; the 2027 figure is an annual average.
Data and approach
The scenario ranges are analyst assumptions anchored to observed prices, the ICE futures curve, the EIA’s official path and published bank forecasts. They are not probability-weighted. The report treats production shut-ins, Gulf exports and Hormuz transits as separate measures that cannot be added together and notes where the IEA and EIA use different definitions.
