Oil rose again on 4 September 2026. Market reports put Brent crude at about $96 a barrel and West Texas Intermediate at about $92.
For the week, Brent was up more than 7%. WTI was up about 9.8%. Both were on track for their largest weekly gain since the week ended 20 July.
The move is a risk premium, not a quiet inventory story. Traders are pricing US–Iran fighting that reached civilians this week and again put the Strait of Hormuz in the frame. See related coverage of the Kuhestak wedding-strike investigation.
What the market is pricing
US strikes in southern Iran this week killed and wounded dozens, according to Iranian officials. Iran answered with missiles and drones aimed at US and allied sites in the Gulf, including in Kuwait, Bahrain, and Jordan.
The strait remains the hinge. A large share of seaborne crude still has to pass it. Iran has tightened restrictions on shipping there. The barrels do not have to stop moving for the price to rise. Higher war-risk insurance, slower transits, and cargoes that take a longer route are enough.
On 1 September, Brent had already pushed through $90. By 4 September the weekly chart was the story: the biggest jump since mid-July. Earlier Utila coverage of that first move through $90 is the baseline this week’s rally built on.
Inventories and OPEC+
The US Energy Information Administration said commercial crude stocks fell to about 424.5 million barrels in the week ended 28 August, from 428.9 million a week earlier. The Strategic Petroleum Reserve held about 286.6 million barrels.
OPEC+ is expected to leave October output policy unchanged at a meeting on Sunday. The group has been unwinding one layer of production cuts. Shipping risk in Hormuz now matters more to the price than that meeting’s fine print.
What banks are warning
JPMorgan has estimated that each extra month of disruption could add about $7 to $8 a barrel to Brent. A three-month disruption, in that estimate, would take average monthly Brent toward about $114.
Goldman Sachs has said Brent could reach $120 if Hormuz shipping stays disrupted. Its base case still assumes tensions ease. In that path, the bank has pointed to Brent averaging about $80 in the fourth quarter and about $75 next year.
Those figures are bank scenarios, not a forecast Utila is making.
How the price reaches households
Crude feeds petrol, diesel, and jet fuel. A week of $90-plus, then $96, shows up in commuting, freight, and airfares. Central banks watch that chain because energy is a fast path into inflation. The same fighting that produced a civilian investigation in Kuhestak is the fighting that is now in the weekly oil chart.

Key Takeaways
- On 4 September 2026, Brent was about $96 and WTI about $92.
- Both were headed for their biggest weekly gain since mid-July.
- The driver is US–Iran fighting and risk to the Strait of Hormuz, not a routine inventory print.
- US commercial crude stocks fell to about 424.5 million barrels in the latest EIA week.
- OPEC+ meets Sunday on October output. Bank scenarios for a longer Hormuz shock run as high as $114–$120 Brent.
