Key Facts
- The crude tracking fund closed at US$155.31, down 0.55%, a second consecutive fall as supply fears eased.
- West Texas Intermediate settled near US$101.91 and Brent at US$104.82, both lower as Saudi exports found a route around the damaged pipeline.
- Saudi Arabia is moving crude through ship-to-ship transfers near Sohar in Oman, avoiding the Strait of Hormuz while the East-West line is repaired.
- Petrobras raised its diesel reference price by one real a litre, about US$0.19, and a finance ministry order created a matching subsidy so distributors pay the same.
- Petrobras signed eight production-sharing contracts offshore Côte d’Ivoire, taking 90% operating stakes with the state company PETROCI holding the remainder.
- American crude inventories fell only 640,000 barrels, against expectations closer to 1.62 million, which added to the softer tone.
Today’s Focus
Oil fell for a second session as the market decided the Saudi supply problem is manageable. The crude tracking fund closed at US$155.31, down 0.55%.
West Texas Intermediate settled near US$101.91 and Brent at US$104.82. Both remain far above where they started the month.
The reason for the easing is logistical. Saudi Arabia is moving crude through ship-to-ship transfers near Sohar in Oman while its East-West pipeline is repaired.
That line was damaged by drones launched from Iranian-backed militias in Iraq. Two of its eleven pumping stations were hit.
American inventory data pointed the same way. Crude stocks fell only 640,000 barrels against expectations nearer 1.62 million.
Regional producers followed the price rather than leading it. Ecopetrol fell 0.46% and YPF 0.31% while Petrobras was almost unchanged.
What matters today. Repair estimates for the Saudi pipeline range from days to six weeks. The market is currently pricing the optimistic end of that range.

01 The session in one read
The oil market has spent a week pricing a supply interruption and is now pricing the workaround. Ship-to-ship transfers are expensive and slow but they move barrels.
Two consecutive falls suggest confidence rather than complacency. Prices are still well above their level before the attack.
The fund has retreated from the spike that followed the pipeline strike. It remains above where it traded at the start of September.
The shape of that move is what a resolved disruption looks like. A sharp rise, a plateau, then a slow give-back as alternatives appear.
02 The board
| Crude fund (USO) | US$155.31 | -0.55% | A fund share price, not a barrel price |
| West Texas Intermediate | US$101.91 | -0.51% | Holding above the hundred-dollar line |
| Brent crude | US$104.82 | -0.95% | Second consecutive decline |
| Petrobras (PBR) | US$20.94 | +0.14% | Barely moved despite the weaker crude |
| Ecopetrol (EC) | US$17.38 | -0.46% | Colombian producer followed the price |
| YPF (YPF) | US$54.48 | -0.31% | Argentine producer also eased |
The first line is the one readers most often misread. US$155.31 is the price of a fund share, not of a barrel of oil.
The producers moved far less than the commodity. That is typical when a price fall is expected to be temporary.
03 What moved it
Saudi Arabia’s East-West pipeline carries crude from the eastern oilfields to the Red Sea terminal at Yanbu. It was struck by drones, damaging pumping stations eight and nine of eleven.
The United States energy secretary said the line should be back within days. Regional officials and Reuters sources put full repairs at between three and six weeks.
In the meantime, exports are moving by ship-to-ship transfer near Sohar in Oman. That avoids the Strait of Hormuz entirely.
The inventory data reinforced the softer tone. A draw of 640,000 barrels against expectations of 1.62 million points to a better-supplied American market than forecast.
04 The Latin American read
Petrobras was almost unchanged at US$20.94 despite the weaker crude. The company had its own news to absorb.
It raised its diesel reference price to distributors by one real a litre, about US$0.19. A finance ministry order published on 16 September created a matching subsidy of the same size.
The net effect on distributors is zero, which is the point. Brazil’s government has neutralised a price rise without asking Petrobras to absorb it.
Ecopetrol fell 0.46% and YPF 0.31%, both tracking the crude price. Neither had company news of its own.
05 The names to watch
Petrobras signed eight production-sharing contracts offshore Côte d’Ivoire on Thursday. It takes 90% operating stakes with the state company PETROCI holding ten.
The blocks are CI-513, CI-600, CI-601, CI-602, CI-603, CI-605, CI-701 and CI-702. They extend the company’s West African exploration position significantly.
Ecopetrol remains the most exposed of the three to domestic politics. Colombian governance questions have shadowed the company through this month.
YPF is the Argentine shale story rather than a conventional producer. Its shares track Vaca Muerta volumes more closely than the Brent price.
06 The outlook
The refined product market is tighter than crude and getting less attention. European gasoil and American diesel futures both reached record levels this week.
That matters more for Brazil than the crude price does. Diesel is the fuel that moves Brazilian freight, and the government has just intervened to hold its price.
The last group decision from the producer alliance was on 2 August, adding 188,000 barrels a day for September. There is no meeting this week.
The pipeline timetable remains the main variable. If repairs run to six weeks rather than days, this week’s easing will be reversed.
The regional producers are positioned very differently for that outcome. Petrobras has a subsidised domestic market behind it while Ecopetrol and YPF are fully exposed to the export price.
Brazilian pump prices are therefore a political variable rather than a market one this month. The subsidy runs thirty days and is renewable, which places its expiry inside the election run-in.
07 What to watch
- The Saudi repair timetable: Estimates run from days to six weeks, and the market is pricing the short end.
- Refined products: European gasoil and American diesel futures hit record levels this week, which matters more than crude for Brazil.
- The diesel subsidy: It runs for thirty days and is renewable, so its expiry is a scheduled political event.
- Petrobras in West Africa: Eight new Ivorian blocks are a material addition to the exploration portfolio.
- American inventories: A draw of 640,000 barrels against 1.62 million expected suggests better supply than forecast.
Frequently Asked Questions
Why did oil prices fall on 17 September 2026?
Saudi Arabia found a route around its damaged East-West pipeline using ship-to-ship transfers near Oman. American crude inventories also fell far less than expected.
