Crude oil futures were mixed this week as markets balanced severe Middle East infrastructure outages against reports of pipeline restoration and rerouted exports.
West Texas Intermediate settled at $99.40 per barrel, down from $99.99/bbl the previous week, while Brent closed at $103.05/bbl, up from $104.50/bbl a week earlier.
While WTI futures gained marginally over the week, Brent shed 1.23%.
Geopolitical and operational disruptions remained the primary market drivers.
Prices settled higher on Monday due to pipeline strikes and vessel attacks. Futures climbed again on Tuesday amid ongoing outages, retreating on Wednesday as Saudi Arabia offered additional Asian cargoes via Oman. Thursday and Friday saw further pullback amid reports of pipeline restoration progress and export rerouting.
"Middle East oil flows remain surprisingly strong despite the disruption to Saudi Arabia's East-West pipeline," J.P. Morgan analysts said. They said that over the past 10 days, total oil flows averaged 17.1 million barrels per day, about 6.1 mmb/d below the 2025 average.
Last week, Saudi Arabia shut its East-West oil pipeline as a precaution following attacks in the Riyadh and Medina regions. However, latest reports indicate Riyadh is seeking to restore about half of its capacity within days and is boosting ship-to-ship transfer operations off Oman's Sohar port to supply Asian refiners.
Meanwhile, the US blockades reduced Iranian crude exports to roughly 210,000 barrels per day in August.
US Secretary Wright noted during a Fox News interview that 18 million barrels of crude and refined products moved through the Strait of Hormuz with US assistance. The US Department of Energy confirmed the remarks in an emailed response to.
Commerzbank analysts highlighted that the Middle East shock is increasingly transmitting to Asian energy costs via higher crude prices and sharply higher freight rates.
On the supply side, the US Energy Information Administration said in its weekly report commercial crude oil inventories decreased by 600,000 barrels to 423.4 million barrels in the week ended Sept. 11. The draw contrasted with a 7.1 million-barrel build reported by the American Petroleum Institute for the same period.
Meanwhile, the UK Maritime Trade Operations issued alerts about two separate incidents in which tankers in the Strait of Hormuz were struck by unknown projectiles, resulting in fires that were successfully extinguished without reported casualties.
At the same time, Ukrainian strikes on Russia's Syzran refinery in the Volga region helped drive diesel prices to record highs, coming on the heels of a proposed energy truce floated by Presidents Trump and Volodymyr Zelenskyy.
Average US pump prices have climbed to $4.47 per gallon for gasoline and $6.45/gal for diesel, driven by massive spikes in the Great Lakes states that underline zero tolerance for domestic refining downtime, energy expert Tom Kloza posted on X on Friday.
US diesel prices reached a record average of $6.44 per gallon, adding to fuel-cost pressure as global supplies remain constrained, the American Automobile Association said Friday. US diesel prices averaged $5.47/gal a month earlier and $3.71/gal a year earlier, AAA data showed.
The US oil rig count rose by two from 450 the previous week to 452 in the week ending Sept. 18, according to data from Baker Hughes (BKR) released Friday. The US had 418 oil, 118 gas, and six miscellaneous rigs in operation a year earlier.
The consolidated North American oil and gas rig count, a key early indicator of future production levels, decreased by six to 792 from 798 the previous week.
Money managers stayed net long WTI crude futures and options for the week ended Sept. 15, per the CFTC's latest Commitments of Traders report, released Friday. However, the margin narrowed slightly as fresh short selling outpaced new long buying.
The data showed that money managers reported 229,893 long positions, up 3,140 from Sept. 8, while short positions rose 5,711 to 93,125. That puts net long positions at 136,768 contracts, down about 2,600 from the prior week's 139,339, indicating a modest drop in bullish speculation.
