XLE still looks like Exxon U.S. distillate inventories sat 14% below their five-year average in the week ended August 28; diesel set a record as the S&P 500 energy fund XLE rose 2.2% through Friday, September 4. By ETF.net Research. Published Sep 5, 2026. U.S. refiners processed **17.5 million barrels** a day in the week ended August 28, running at **98%** of capacity, and still could not refill diesel tanks. Distillate production decreased to 5.1 million barrels a day. The shortage already had a clock: on August 29, before this week’s trading began, Russia extended a ban on diesel exports through September 30. ## U.S.-Iran strikes repriced crude October NYMEX West Texas Intermediate closed Friday at **$91.48** a barrel, **9.7%** above last Friday’s $83.40. Most of that rebound printed Monday and Tuesday. Monday’s 2.8% gain, to $85.76, was the warmup. Tuesday, September 1, the contract rose **5.2%**, to $90.22, as U.S. and Iranian forces traded the most substantial exchange of fire since July. The war, which began February 28, is in its seventh month. A 60-day memorandum to end it expired in mid-August, and the Strait of Hormuz, which in 2024 carried about one-fifth of global petroleum liquids consumption, is the waterway those strikes put back in the market. Chart: Crude held the rally. **XLE** peaked Wednesday and slipped. Front-month ICE Brent futures settled Friday at **$92.68**, up $0.76, or 0.8%, and **7.6%** on the week. U.S. tanks, when they reported on Wednesday, described a different shortage. The Energy Information Administration’s Weekly Petroleum Status Report, covering the week ended Friday, August 28, showed commercial crude inventories excluding the Strategic Petroleum Reserve down **4.5 million barrels**, to 424.5 million, still 1% above the five-year average. Crude is not the tight stock. Distillate inventories rose 0.8 million barrels and still sat **14%** below their five-year average. Gasoline inventories fell 1.2 million barrels, 6% below average. Crude imports rose 612,000 barrels a day, to 6.8 million. The pump made the same point. The U.S. diesel average reached a record **$5.85** a gallon on Friday, as Middle East hostilities layered onto a diesel market already missing Russian export barrels. ## Exxon weighted XLE. Refiners moved it The fund of S&P 500 energy companies XLE is a $42.5 billion portfolio of 21 holdings as of Friday, September 4. Exxon Mobil is **19.9%** of it; Chevron is **15.2%**. Together they are more than a third of what a holder owns. This week Exxon rose 1.8%, to $159.47, and Chevron 3.3%, to $208.60. That is not a 9.7% oil week. The stocks that did the work sit further down the list. Marathon Petroleum, 5.6% of the fund, rose 5.4%. Valero Energy, 5.2%, rose 5.2%. Phillips 66, 5.5%, rose 4.5%. Chevron contributed 0.51 percentage points to the fund’s **2.2%** week, the most of any holding. Kinder Morgan, a pipeline name, fell 0.5% and was a small drag. The equal-weight oil and gas producers fund XOP is built as a slice of exploration, production, and refining. Its largest positions this week were refiners: PBF Energy, HF Sinclair, Marathon, Delek, Valero. It still gained only **2.6%**. Oilfield-services fund XES gained **2.2%**. Across the producer-equity wrappers, the week looked the same: a fraction of the barrel, with the refining names doing more than the wellhead names. That is the construction the ticker conceals. XLE will always look more like Exxon than like a crack spread. A war premium in crude and a shortage in diesel are not the same trade, and a cap-weighted energy fund is a blend of both. Table: What you hold, Week through Friday Only the futures wrapper moved with the barrel. The next test is seasonal, and it lands quickly. The EIA’s Short-Term Energy Outlook is due Wednesday, September 9, the same day as the next Weekly Petroleum Status Report. The August outlook has refiners reducing utilization and crude inputs for seasonal maintenance in September and October, dropping below **16 million barrels** a day on average in October. OPEC’s Monthly Oil Market Report follows on Thursday, September 10. If utilization comes off **98%** while distillate is already **14%** below its five-year average, the shortage that showed up at the diesel pump can outlast this week’s crude rally.
