Oil turned meaningfully more expensive in August, and the federal government’s own energy statisticians have the number. The U.S. Energy Information Administration reports that the Brent crude oil spot price, the global benchmark that shapes most of what drivers pay at the pump in the United States, averaged $91 a barrel for the month, up $7 from July. A monthly move of that size in a global benchmark most households never track directly works through the supply chain in weeks, which means the households filling up in September are among the first to feel it.
Middle East Supply Shut-Ins Are Driving the Number
The increase did not come from a surge in demand. The agency’s September Short-Term Energy Outlook ties the jump to constrained oil exports out of the Middle East, where production shut-ins climbed to an estimated 6.7 million barrels a day in August, up from 5.0 million barrels a day in July. EIA links part of the tightening to a renewed U.S. blockade on Iran’s oil exports following attacks on tankers in the Strait of Hormuz, which has kept crude that would normally reach global markets sitting offline instead.
The effect shows up most clearly in inventories. EIA estimates that global oil stocks have fallen by roughly 400 million barrels so far in 2026, and the agency expects the drawdown to continue through the end of the year. That is the main reason it does not expect August’s price level to have been a one-month spike.
The tightening is not limited to crude oil. EIA’s outlook also flags strain in the global distillate market, the fuel category that includes diesel and home heating oil, forecasting that U.S. distillate inventories will drop below 100 million barrels in September and stay below the five-year (2021–2025) low through much of 2027. That matters beyond the truck stop: diesel is what moves freight, so a sustained increase in diesel costs works its way into trucking rates and, from there, into the shelf price of groceries hauled on those same routes.

What $91 Crude Means at the Retail Pump
Crude oil is the largest single component of the retail gasoline price, so a sustained move in Brent shows up directly in what a household pays to fill a tank. EIA’s outlook now forecasts the annual average retail gasoline price at $3.84 a gallon for 2026, up from $3.10 in 2025, before easing to $3.35 in 2027 as the agency expects global oil supply to loosen.
For a two-car household making a couple of fill-ups a week, the gap between $3.10 and $3.84 a gallon compounds over a full year of driving. It is not a one-time expense; it is a recurring line in the monthly budget that moves with the price of crude on the other side of the world, not with anything the household itself controls.
The gasoline number is itself a blend of three moving pieces: the crude price, the refining margin, and the retail margin added at the pump. EIA’s forecast assumes the crude piece does most of the work this year, since it is the component that jumped in August, while refining and retail margins have moved far less. That is a useful distinction for a household trying to judge whether a price at a local station reflects a national trend or a one-off local factor.
The Forecast Splits: A Pricier 2026, A Cheaper 2027
EIA does not expect August’s price level to hold indefinitely. The agency’s own report forecasts Brent will average around $90 a barrel through the second half of 2026, then gradually fall to an average of $74 a barrel in 2027 as shut-in oil production restarts and global supply catches up with demand. The same report expects U.S. crude oil production to keep climbing through the forecast window, from 13.7 million barrels a day in 2025 to 13.8 million in 2026 and 14.3 million in 2027, which is the supply growth EIA is counting on to eventually bring prices down.
That relief is not expected to arrive all at once. EIA projects the price will keep easing gradually through 2027, reaching an average of roughly $77 a barrel by the second quarter of that year rather than dropping in a single move. For households budgeting ahead, that means any pump-price relief from the 2026 highs is likely to show up in increments over the following year, not as a sudden drop the month the calendar turns.
Why the Number Jumped Now, Not Gradually
The scale of August’s move is unusual for a single month. A $7 jump in a global benchmark reflects how quickly a regional supply disruption can move a price that is otherwise driven by slower trends like production growth and seasonal demand. EIA’s own historical spot price series shows how rarely Brent moves this sharply from one month to the next outside a genuine supply shock.
The agency’s next Short-Term Energy Outlook, due in October, will show whether the Middle East shut-ins easing on schedule translate into the gradual price relief EIA has penciled in for 2027, or whether the disruptions that pushed August’s average to $91 a barrel prove more durable than this month’s forecast assumes.
