Brent crude climbs above $90 a barrel after US-Iran strikes in Hormuz

Monday, August 31, 2026 · 3 sources

Brent crude futures rose above $90 a barrel on Monday after the first US-Iran military exchange in about a month. West Texas Intermediate also gained as traders weighed fresh risk to Gulf shipping.

NEW YORK - Brent crude, the global oil benchmark, climbed back above $90 a barrel on Monday after US forces struck Iranian positions in the Strait of Hormuz and Iran answered with missile fire toward American sites in the region.

Early trade saw Brent up roughly 2% to about $90.50 a barrel, with some prints near $90.60, according to Associated Press, MarketWatch and energy-desk reports. US West Texas Intermediate rose a similar pace to the mid-$85 range.

The rally followed Sunday's US strike on two Iranian rocket launchers on Larak Island. Central Command said the launchers were being readied to put sea mines into the strait. Iran's Revolutionary Guard said it retaliated against US bases in Jordan. Jordan reported intercepting incoming missiles.

Hormuz is the outlet for Persian Gulf crude. Tanker traffic has already been thinner during the six-month conflict. Traders treat any new mining threat or base attack as a reason to rebuild a geopolitical premium in the price.

The move comes as Federal Reserve Chair Kevin Warsh's Jackson Hole remarks also shaped rate expectations. Higher oil can feed inflation readings that the Fed watches. Stock index futures slipped in early trade as investors weighed both energy risk and the chance of firmer US rates.

For households, a one-day crude jump does not lock in pump prices. Retail gasoline lags crude and varies by state taxes and refining. Still, seniors on fixed incomes feel it quickly when a fill-up or propane delivery costs more. AAA and state energy offices remain the practical check for local averages.

Analysts said prices will stay jumpy until shipping through Hormuz looks steadier or diplomatic tracks reduce the odds of another strike cycle.

The 50+ takeaway: Brent moved back above $90 on Hormuz risk. Watch the next few sessions and your local pump average before changing long-trip or heating plans.

Go Deeper

How high did oil go?

Brent traded above $90 a barrel Monday morning, up about 2% to 3% in early reports. WTI rose into the mid-$85 range.

Why did prices jump?

Markets reacted to the first US-Iran military exchange in about a month inside the Strait of Hormuz, raising fears of fresh mining or shipping delays.

Will my gas price rise tomorrow?

Not automatically. Retail gasoline trails crude by days or weeks and depends on local supply. A sustained crude move is more likely to show up at the pump than a single session.

How does this relate to the Fed?

Higher energy prices can keep inflation sticky. That is one reason stock futures also watched Warsh's Jackson Hole comments on fighting inflation.

What should retirees watch this week?

Local AAA pump averages, heating-fuel quotes if you use oil or propane, and whether Hormuz traffic reports stabilize after the weekend strikes.
