US forces struck Iranian missile sites and mine-laying boats near the Strait of Hormuz on May 25-26, calling the action self-defense. By May 28, negotiators had agreed on a tentative 60-day truce framework covering Hormuz reopening, mine clearance, sanctions waivers, and nuclear talks. Trump had not yet signed off, and Iran suspended all talks through Pakistan mediators on June 1.
Oil surged more than 7% on June 1, hitting about $93 (WTI) and $95 (Brent), after Iran's state media announced Tehran would also move to block the Bab al-Mandeb Strait. Defense Secretary Pete Hegseth had warned at the Shangri-La Dialogue in Singapore on May 30 that the US was ready to resume major strikes. National gas prices stood at about $4.60 per gallon as the conflict entered its 93rd day.
Why it matters
Every week the blockade holds costs American drivers 52% more at the pump and edges the global economy closer to recession.
Brent at ~$95 and WTI at ~$93 as of June 1 after Iran suspended talks. Prices had fallen roughly 11% the prior week on deal optimism before surging 7%+ on the talks breakdown. Still about $25 above pre-war levels.
$4.60 (national avg)
U.S. average gasoline price per gallon
National average at about $4.60 per gallon as of the week of May 25. GasBuddy forecast a summer average of $4.80 per gallon through Labor Day.
Fell on deal hopes, reversed June 1
Global stock indices
Equities rallied in late May on US-Iran deal reports. Markets pulled back June 1 as Iran suspended talks and threatened a wider blockade.
~14M barrels/day offline; Bab al-Mandeb also threatened
Production offline
IEA estimate of ~14 million bpd removed from global supply remains unchanged. Iran's June 1 threat to also block the Bab al-Mandeb Strait puts another estimated 5-7 million bpd at risk. A dual chokepoint closure would threaten up to 25% of global oil supply.
Sri Lanka +18% tariffs; Malaysia remote work mandate
Global ripple effects
Sri Lanka raised electricity tariffs 18% citing Iran war fuel costs. Malaysia ordered government remote work from April 15. GasBuddy forecasts US summer gas prices averaging $4.80 per gallon.

Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
1 of 3
October 1973 - March 1974
Arab oil embargo (1973-1974)
After the United States provided emergency military aid to Israel during the Yom Kippur War, the Organization of Arab Petroleum Exporting Countries imposed an oil embargo on the U.S. and other Western nations. The price of oil quadrupled from $2.90 to $11.65 a barrel in under four months, producing gas lines, rationing, and a sharp recession.
Then
The U.S. economy entered a deep recession with double-digit inflation and unemployment rising above 8 percent. Congress imposed a national 55-mph speed limit to conserve fuel.
Now
The crisis led to the creation of the Strategic Petroleum Reserve in 1975 and the International Energy Agency to coordinate Western responses to supply disruptions. It permanently ended the era of cheap oil and reshaped American energy policy.
Why this matters now
The 1973 embargo demonstrated what happens when a major oil chokepoint is deliberately closed for geopolitical leverage — the exact mechanism now playing out in the Strait of Hormuz. The difference in scale: the embargo removed roughly 5 million barrels per day from the market. The Hormuz closure threatens roughly 17 million.
2 of 3
August 1990 - February 1991
Gulf War oil shock (1990)
Iraq's invasion of Kuwait on August 2, 1990, removed approximately 4.3 million barrels per day from global supply — the combined output of both countries. Oil prices roughly doubled from $34 to about $77 a barrel within weeks as markets feared Saddam Hussein would invade Saudi Arabia and seize a larger share of global production.
Then
Prices spiked sharply but fell back quickly once the U.S.-led coalition launched Operation Desert Storm in January 1991. Saudi Arabia ramped up production to partially offset the lost Iraqi and Kuwaiti output.
Now
The rapid military resolution limited the economic damage. The episode reinforced that oil shocks tied to Middle Eastern conflicts are measured not just by barrels lost but by how quickly supply can be restored.
Why this matters now
In 1990, Saudi Arabia served as the swing producer that cushioned the shock. In 2026, Saudi facilities themselves are under attack from Iranian drones and missiles — and the kingdom's primary export route through the Strait of Hormuz is the one that's blocked.
3 of 3
September 2019
Abqaiq-Khurais attacks (2019)
Drone and cruise missile strikes — attributed to Iran but claimed by Yemen's Houthis — hit Saudi Arabia's Abqaiq oil processing facility and Khurais oil field on September 14, 2019. The attack temporarily knocked out about 5.7 million barrels per day of Saudi production, roughly half the kingdom's output and 5 percent of global supply.
Then
Oil prices spiked nearly 15 percent in a single day — the largest one-day jump since 1991. But Saudi Aramco restored most production within two weeks, and prices returned to pre-attack levels within a month.
Now
The attack exposed the vulnerability of concentrated energy infrastructure to relatively cheap drone and missile strikes. It demonstrated that sophisticated air defenses could be bypassed and that the margin for disruption in global oil markets was thinner than assumed.
Why this matters now
The 2019 attack showed that Iranian-linked forces could temporarily disrupt Saudi oil production with precision strikes. In 2026, Iran is executing that same playbook at far greater scale — hitting facilities across multiple Gulf states simultaneously, while also closing the strait itself.
