How the Trump administration responded as the Strait of Hormuz closure impacted the global economy - CNN

Global disruption in real time
A White House scramble to contain a crisis


A timeline of how the Trump administration responded as the effective closure of the Strait of Hormuz consumed the global economy.

After the United States and Israel attacked Iran on February 28, the conflict unleashed the biggest oil supply shock in history, with the effective closure of the critical Strait of Hormuz sending energy prices sharply higher.

The Trump administration has had to craft its messaging about a war that is widely unpopular with Americans. US average gas prices climbed more than $1 per gallon in just six weeks, surpassing $4.10, the highest level since 2022.

The White House has framed the war as a necessary effort to eliminate Iran’s nuclear threat and secure long-term peace in the region. At home, however, the Trump administration is grappling with the fallout: Rising energy prices, record-low consumer sentiment and opposition to the conflict are putting a spotlight on Americans’ top concern — affordability.

Trump touts America’s "energy dominance"

President Donald Trump orders an attack on Iran, without any public signaling, while traveling on Air Force One to an event in Texas. Trump tells the crowd that "slashing energy costs" is his top priority as president. JPMorgan Chase releases its 2026 crude oil forecast at a “bearish” $60 per barrel, but notes geopolitical turmoil is a “wild card."

Military action

Operation Epic Fury is launched

The military operation begins at 1:15 a.m. EST. Trump releases a video announcement that focuses entirely on military justification, making no mention of potential economic fallout. Simultaneously, the European Union naval mission reports the first Islamic Revolutionary Guard Corps warnings to commercial vessels transiting the Strait of Hormuz.

Trump announces that Iranian Supreme Leader Ayatollah Khamenei is dead, following strikes conducted "working closely with Israel." Trump characterizes this as the "single greatest chance for the Iranian people to take back their Country" and warned the IRGC to surrender for immunity or face "certain death."

The Strait of Hormuz effectively shutters and the cost of oil immediately spikes

The global energy crisis begins in earnest as transit through the critical Strait of Hormuz drops dramatically, following four ship attacks and two reported deaths. Trump provides a military update but makes no public mention of the potential for energy price spikes.

Strait of Hormuz officially closes: Oil prices surge and the White House scrambles

Oil prices climb as Iran strikes other Gulf countries. Qatar halts production of liquefied natural gas and an IRGC official declares the Strait of Hormuz closed. White House advisers convene to monitor market reactions. Secretary of State Marco Rubio becomes the first official to acknowledge potential "economic fallout," while the White House press secretary emphasizes US insulation through domestic production and Venezuelan oil. A White House official explicitly rejects a potential Strategic Petroleum Reserve release as a policy response to suddenly surging retail gas prices.

"Unconditional surrender": Trump demands total Iranian submission

In a social media post, Trump demands Iran's "UNCONDITIONAL SURRENDER." His top economic adviser, Kevin Hassett, flatly rejects a Strategic Petroleum Reserve release, while Secretary Bessent hints at "un-sanctioning" millions of barrels of oil on the water to create supply. The US International Development Finance Corporation announces a dramatically narrowed version of its insurance plan, admitting the initial version was premature.

Trump dismisses blockade as a "choice"

Aboard Air Force One, Trump tells reporters he is "not worried" about gas prices and claims the strait is "cleaned out," despite the effective closure. US gas prices rise to $3.41 a gallon, up more than 40 cents since the war began.

"Small price to pay": Administration frames spike in cost of gasoline as necessary

Trump labels high oil prices a "very small price to pay," calling those who disagree "fools.” Secretary Wright asserts that the price spikes are driven by "fear and perception" and will only last weeks, not months.

Trump posts that "short term oil prices" are a "very small price to pay" for world safety and that "ONLY FOOLS WOULD THINK DIFFERENTLY!"

Short term oil prices, which will drop rapidly when the destruction of the Iranian nuclear threat is over, is a very small price to pay for U.S.A., and World, Safety and Peace.

$35 oil plunge: Trump optimism on Iran whipsaws global markets

Trump tells CBS the military operation is "very far" ahead of schedule and “very complete, pretty much.” His comments trigger one of the most dramatic market responses of the conflict, with oil prices tumbling from nearly $120 to below $90 per barrel, before paring some losses to settle at $98 per barrel. The optimistic rhetoric reverses an 800-point intraday drop in the Dow, which ultimately closes up 0.5%. Less noticed, however, is Trump's first threat to hit Iran "TWENTY TIMES HARDER" if they stop the flow of oil – a clear and public nod toward the rapidly growing concern inside the White House about the strait.

Administrative chaos: Phantom tweet triggers oil market whiplash

The price of oil plunges after Secretary Wright claims on X that the US Navy successfully escorted an oil tanker through the strait. The tweet is subsequently deleted and White House press secretary Karoline Leavitt confirms no vessels have been escorted "at this time." Iran's foreign minister accuses the US of "posting fake news to manipulate markets." Meanwhile, Trump says the strait is being held "hostage" and that "it doesn't really affect us," but orders his team to lobby for a joint IEA oil reserve release just hours after Wright told allies the US opposed it.

"Short-term pain": White House admits the public must suffer

Trump tells waiting ships to "show some guts," while claiming the disruption is a net positive because the US will "make a lot of money" when prices are high. In another dramatic reversal, the Treasury Department expands Russian oil sanctions relief, which Secretary Bessent describes as a "short-term and temporary disruption.” Nonetheless, oil prices climb, with Brent crude settling above $100 per barrel for the first time since 2022.

Walking away: US signals abandonment of the Strait of Hormuz

Trump signals the US may "finish off" the Iranian state and leave the strait's responsibility to the countries that use it. Vice President JD Vance offers a rare candid warning of a "rough road ahead.”

Speaking in Auburn Hills, Vance gave one of the clearest distillations of the administration’s political message: The next few weeks would be painful, but the spike was temporary and would reverse once the conflict ended.

"We're going to take care of business, we're going to come back home, and when that happens, you're going to see energy prices come back down to reality. But in the meantime, we got a problem. We know that we have a problem. We're doing everything that we can to address it….We've got a rough road ahead of us for the next few weeks, but it's temporary."

Strategic retreat: "Maximum pressure" ends to prevent meltdown

In the most unthinkable policy reversal of the conflict, the Treasury Department lifts sanctions on Iranian oil stored at sea in its latest effort to prevent a projected oil price spike to $150 per barrel. The action is the exact opposite of the “maximum pressure” strategy Bessent pledged at the start of Operation Epic Fury. It provides a financial windfall for Iran, the only country whose ships have continued through the strait unobstructed since the start of the conflict.

As of April 18, Iranian gunboats fired on a tanker trying to pass through the key waterway on Saturday and a second vessel was hit by a projectile, according to maritime authorities, after Iran’s military said it was reimposing restrictions on the strait due to “repeated breaches of trust” by the US. On April 17, the Strait of Hormuz was open to all commercial vessels for the remainder of the ceasefire, according to Iran's Foreign Minister Abbas Araghchi. Trump noted in a social media post that while the strait was now open, the US naval blockade would continue until a deal with Iran was “100% complete.” Oil prices tumbled by as much as 13%, with Brent crude dropping below $90 a barrel. US stocks rallied on the news: The Dow surged by more than 1,000 points, or 2.1%, shortly after Friday's opening bell, recouping all of its losses since the war with Iran began. The S&P 500 and Nasdaq also sharply rose, after back-to-back days of record highs on optimism that a deal would be made.
