In March 2021, a cargo ship named Ever Given departed Malaysia for the Netherlands, but high winds pushed it sideways across the Suez Canal in Egypt. For six days, the blockage trapped over 400 vessels and halted an estimated $9 billion to $10 billion in global trade daily. The United States government had immediately issued the event a national security and economic crisis and offered direct military and technical assistance, because the Suez Canal serves as a critical choke point for both global commerce and American military operations. A prolonged shutdown threatened to cripple the US economy and disrupt national security.
If a single wedged container ship could hold hostage $10 billion in daily trade and throw global supply chains into chaos, it was merely a rehearsal for the catastrophic effect delivered by the closure of the Strait of Hormuz.
Unlike the Suez Canal situation, where stranded ships can ideally round Africa, the Persian Gulf exports have no immediate alternative route. While Ever Given blocked supply chains of goods, the Hormuz Strait closure halts over 20 million barrels of oil per day, instantly spiking global consumer crude prices and triggering widespread manufacturing halts. But the Suez Canal blockage was an accident, so how could a strait be otherwise “closed,” and more importantly, why?
The Strait of Hormuz effectively closed following the outbreak of US-Israeli military strikes on Iran on February 28, 2026. The United States and Israel began military campaigns to neutralize its nuclear weapons program and aggressive regional actions, after concluding that they had exhausted all diplomatic means. The initial wave targeted Iran’s top political and military command structures. This resulted in the death of Supreme Leader Ayatollah Ali Khamenei and several high-ranking officials, to destabilize the clerical regime.
The Islamic Revolutionary Guard Corps (IRGC) retaliated against the US-Israeli air campaign by laying sea mines, deploying attacks on merchant ships, and issuing strict military warnings that forbade unauthorized passage. Restricting the flow of roughly a fifth of the world’s oil and liquefied natural gas served as Iran’s primary economic and geopolitical counter-pressure against military aggression and subsequent US naval blockades. Controlling Hormuz offers Iran a deterrent and a source of revenue. By closing the strait, Iran has demonstrated it can ward off the world’s most powerful military. By monetizing it, Iranian officials believe they could generate up to $40 billion a year, roughly the same amount as the country’s annual oil export revenues in recent years.
By April 7, the United States and Iran agreed on a temporary ceasefire, though intermittent strikes and enforcement persisted. But less than 2 weeks after the ceasefire, Iranian officials rapidly reversed the brief announcement of reopening, in response to President Donald Trump’s administration pushing forward with a naval blockade against Iranian ports six days after the initial ceasefire and conflicting interpretations of the agreement. The U.S. Navy subsequently seized an Iranian cargo vessel, and the IRGC consequently captured several foreign container ships, heightening industry tensions over authorized transit corridors.
On June 14, 2026, Pakistani Prime Minister Shehbaz Sharif assisted in brokering an agreement framework between the U.S. and Iran. The memorandum of understanding (MOU) was signed 3 days later by both presidents. The agreement aimed at facilitating discussions and ending hostilities included a temporary 60-day arrangement for safe commercial passage through the strait at no charge, a lifting of certain U.S. naval blockades, and a 60-day window to address Iran’s nuclear program.
The 60-day M.O.U. has ended on August 17 in a political stalemate without reaching any conclusion of agreement. Iran laid out strict conditions for officially reopening the strait, including the U.S. lifting its naval blockade and sanctions; the U.S. must also withdraw from around Iran, pay it reparations for war damages, and release frozen Iranian assets and end its attacks.
“The strait is open, and the oil prices are coming down, and they will continue to come down unless we decide to do something more drastic than what we’ve been doing,” Trump says in a statement. However, experts disagree.
Matt Smith, director of Commodity Research at Kpler, a leading firm tracking tanker movements, says that the Trump administration seems to be “just pulling a number out of the air.”
“The reality is that Iran has the leverage, Iran has the control,” he said. “The only tankers that are really passing through the Strait of Hormuz are those that are operating through Iranian waters.”
Yet Energy Secretary Chris Wright refutes this statement, claiming that more oil is flowing through the strait than trackers account for, and that only the Trump administration has the accurate data on oil transport, because “ours aren’t estimates we have the actual data.”
“The best strategy for the United States could be patience, avoiding a return to all-out war and buying time to rally the world to oppose Iran’s claims and invest in assets that weaken Hormuz as a chokepoint,” Council of Foreign Affairs writes. The global crude available each day directly influences the logistics of consumer goods; thus, a lack of the former will inflate consumer prices, as likely already noted by most consumers. Consumers must follow supply chain realities, budget and anticipate inflation, and conserve energy, to effectively plan and manage personal financial impacts.
