- Iran’s Revolutionary Guard has ordered all vessels to halt passage through the Strait of Hormuz following joint U.S.-Israeli strikes on Iran, leaving roughly 150 oil and gas tankers stranded in surrounding waters as the world watches one of the most consequential energy crises in decades unfold in real time.
- The strikes, launched Saturday, February 28, reportedly killed Supreme Leader Ali Khamenei, the Islamic Republic’s foundational authority for 35 years, prompting Iran to declare 40 days of mourning and a seven-day national holiday while a leading Shiite cleric called on Muslims worldwide to wage jihad against the United States and Israel.
- Iran retaliated swiftly and broadly, launching dozens of drones and ballistic missiles at U.S. military installations across the Persian Gulf region, striking targets in Bahrain, Kuwait, Qatar, the UAE, Saudi Arabia, Iraq, and Jordan — killing and injuring dozens of people and triggering emergency evacuations across the region.
- Approximately 20 percent of the world’s daily oil supply transits the Strait of Hormuz, along with roughly a third of global seaborne crude exports and a significant portion of the world’s liquefied natural gas — with China, India, Japan, and South Korea among the nations most dependent on the route and no viable maritime alternative available.
- Brent crude settled near $73 per barrel on Friday before the strikes, but Barclays analysts warned Sunday that markets could be facing their “worst fears” on Monday’s open, projecting Brent could reach $100 per barrel as the market processes the full scale of the supply threat — a price level not seen in years.
- Major shipping companies have already pulled out of the region, with Hapag-Lloyd suspending all Strait of Hormuz transit, Maersk diverting vessels around the Cape of Good Hope, and CMA CGM ordering ships already inside the Persian Gulf to seek shelter immediately — a near-total commercial abandonment of the world’s most vital shipping lane.
- The aviation sector has been thrown into chaos, with Qatar Airways, Lufthansa, British Airways, Air France, Air India, Turkish Airlines, and others suspending Middle East service, while Dubai International Airport — the world’s busiest international hub — was shut down entirely following a reported Iranian strike on the facility Saturday.
- Energy analyst Robert McNally of Rapidan Energy Group warned that a prolonged Strait closure is a guaranteed global recession, describing the potential for “the mother of all bidding wars” among major Asian importers scrambling to secure supply, with oil prices forced high enough to trigger an economic contraction severe enough to reduce demand.
- The warning signs were visible well before Saturday’s strikes, with Iranian gunboats attempting to seize a U.S. tanker in early February, Iran seizing two foreign oil tankers near Farsi Island days later, and a live-fire military drill on February 17 that briefly closed the Strait for hours — a pattern of deliberate escalation that in hindsight reads as preparation for exactly this moment.
- The path forward hinges on who is now in control inside Iran and how far the Trump administration is willing to push, with the Islamic Republic’s leadership structure thrown into uncertainty following Khamenei’s reported death, while the administration has signaled it may tap the Strategic Petroleum Reserve if prices spike — though analysts warn that reserve capacity and alternative pipeline routes can absorb only a fraction of normal Strait traffic.
The narrow corridor of water between Iran and Oman just became the most consequential stretch of ocean on earth. In the hours following joint U.S. and Israeli military strikes on Iran Saturday, the Islamic Republic’s Revolutionary Guard Corps began broadcasting radio warnings to shipping vessels that passage through the Strait of Hormuz was prohibited — effectively announcing a blockade of the world’s most critical oil chokepoint.
As of Sunday morning, at least 150 oil and gas tankers sat idle in the surrounding waters, unable to move, as energy markets braced for what analysts are already calling a potential worst-case scenario for global supply.
The strikes, launched on Saturday, February 28, represent the most dramatic military escalation in the Middle East in a generation. President Trump confirmed the operation in a video posted to Truth Social, announcing that the United States had launched strikes on Iran alongside Israel.
Israeli Defense Minister Israel Katz framed the action as a preemptive strike to neutralize Iranian threats. The operation reportedly targeted key military and leadership infrastructure, and by Sunday, Iran confirmed that Supreme Leader Ali Khamenei had been killed in the strikes. Iran declared 40 days of mourning and a seven-day national holiday. A leading Shiite cleric has since called for Muslims to wage jihad against the United States and Israel in retaliation.
Tehran’s response was swift and sweeping. Iranian forces launched dozens of drones and ballistic missiles across the Persian Gulf, striking U.S. military bases in Qatar, Kuwait, Bahrain, Jordan, Iraq, Saudi Arabia, and the United Arab Emirates. An Iranian drone struck the Crowne Plaza Hotel in Manama, Bahrain, triggering fires and emergency evacuations. A drone was intercepted near the Etihad Towers complex in Abu Dhabi, with debris causing minor injuries.
Iranian attacks reportedly killed one person and injured 32 in Kuwait, and killed three more while injuring 58 in the UAE. Iranian missiles also targeted British military installations in Cyprus, though UK Defense Secretary John Healey indicated the bases were not believed to have been directly attacked. Separately, Yemen’s Houthis announced they would resume attacks in the Red Sea — compounding an already strained global shipping environment.
The Strait of Hormuz is only 21 miles wide at its narrowest point, with usable shipping lanes measuring just two miles in each direction. Despite its compressed geography, it is indispensable. According to the U.S. Energy Information Administration, approximately 20 million barrels of oil transited the strait every day in 2024 — roughly a third of the world’s total seaborne crude exports.
About 20 percent of global liquefied natural gas exports pass through it as well, with the majority originating in Qatar. Three-quarters of those barrels flow to China, India, Japan, and South Korea. China alone receives half of its crude imports through the Strait. There is no maritime alternative. There are no bypass pipelines capable of absorbing even a fraction of that volume. When the Strait closes, the global energy market does not reroute — it freezes.
A European Union naval mission official told Reuters that vessels in the region were receiving maritime VHF transmissions from Iran’s IRGC stating clearly: “No ship is allowed to pass the Strait of Hormuz.” The United Kingdom Maritime Trade Operations authority acknowledged on Sunday that while no formal closure had been communicated through official maritime safety channels, there was “ongoing regional military activity contributing to elevated threat to commercial shipping.”
UKMTO also reported two vessel incidents off the coast of Oman — one ship struck by an unknown projectile that resulted in a brief fire in the control room, and a second vessel that was fully evacuated. German shipping group Hapag-Lloyd has suspended all vessel transit through the Strait until further notice. Maersk confirmed it is diverting services around the Cape of Good Hope. CMA CGM has instructed vessels already inside the Persian Gulf to proceed immediately to shelter.
Oil prices had settled near $73 per barrel for Brent crude on Friday, before any of this unfolded. Analysts from Eurasia Group told Reuters that if the conflict persisted through Sunday, prices were likely to rise $5 to $10 above that baseline based on Iran’s closure claims alone. Barclays analysts issued a sharper warning, telling Reuters that “oil markets might have to face their worst fears on Monday,” and that Brent could hit $100 per barrel as markets grapple with the threat of actual supply disruption.
Robert McNally of Rapidan Energy Group, quoted by CNBC, did not mince the math: “A prolonged closure of the Strait of Hormuz is a guaranteed global recession.” He warned of hoarding by major Asian importers and what he called “the mother of all bidding wars” once the market fully processes what a sustained closure would mean. “Oil prices would have to rise high enough to trigger an economic downturn that reduces demand to balance the market,” he said. “There just isn’t enough discretionary or elastic demand for oil.”
The economic ripple effects extend far beyond fuel prices. Airlines have already begun pulling flights across the region. Qatar Airways, Lufthansa, Air France, British Airways, Air India, Turkish Airlines, Kuwait Airways, and others have suspended or canceled services to the Middle East for varying durations. Dubai International Airport — the world’s busiest for international passenger traffic — was shuttered after a reported Iranian strike sent passengers evacuating through smoke-filled corridors on Saturday. Bahrain, Iraq, Israel, Kuwait, Qatar, and the UAE have closed their respective airspaces entirely. The aviation sector faces compounding pressure both from direct security risks and from the fuel-price shock now working its way into forward markets.
Tensions between Washington and Tehran have been building for months, marked by escalating confrontations at sea, mass anti-regime protests inside Iran, and a series of failed nuclear negotiations. As far back as early February, six IRGC Navy gunboats attempted to seize a U.S. tanker in the Strait, only to be turned back by the USS McFaul. Days later, Iran seized two foreign oil tankers near Farsi Island.
On February 17, during nuclear talks in Geneva, Supreme Leader Khamenei threatened that Iran was “capable of sinking” U.S. warships in the area. The Strait was briefly closed for hours that same day during an Iranian live military fire drill — a dress rehearsal that drew little attention at the time but looks considerably more significant in hindsight. The strikes on Saturday came just two days after U.S.-Iranian nuclear talks ended without agreement, following repeated public warnings from President Trump that military action was on the table if Iran refused to accept a new nuclear deal.
The question now hanging over energy markets, governments, and shipping firms alike is how long this disruption lasts and how far it escalates. Iran has the military tools to make the Strait genuinely dangerous — mines, short-range missiles, drone swarms, and a coastline that hugs the northern shore of the waterway. Even short of a full naval blockade, Tehran can raise the cost of transit to the point where insurers refuse to underwrite tanker voyages and shipowners opt for self-preservation over commerce.
The Trump administration has indicated the Strategic Petroleum Reserve could be tapped if prices spike, and Saudi Arabia and the UAE each have limited pipeline capacity that bypasses the Strait entirely — the Saudis via an east-to-west pipeline to the Red Sea, the Emirates via a line terminating at the Gulf of Oman. But those alternatives can absorb only a fraction of normal traffic. Analyst Muyu Xu from Kpler noted Sunday that an oil tanker had already been struck off the coast of Oman, signaling what appears to be “a clear escalation of the conflict and a shift in targets from purely military facilities to energy assets.”
Ali Vaez, director of the Iran Project at the International Crisis Group, told Al Jazeera that the calculus for global markets is unforgiving: “Closure of the Strait of Hormuz would disrupt roughly a fifth of globally traded oil overnight — and prices wouldn’t just spike, they would gap violently upward on fear alone. The shock would reverberate far beyond energy markets, tightening financial conditions, fueling inflation, and pushing fragile economies closer to recession in a matter of weeks.”
Currency markets may also experience acute volatility. During a comparatively brief Iran conflict in June of the previous year, the U.S. dollar fell roughly one percent before recovering. The scale of the current confrontation is considerably more severe.
What unfolds in the coming days will be shaped by who is making decisions inside Iran right now. Khamenei, the regime’s foundational authority for 35 years, is dead. The Islamic Republic’s Supreme National Security Council has publicly framed the U.S.-Israeli strikes as a “brutal air operation” carried out against a nation that was still engaged in negotiations, calling the action “cowardly.” Iranian Foreign Minister Abbas Araghchi called the attacks “wholly unprovoked, illegal, and illegitimate.”
But not everyone inside Iran is grieving. Videos reported by The Daily Telegraph and Iran International showed people inside the country celebrating the strikes — hopeful, in the words of observers, that they represent the beginning of the end for a government that has brutally suppressed its own population for decades. North Korea has condemned the operation as “illegal aggression.” The international diplomatic fallout is only beginning.
For the United States and its allies, the immediate task is managing a confrontation that has simultaneously removed Iran’s most powerful leader, triggered Iranian retaliation across the Persian Gulf, and placed the world’s most critical oil transit route in a state of effective siege. The administration’s energy policy, the Federal Reserve’s inflation calculus, the stability of Asian economies dependent on Gulf oil — all of it now runs through a 21-mile strait that Iran is currently telling the world it controls.
Monday’s market open will be the first real-time verdict on whether investors believe that threat is sustainable, or whether the display of force by the United States and Israel has fundamentally changed what Iran is capable of enforcing. Either way, the days ahead will determine whether this becomes a contained crisis or a turning point in the global energy order.
