The Strait of Hormuz has suddenly become the epicenter of one of the most severe global energy crises in recent history.
As of March 12, 2026, this narrow waterway separating Iran from Oman and serving as the primary exit route for Persian Gulf oil exports remains effectively closed amid escalating military conflict between Iran, the United States, and Israel.
The crisis traces back to late February 2026, when joint U.S.-Israeli airstrikes, dubbed Operation Epic Fury, targeted Iranian military installations, nuclear facilities, and key leadership figures.
The strikes resulted in the death of Iran’s longtime Supreme Leader, Ayatollah Ali Khamenei, triggering a rapid succession and a dramatic shift in Tehran’s posture. Iran’s Islamic Revolutionary Guard Corps (IRGC) responded with widespread retaliatory missile and drone attacks on U.S. bases across the region, Israeli targets, and energy infrastructure in neighboring Gulf states. By early March, Iran declared the Strait of Hormuz off-limits to commercial traffic, warning that any vessel attempting passage would face attack.
In his first public statement since succeeding his father, the newly appointed Supreme Leader Mojtaba Khamenei declared on March 12 that the strait would “remain closed” as a “tool of pressure” against the U.S. and Israel. Read aloud on Iranian state television, the message emphasized that the blockade would continue unless hostilities cease and U.S. military presence in the region ends. Khamenei also called on neighboring countries to expel U.S. and Israeli ambassadors and close American bases used in the strikes.
The impact on global shipping has been immediate and devastating. Prior to the conflict, the Strait of Hormuz handled approximately 20 million barrels per day (mb/d) of crude oil and petroleum products in 2025, accounting for roughly one-fifth to one-quarter of the world’s seaborne oil trade and a significant portion of liquefied natural gas (LNG). Around 80% of this volume was destined for Asian markets, with China receiving the largest share (nearly 38% of exports transiting the strait in early 2025 data).
Maritime tracking data shows traffic has plummeted from an average of over 150 vessel transits per day to just a handful, with many ships now stranded outside the strait or rerouting at enormous cost. Automatic Identification System (AIS) reports indicate only about 13 daily transits on average since early March, and even those are limited and high-risk. Multiple commercial vessels, including tankers and cargo ships, have been struck by drones, missiles, or projectiles in recent days. Incidents on March 11 alone involved at least three to six ships, including the Thai-flagged Mayuree Naree (which caught fire, leading to crew evacuation and missing mariners), ONE Majesty, and Star Gwyneth. British maritime monitoring groups and the UK Maritime Trade Operations (UKMTO) have logged over a dozen attacks or suspicious incidents in the Persian Gulf, Strait of Hormuz, and Gulf of Oman since late February.
Iran has escalated further by deploying naval mines, with reports confirming about a dozen laid in recent days. U.S. Central Command (CENTCOM) responded by destroying at least 16 Iranian mine-laying vessels, but experts warn that heavier mining could render the strait impassable for months. Former military officials note that Iran possesses thousands of small boats and asymmetric assets capable of swarming commercial traffic, making any reopening effort extremely hazardous. One analyst remarked that Iran “only needs to be lucky once” to inflict major damage.
The economic fallout has been swift. Brent crude prices have surged past $90–$100 per barrel, with some forecasts warning of spikes toward $200 if the closure persists. The International Energy Agency (IEA) announced plans to release emergency oil reserves, an unprecedented move to mitigate supply shocks. Global supply chains face ripple effects beyond oil: disruptions threaten fertilizers, metals, and other commodities reliant on Gulf shipping. Asian economies, heavily dependent on the strait, are hit hardest, while even China, despite diplomatic efforts to secure safe passage, has seen its tankers trapped or halted.
The U.S. military has so far declined requests to escort civilian vessels through the strait, citing unacceptable risks in the narrow, confined waters. Defense officials describe current conditions as too dangerous for routine convoy operations. Proposals for international naval escorts, floated by leaders like French President Emmanuel Macron, remain conceptual at best. Retired naval officers warn that attempting to force passage without a ceasefire would expose ships to “suicidal” threats from shore-based missiles, drones, and mines.
Iran’s strategy appears calibrated: selective disruptions and threats preserve leverage without completely halting its own limited oil exports (which have paradoxically increased slightly in recent days via high-risk transits). Yet the broader blockade has amplified pressure on global energy markets and raised fears of a prolonged energy crisis.
As the conflict enters its third week, the Strait of Hormuz stands as a stark reminder of the fragility of global energy security. With no immediate diplomatic breakthrough in sight and military actions continuing, including fresh Israeli strikes in the region, the world watches anxiously for signs of de-escalation. For now, the chokepoint remains choked, and the price of oil and stability continue to rise.
