The U.S. and Israeli conflict with Iran has once again transformed the Strait of Hormuz into a geopolitical flashpoint, bringing international shipping to a virtual standstill in this critical maritime passage.
Nearly all traffic has ceased in this vital waterway connecting the Persian Gulf to global oceans, effectively shutting down a crucial artery for the world’s oil supply. Attacks on commercial vessels and threats of further military action have deterred tankers from transporting oil, gas, and other commodities through the strait. This disruption has forced some of the world’s largest oil producers to reduce output as their crude oil accumulates with nowhere to go.
This is not the first time the Strait of Hormuz has been weaponized in regional conflicts. Previous incidents of ship seizures and military confrontations have alarmed commercial shipping companies and disrupted maritime traffic. Iran has repeatedly threatened to close the strait during periods of heightened sanctions and tensions, though it has historically stopped short of completely halting all passage. Even amid the current conflict, maritime tracking data shows dozens of vessels have managed to navigate through the waterway.
While both Iran and Oman hold territorial claims in the Strait of Hormuz, the narrow shipping channels are internationally recognized as open waters accessible to vessels from all nations. Nevertheless, Tehran wields considerable influence over the passage due to its military presence in the region and its control of strategic islands nearby.
The current conflict, now in its third week following U.S. and Israeli strikes on Iran that resulted in the death of Iran’s supreme leader, has sent shockwaves through global energy markets. Before the war erupted, approximately one-fifth of the world’s oil supply traveled through the Strait of Hormuz. The resulting supply constraints have triggered sharp increases in fuel prices worldwide.
Historical disruptions to the strait have followed a pattern of threats, limited closures, and economic repercussions. During the Iran-Iraq “Tanker War” of the 1980s, both nations attacked vessels in and around the strait, deploying naval mines that periodically halted traffic. The U.S. Navy became directly involved in the conflict, including a one-day battle with Iranian forces in 1988 and the tragic mistaken downing of an Iranian commercial airliner that killed 290 civilians. Despite these hostilities, the strait never completely closed, though shipping became extremely hazardous and disrupted.
In late 2011 and early 2012, Iran threatened to close the strait in response to Western sanctions targeting its nuclear program. The European Union implemented a ban on Iranian oil purchases, while the U.S. imposed restrictions on the country’s energy sector and financial institutions. Though Iran eventually walked back its threats without closing the waterway, the uncertainty caused significant volatility in oil markets, with Brent crude prices exceeding $100 per barrel for much of 2012 and reaching peaks above $126.
Similar threats emerged in 2018 when then-U.S. President Donald Trump withdrew from the Obama-era nuclear agreement with Iran and reimposed sanctions. Despite Iranian President Hassan Rouhani’s renewed threats to close the strait, Iran again refrained from doing so. Oil markets experienced volatility but ultimately stabilized, with Brent crude ending the year at around $54 per barrel.
Between 2019 and 2025, the strait witnessed numerous ship seizures and attacks. The U.S. Navy attributed several limpet mine attacks on vessels near the strait to Iran, including a fatal drone strike on an Israeli-linked oil tanker in 2021—allegations Tehran denied. These incidents drove up insurance rates and created significant concerns for shipping companies. Iran also seized several foreign vessels, including oil tankers accused of smuggling fuel, a Portuguese-flagged cargo ship in 2024, and two Greek tankers that were detained for months in 2022.
During the brief 12-day war between Israel and Iran in 2025, concerns about a potential closure of the strait intensified, particularly after U.S. intervention with bombing campaigns against Iranian nuclear and military installations. Despite these tensions, Iran did not close the strait, and oil prices, after an initial spike, actually declined as traders doubted the likelihood of widespread attacks on oil shipments.
The current situation represents one of the most severe disruptions to this crucial maritime chokepoint in recent history, with significant implications for global energy security and economic stability as the conflict continues to unfold.
