OIL CHOKEHOLD: Tehran Grabs The Wheel

Iran proved it can shut down one of the world’s most critical oil routes — and U.S. intelligence now says Tehran can do it again whenever it wants.

Story Snapshot

Iran effectively closed the Strait of Hormuz after U.S. and Israeli strikes on February 28, 2026, sending oil prices up nearly 70% this year.
U.S. Central Command says it has degraded Iran’s ability to attack ships, but traffic through the strait remains far below normal.
U.S. intelligence agencies now assess that Iran can shut down the strait at will, giving Tehran a powerful new weapon against the global economy.
About 2,000 ships remain stuck in the Gulf, and the U.S. says mine-clearing operations could take up to six months to complete.

The World’s Most Important Oil Chokepoint

The Strait of Hormuz sits between Iran and Oman. It connects the Persian Gulf to the Arabian Sea. About 20% of the world’s oil and liquefied natural gas moves through this narrow passage every year. The U.S. Energy Information Administration notes that very few alternate routes exist if the strait closes. About 3,000 ships used to pass through each month — until this year’s conflict changed everything.

After the United States and Israel launched strikes on Iranian nuclear sites on February 28, 2026, Iran’s Islamic Revolutionary Guard Corps declared the strait closed and threatened to fire on any ship that tried to pass. Iran also deployed sea mines across the shipping lanes. Tracking data showed tanker traffic dropped by 70% almost immediately. Brent crude oil prices surged to around $119 per barrel. Qatar declared force majeure on liquefied natural gas shipments.

Iran’s Tactics and Selective Control

Iran did not simply block all ships equally. The Islamic Revolutionary Guard Corps used speedboats, missiles, drones, satellite jamming, and mines to control who could pass. Iran charged tolls of over $1 million per ship for vessels it deemed friendly — mainly from India, Pakistan, Turkey, and China. Ships linked to the U.S., Israel, or Western allies were turned away or threatened. At least 21 ships were struck or targeted between March 1 and March 18 alone.

Iran’s government claimed a legal right to do this. In a March 2026 statement, Iran’s Ministry of Foreign Affairs said it was applying what it calls the “innocent passage” framework, arguing it can block any vessel it views as a security threat. The U.S. rejects that legal argument, but analysts note Iran has some room to contest international shipping rules because it never ratified the 1982 United Nations Convention on the Law of the Sea.

America Fights Back — But the Threat Remains

U.S. Central Command has not stood still. Admiral Brad Cooper announced that U.S. forces bombed an underground weapons facility on Iran’s coastline that stored anti-ship cruise missiles and mobile missile launchers. Defense Secretary Pete Hegseth said the U.S. blockade against Iran is “impenetrable” and claimed 125 million barrels of oil had already left the Gulf. Central Command stated flatly: “Iran does not control the Strait of Hormuz.”

Iran created leverage by making the Strait itself a cost center for global capital. The blockade and sanctions regime were tolerable to Washington so long as the costs were borne mainly by Iran. Once the conflict threatened the circulation of oil, shipping, insurance, Gulf state…

But the reality on the water tells a more complicated story. U.S. intelligence agencies now assess that Iran can shut down access to the strait at will, even after a ceasefire or deal is reached. Around 2,000 vessels remain stuck in the Gulf waiting to move. The Pentagon told Congress that clearing the mines Iran allegedly laid could take up to six months — and that work likely cannot begin until fighting stops. Insurance premiums for ships in the area have jumped from a fraction of a percent of a ship’s value to nearly 5%. Even Vice President JD Vance has acknowledged the goal is to get the strait open “in a toll-free way for the long term,” signaling the U.S. knows this fight is far from over. Iran has shown the world it holds a powerful new card — and it will not be easy to take away.
