Iran’s Hormuz Strikes Paralyze 20% of Global Oil Transit, Test Gulf Investment Thesis
Retaliatory attacks on U.S. bases following assassination of Ayatollah Khamenei have effectively closed the Strait of Hormuz, triggering insurance withdrawals and leaving 150 ships stranded—the first complete halt in the chokepoint's history.
Iran’s escalating strikes against U.S. military installations across the Persian Gulf have brought maritime traffic through the Strait of Hormuz to a near-complete standstill, disrupting roughly 20% of global oil flows and forcing a reassessment of regional stability that underpins hundreds of billions in foreign investment. Tanker traffic through the strait dropped approximately 70% before falling to near zero on March 1-2, with at least 150 ships stranded around the waterway after six U.S. service members were killed in strikes across Bahrain, Kuwait, Qatar, and the UAE.
The retaliatory campaign began hours after joint U.S.-Israeli strikes killed Iran’s Supreme Leader Ayatollah Ali Khamenei on February 28, marking the most severe disruption to energy chokepoint security since the 1980s Iran-Iraq tanker war. Unlike that conflict, the current crisis has achieved effective closure not through naval blockade but through systematic risk elevation: Insurance withdrawal is doing the work that physical blockade has not—the outcome for cargo flow is largely the same.
Insurance Collapse Triggers De Facto Closure
Major marine war risk providers including Gard, Skuld, NorthStandard, and the London P&I Club began scrapping coverage for vessels operating in the Persian Gulf, with the benchmark freight rate for Very Large Crude Carriers hitting an all-time high of $423,736 per day on Monday—a 94% increase from Friday’s close, according to CNBC.
War-risk insurance premiums for the strait increased from 0.125% to between 0.2% and 0.4% of ship value per transit in the days before strikes—an increase of a quarter million dollars for very large oil tankers, according to Wikipedia. Insurance rates could rise to 0.5% or even 1% of vessel value, marking increases of 100% to 300%, Marcus Baker of Marsh told Al Jazeera.
The physical danger is real. At least five tankers have been damaged since the conflict began, with two personnel killed—including a shipyard worker killed when the US-flagged Stena Imperative was struck, and a crew member killed aboard the Marshall Islands-flagged MKD VYOM off Oman. Two oil tankers were targeted off Oman’s coast, and 150 freight ships including many oil tankers are stalled behind the strait, per Wikipedia.
The Strait of Hormuz is 21 miles wide at its narrowest point and facilitates transit of around 20 million barrels of oil per day—roughly 20% of global seaborne oil trade—primarily from Saudi Arabia, the UAE, Iraq, and Qatar. About 30% of Europe’s jet fuel supply originates from or transits via the strait, while one-fifth of global LNG passes through the waterway.
Regional Strikes Strain Gulf Security Architecture
Iran targeted US bases in Bahrain, Kuwait, Qatar, and the UAE, with the Islamic Revolutionary Guard Corps claiming all Israeli and US military targets in the Middle East had been struck, according to Al Jazeera. The scale surprised defense analysts. Iran fired 137 missiles and 209 drones across the UAE, with Dubai’s airport—the world’s busiest for international traffic—and Kuwait’s airport also hit.
The Strait of Hormuz has been effectively shut down since Saturday, with shipping insurance firms concerned about naval attacks, reported NPR. Saudi Arabia said one of its largest oil refineries was targeted by Iranian drones, sparking a fire and temporarily shutting down production.
- The ferocity of Tehran’s retaliation has left governments and populations stunned, despite the UAE possessing one of the Middle East’s most advanced US-backed air defense systems
- Iran’s decision to retaliate across the Middle East has isolated Tehran and angered neighbors, according to three high-ranking Arab diplomats
- Escalating strikes have forced airspace closures, stranded tens of thousands of travelers, shifted schools to remote learning, and kept residents indoors to avoid falling debris
Al Udeid Air Base in Qatar—the largest US military installation in the Middle East—took a ballistic missile hit on Tuesday, with one of two missiles breaching air defenses, Qatar’s Defense Ministry confirmed to Stars and Stripes. The US naval base in Bahrain appears to have taken extensive damage, with Iran striking the headquarters of US Naval Forces Central Command as well as multiple warehouses.
Oil Markets Price in Supply Shock, Not Premium
Brent crude spiked to around $77 per barrel on Monday, briefly surpassing $82, before rising to $82.76 by Wednesday—hovering near the highest level since January 2025, according to CNN and CNBC. Analysts forecast potential rises to $100 per barrel or higher if disruptions persist.
But the relatively contained price action reflects market structure, not calm. “This is a real supply disruption, not a risk premium event. Physical barrels are being affected across crude, products, LPG, and LNG simultaneously,” wrote analysts at Kpler.
OPEC+ announced it would raise daily output by 206,000 barrels after pausing incremental production increases earlier in the year, though energy analysts don’t expect it to do much to keep prices in check if there is a sizeable disruption to oil flows. The constraint is geographical: OPEC Plus retains approximately 3.5 million barrels per day of spare capacity concentrated in Saudi Arabia and the UAE, but a significant portion cannot reach global markets if the Strait remains inaccessible.
Bloomberg reported that Iraq started shutting down operations at the Rumaila oil field on March 3 due to lack of storage space, with tankers unable to leave the strait. Patrick de Haan of GasBuddy estimates US gasoline prices will rise 10-30 cents on average in coming days, with some stations seeing increases as much as 85 cents.
| Country/Region | Key Vulnerability |
|---|---|
| Pakistan | 99% of LNG imports from Qatar/UAE |
| Bangladesh | 72% of LNG imports from Qatar/UAE |
| India | 60% of oil imports from Middle East |
| China | ~40% of oil imports pass through Hormuz |
| Europe | 30% of jet fuel supply via strait |
Foreign Investment Calculus Under Pressure
The strikes directly threaten the Gulf’s economic diversification model. Iran’s strikes have shaken the Gulf region’s image of stability and safety, which had helped it cultivate investment, draw in expatriates, and attract tourism from around the world, reported TIME.
Fires and smoke reached Dubai landmarks including Palm Jumeirah and Burj al-Arab, with Iranian Shahed drones slamming into apartment buildings in Bahrain. Dubai’s airport has remained suspended since Saturday. Airspace closures in the UAE, Qatar, Kuwait, and other Gulf States led to grounding of thousands of flights, affecting major carriers like Emirates and causing significant losses in tourism revenue.
Saudi Arabia’s Vision 2030 ambitions are particularly exposed. The Kingdom aims to reach an FDI target of 388 billion Saudi Riyal by 2030, but if current 10% annual growth rates hold, projected FDI would reach only approximately 15 billion, according to research published in MDPI. Saudi Arabia’s foreign policy shift toward rapprochement with Iran, Qatar, and Turkey stemmed from MBS realizing an adversarial approach wasn’t advancing Vision 2030—which requires billions in Foreign Investment that in turn requires predictability and calm, noted Foreign Affairs.
The UAE and Jordan expressed concern about US attacks but denounced Iran’s retaliation, with Jordan’s King Abdullah II emphasizing “the need to work towards achieving comprehensive and sustainable calm”, according to NBC News. Qatar said it “reserves the right to retaliate” against Iran, and Saudi Arabia said it will “take all necessary measures” to defend its security.
What to Watch
Insurance market reset timeline: Major insurers including Gard, Skuld, NorthStandard, the London P&I Club, and the American Club said cancellations would take effect from March 5. Trump announced the US will offer insurance through the Development Finance Corporation and said the Navy will escort tankers through Hormuz “as soon as possible”, though Lloyd’s List reported US Navy told shipping officials that naval protection “is not an immediate option” with “no availability of naval escorts and no timeline”.
Production curtailment cascade: “The lion’s share of OPEC barrels in the region could essentially become stranded assets in an extended war scenario,” RBC analyst Helima Croft wrote, noting Iraq might have to “shut in” production if it can’t access Hormuz to export. Watch for Saudi Aramco and ADNOC loading disruptions at Ras Tanura and Jebel Dhanna terminals.
Asian demand destruction: China, India, Japan, and South Korea account for nearly 70% of crude oil shipments through Hormuz. China’s LNG inventories stood at 7.6 million tons at end-February, providing short-term cover, but China would need to compete for Atlantic cargoes if outage persists, according to CNBC.
Gulf sovereign exposure: Monitor credit default swap spreads for UAE, Qatar, Saudi, and Bahraini sovereign debt. The Dow Jones Industrial Average fell over 400 points on March 2, with broader economic forecasts warning of inflationary pressures and slowed global growth if conflict prolongs. Any sustained widening signals foreign capital reassessing regional allocation—the real test of whether decades of petrodollar recycling into Western asset management can withstand kinetic risk at the source.
