Hormuz Crisis 2026: U.S. Oil Surges Past $90 as Global Supply Shock Deepens

The 2026 Strait of Hormuz crisis has driven U.S. crude oil above $90 a barrel and American gas prices to $3.41 a gallon as Iran's blockade chokes roughly 20% of the world's seaborne oil supply.

The 2026 Strait of Hormuz crisis, now in its third month as of May 28, has delivered the largest disruption to global energy supply since the 1970s oil crises, with West Texas Intermediate and Brent crude holding well above $90 per barrel as diplomatic efforts continue to falter and Iran maintains its stranglehold on the world's most critical maritime choke point. The crisis, rooted in the U.S.-Israeli military offensive against Iran launched on February 28, has rewritten the energy price map for 2026 and sent global oil markets into a prolonged state of structural shock.

How the Crisis Erupted: Operation Epic Fury and the Strait's Closure

The trigger for the current crude oil price surge was Operation Epic Fury — coordinated U.S.-Israeli airstrikes on Iran's military, nuclear, and leadership infrastructure on February 28, 2026. The strikes resulted in the death of Supreme Leader Ali Khamenei and the rapid designation of a new, more hardline leadership under Mojtaba Khamenei, Khamenei's son with deep ties to the Islamic Revolutionary Guard Corps (IRGC).

Iran's response was swift and economically devastating. Within hours of the strikes, the IRGC transmitted warnings via VHF radio prohibiting any vessel from transiting the Strait of Hormuz. By March 2, an IRGC senior official formally confirmed the waterway was closed and threatened to set ablaze any ship that attempted passage. Tanker traffic — which ordinarily carries roughly 20 million barrels of oil per day, or approximately 20% of global seaborne crude oil — collapsed to near zero. Over 150 ships anchored outside the strait to avoid IRGC drone boats, missiles, and newly planted naval mines.

The economic fallout was instantaneous. Brent crude jumped 10–13% on the first trading day of March. By March 8, oil prices surpassed $100 a barrel for the first time in four years, and Brent reached its peak of $126 a barrel days later — a price level not seen since 2022. The largest single-month oil price increase in market history was recorded in March 2026, with Brent gaining 51% in four weeks.

$90 Oil and the American Consumer: Gas Prices Surge to $3.41

The immediate pressure point for U.S. consumers arrived in the form of surging retail gasoline prices. The national average for a gallon of regular gasoline jumped 14% in a single week to $3.41, according to AAA data — the sharpest weekly increase since the Russia-Ukraine war in March 2022. California prices exceeded $5 per gallon by the second week of March.

The U.S. crude West Texas Intermediate benchmark, closely tied to domestic pump prices, remains elevated above $90 as supply disruptions persist. Analysts from Goldman Sachs and Barclays have highlighted that the $90+ floor could hold as long as the Strait remains functionally closed. The last time crude was at comparable levels, national average U.S. gasoline prices reached $3.80 per gallon — a threshold the market is now approaching rapidly.

President Trump, who campaigned heavily on energy affordability, dismissed concerns about rising prices in a Reuters interview, saying: "They'll drop very rapidly when this is over, and if they rise, they rise." Treasury Secretary Scott Bessent responded by issuing a 30-day waiver on U.S. sanctions targeting the sale of Russian crude to India in a bid to free up stranded supply volumes.

2,000 Ships Stranded: The Scale of the Supply Shock

The scale of the disruption has no modern parallel in oil market history. As of mid-May, the International Maritime Organization reported approximately 20,000 mariners and 2,000 vessels stranded in the Persian Gulf due to the Hormuz closure. Saudi Aramco CEO Amin Nasser confirmed on May 11 that over 600 tankers are trapped inside the Gulf, with an additional 240 waiting on the other side of the strait.

Gulf oil-producing nations have suffered severe output contractions. Production at Iraq's Rumaila oil field — one of the world's largest — was shut down by March 3 due to lack of tanker exit capacity. Kuwait Petroleum Corporation declared force majeure on March 7. QatarEnergy suspended gas production and declared force majeure on gas contracts. Saudi Arabia cut crude output by 20% from 10 million barrels per day to 8 million barrels per day by mid-March after Iranian drone strikes hit two of Aramco's offshore fields, including the Safaniya field. Total Middle East oil exports dropped at least 60% by March 15, from 25 million barrels per day to roughly 10 million.

The combined pipeline bypass capacity — Saudi Arabia's East-West Crude Oil Pipeline to Yanbu, the UAE's Abu Dhabi Crude Oil Pipeline to Fujairah, and Iraq's Kirkuk-Ceyhan line — totals only about 9 million barrels per day, less than half of the strait's normal daily crude throughput.

A Dual Blockade: U.S. and Iran Lock Horns Over the Waterway

The crisis deepened significantly on April 12, when the Islamabad Talks — direct U.S.-Iran negotiations in Pakistan — collapsed without agreement. President Trump immediately declared a U.S. naval blockade of Iranian ports, effective April 13, creating what observers described as a "dual blockade": Iran blocking the Gulf and the U.S. Navy blockading Iranian ports. The situation prompted Russia and China to veto a Bahrain-led UN Security Council resolution on April 7 that had sought international coordination to restore freedom of navigation.

A brief ceasefire window on April 17 produced a temporary 11% drop in crude prices when Iran's Foreign Minister Abbas Araghchi announced the Strait fully open to commercial shipping. The relief lasted less than 24 hours. Iran reimposed restrictions the following day after the U.S. maintained its naval blockade, with gunfire reported on Indian-flagged tankers within hours of the announcement.

On May 4, Trump launched Operation Project Freedom — a U.S. Navy escort mission for commercial ships attempting to exit the Gulf — but suspended the operation two days later amid reports of renewed diplomatic engagement. The IRGC has since redefined the Strait of Hormuz as a broader "operational area" extending from Jask to Siri Island, effectively expanding the zone of hostility.

Global Ripple Effects: Fertilizer, Helium, and European Gas

The Hormuz blockade has cascaded well beyond oil. European natural gas prices surged from €30/MWh before the crisis to above €60/MWh by early March — nearly double in days — before partially retreating. Europe accelerated imports of Russian Yamal LNG, receiving 91 cargoes from the project between January and April 2026, accounting for 98% of the facility's exports during that period.

Fertilizer markets face a parallel shock. The Gulf region produces nearly half the world's urea and 30% of its ammonia, with roughly one-third of internationally traded fertilizers normally transiting the Strait. Urea prices climbed 50% from pre-war levels by late March. Helium distributors began rationing deliveries in early April as Qatar's LNG disruption — which accounts for one-third of global helium production — strained critical supply chains. Aluminum prices ticked higher as Bahrain's ALBA smelter, the world's largest, cut output.

The International Energy Agency's 32 member states unanimously agreed on March 11 to release 400 million barrels of emergency reserves — roughly four days of global consumption — as an immediate price stabilization measure.

Market Outlook: $80–$90 Floor Even After Resolution

Commodity Context founder Rory Johnston stated that any sustained reopening of the Strait would trigger an immediate $10–$20 drop in crude prices due to speculative positioning, but warned that supply chain bottlenecks, infrastructure damage, and persistent production outages would keep the market tight.

"This is still the largest oil supply shock in the history of the oil market," Johnston said, noting that a sustained restoration of flows is needed before any lasting price relief materializes. The base case among Wall Street energy desks has anchored Brent in the $80–$90 range even in a resolution scenario — far above pre-crisis levels near $72 a barrel.

As of May 28, 2026, with diplomatic talks resuming and Operation Project Freedom paused, the Strait of Hormuz remains effectively closed to Western commercial traffic. The structural damage to global energy supply chains, combined with the depth of Middle Eastern production outages, suggests that $90+ crude will remain a market reality through the foreseeable future — regardless of how quickly the geopolitical standoff is resolved.
