Hormuz Oil Prices Rise as Inventory Math Takes Over

Hormuz oil prices climbed again on Wednesday after Iran fired missiles toward Kuwait and Bahrain, with Brent crude at $97.05 a barrel and West Texas Intermediate at $94.77. The June 3 move kept crude below April’s panic highs, but it came with U.S. stockpiles drawing down and the Gulf’s bypass routes still too small for a clean workaround.

The fourth month of the crisis has pulled the market away from a single war-premium trade and into a daily test of physical barrels. Refiners now have to price failed missiles, delayed cargoes, lower stocks and the next diplomatic headline in the same session.

The Missile Barrage Added a Dollar

Reuters market data put Brent futures up $1.05, or 1.09%, at $97.05 a barrel, while U.S. West Texas Intermediate (WTI, the U.S. crude benchmark) rose $1.01, or 1.08%, to $94.77. The move followed accounts from U.S. Central Command (CENTCOM, the command that oversees U.S. forces in the Middle East) that two Iranian ballistic missiles fired toward Kuwait either fell short or broke apart, and three missiles launched toward Bahrain were intercepted by U.S. and Bahraini air defenses.

CENTCOM said its forces later struck an Iranian military ground control station on Qeshm Island. The current volley followed a similar pattern to the May 28 CENTCOM statement, which said Iran had fired a ballistic missile toward Kuwait hours after one-way attack drones near the strait were intercepted.

Iran’s Islamic Revolutionary Guard Corps (IRGC, the force controlling much of Tehran’s missile and drone program) claimed U.S. bases in Kuwait were hit. Kuwait’s army said air defense units responded to hostile aerial threats after explosions were heard in different parts of the country, while CENTCOM said no U.S. personnel were injured in the barrage.

Ninety-Six Days Changed the Oil Trade

Counting Feb. 28 as day one, June 3 is the 96th day of the disruption that began when the United States and Israel launched strikes on Iran. Oil has traded through several stages since then: the first shock, the April squeeze and the late-May retreat as diplomats talked through intermediaries.

The U.S. Energy Information Administration (EIA, the statistical arm of the Energy Department) put hard numbers on the physical loss in its May Short-Term Energy Outlook. The agency assessed that Iraq, Saudi Arabia, Kuwait, the United Arab Emirates (UAE), Qatar and Bahrain collectively shut in 10.5 million barrels per day of crude production in April. It also said Brent reached $138 a barrel on April 7 and averaged $117 for April.

EIA’s May forecast assumed the strait would remain effectively closed until late May, with traffic beginning to pick up in June. Wednesday’s missile exchange arrived at the front edge of that assumed recovery window. Shipping fixtures, insurance rates and naval notices will decide how much of that assumed recovery reaches cargo schedules.

The Bypass Routes Are Too Small

The International Energy Agency (IEA, the Paris-based energy security agency) says the route carried 20 million barrels per day of crude oil and oil products in 2025, around 25% of world seaborne oil trade, in its Strait of Hormuz oil security profile. The IEA also says only Saudi Arabia and the UAE have operating crude export routes that avoid the waterway.

The EIA Hormuz chokepoint analysis puts the 2024 flow at 20 million barrels per day, about 20% of global petroleum liquids consumption. It estimated about 2.6 million barrels per day of available Saudi and UAE pipeline capacity for a disruption, while the IEA range is 3.5 to 5.5 million barrels per day.

Available capacity on alternative export routes is limited.

The IEA used that line for the detour problem. A failed missile still leaves shippers checking route availability, insurance, buyer acceptance and government clearance.

U.S. Inventories Became the Shock Absorber

The American Petroleum Institute (API, the U.S. oil industry group whose inventory estimate lands before government data) estimated a 6.8 million-barrel crude draw for the week ended May 29, according to market data providers. It was the seventh weekly decline in a row and followed a 2.8 million-barrel draw the prior week.

The official government check was scheduled for June 3. The EIA petroleum release schedule says weekly petroleum summary data are released after 10:30 a.m. Eastern on Wednesday, with the full PDF and HTML tables after 1:00 p.m. Eastern.

• Refiners need crude for summer gasoline output while delayed cargoes stretch delivery times.
• Trading desks watch Cushing and Gulf Coast stocks because paper barrels settle against physical delivery points.
• Government officials have fewer quiet tools when commercial stocks fall at the same time drivers enter peak travel season.

Seven weeks of draws change the tone of every diplomatic leak. A draft deal can knock dollars off futures. Refiners still need barrels in tanks before they commit to normal run rates.

Asia Carries the Longer Exposure

Asian buyers had the deepest exposure before the crisis. The IEA says China and India together received 44% of crude exports moving through the route in 2025. The EIA estimated that 84% of crude oil and condensate and 83% of liquefied natural gas (LNG, gas chilled into liquid form for tanker shipment) that moved through the strait in 2024 went to Asian markets.

Japan and South Korea appear in EIA’s top destination group for crude flows. The IEA names Bangladesh, India and Pakistan as buyers that imported almost two-thirds of their LNG through the route in 2025. It also says gas-fired generation accounted for 50% of Bangladesh’s electricity supply mix and 25% of Pakistan’s in 2024.

That is why the price risk travels farther than the Gulf coast. A stranded Qatari cargo changes the spot LNG bid in Asia, then feeds power costs for fertilizer, textiles and cooling load in countries that don’t pump oil.

Gasoline Gives Washington a Clock

The U.S. consumer channel is already visible. The EIA gasoline and diesel update put the national regular gasoline average at $4.305 a gallon for June 1, down 17 cents from the prior week but $1.178 above the year-earlier level. U.S. on-highway diesel was $5.350 a gallon, down 17.3 cents on the week and $1.899 higher than a year earlier.

Those pump prices fell while crude remained near $100, so the relief has limits. EIA’s May Short-Term Energy Outlook forecast Brent around $106 a barrel in May and June because global inventories were expected to fall by an average of 8.5 million barrels per day in the second quarter.

Diplomacy is still part of the oil price. Tehran has been reviewing proposals to end hostilities and reopen shipping, while President Donald Trump has said talks continued. Oil traders are turning every official statement into a freight question over who can sail, who insures the trip and which ports accept the cargo.

The June 3 EIA crude report for the week ended May 29 will set the next round of trading before any new statement from Tehran or Washington does.
