Dubai, May 4, 2026

Crude oil prices surged on May 4 as escalating tensions in the Strait of Hormuz and a U.S. naval blockade disrupted global supply chains, with Iran and the U.S. exchanging accusations of military provocations.

Rising Tensions and Supply Disruptions

June WTI crude oil futures rose 3.18 (+3.12%) while June RBOB gasoline futures climbed 0.1323 (+3.68%) as geopolitical risks intensified. The U.S. began a blockade of vessels passing through the Strait of Hormuz on April 13, targeting ships bound for Iranian ports. President Trump confirmed the blockade would remain in force "until a deal is fully agreed."

Iran's FARS news agency claimed "two missiles had hit a US warship," a statement swiftly denied by U.S. officials. Meanwhile, the UAE reported an Iranian drone attack caused a fire at the Fujairah oil industry zone and issued a missile threat warning after drones struck an oil tanker. Iran warned it would attack U.S. forces if they entered Hormuz, further escalating tensions.
