Oil prices jump 6% as Iran sets UAE oil port ablaze, strikes vessels in Strait of Hormuz

May 05, 2026 News

(Reuters) – Oil prices jumped about 6% on Monday as Iran stepped up attacks on the United Arab Emirates and ships in the Middle East Gulf the past 24 hours, the most serious escalation since a U.S.-Iran ceasefire came into force in early April.

Brent futures rose $6.27, or 5.8%, to settle at $114.44 per barrel, while U.S. West Texas Intermediate (WTI) crude rose $4.48, or 4.4%, to settle at $106.42.

Iran hit several ships in the Strait of Hormuz on Monday and set a UAE oil port ablaze, as President Donald Trump’s attempt to use the U.S. Navy to free up shipping provoked the war’s biggest escalation since a ceasefire was declared four weeks ago.

The UAE said its air defenses were engaging missile and drone threats on Monday evening as firefighters battled a blaze at a major oil industry zone following a drone attack that authorities said had originated from Iran.

The U.S. military said it destroyed six Iranian small boats and intercepted Iranian cruise missiles and drones fired by Tehran as it sought to thwart a new U.S. naval effort to open shipping through the Strait of Hormuz.

Iran’s Revolutionary Guards Navy, meanwhile, issued a map that it said was expanding the areas controlled by Iran near the Strait of Hormuz to include the UAE’s ports of Fujairah and Khorfakkan as well as the coast of Umm Al Quwain emirate in the UAE, according to Iranian news agencies.

About 20% of global oil and liquefied natural gas supplies passed through the strait before the U.S. and Israel launched strikes against Iran on February 28.

“Oil will remain above $100 and U.S. gasoline prices will reach $5 a gallon by June … without a deal to reopen Strait of Hormuz,” analysts from consultancy Eurasia Group said in a note. Motorists in California were already paying $6 a gallon for gasoline.

Earlier in the day, the U.S. military said two U.S. merchant ships had made it through the strait, without saying when. Iran denied any crossings had taken place.

VESSELS ATTACKED IN THE GULF

Iran may have attacked four ships in the Gulf region over the past 24 hours, including vessels from South Korea and the UAE.

There was a fire and an explosion on a vessel operated by South Korean shipper HMM 011200.KS, opens new tab in the on Monday, the foreign ministry in Seoul said.

The UAE accused Iran of attacking an empty crude oil tanker belonging to Abu Dhabi state oil firm ADNOC with drones as it attempted to transit the Strait.

The United Kingdom Maritime Trade Operations (UKMTO), meanwhile, said it received a report of an incident involving a cargo vessel about 36 nautical miles north of Dubai. The UKMTO also reported a separate incident earlier in the day near the UAE.

Separately, the energy minister in the UAE, which left OPEC last week, said the country owes it to its investment partners to produce what global oil markets require without restrictions, while cooperating with other crude producers.

OPEC and its allies, known as OPEC+, said they would raise oil output targets by 188,000 barrels per day in June for seven members, marking the third consecutive monthly increase.
