Oil was up by nearly 3 per cent on Tuesday as persistent worries about supply constraints from the closed Strait of Hormuz continued, with Brent futures for June rising by $3.03 or 2.8 per cent to $111.26 a barrel, and the US West Texas Intermediate (WTI) crude futures growing by $3.56 or 3.7 per cent to $99.93 a barrel.
An earlier round of negotiations between the United States and Iran collapsed last week after face-to-face talks failed.
Ship-tracking data showed significant disruptions in the region, with six Iranian oil tankers forced to turn back due to the US blockade, but some traffic is still moving.
Prices trimmed some of the advances after the United Arab Emirates (UAE), the fourth-largest producer in the Organisation of the Petroleum Exporting Countries (OPEC), said on Tuesday it would exit the group on this Friday, May 1, 2026.
This dealt a blow to the oil-exporting group and its de facto leader, Saudi Arabia.
The UAE could quickly add between 1 million and 1.5 million barrels per day of output. However, with the Strait of Hormuz effectively closed, analysts said that there’s nowhere for that supply to go.
The UAE joined OPEC in 1967, but tension with Saudi Arabia over production quotas has been building for years.
Under the OPEC+ deal, the country has been held to roughly 3 million barrels per day while sitting on capacity above 4 million. It has been pushing toward 5 million barrels per day by 2027, and that target is hard to achieve with quotas built around someone else’s view of the market.
The war in Yemen broke whatever was left of diplomatic patience.
President Donald Trump said he was unhappy with the latest Iranian proposal to end the war. The proposal would avoid addressing the nuclear programme until hostilities cease and Gulf shipping disputes are resolved.
The Idemitsu Maru, a Panama-flagged tanker carrying 2 million barrels of Saudi oil, and an LNG tanker managed by the Abu Dhabi National Oil Company (ADNOC) crossed the Strait on Tuesday, shipping data showed.
Vortexa data showed that the amount of crude oil held around the world on tankers that have been stationary for at least seven days rose to 153.11 million barrels as of April 24.
The American Petroleum Institute (API) estimated that crude oil inventories in the United States fell by 1.79 million barrels in the week ending April 24. The official data from the US Energy Information Administration (EIA) will be released later on Wednesday.
