Oil futures were mixed on Thursday as progress in talks between Iran and Oman muddied sentiment amid persistent security threats and supply concerns linked to the ongoing closure of the Strait of Hormuz.
Brent was up 0.9% to $88.64 per barrel, while Murban crude futures declined 3.4% to $90.56/bbl.
Iran and Qatar on Thursday discussed ways to create conditions for dialogue to de-escalate tensions in the region and the formation of a temporary joint shipping corridor through the Strait of Hormuz, Qatar's Ministry of Foreign Affairs said in a statement.
The diplomatic landscape in the Middle East shifted as Iran and Oman agreed on terms for sharing the waters and revenues of the strait, though Tehran reportedly emphasized that fully reopening the vital waterway requires broader measures.
This development aligned with statements from US President Donald Trump who said that 10 million barrels moved through the corridor in a single day and that all naval mines were cleared.
Despite these assurances, US allies reportedly said that the strait is still endangered by some of the 80 to 150 mines initially laid by Iran, and commercial vessel traffic remains well below pre-war averages amid lingering security fears.
Data from analytics firm Kpler showed just five vessels crossing the strait on August 25 down 28.6% from the previous day with all of them utilizing Iran's unilateral transit scheme.
The UK Maritime Trade Operations reported that a tanker was struck by an unknown projectile, triggering a localized fire that has since been contained.
On the supply side, the latest Energy Information Administration weekly report released on Wednesday showed that US commercial crude oil inventories increased by 100,000 barrels to stand at 428.9 mmbbls for the week ended August 21.
Meanwhile, analysts said that new US sanctions targeting Iran landed notably milder than market participants had initially feared, helping to steady sentiment as the energy sector navigates Middle Eastern supply instability.
