EMEA crude futures advanced in after-hours trading on Tuesday as markets weighed mounting risks to supplies from the Middle East and Russia, with attacks on Saudi energy infrastructure and Russian refineries adding to concerns over an already tight global energy market.
Brent crude futures climbed 2.3% to $108.13 per barrel, while Dubai 1st Line Futures advanced 2.1% to $104.69/bbl.
The Middle East conflict has widened over the past weeks, with Iran-backed Houthis attacking Saudi energy facilities and Gulf Arab states postponing planned discussions with Iran.
Saudi Arabia has reportedly halted oil loadings at its Red Sea port of Yanbu, and the country has informed European customers that some late-September crude cargoes would be canceled.
The Gulf state issued security alerts over a range of territory, including Mecca and Jeddah, on Tuesday. The Saudi Arabian Civil Defense later lifted the alerts, saying the danger had passed in Jeddah, Abha, Jazan, AlUla and Taif amid an uptick in attacks by the Houthis.
The latest strikes followed a Houthi attack on Saudi Arabia's East-West Pipeline on Friday that forced the Gulf state to shut the vital export route.
Kpler strategists said that damage to Saudi Arabia's East-West Pipeline has shifted the oil market's focus to export logistics, with the key question now how quickly the Gulf state can restore flows and reroute crude.
Kpler's base case assumes the Petroline will return at about 50% of its pre-attack capacity after repairs that could take as long as six weeks. The consultancy said that could reduce exports from the Red Sea port of Yanbu by about 2.5 million to 2.7 million barrels per day.
Fueling bullish sentiment, Libya's National Oil Corporation said operations at three oil fields were suspended after protesting members of the Petroleum Facilities Guard shut a valve on the Hamada-Zawiya crude export pipeline.
The state oil company said it may declare force majeure if the valve remains closed or if additional fields are forced to halt production, as the Guard warned the shutdown could expand if its demands are not met, according to media reports.
Meanwhile, Ukraine said on Tuesday it hit the Syzran refinery in Russia's Volga region overnight, as Kyiv attacks on refineries in Russia have helped drive diesel prices to record highs.
The attacks came after the two sides welcomed a potential energy truce floated by President Trump. Ukrainian President Volodymyr Zelenskyy proposed that his country's partners secure an agreement with Russia to stop the destruction of critical infrastructure.
Dan-Bunkering strategists said that Ukrainian attacks have reduced Russian refinery output and product availability, and there is little reason to assume this pressure will disappear.
On the supply front, commercial traffic in the Strait of Hormuz dwindled further on Tuesday after attacks intensified in the Middle East. The latest data from Windward showed that eight vessels crossed the Hormuz, comprising six inbound and two outbound transits.
