Oil benchmarks extended rally on Tuesday as focus remains heavily anchored on the closure of Saudi Arabia's strategic East-West pipeline following recent drone attacks.
Front-month West Texas Intermediate futures gained 1.2% to $102.64 per barrel, while Brent futures were up 1.1% to $106.85/bbl.
"Brent crude trades higher as the Saudi pipeline shutdown intensifies supply concerns," Saxo Bank analysts said.
The critical line which bypasses the Strait of Hormuz could take weeks to restore, potentially cutting Saudi export volumes by 3.5 million to 4 million barrels per day, market experts have said.
"An initial press report, citing two regional representatives, stated that it could take weeks for the pipeline to be brought back into operation," Commerzbank analysts said.
Analysts from Rystad Energy warn that the prolonged outage threatens broad market undersupply, echoing earlier intraday highs following strikes on regional military infrastructure.
On the geopolitical front Ukraine has attacked new targets in Russia, including an oil refinery in Syzran, Ukraine's president said, a day after US President Donald Trump claimed both the countries had agreed to avoid strikes on each other's energy targets.
In a social media post on Tuesday, Ukrainian President Volodymyr Zelensky said Ukrainian forces had also targeted a drone manufacturing facility in Taganrog and a drone launch site in the Oryol region, along with targets in the Black Sea.
Geopolitical friction continues to severely strain shipping lanes and domestic processing networks.
Strait of Hormuz traffic slowed to just 17 vessel crossings amid a wave of regional strikes over a two-week period, pushing crude tanker freight rates to historic highs.
At the same time, domestic US balances tightened further, with Strategic Petroleum Reserve inventories ticking down to 285 million barrels, data showed.
Meanwhile, US Interior Secretary Doug Burgum reportedly said export restrictions will not lower energy prices but will risk retaliation against import-dependent refining markets like California, several media outlets reported Monday.
