LONDON, March 1 (Reuters) – Brent crude jumped 10% to about $80 a barrel over the counter on Sunday, oil traders said, while analysts predicted ​that prices could climb as high as $100 after U.S. ‌and Israeli strikes on Iran plunged the Middle East into a new war.

“While the military attacks are themselves supportive for oil prices, the key factor here is the closing of the Strait of Hormuz,” said Ajay Parmar, director ‌of ​energy and refining at ICIS.

Most tanker owners, oil ⁠majors and trading houses ⁠have suspended crude oil, fuel and liquefied natural gas shipments via the Strait of Hormuz, trade sources said, after Tehran warned ships against moving through the waterway. More than 20% of ​global oil is moved through the Strait of Hormuz.

“We expect prices to open (after the weekend) much closer to $100 a barrel ⁠and perhaps exceed that level if ⁠we see a prolonged outage of the Strait,” Parmar ​said.

Middle East leaders have warned Washington that a war on Iran ​could lead to oil prices jumping to more than $100 ‌a barrel, said RBC analyst Helima Croft. Barclays analysts also said prices could hit $100.

The OPEC+ group of oil producers agreed on Sunday to raise output by 206,000 barrels per day (bpd) from April, a ⁠modest increase representing less than 0.2% of global demand.

While some alternate infrastructure could be used to bypass the Strait of Hormuz, the net ⁠impact from its ‌closure would be a loss of 8 million ⁠to 10 million bpd of crude oil supply ​even ‌after diverting some flows through Saudi Arabia’s East-West ​pipeline and ⁠Abu Dhabi pipeline, said Rystad energy economist Jorge Leon.

Rystad expects prices to rise by $20 to about $92 a barrel when trade opens.

The Iran crisis also prompted Asian governments and refiners to assess oil stockpiles and alternative shipping routes and supplies.
