Brent crude jumped 10% to about US$80/barrel over the counter on Sunday, oil traders said, while analysts predicted that prices could climb as high as $100 after US 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/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.
Oil price shock
While some alternate infrastructure could be used to bypass the Strait of Hormuz, the net impact from its closure would be a loss of 8-10 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/barrel when trade opens.
