TEHRAN- The war in the West Asia is creating the biggest oil supply disruption in history, the International Energy Agency said on Thursday, a day after it agreed to release a record volume from strategic stockpiles to offset shortages and a spike in prices.

According to a report by Reuters on Friday, Global supply is expected to drop by 8 million barrels per day in March, the IEA said in its latest monthly oil market report - a volume equal to almost 8% of world demand - due to the blocking of the Strait of Hormuz, a narrow channel along the Iranian coast, since the U.S. and Israel began airstrikes on Iran on February 28.

Persian Gulf countries including Iraq, Qatar, Kuwait, the United Arab Emirates and Saudi Arabia have cut total oil production by at least 10 million barrels per day as a result of the conflict, the IEA said, adding that without a rapid restart of shipping flows these losses were set to increase.

"Shut-in upstream production will take weeks and, in some cases, months to return to pre-crisis levels depending on the degree of field complexity and the timing for workers, equipment and resources to return to the region," the agency said.
