Oil output from the Organization of the Petroleum Exporting Countries plunged to its lowest since at least 2000 at 16.1 million barrels per day in May, amid Iran war shipping disruption in the Middle East, according to a Reuters survey on Wednesday.
Total production, which excludes that of the UAE, reflects a 1.1 mmbbls/d month-over-month decline. The UAE left the organization last month.
Iran's output saw the biggest drop, according to Reuters, after a US naval blockade that began on April 13 pushed its exports down to their lowest in at least six years in May.
Other Gulf producers, including Saudi Arabia, also posted production declines due to the effective closure of the Strait of Hormuz.
Iraq, on the other hand, was able to increase its supply due to higher domestic demand, according to sources cited by the news agency.
Other OPEC producers, Venezuela and Nigeria, raised their production, based on the survey.
The report also revealed that OPEC's May output dropped well below the 2020 COVID-19 pandemic lows when demand collapsed.
Declines were recorded despite an agreement by OPEC and its allies to raise production in May.
