Crude production under the collective Organisation of the Petroleum Exporting Countries (OPEC ) fell in May to its lowest level in at least 37 years as the blockade of Iran by the United States and disruptions in the Persian Gulf, continued to limit output.
According to a Bloomberg survey released on Friday, output from the organisation’s 11 current members, including Nigeria, dropped by 1.22 million barrels per day to 16.33 million barrels per day last month.
Iran accounted for more than half of the decline. The data excludes the United Arab Emirates (UAE), which departed the cartel last month after six decades of membership.
War between a US-Israeli alliance and Iran has reduced oil supplies from the Middle East, largely closing the Strait of Hormuz waterway. Saudi Arabia, Iraq, the UAE and Kuwait have been forced to cut crude production. Iranian shipments face additional pressure following a US blockade of its ports imposed in mid-April.
Iranian output fell by 710,000 barrels per day to a five-year low of 2.34 million barrels per day in May, the survey showed. Central Command reported that US forces have redirected 127 commercial vessels to enforce the blockade of all maritime traffic entering and exiting Iranian ports.
Kuwait recorded the second-largest decline last month, with production falling by 310,000 barrels per day to 490,000 barrels per day, less than one-fifth of pre-war levels. Saudi Arabia, the group’s leader, saw output decrease by 240,000 barrels per day to 6.57 million barrels per day.
The production reductions have not prevented OPEC and its allies from raising quotas over recent months, continuing a year-long process of restoring output halted several years ago.
This comes ahead of a meeting scheduled to be held on Sunday, June 7, where a sub-group of seven members is expected to increase targets by 188,000 barrels again in July. The session is one of four online meetings OPEC and its partners plan to hold that day.
Delegates indicated the alliance has plans for two additional monthly quota increases in August and September. UAE output rose by 300,000 barrels per day to 2.44 million barrels per day in May, according to the survey.
