OPEC oil output in May hit its lowest in more than two decades, a Reuters survey found, as a U.S. naval blockade cut Iran's exports and Iran's effective closure of the Strait of Hormuz slashed exports by other Gulf producers.
Output by the 11-member Organization of the Petroleum Exporting Countries fell by 1.06 million barrels per day month-on-month to 16.13 million bpd, the survey found.
