"We anticipate that OPEC will stick with its official production target of 30 million barrels per day," said a report from Commerzbank in Frankfurt. "Saudi Arabia and the other Arab Gulf states see no reason for the moment to comply with the demands of individual OPEC states to implement measures aimed at shoring up prices. Thus the oversupply on the oil market will remain in place for the time being."
In April, OPEC's output averaged 30.46 million barrel a day.
