Iraq stepped up its push for bigger OPEC production quotas as it seeks to recoup oil sales that were lost because of the Iran war, even raising the prospect that it could consider an exit in the future.

Iraq’s oil ministry warned on Thursday that “a decision will have to be made regarding whether to remain in or withdraw” if it doesn’t receive a high enough ceiling from the Organization of the Petroleum Exporting Countries, though it said later that an exit hasn’t been proposed, and consideration of such a move isn’t the government’s official position.
