It would remove pricing control from OPEC. Yes A tariff.
No, it wouldn't.
Our current domestic production has removed price controls from opec. they can’t conspire to drop production, raising prices, because there are too many opec countries that need money coming in to pay their bills and need to keep selling their oil at whatever the current market price is. they won’t stop selling because they need the money. opec can’t get all the member states to go along with it because of it.
