An export ban would place the maximum American crude price at about $70/barrel, since that's a little bit above the shale breakeven price. Prices would tank overnight. There is no conceivable scenario where an export ban would not substantially cut oil prices. Maybe we won't see $2/gallon again, but $6+/gallon would be a thing of the past.
