I believe I read that original article which was written by an economist from the CME Group. Apparently there is a cost to production which may be higher in the US than in the desert overseas, but these domestic producers can continue to sell at a loss because they are still producing cash-flow to the business to cover debt. If they stopped pumping, they would have no cash-flow to cover debts and lose more money. I have a feeling producers here as well as in the middle east are not concerned about keeping prices up and will continue to bolster production as fast as possible. It may be a race to the bottom.
