In a stark contrast to the oil shock in which the price of crude oil skyrocketed, the price of crude oil has plummeted recently. Based on WTI (West Texas Intermediate), the price of crude oil from June, 2014 to Jan, 2016 declined from 105.2 dollars per barrel to 32.6 dollars per barrel, a 69% decline. This phenomenon is believed to have been caused by OPEC’s deliberate overproduction. It seems illogical for countries in the Middle East to produce oil beyond the market’s demands since it is clear as day that the price of oil will drop, making them suffer from deficits.
