Despite the oil market’s size, speculation can move prices because of the inelasticity of demand and supply. Oil demand is slow to change because of behavioral inertia and fixed technology, while adjusting production takes time.
尽管石油市场的规模很大，但是由于需求和供应的刚性，投机就可以改变价格。因为行为惯性以及技术限制，同时调整石油产量也需要时间，所以石油需求的变化很慢。这些特征使石油市场易于受到投机的影响。
