Such speculative purchases may barely register in inventories, because the purchases are small compared to the overall market, and because of the global storage system’s many margins of accommodation. As a result, speculatively driven high prices can persist for a considerable time before economic fundamentals bring them down, as finally seems to be happening.
因为投机性的购买和整个市场相比是很小的，而且全球的石油库存体系有许多需要调适的空白地带，这样的购买几乎不可能登记在库存中。因此，在基本面使油价回落——正像最终发生的那样——之前，由投机驱动的高油价能够持续一个相当长的时间。
