With regard to market fundamentals, there have been no changes in demand and supply conditions that explain the scale of the unanticipated jump in oil prices. Moreover, the actual behavior of oil prices is consistent with speculation.
关于市场基本面，在需求和供应条件中没有明显的变化能够解释未曾预料到的油价上涨幅度。而且，油价的实际表现和投机行为一致。在六月份，油价在一天内上涨了11美元，在七月份又在三天内下跌了15美元。这样的波动不符合由基本面驱动的市场。
