据彭博社纽约12月21日消息，尽管有关欧佩克减产和页岩油产量飙升的说法不绝于耳，但石油最大的问题是对经济的恐慌，其中相关分析证明了这一点。
在2014年的上一次油价暴跌期间，普氏500指数和布伦特原油走势相反。石油价格的下跌未能证明对美国股市造成太大拖累，反之亦然，两种资产之间的强负相关系数为0.65。
这种情况在大宗商品当前暴跌期间发生了变化。布伦特原油和普氏指数走势一致：两者相关系数转为正值并进一步增强至强劲的0.75。
沃尔夫研究公司分析师萨姆•马戈林周四在一份报告中写道：“欧佩克无法解决这一困境。”解决方案只取决于围绕全球增长的市场信心。”
尽管沃尔夫在认为2019年将出现“建设性”的迹象，但只有这些迹象转向更广泛的情绪，他们才会转化到石油。
