原油库存对油价有很大的影响吗
关键词：原油库存对油价有很大的影响吗
前段时间，由于OPEC坚持不减产，使得原油价格持续走软，这说明原油的供给对油价的影响是十分大的。我们常常看到的一些原油库存数据也能显示原油的供给量变化，那么，它又是否会对油价造成很大的影响呢？
大田小编告诉您，会的！因为，原油的供应量与需求量产生较大差异时，油价会因此发生改变。一般而言，供应量过剩，油价会下跌；供应量减少，油价会上涨。也就说原油库存数量一般与油价成负相关关系。
举个例子，9月16日公布的美国上周EIA原油库存减少210.4万桶，预期为增加120万桶，由于出现意外下滑，原油价格在数据公布后出现反弹。
再来看多一个例子，9月2日公布的美国上周EIA原油库存减少466.7万桶，出现了大幅增多，反映出当前原油供应量大幅上涨，从而对油价构成了较大了利空，拉大了油价的跌幅。
如果这两个数据不能说服您，那么您再看下表小编统计的数据，此为近几周美国EIA原油库存公布数据以及当时原油价格的变化。
| 周期 | 公布值 | 油价变化 |
| 2015/9/11当周 | -210.4 | 1.57 |
| 2015/9/4当周 | 257 | -0.91 |
| 2015/8/28当周 | 466.7 | -1.98 |
| 2015/8/21当周 | -545.2 | 0.99 |
| 2015/8/14当周 | 262 | -1.52 |
| 2015/8/7当周 | -168.2 | 0.59 |
此外，通过小编研究发现，一般在库存增加时，油价几乎都是表现为即刻下跌的行情，而当库存表现为减少时，油价很多时候是一个冲高回落再反弹的过程。比如说8月12日和8月26日公布的8月7日当周和8月21日当周原油库存数据时油价的走势。
因此，总的来说，原油的库存变化对油价的影响时很大的，所以，各位投资原油的朋友在数据公布时可以把握入场时机。
