昨日，原油期货价格再次大涨，截至北京时间凌晨3点03分, 美国西得克萨斯原油期货价格上涨1.92美元, 5.35%至37.86, 伦敦商品期货交易所布伦特原油期货价格上涨2.05美元, 5.29%至40.77美元。
虽然各项数据显示国际原油市场供给过剩与需求不足仍然较为严重，但油价不畏所惧一度反弹。西得克萨斯原油价格自2月份地位至今涨幅达31.8%。那么油价大涨的背后到底是哪些因素的推动力?
美元下跌是油价反弹的直接原因
美元自2月份开始出现下行趋势, 美元指数由2月份高位99.70下跌至目前97.12,跌幅达2.6%. 以美元为计价的原油自2月份开始出现反弹，由最低28.74美元一路反弹至昨日最高38.11美元,反弹幅度达31.8%。
不仅是原油, 其他大宗商品价格也呈现大幅反弹态势, 黄金(1267.20)自2月份至今反弹幅度达13.72%; 铜(5720.50)价自2月份反弹至今, 涨幅达13.4%。
由于美联储对于其是否按计划实现加息进程表现迟疑, 美元自2月份高位回撤. 美元相对于其他货币与黄金的下跌, 会直接影响到以美元为计价的各种大宗商品价格的走势. 美元相对于其他货币便宜了, 自然会导致油价的上涨。
产油大商品对原油产量进行冻结
油价上涨的另一个基本面原因是个产油国对于集体达成原油减产协议的努力。首先由沙特阿拉伯发起，联合俄罗斯、奎瓦特与委内瑞拉在2月16日达成协议将联合原油产量进行冻结。3月20日至4月2，欧派克国家将在此举行会议对原油产量问题继续探讨以支撑原油价格。
另外，根据美国能源信息署数据，截至2月26日，美国原油产量连续减少第六周至908万桶/日，是自2014年以来最低水平。美国石油勘探公司阿帕奇公司（Apache Corp.）上个月称其原油产量在2016年将下降11%；Continental Resources Inc. 将可能减产10%，Whiting Petroleum Corp. 预计减产15%。
对冲基金与投机交易员放弃空头, 补入多头
另外对冲基金与投机交易的多头回补是油价上涨的真正推动力。据彭博社统计，截至3月1日，近期对冲基金与投机交易减少西得克萨斯原油原油期货空头头寸数量达15%。投机交易空头头寸降低至25639张合约，期权合约数量将至150718张。是4月21日以来最大的数量缩减。同时多头合约数量达24886张。
目前的情况来看， 市场对于油价抄底的情绪高涨， 油价有望进一步反弹。
