2014至2015年国际油价趋势分析2014-11-28
2014至2015年国际油价趋势分析编者按：欧佩克部长级会议将于11月27日召开，是否以及如何应对国际油价下挫趋势将成为关键议题。为此，专家对此次会议后油价趋势做出情景分析，并预计，国际油价走弱将持续进入2015年，因为除了欧佩克政策外，供过于求的基本面难见重大变化。 自2014年7月以来，布伦特原油价格持续走低，尤其是在11月中旬跌至80美元/桶以下，为2006年以来首次进入70美元警示区。目前，国际能源署、欧佩克(OPEC)和花旗银行等金融机构预计，这一跌势有可能继续下跌至70~60美元新谷底。笔者根据油价分析框架和近期国外交流，对此次国际油价趋势、动因和影响做如下分析。 基本面分析 自2014年以来，国际石油市场供应与需求出现明显不平衡。供大于求的特征十分突出，是下半年国际油价下跌的基本原因。 从地区结构看，在北美地区，美国石油产量上升和进口规模缩减为最大供应变量。根据FGE全球能源咨询公司的数据，2014年美国的原油及液体产量不断提升，全年预计达到每日1150万桶，比上年增加近140万桶/日。同期美国的石油(原油与油品)净进口量预计递减20%，全年石油对外依存度由2013年的32%降至26%。在加拿大，由于项目投资巨大，投资期限较长，成本结构受油价变化影响不一。目前该国油砂项目产量增势未减，主要既有油砂项目仍在运作。 其次，在西亚北非地区，利比亚的石油产量从6月份的24万桶/日开始，44万桶/日、55万桶/日、78万桶/日，一直上升到10月的86万桶/日，与其他OPEC 产油国的稳产和降势形成鲜明对比。利比亚的石油产量持续恢复增长提高了对欧洲炼厂的出口水平。伊拉克战乱后，伊拉克的石油产量一直维持在306万桶/日上下，没有出现预期的大幅上升势头，但是过去四个月的石油出口规模有所增长(达到255万桶/日)。主要由于上述两个国家的出口推动，使得下半年以来的欧
