据路透社12月15日报道，周二，原油价格突破每桶50美元，原因是新冠肺炎疫苗的上市带来了乐观情绪，抵消了欧洲市场进一步实行限制措施和需求复苏放缓的预期。
随着美国因新冠肺炎死亡人数超过30万，美国于周一开始为民众接种疫苗。英国和加拿大也开始实施疫苗注射。
格林威治标准时间10：51，布伦特原油价格上涨14美分，至每桶50.43美元，涨幅0.3%。美国西德克萨斯中质原油(WTI)价格上涨14美分，至每桶47.13美元。
受需求复苏希望的支撑，过去几周油价有所回升，布伦特原油价格在12月10日达到每桶51.06美元，为3月以来最高水平。要知道3月份，随着新冠肺炎疫情的蔓延，油价跌至历史低点。
德国商业银行(Commerzbank)分析师卡斯滕•弗里奇(Carsten Fritsch)表示：“布伦特原油继续无视所有负面消息，不过，随着欧洲越来越多的国家和美国各大州都在圣诞节和新年期间实施限制措施，这可能会对需求造成压力。”
伦敦加大了出行限制，要求关闭酒吧和餐馆；意大利正在考虑在圣诞节期间采取更严格的措施；德国可能在2021年初之前都处于封锁状态。
预测机构也在削减需求预期。国际能源署(IEA)周二表示，疫苗对需求的影响还需要几个月的时间。欧佩克曾表示，石油需求增长将慢于预期。
石油经纪商PVM的塔马斯•瓦尔加(Tamas Varga)表示:“各预测机构之间越来越一致的看法是，全球石油需求的改善可能不会从明年年初开始，而是将在明年下半年开始。”
美国石油供应的最新数据显示出好坏参半的局面，汽油和馏分油库存上升，而原油库存下降。

Oil rises above $50 as vaccine optimism counters new
Oil rose above $50 a barrel The United States began vaccinating people Brent crude rose 14 cents, or 0.3% to $50.43 a barrel at 1051 GMT. U.S. West Texas Intermediate (WTI) crude was up 14 cents at $47.13.
Oil has recovered in the past few weeks, with Brent reaching $51.06 “Brent is continuing to defy all the negative news,” said Carsten Fritsch, analyst at Commerzbank. “More and more countries in Europe and states in the U.S. are tightening the corona restrictions over Christmas and the new year, which is likely to weigh London stepped up pandemic restrictions requiring bars and restaurants to close, Italy is considering more stringent steps over Christmas and Germany is likely to be under lockdown until early 2021.
Forecasters are also trimming demand numbers. The International Energy Agency “There is a growing agreement between forecasting agencies that the improvement in global oil demand might not start at the beginning of next year but in the second half,” said Tamas Varga of oil broker PVM.
The latest snapshots of U.S. oil supplies are expected to show a mixed picture, with gasoline and distillate stocks rising and crude inventories falling.
