据能源世界网11月24日新加坡报道，布伦特原油价格触及自3月以来最高位，因第三种有前景的冠状病毒候选疫苗的消息，激发了石油需求加速复苏的希望。

格林尼治时间07：44时，布伦特原油期货上涨45美分，至每桶46.51美元，涨幅为1%;美国西德克萨斯中质原油上涨46美分，至每桶43.52美元，涨幅为1.1%。

本周二早些时候，布伦特原油价格上涨至46.72美元，创下3月初以来的最高水平，此前沙特阿拉伯与俄罗斯发起了价格战，导致油价暴跌。在上周上涨约5%之后，这两个基准石油价格周一收盘上涨约2%。

金融服务公司Axi的首席全球市场策略师斯蒂芬·英尼斯（Stephen Innes）表示，开发和分发疫苗的进展降低了石油市场回归正常的风险。如果流动性数据可以衡量油价的走势，那么在不久的将来，疫苗将使人们重返飞机和游轮上。

阿斯利康(AstraZeneca)周一表示，该公司生产的新冠疫苗在关键试验中有70%的有效性，而且可能高达90%，这为世界抗击这场全球新冠疫情提供了第三种新武器，与竞争对手相比，这种疫苗的制造成本更低、更容易分发和推广速度更快。在此之前，辉瑞/BioNTech和Moderna的试验都取得了积极的结果。

周一路透社提前于美国石油协会和能源信息署（EIA）的报告公布其初步调查显示，上周美国原油库存可能小幅下降，而馏分油库存连续第10周下降。

贸易商们还关注着欧佩克及其盟友为期一周的技术会议，为下周的部长级会议做准备。由于新冠肺炎疫情第二波爆发，需求疲软，下周的部长级会议将讨论延长石油产量限制至明年的问题。

Brent hits highest since March, spurred by coronavirus vaccine hopes

Brent crude prices hit their highest levels since March as news of a third promising coronavirus vaccine candidate spurred hopes of a quicker recovery in oil demand.

Brent crude futures rose 45 cents, or 1per cent, to $46.51 a barrel by 0744 GMT, while U.S. West Texas Intermediate crude added 46 cents, or 1.1per cent, to $43.52.

Brent rose to a session high of $46.72 earlier on Tuesday, the highest level traded since early March before Saudi Arabia initiated a price war with Russia, which sent oil prices crashing. Both oil benchmarks settled up about 2per cent on Monday after gaining about 5per cent last week.

"Progress on developing and distributing a vaccine de-risks the path back to normal for oil markets," said Stephen Innes, chief global markets strategist at financial services firm Axi.

"If mobility data is a measure of oil price sentiment, in the not too distant future, the vaccine will get people back on airplanes and cruise ships."

AstraZeneca said on Monday its COVID-19 vaccine was 70per cent effective in pivotal trials and could be up to 90per cent effective, giving the world's fight against the global pandemic a third new weapon that can be cheaper to make, easier to distribute and faster to scale-up than rivals.

This follows positive trial results from Pfizer/BioNTech and Moderna.

U.S. crude oil inventories likely edged lower last week, while distillate stockpiles were seen decreasing for a 10th straight week, a preliminary Reuters poll showed on Monday, ahead of reports from the American Petroleum Institute and the Energy Information Administration (EIA).

Traders also focused on a week of technical meetings by OPEC and its allies to prepare the ground for next week's ministerial gathering, which is set to discuss extending oil output curbs into next year due to weak demand amid a second wave of COVID-19.
