据世界石油2月18日报道，油价两个月来首次出现周跌。

随着从天然气到金属和食品的大宗商品价格在西方和俄罗斯之间的僵局中每一次转变而波动，西得克萨斯中质原油周五收于每桶91美元附近。美国原油本周下跌2.2%。

尽管最近一段时间油价走高，但近期的涨势已显示出降温的迹象。北海市场的原油价格差距有所缩小，而炼油利润率面临压力。一家专注于石油的交易所交易基金遭遇了自2020年7月以来的最大单日撤资。

西得克萨斯中质油的即期价差(与它最接近的两种合约之差)降至86美分，远低于本周早些时候的2美元溢价。利差收窄表明，在出口减弱的情况下，交易员预计下月供应紧张程度将有所缓解，3月原油期货将于周二到期。

原油价格本周升至2014年以来的最高水平，在需求高涨、供应紧张和库存下降的支撑下，原油价格大幅上涨。是近年来最强劲的潜在市场之一，布伦特原油期货价格触及每桶100美元。虽然市场仍然强劲，但由于地缘政治风险溢价在过去几天下降，价格已经走弱。

价格：

纽约3月交割的WTI下跌69美分，收于每桶91.07美元。

4月布伦特原油价格上涨57美分，收于每桶93.54美元。

Oil posts first weekly loss since December as rally cools off

Oil posted its first weekly loss in two months as traders weighed heightened geopolitical tensions . 

West Texas Intermediate closed down near $91 a barrel on Friday. U.S. crude fell 2.2% this week, fluctuating as prices of commodities from gas to metals and food swung with every twist and turn in the standoff between the West and Russia. 

Even with its most recent leg higher, oil’s recent rally has shown signs of cooling. The North Sea market has seen differentials for physical barrels ease, while refining margins have come under pressure. One oil-focused exchange-traded fund saw its biggest daily withdrawal since July 2020. 

WTI’s prompt spread--the difference between its nearest two contracts-- dropped to 86 cents, down sharply from its $2 premium earlier this week. The narrower spread signals that traders expect supplies to be somewhat less tight next month amid muted exports. March crude futures expire on Tuesday.

Crude rose to the highest since 2014 this week in a blistering rally underpinned by roaring demand, constrained supply, and declining inventories. The underlying market is one of the strongest its been in years, and Dated Brent, a more immediate measurement of oil prices, hit $100 a barrel. While the market remains strong, prices have weakened as the geopolitical risk premium has declined in the past few days. 

Prices:

WTI for March delivery fell 69 cents to settle at $91.07 a barrel in New York.

Brent for April rose 57 cents to settle at $93.54 a barrel.
