據世界石油2月18日報道，油價兩個月來首次出現周跌。

隨著從天然氣到金屬和食品的大宗商品價格在西方和俄羅斯之間的僵局中每一次轉變而波動，西得克薩斯中質原油周五收于每桶91美元附近。美國原油本周下跌2.2%。

盡管最近一段時間油價走高，但近期的漲勢已顯示出降溫的跡象。北海市場的原油價格差距有所縮小，而煉油利潤率面臨壓力。一家專注于石油的交易所交易基金遭遇了自2020年7月以來的最大單日撤資。

西得克薩斯中質油的即期價差(與它最接近的兩種合約之差)降至86美分，遠低于本周早些時候的2美元溢價。利差收窄表明，在出口減弱的情況下，交易員預計下月供應緊張程度將有所緩解，3月原油期貨將于周二到期。

原油價格本周升至2014年以來的最高水平，在需求高漲、供應緊張和庫存下降的支撐下，原油價格大幅上漲。是近年來最強勁的潛在市場之一，布倫特原油期貨價格觸及每桶100美元。雖然市場仍然強勁，但由于地緣政治風險溢價在過去幾天下降，價格已經走弱。

價格：

紐約3月交割的WTI下跌69美分，收于每桶91.07美元。

4月布倫特原油價格上漲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.
