据彭博社8月13日新加坡报道，由于风险资产的抛售加剧了贸易紧张局势，削弱了需求前景，抵消了美国原油库存预计下降的影响，石油价格三日内都出现了上涨。

在过去三天上涨7.5%后，纽约期货价格下跌了0.8%。亚洲股市下跌，美元走强，使得以美元计价的大宗商品对投资者的吸引力降低。根据彭博社周三发布EIA数据之前的调查估计，美国原油库存上周可能下降了约230万桶。

本月迄今为止，油价仍下跌逾6%，原因是人们担心贸易战将升级，需求下降，这掩盖了对中东能源流动可能中断的担忧。俄罗斯能源部在一份声明中表示，俄罗斯的目标是为了石油市场的利益，进而继续与欧佩克合作。该部补充称，贸易争端日益增加的不确定性正在产生影响。

截至伦敦时间上午8:08，西德克萨斯中质原油9月份交割价格下跌0.33美元，至每桶54.60美元，跌幅0.6%。该合约周一上涨0.43美元，收于54.93美元，为8月2日以来的最高收盘价。

在洲际期货交易所布伦特原油10月结算价格下跌0.39美元，至58.18美元，跌幅0.7%。在过去两个交易日上涨4.1%后，该合约周一收盘时变化不大。同月，全球基准原油对WTI的溢价为3.66美元。

Oil snaps three-day gain as selloff counters crude inventories

Oil snapped a three-day gain as a sell-off in risk assets added to lingering trade tensions to dent the demand outlook, countering a forecast decline in U.S. crude stockpiles.

Futures slid as much as 0.8% in New York after rising 7.5% the past three days. Asia stocks fell, while the dollar firmed, making commodities priced in the U.S. currency less attractive to investors. American inventories probably dropped by about 2.3 MMbbl last week, according to the median estimate in a Bloomberg survey before Energy Information Administration data Wednesday.

Oil is still down more than 6% so far this month as fears the U.S.-China trade war will escalate and dent demand overshadow concerns energy flows from the Middle East may be disrupted. Russia aims to continue its cooperation with the Organization of Petroleum Exporting Countries in the interests of the oil market, the nation’s energy ministry said in a statement, adding that growing uncertainties about the trade dispute is having an impact.

West Texas Intermediate crude for September delivery fell $0.33, or 0.6%, to $54.60/bbl on the New York Mercantile Exchange as of 8:08 a.m. London time. The contract advanced $0.43 to settle at $54.93 on Monday, the highest close since Aug. 2.

Brent for October settlement lost $0.39, or 0.7%, to $58.18 on the ICE Futures Europe Exchange. The contract closed little changed on Monday after rising 4.1% in the past two sessions. The global benchmark crude traded at a $3.66 premium to WTI for the same month.
