由于担心美中之间的贸易战将损害支撑能源需求的全球经济增长，石油本月下跌超过6％。然而，特朗普总统试图在退出监督伊朗伊斯兰共和国核计划的协议后削减伊朗的石油出口，因此损失受到限制。巴克莱银行（Barclays Plc）警告称，随着特朗普的政策生效，第四季度价格将面临“巨大的上行风险”。

伦敦PVM Oil Associates Ltd.的分析师塔马斯•瓦尔加（Tamas Varga）表示，“上周阿拉伯半岛左右地区的地缘政治风险上升”，袭击沙特油轮以及美国与伊朗之间的关系日益紧张。“任何一次冲突的升级都将对全球石油供应产生破坏性影响。”

纽约商品交易所9月份交割的WTI原油价格上涨85美分至每桶69.54美元，截至伦敦时间上午11:09，交易价格为69.42美元。该合约上周下跌2.5％至68.69美元。周一交易量总量比100天平均值低34％。

West Texas Intermediate futures added 1.1 percent following a retreat of 2.5 percent last week. Three oil fields in the North Sea are winding down output before industrial action starts later Monday, a labor union said.

Barclays Plc warned of “ significant upside risk” for prices in the fourth quarter as Trump’s policy takes effect.

“Geopolitical risk rose last week from left and right of the Arab Peninsula,” with the attack on Saudi tankers and growing tensions between the U.S. and Iran, said Tamas Varga, an analyst at PVM Oil Associates Ltd. in London. “An escalation of either of the conflicts would have a devastating impact on global oil supply.”

The dollar slipped 0.2 percent against the euro to $1.1685, boosting the appeal of assets such as commodities priced in the U.S. currency.
