Oil futures clawed back some losses on Wednesday, recovering from 7-week lows as geopolitical tensions rose after Israel retaliated against an attack by Hezbollah, although prices remained under pressure from concerns about demand in China. Brent crude futures climbed 39 cents, or 0.5%, to $79.02 a barrel by 0020 GMT ahead of expiry on Wednesday, while the more active October contract was at $78.54, up 47 cents. U.S. West Texas Intermediate crude futures rose 52 cents, or 0.7%, to $75.25 a barrel.
