Oil prices rose on Monday as global supply is tightening with lower exports from Saudi Arabia and Russia, offsetting nagging concerns about global demand growth amid high interest rates.
Brent crude climbed 61 cents to $85.41 a barrel by 0649 GMT, while U.S. West Texas Intermediate crude was at $81.88 a barrel, up 63 cents. The September WTI contract expires on Tuesday and the more active October contract gained 56 cents to $81.22 a barrel.
