Oil prices rose in early trading on Tuesday, boosted by supply concerns caused by production cuts from Saudi Arabia and Russia. Brent crude futures increased by 37 cents, or 0.4%, to $85.71 per barrel by 00:10 GMT. U.S. West Texas Intermediate (WTI) crude recorded $82.37 per barrel, up 43 cents or 0.5%. Both contracts closed down about 1% in the previous session as investors brace for weak demand from the world's two largest economies, China and the United States. CMC Markets analyst Tina Teng noted in a memo that "Saudi and Russian production cuts could continue to be a source of optimism in the oil markets."
