SINGAPORE (Reuters) -Oil prices edged up on Monday, aided by hopes of rising fuel demand this summer despite being weighed down by a firmer dollar, as expectations of interest rate cuts were pushed out further following strong U.S. jobs data. Brent crude futures gained 28 cents, or 0.4%, to $79.90 a barrel by 0427 GMT and U.S. West Texas Intermediate crude futures was up 0.3%, or 26 cents, at $75.79 a barrel. On Friday, data showed the U.S. added more jobs than expected last month, leading investors to trim expectations for rate cuts, which helped the dollar to rally.
