Oil jumps more than 2 percent as Wall Street up, dollar down

Oil prices rose on Friday as the stock market strengthened and the U.S. dollar weakened, but U.S. crude futures remained on track to close the week down as investors remained worried about the global oil glut.

The week's trading was defined by bearish data about Chinese oil demand and rising crude production in the United States.

WTI crude CLc1 futures for September delivery rose $1.18 to $48.27 a barrel, a 2.5 percent gain. Brent crude LCOc1 futures for October delivery rose $1.40 to $52.43 a barrel, a 2.7 percent gain. Brent prices traded at a high point for the day of $52.57 and a low of $50.78 a barrel. About 218,987 lots of the front-month contract were traded by 16:15 GMT, some 65.5 percent of the previous session's volume.

"It's following the equity markets, and impacted by the dollar," said Tariq Zahir, founding member at Tyche Capital Advisors. Fundamentals for oil remain bearish as U.S. driving season nears an end, he cautioned.

Both benchmarks are on track to close the week lower, after bearish data early on.

"The main question is whether we will continue to see the kind of inventory draws that may show the supply-demand balance is tightening over the next few weeks," said Gene McGillian, director of market research at Tradition Energy.

Nigeria's crude oil exports are expected to slip to 1.72 million barrels per day (bpd) in October, loading programmes showed on Friday.

Signs of supply tightness have started appearing in the United States, the world's biggest oil consumer.

Despite a 13 percent jump in production C-OUT-T-EIA since mid-2016 to 9.5 million bpd, the country's commercial crude inventories C-STK-T-EIA have fallen 13 percent from their March records to below 2016 levels.
