International Brent crude oil futures <LCOc1> were trading at $45.51 per barrel at 0623 GMT, down 18 cents from their previous close. U.S. West Texas Intermediate (WTI) crude <CLc1> was at $44.03, down 16 cents a barrel.

Both benchmarks were close to two-month lows reached last week.

Traders said that ongoing oversupply and growing economic headwinds were weighing on oil.

“Global oil demand in Q3 16 is growing at less than one-third the rate it was in Q3 15, weighed down by anaemic economic growth,” Barclays said on Monday.

“Demand support from the OECD has faded, while growth from China and India has slowed,” the British bank said.

Morgan Stanley said headwinds were growing for the second half of the year, leading to an expectation of lower oil prices. It pointed to resilient U.S. supply, falling demand for transport fuels, and oversupply by refiners, particularly in gasoline.

“As a result, crude oil demand from refineries is underperforming product demand by a wide margin,” the U.S. bank said, adding that growing economic risks added further to downside risks for oil.

A strong dollar and a fourth weekly rise in the U.S. oil rig count also weighed on prices, traders said. [USD/] [RIG/U]
