Oil prices fell after a monthly survey by HSBC found that China's manufacturing, a driver of the global economy, contracted for a second straight month.
The HSBC purchasing managers' index also declined to the lowest since July, a sign of the extended slowdown in China as leaders in Beijing try to clamp down on an investment boom and refocus the economy on domestic consumption.

Uncertainty about protests in Venezuela, a major U.S. oil supplier, as well as export disruptions in Libya and South Sudan kept a floor under oil prices.
Prices were also steadied by a weekly report from the U.S. Energy Department released Thursday that revealed that oil stockpiles grew about half as fast as expected, according to analysts surveyed by Platts, the energy information arm of McGraw-Hill Cos.
