October Brent crude on London’s ICE Futures exchange fell $1.03 to $49.02 a barrel.  In highly volatile trading Nymex crude and Brent crude gained 11.8% and 10.1%, respectively last week. In the same week, oil prices had slipped to multiyear lows, but clawed back gains to rise 16%-17% over the final two trading sessions.  On Monday, oil took cues from a softer start by Asian markets, with the Shanghai Composite Index down around 2% after Beijing placed a 16 trillion yuan ($2.506 trillion) cap on local government debt over the weekend, the latest move to address a slowing economy.
