Oil prices fell for the third consecutive day over the collapse of financial derivatives broker MF Global Holdings, which increased concerns about the eurozone crisis.

US crude slipped 87¢ to stand at $92.32 a barrel at this morning, and ICE Brent crude oil fell by 76¢ to $108.80 a barrel.

MF Global filed for bankruptcy protection following bad bets on eurozone debt, according to Reuters.

The slowdown in factory activity in China also weighed on prices, which was the lowest PMI reading since February 2009, standing at 50.4 for October.
