WTI crude prices are down $1.21 to $91.06 early in the week after Chinese industrial production grew at the slowest year-over-year pace since 2008, excluding Lunar New Year holiday skews.
The 6.9% rise in factory production fell well short of the 8.8% consensus estimate and 9.0% pace in July.
Another factor weighing on crude prices is Libya where production continues to increase and hit 870K barrels per day, according to the state-run oil company.
Crude prices have been in a slide since June and on Thursday hit $90.43, which was the lowest since May 2013.
