March crude oil prices traded lower throughout the early morning hours and fell to their lowest level since December 20th. Some traders pointed to yesterday's larger than expected EIA inventory build and new 11-year low in gasoline demand as forces weighing on the market. The week inventory reading seemed to overshadow yesterday's favorable economic data. EIA crude stocks rose 4.175 million barrels, which was about double market expectations. Current inventory levels are 4.217 million barrels below year ago levels but 10.405 million barrels above the five year average. Crude oil imports for the week stood at 8.88 million barrels per day compared to 8.853 million barrels the previous week. The refinery operating rate slipped 0.4% to 81.8%, compared to 84.5% last year and the five year average of 83.47%.
