Bullish: Crude will move up due to quantitative easing (QE 2), which will depress the U.S. dollar and thereby increase the cost of commodities like oil.
Bearish: Inventory is comfortable, supply is ample relative to weak demand due to a weak economy. Interesting though, is that one of the bearish cases for oil (shift away from heating oil to more natural gas), is a bullish pull for natural gas, as more natural gas is expected to replace petroleum based energy.
Here is a link to an article that expands on the bull and bear case for crude oil.
