The author argues that for those wanting short crude oil exposure, USO is the most practical vehicle because of its high liquidity, while a micro crude future would be preferable if the trader had sufficient capital. The mechanism is liquidity-driven: USO's deep market makes it the easiest way to express a bearish oil view without futures access. No specific catalyst or time horizon is given, and the main risk is that USO's structure and roll costs can diverge from spot oil.
