The crude oil complex garnered a measure of support this morning from weakness in the US dollar, a rebound in global equity markets and continuing uncertainty in Libya. Many players continued to monitor the unrest in Libya, noting that the situation remained tenuous after Muammar Gaddafi said he would remain in power till the end. While Libya has cut off energy supplies to Italy, more nations are speaking up in favor of imposing sanctions against Libya as a way to invoke change. France was the latest to voice ideas of sanctions, and it is possible that there will be more input from the US later today. March crude oil expiration has come and gone and left a surge in volume to extremely above average levels in its wake. It is likely that March expiration, along with active spreading between Brent crude oil exacerbated Tuesday's rally.
