Mar crude oil ($91.62 +3.51) continued yesterday's rally overnight and has extended higher at mid-session, breaking back above the $90 level.

Crude may also have downside protection as several OPEC ministers said this morning that the cartel may cut output at its next meeting on Mar 5, if necessary, to keep crude above $80
