Crude oil prices fell on Tuesday as traders took profit following a 3-4 percent upward swing in the previous session as conflicting market signals continued to tear at prices. Traders also focused on the soon-to-expire front-month contract in the West Texas Intermediate (WTI), which serves as the U.S. benchmark. U.S. West Texas Intermediate (WTI) crude futures were trading at $46.11 per barrel at 2347 EDT, down 57 cents from their last settlement.
