Crude oil prices were supported by the anticipation of a drop in Iranian oil imports this year as renewed U.S. sanctions take effect. Crude oil prices were also boosted by the increase in the crack spread to an 8-1/4 month high, which provides incentive for refiners to boost their crude purchases to refine the crude into gasoline. Crude oil prices were undercut by a stronger dollar.
