Barchart - Sugar prices posted modest gains on Tuesday, supported by surging crude oil prices. WTI crude (CLJ26) rose more than +4% on Tuesday to an 8.5-month high, which benefits ethanol prices and may prompt the world's sugar producers to divert more cane crushing toward ethanol production rather than sugar, thus reducing sugar supplies. Gains in sugar were limited due to Tuesday's rally in the dollar index ($DXY) to a 3.25-month high.
