SUGAR
March raw sugar rose 0.15 cents, or 1.0 percent, to 14.78 cents per lb by 1425 GMT, after earlier hitting 14.82 cents, the highest for the spot contract since Aug. 3.
Dealers noted speculators had been reducing a large net short position in raw sugar.
Brazil mills have also increased the amount of cane used for ethanol production this month and reduced sugar output.
"Relatively stronger ethanol prices will help absorb a portion of the sugar surplus that the market is forecasting for the next season," ING said in a market note.
Global supplies, however, remained ample ahead of the Thai harvest, with the country potentially poised for stronger sugarcane output in 2017/18 than previously expected.
"Higher sugarcane prices in the last season are likely to have increased the area under sugarcane cultivation," Tropical Research Services said in a market update, noting above-average rains had also been beneficial to yields.
December white sugar was up $3.40, or 0.9 percent, at $384.30 a tonne.
