Sugar prices gain, as Brazil tax move spurs talk of political favor.

Sugar prices extended their revival, returning above 14 cents a pound at one point, after Brazil unveiled a 20% tax on Brazil ethanol imports, in the latest of a series of moves by the top producing country of the sweetener deemed potentially positive for values. Raw sugar futures for October stood 2.1% higher at 13.95 cents pound in midday deals in New York, taking close to 8% the contract revival from a mid-month low. Earlier the contract touched 14.06 cents a pound.
