Sugar futures contracts have fallen due to concerns about a six-year high production in India, which has been reduced by heavy rains leading to less cane milling. This has led to a surge in sugar prices, with the recent increase also driven by Brazil's decision to end tax exemptions on ethanol imports, which may result in more sugar cultivars being used for ethanol production. The raw sugar contract for March delivery fell by 1.9% to 21.24 cents per pound, while the white sugar contract for the same month dropped by 2.7% to $551.30 per ton.
