Sugar prices on the New York and London stock exchanges saw a slight increase on Monday, but remain at their lowest since mid-September following significant drops last month. The market is now cautious ahead of a expected Unica report on Brazil's sugar production in the first half of December. The rise in prices was due to improved weather in Brazil, a weak real, a large harvest in India, and lower crude oil prices. On the New York Stock Exchange, prices for various contracts ranged from 17.63 to 19.54 cents/lbp, while on the London Stock Exchange, prices ranged from US$ 491.00 to US$ 512.20 per ton. In Brazil, the price of sugar varied in different regions.
