Sugar futures saw a significant decline on the New York and London stock exchanges on Monday morning, with raw sugar dropping 1% in the main contract on the New York Stock Exchange to 20.71 cents/lb, and a 1.43% decrease in London at $580.00 a ton. This adjustment follows concerns about the Indian harvest, with the market also facing pressure from a profit-taking movement and the devaluation of oil, which influences the decision between sugar and ethanol production in Brazil.
