Cocoa and raw sugar futures saw a sharp decline on Monday due to the liquidation of long positions by funds and heavy short selling. London cocoa prices fell by 3% to 6,170 pounds per metric ton, with a 18% loss in the last quarter. New York cocoa contracts also dropped by over 20% in the last two weeks. October raw sugar fell by 0.3% to 20.23 cents per pound, but the market remains uncertain with delivery figures and upcoming rainfall in Brazil. Robusta coffee prices rose by 1.4% to $4,067 a tonne, while Arabica coffee prices fell by 0.9% to $2.2485 per pound, influenced by the weak Brazilian currency.
