Arabica and robusta coffee on ICE Futures US fell after strong rallies in recent days sent prices into overbought territory, while a stronger dollar weighed on raw sugar prices.

December London cocoa settled down by 80 pounds, or 3.5 percent, at 2,183 pounds a tonne, after falling as low as 2,180 pounds per tonne, its weakest since late May.

The equivalent New York contract lost $123, or 4.3 percent, to settle at $2,762 a tonne, having touched its lowest since early February at $2,747.

Ivory Coast’s cocoa marketing board has given exporters six days to furnish documentation for exports, including proof of a counterparty, or contracts will be canceled and resold, the Coffee and Cocoa Council (CCC) wrote in a memorandum.

One dealer said the news was hitting cocoa hard because it will force local exporters to hedge, weighing further on the already bearish price outlook.

The measure is aimed at stamping out speculation in the forward sales system of the nation that produces 40 percent of the world’s cocoa.

“You’ll probably see some cocoa that had been held back coming to the market,” said Jack Scoville, vice president with PRICE Futures Group in Chicago.

The sharp drops capped off cocoa’s third consecutive week of losses, as recent rains in West Africa have improved the outlook for next season’s crop.

In coffee, ICE November robusta fell $18, or 1 percent, to settle at $1,909 a tonne, ending seven consecutive sessions of gains. The contract earlier hit an 18-month peak of $1,932.

Robusta prices have surged in the past month due to poor crops in Brazil and Indonesia and the prospect of a drop in production in top producer Vietnam. “(Robusta) moved into overbought territory after the strong rally, so we’re seeing gains pared back a bit,” said Ole Hanson, head of commodity research at Saxo Bank.

December arabica coffee settled down 3.75 cents, or 2.4 percent, at $1.5115 per lb.

October raw sugar fell 0.23 cent, or 1.1 percent, at 19.99 cents a lb, weighed down by a stronger dollar, while October whites settled down by 20 cents, or less than 0.1 percent, at $541.20 a tonne.—Reuters
