December New York cocoa settled down $17, or 0.8%, at $2,174 per tonne after slumping to a March 25 low of $2,165.
This was the contract's 19th negative finish in 21 sessions, as good weather in top-growing region West Africa has boosted expectations of plentiful supplies.
"Ivory Coast is likely to see a record high 2.3 million tons of cocoa harvested in the 2018/19 season. The prospects for the next main crop from October are likewise very good," said Commerzbank in a note. The contract has been in technically oversold territory on the relative strength index for nearly two weeks, which could help support a recovery in the event of bullish news, dealers said.
December London cocoa settled down 19 pounds, or 1.1%, at 1,698 pounds per tonne, after hitting a three-month low of 1,696. December arabica settled up 0.45 cent, or 0.5%, at 95.25 cents per lb, after setting a contract low of 93.40 cents. For the second position,, this was a three-month low. The market has struggled to absorb Brazil's record-large crop from last year, and expectations of another big Brazilian crop this year despite it being an off-year in the crop's biennial cycle weigh on the market.
The weak Brazilian real has also pressured prices of late. The real firmed on Tuesday but was still within striking distance of the three-month low against the US dollar hit in the previous session. November robusta settled up $5, or 0.4%, at $1,324 per tonne. October raw sugar settled down 0.03 cent, or 0.3%, at 11.44 cents per lb. October white sugar settled down $1.30, or 0.4%, at $309.10 per tonne.
