SOFTS-Robusta coffee slumps to four-month low, cocoa sinks

LONDON, Dec 15 (Reuters) - Robusta coffee futures fell to a four-month low on Monday with the harvest in top producer Vietnam now in full flow after delays caused by storms and floods.

COFFEE

Robusta coffee LRCc2 was down 1.1% at $3,954 a metric ton at 1430 GMT after hitting a four-month low of $3,915.

Sucden Financial said in a note there was a band of support between $3,900 and $3,950.

"A clear break below this zone would expose the market to a deeper retracement towards the summer lows," the broker said.

Prices fell as low as $3,166 in July before rebounding in August, buoyed by a decline in exchange stocks after the U.S. government imposed a 50% tariff on imports from Brazil. The tariff was sharply reduced last month.

Robusta coffee speculators cut a net long position by 4,806 lots to 12,571 lots in the week to December 9, according to ICE Futures Europe data.

Arabica coffee KCc2 lost 2.2% to $3.6130 per lb.

COCOA

New York cocoa CCc2 fell 4.4% to $6,001 a ton, extending the market's retreat from a five-week high of $6,475 set last week.

About 91,000 tons were delivered between December 8 and December 14 to Ivory Coast's ports, up from 75,000 tons in the same week of the previous season, exporters estimated.

Dealers noted the December contract CCZ5 was due to expire on Monday.

London cocoa LCCc1 lost 5.4% to 4,309 pounds per ton.

SUGAR

Raw sugar SBc1 ​fell 1.9% to 14.81 cents per lb.

Dealers said a rise in sugar production in India remained a bearish influence although it may not be viable to export the surplus as prices in the global market are much lower than those in India.

White sugar LSUc1 lost 2% to $421 a ton.
