SUGAR

July raw sugar was up 0.06 cents, or 0.5 percent, at 12.41 cents per lb by 1413 GMT.

Dealers said the market's recent rally from a 2-1/2 year low for the front month of 10.69 cents on April 25 has prompted trend-following investors to take a bullish stance.

"We think momentum investors are continuing to buy back their short positions," Commonwealth Bank of Australia analyst Tobin Gorey said in a market note.

Dealers noted speculators had reduced a net short position of more than 170,000 lots on April 24 to only 42,291 lots as of June 5.

A slight weakening in Brazil's real currency on Tuesday, however, helped to pare gains.

Many Brazilian coffee and sugar producers saw a rare opportunity last week to fix prices with solid profit margins at a moment of global oversupply for both products, moving quickly to cash in when the local currency hit its cheapest levels in two years.

Dealers noted both the cane crush and sugar production in centre-south Brazil fell in the second half of May, partly because of a nationwide truckers' strike.

The region produced 1.34 million tonnes of sugar in the second half of May, compared with 1.907 million tonnes in the previous two-week period, cane industry group Unica said on Tuesday.

An S&P Global Platts survey of analysts had seen sugar production at 1.43 million tonnes.

August white sugar rose $2.50, or 0.7 percent, to $353.50 a tonne.

COCOA

September New York cocoa rose $27, or 1.1 percent, to $2,435 a tonne as the market regained some ground after last week's fall to a three-month low of $2,320.

Dealers said the market was underpinned by concerns about dry weather in top grower Ivory Coast while the long liquidation by speculators that had kept the market under pressure recently appeared to have petered out for now.

September London cocoa was up 13 pounds, or 0.75 percent, at 1,748 pounds a tonne.

COFFEE

September arabica coffee was up 0.25 cents, or 0.2 percent, at $1.1945 per lb.

September robusta coffee fell by $6, or 0.35 percent, to $1,717 a tonne.
