COFFEE
* March robusta coffee was up $10, or 0.7 percent, at $1,518 a tonne by 1420 GMT, after climbing to a session high of $1,527.
* Dealers noted prices were edging higher in step with broader commodity and equity markets, although traded volumes remained thin.
* "We're just following the macro at the moment," one European dealer said.
* Gains were capped, however, by the threat of hedging by producers in top grower Vietnam, which is currently harvesting a massive crop.
* "Expectations are still for a surplus in both robusta and arabica," the dealer said.
* March arabica coffee fell 0.35 cent, or 0.3 percent, to $1.0140 cents per lb but remained above a three-month low of 98.60 cents set last week.
* The market attempted gains in earlier trade, boosted by a rally in the Brazilian real, but buying faltered as the currency softened.
* A stronger real discourages producer selling by reducing local returns on dollar-traded commodities like coffee and sugar.
* Fundamentally, the focus remained on ample supplies.
* "Central America needs to sell into the New York market," the dealer said. "(It's) probably going to run into some origin selling."

* March London cocoa rose 2 pounds, or 0.1 percent, to 1,755 pounds a tonne.
