A firmer Brazilian currency discourages producer selling in the top grower by reducing local-currency returns on dollar-traded commodities such as coffee. Drier weather in Brazil also supported prices, a US trader said. "Light showers will favor the southwest at the beginning of the period, but the majority of the time frame will be dry," weather service Radiant Solutions said in a note.
Technical buying also boosted prices, said Jack Scoville, vice president of Price Futures Group. March robusta coffee settled up $26, or 1.7 percent, at $1,556 per tonne, earlier hitting $1,558, near a one-month high.
