Arabica-coffee futures rose to the highest price in a week on reduced supplies. Cocoa also jumped.

Coffee exports from producing countries will fall for a second year in 2010 amid “scarcity,” according to the International Coffee Organization. Shipments will be below last year’s estimated 95.5 million bags and 97.7 million in 2008, ICO Executive Director said yesterday in an interview, without specifying the amount or percentage drop. A bag of coffee weighs 60 kilograms (132 pounds).

Supplies of the mild, washed arabica beans traded on ICE Futures U.S. “remain tight so the market should remain at a higher trading range,” said a vice president at Price Group Inc., a broker in Chicago.
