Fox Business reports that coffee prices rose on Wednesday which was helped by a weak dollar as the Fed concludes its policy meeting. The article states that Arabica coffee for December delivery was up 1.4 percent at $1.3720 a pound on the ICE Futures U.S. exchange, which is reportedly on track to break a two-day losing streak.
