The wheat market showed weak activity on three exchanges before Christmas, with futures prices falling. Wet weather is expected in the Plains next week. Algeria bought an unspecified amount of wheat in a tender, and corn futures closed higher. The European Commission has lowered its estimate for soft wheat production in the EU. The French wheat market also fell on Tuesday. The closing prices for January and March contracts on the Paris Stock Exchange (MATIF) were lower for milling wheat and corn, but higher for sunflower.
