Chicago Board of Trade wheat futures saw an increase on Friday due to concerns over adverse weather impacting production in Europe and China, and signs of weakening in the U.S. economy. The most active September soft red winter wheat contract settled up 7 cents at $5.39 per bushel. Other contracts, including September K.C. hard red winter wheat and September spring wheat, also saw increases. However, wheat futures faced some pressure due to forecasted rain relief in Argentina but found support with the possibility of storms halting the French wheat harvest.
