Chicago Board of Trade wheat futures slumped for a third straight day on Wednesday, following both corn and soybean futures, as worries about growing trade tensions between the US and China hung over markets. CBOT September soft red winter wheat ended the day down 20-1/4 cents at $4.71-3/4 per bushel. K.C. September hard red winter wheat ended down 20-3/4 cents at $4.74 a bushel.
MGEX September spring wheat fell 12 cents, closing at $5.25-1/2 a bushel. Traders said US wheat exports remained sluggish and prices were still not competitive with Russia, "but we're moving in that direction, to be more competitive."
