USDA's July WASDE raised U.S. corn production for 2018-19 to 14.2 billion bushels and soybean production to 4.3 billion bushels. Winter wheat production was pegged at 1.193 billion bushels, and total wheat production rose to about 1.88 billion bushels.
A larger U.S. wheat crop adds supply pressure on wheat prices, while the corn and soybean changes mirror the broader report's bullish corn and bearish soybean effects.
