U.S. corn futures fell more than 3 percent on Monday as forecasts called for much-needed rain in the Midwest. Soybeans also weakened, while wheat slipped under pressure from corn and soy and from the U.S. winter wheat harvest.
Corn posted the biggest declines because it is seen as the most likely to benefit from the rains.
Improved moisture before corn pollination lowers the odds of a drought-related yield cut, which weighs on near-term feed grain prices. Soybeans are less sensitive to July weather, so their move is smaller.
After 357 past bearish weather events, Corn moved a median -0.3% over 5 sessions (44% higher; middle half -2.2% to +1.3%), and -0.5% over 20.
After 363 past bearish weather events, Soybeans moved a median -0.6% over 5 sessions (42% higher; middle half -2.5% to +1.1%), and -0.2% over 20.
After 334 past bearish weather events, Wheat (SRW) moved a median -0.2% over 5 sessions (47% higher; middle half -1.9% to +1.7%), and -0.2% over 20.
