CBOT soybeans fell about 5.5 cents to $8.66 1/2 after China excluded the oilseed from a list of U.S. imports exempted from tariffs. Corn and wheat also declined on favorable Midwest weather.
Traders positioned ahead of USDA's monthly supply report due Thursday.
Continued Chinese tariffs on U.S. soybeans limit export demand, and warm weather for late crops reduces frost risk, both pressuring soybean and feed grain prices.
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 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 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.
