The Rosario Grain Exchange says the risk of excessive rainfall in Argentina’s Pampas has moderated, although November and December precipitation is still expected to exceed normal levels. Updated projections are below earlier estimates because Atlantic conditions, polar air circulation and pressure systems are tempering El Niño’s influence; rainfall may nevertheless arrive when corn and soybean crops need water.
Moderated flooding risk reduces the chance of weather-related planting or crop damage, while timely moisture could support yields and weigh on corn and soybean prices.
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.
