Argentina's 2026-27 soybean estimate was raised eight percent from the prior forecast to 52.5 million tonnes, citing expected excellent yields under a developing super El Niño. Most added soybean area is expected to come at the expense of corn, particularly in the north, partly due to corn stunt disease.
A larger Argentine soybean crop and shift of acreage away from corn increase soymeal supply and ease soy prices, while reduced corn plantings support corn prices. The El Niño weather pattern is a key driver of expected yields.
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.
