The USDA Foreign Agricultural Service in Pretoria forecasts South Africa's corn production will fall in marketing year 2026/27 from the record harvest, as farmers plant less corn and yields return to average. Some farmers are shifting to sunflower because of the El Niño threat and record fuel prices, and lower output will reduce exports.
Smaller South African corn output and lower exports reduce regional supply in southern Africa, modestly supporting corn prices, though record carry-over stocks limit the effect.
After 1,040 past bullish report events, Corn moved a median +0.5% over 5 sessions (62% higher; middle half -0.9% to +2.0%), and +0.8% over 20.
