South African agribusiness economist Wandile Sihlobo expects another good wet season in 2020/21 after a strong 2019/20 harvest, which was the country's second-largest grain crop on record. He notes that rainfall timing has become harder to forecast.
A good South African harvest would ease regional maize import demand and add modest supply pressure on white and yellow corn in southern Africa, with little effect on global 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.
