Nigerian commodity exchange data showed sorghum and maize gaining over the week of October 18, 2022, with sorghum up 3.24% and maize up 3.03% in the open market. Flooding in key producing states was cited as a driver, while soybeans fell 2.47%.
Flood damage in producing regions and domestic demand support local grain prices, but the effect on global feed supply is small.
