The September WASDE report surprised the market and pushed corn down about 6 usd/mt, soybeans about 5 usd/mt and soymeal about 10 usd/mt. USDA projected a high US corn yield and production up 2%, expanding global corn stocks.
Peruvian fishmeal prices rose by as much as 50 usd/mt as the first-season quota remained largely unfulfilled.
A larger US corn crop and bigger global stocks weigh on corn, soy and meal prices, while tight Peruvian fishmeal supply and fishing bans support fishmeal prices for feed buyers.
