Neogen's 2016 Capstone Report links wet weather, drought and heat to mycotoxin contamination in US and Canadian grain. Confirmed reports of DON in wheat, barley and corn and aflatoxin in corn are listed across multiple states.
Mycotoxin contamination raises feed safety risk and can limit usable supply of corn and barley, supporting prices for clean grain.
After 1,465 past bullish weather events, CORN moved a median +0.2% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.9% over 20.
Not enough comparable past events yet for a historical read.
After 1,072 past bullish weather events, WHEAT moved a median +0.2% over 5 sessions (55% higher; middle half -1.4% to +2.3%), and +0.3% over 20.
Moves of each commodity's benchmark from the last close before the event. Historical reads pool past events of the same kind; they describe what happened, not what will. Not investment advice.
