An ETF Database article says a heat ridge forecast for July could threaten corn during pollination, after roughly half of US corn was planted in a two-week May window. A StoneX analyst said heat is the overwhelming market concern and prices rose sharply the prior Thursday.
Hot, dry forecasts during July corn reproduction raise yield risk and could lift corn prices if the ridge settles over the Midwest.
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.
After 1,079 past bullish weather events, SOY moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
