An analyst commentary on June 21, 2021, argued that volatility in summer grain markets will persist because balance sheets have little buffer against production shortfalls. It said current corn values are justified and that December corn could fall below $5.00 if acreage rises and the weather moderates, while depleted western subsoil leaves crops vulnerable to dryness.
Dry subsoil in the western Corn Belt and the weather premium support corn prices through pollination, while expected acreage gains and better weather could erode that premium before harvest.
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.
