The Corn Demand Curve
The accompanying scatter study shows the April/June monthly high for corn prices as a function of the ratio of US corn carryout stocks to crop year corn food and industrial plus exports. The data is from the USDA April World supply/usage report. The concept is to use the least elastic portion of the corn demand curve to forecast corn price. Futures prices are trading very near the curve derived in the 2000 through 2019 period.
In 2007 corn demand dropped off sharply in the second half of the crop year which resulted in a spring corn price well below what USDA expected in April. In 2013 demand remained strong into the summer keeping spring-summer corn prices strong to preserve a minimum pipeline carryout.
July corn may be able to hold above $3.25, but will probably need help from new crop, which is possible but unlikely, or a recovery in fuel demand to stage a significant rally.
