Summary
- The present year experienced unique challenges and exceptional volatility, as drought has ravaged the American upper-Midwest corn-growing regions in early summer 2023.
- The U.S. National Oceanic and Atmospheric Administration has revised its forecast to include likely hotter-than-average conditions in the upper-Midwest.
- No matter what the future holds for corn, the summer months bear close watch as the weather will impact prices, and global supply can change according to the level of rainfall.

At A Glance
- Drought conditions in the early summer have resulted in some of the lowest corn quality ratings in years across the Corn Belt.
- Volatility in Corn futures in June at times surpassed June 2022 levels on fears of low yields.
Cornstalks sway in the breeze and (corn-fed) 'dogs are on the grill: American agriculture is always front of mind in the summertime. Weather, planting, harvest, and stocks all impact field crops in the United States throughout the summer months, making the season the most volatile of the year for U.S. corn. The present year, however, brings unique challenges and exceptional volatility, as drought has ravaged the American upper-Midwest corn-growing regions in early summer 2023.
Lowest Quality Ratings in Years
According to the late June USDA Crop Progress report, only 26% of corn in Illinois was rated as good or excellent for the week ending June 25, 2023; the lowest percentage of Illinois corn to see such a rating at this time of year since 1988. In Indiana and Iowa, the percentage of corn rated as good or excellent hovers near levels last seen in 2019, a year of "biblical" levels of spring rain.

Summertime Volatility and Seasonality
Field crops such as corn demonstrate seasonality or regular patterns of supply and demand over the course of the calendar year. In the United States, corn is planted in the spring and harvested in the fall, with the specific time of planting and harvest dependent on the particular conditions of the year.
CME Group Corn futures are listed for expiration in March, May, July, September, and December. Midwestern Corn that is harvested in the fall, after drying in the field, is deliverable by November or December and serves as the underlying physical commodity for December Corn futures. As such, December[1] Corn futures are referred to as a "new crop" instrument because the grains deliverable against the futures have been newly harvested. May Corn futures, conversely, are an "old crop" expiry, because the grain deliverable against May Corn futures has been in storage since its harvest the prior autumn. Relative Corn futures prices tend to peak in the summer, as the old crop ages and supply tightens.

New crop instruments experience distinct market dynamics from old crop instruments. Extreme summer weather, for example, may impact new crop instruments more dramatically than it does old crops, since it may affect yields.
That is one reason why more Corn market participants are looking to short-dated new crop options contracts to hedge against sudden price swings due to changing weather. The latest tool available in 2023 is weekly options on new crop corn , which expire each Friday from February through August.
The Year Ahead
The U.S. National Oceanic and Atmospheric Administration (NOAA) is predicting a long, hot summer in much of the United States due in part to the departure of La Niña, a cooling force, and an anticipated El Niño , a warming influence. Although NOAA previously predicted temperatures in the corn-growing powerhouse states of Indiana, Illinois, and Iowa to be normal relative to historic averages, the agency has revised its forecast to include likely hotter-than-average conditions in the upper Midwest.

No matter what the future holds for corn, the summer months bear close watch as the weather will impact prices, and global supply can change according to the level of rainfall.
