Potential for a Post-Harvest Corn Price Rally

Central Illinois corn prices climbed to the mid-$3.80 range last week with some locations offering above $4 for fall delivery. While December futures prices struggle to break through $4, the potential for a smaller crop holds the promise of a price rally despite weak demand. A strong rally depends on the ability of supply issues to overwhelm demand weakness, according to University of Illinois agricultural economist Todd Hubbs.  

“Corn demand in some key areas limped out of the gate this marketing year,” Hubbs says. “USDA’s consumption forecast sits at 14.015 billion bushels, down 459 million bushels from the previous marketing year. Corn used for ethanol production is forecast to increase by a mere 24 million bushels during this marketing year after a weak performance in the 2018-19 marketing year.”

An increase in corn use for ethanol production might be generated by a continued expansion in gasoline consumption or recovery of the ethanol export levels witnessed in the 2017-18 marketing year.

“Increased ethanol exports to China under the proposed agreement seems probable. Ethanol production sits down about 7% through Oct. 11. Corn used for ethanol production in September will be released in the USDA's Grain Crushings and Co-Products Production report on Nov. 1,” Hubbs notes.   

“It seems unlikely that corn used for ethanol production this year would fall from the current USDA projection by more than 75 million bushels,” he adds “Feed and residual use of corn are currently projected at 5.3 billion bushels this marketing year. Additional increases to feed use could occur based on current livestock prices and inventories. A smaller crop may reduce the residual use. At this point, a significant change in the USDA feed and residual use projection seems unlikely.”

At 1.9 billion bushels, U.S. corn exports are forecast at 165 million bushels lower than exports of a year earlier. The decrease reflects the slow start for exports thus far this marketing year.  Export inspections through the first seven weeks of the current marketing year were 193 million bushels lower than inspections of a year earlier. Accumulated exports come in equal to almost 5% of the USDA export projection compared to a five-year average of 11%. Outstanding sales as of Oct. 10 were approximately 44% smaller than outstanding sales of a year earlier. 

“Caution remains necessary when measuring the export potential for the current year based on the level of export sales relative to the prior year. U.S. exports may begin slowly and build throughout the marketing year due to the South American production shortfalls or other consumption factors,” Hubbs says.

Current projections of corn production in Brazil and Argentina sit slightly lower than last year’s massive crop. Early planting issues due to dryness in large areas of both nations may lead to a more moderate outcome. While corn use projections sit lower, the potential for substantially lower consumption this marketing year remains dependent on the export market.

Despite the weak demand, the ending-stock projection of 1.929 billion bushels comes in 185 million bushels lower than last year on reduced supply. The forecast of the 2019 corn crop sits at 13.779 billion bushels, down 641 million bushels from last year. The impact of the winter storm that struck the western Corn Belt last weekend remains uncertain. Estimates of crop loss range from 150 to 450 million bushels.

“All of these estimates are pure conjecture at this point,” Hubbs says. “The release of the USDA's Crop Production report on Nov. 8 provides an updated forecast and includes a re-survey of potential harvested acres for North Dakota and Minnesota. An expectation of a reduction in the 2019 production forecast exists, but the magnitude of the 2019 corn crop may not truly be revealed until January. The potential for a continuation of the corn price rally after harvest depends on whether a reduction in supply can overwhelm weak demand.”

USDA projects the seasonal average price for corn at $3.80. At the close on Friday of last week, futures market prices combined with historical basis levels throughout the marketing year set the price at $3.86. Cash prices increased around 40 cents since early September in central Illinois, but still sit well below the highs seen in mid-July.

Hubbs explains that if the projection for corn consumption and ending stocks currently in place from USDA holds, any price appreciation over the next few months would result from a strengthening basis. Over the last two marketing years, the central Illinois corn basis appreciated around 16 cents from mid-October to the end of February. For cash corn prices to move higher than the low $4 range, the 2019 corn crop needs to decrease by a total close to the high end of the range predicted from the winter storm crop loss. Production losses independent of the winter storm event also hold the potential for a strong rally.

“The prospect of support for corn prices due to a reduction in the estimated size of the 2019 U.S. crop appears likely, but weak demand looks to blunt the magnitude of a rally. Therefore, a smaller-than-expected South American crop or a much smaller U.S. crop in 2019 remain as potential sources for substantially higher prices,” Hubbs concludes. “In the near term, the continuation of corn prices in the current range is likely with the potential for a breakout associated with a realization of sharply lower crop production totals.”
