December 2010 corn futures traded to a high of $5.235 on September 27 and closed at $5.05 on Sept. 29. On Oct. 4, the surprisingly large USDA Sept. 1 corn stocks estimate released on Sept. 30 sent that contract to a low of $4.56, said University of Illinois agricultural economist Darrel Good.
Similarly, the November 2010 soybean futures contract traded to $11.295 on Sept. 27, closed at $10.99 on Sept. 29, and declined to $10.44 on Oct. 4, he said.
“Price declines came to a halt with the release of USDA’s October Crop Production report on Oct. 8. That report contained a unexpectedly small forecast of the size of the U.S. corn and soybean crops,” he said.
The corn crop is now forecast at 12.664 billion bushels, 496 million smaller than the September forecast and 446 million smaller than the 2009 harvest. Although the estimate of harvested acreage was increased by 258,000 acres, the forecast yield was lowered by 6.7 bushels, to 155.8 bushels, he said.
