Current corn market structure reflects tighter supplies

Agriculture.com Staff 11/27/2006 @ 12:47pm

As the rapid pace of construction of ethanol plants unfolded, it was generally believed that corn supplies would be adequate for the current marketing year.

Concerns about supply shortages centered on the 2007-2008 marketing year and beyond.

Thoughts of current abundance and potential future shortages if production did not expand rapidly resulted in a large carry in the corn futures market. On September 13, 2006, for example, July 2007 futures prices were about $.31 above the price of the December 2006 contract.

December 2007 futures were $.47 above December 2006; December 2008 futures were $.15 above December 2007; and December 2009 futures, at $3.10, were $.10 above December 2008.

At the close of trade on November 17, 2006, July 2007 futures were only $.2075 above December 2006 futures; December 2007 futures were $.155 below 2006; December 2008 futures were $.1775 below December 2007; and December 2009 futures, at $3.19, were $.03 below December 2008.

The spread from December 2006 futures to December 2009 futures went from $.72 on September 13 to $-.3625 on November 17, a decline of $1.0825. The change reflected sharply higher prices in nearby contracts and more modest increases in deferred contract.

The changing structure of the corn market reflects a much tighter supply and consumption balance for the current year than anticipated in mid-September. September 1, 2006, inventories of old crop U.S. corn totaled only 1.971 billion bushels, 41 million less than forecast in mid-September.

The 2006 harvest is now estimated at 10.745 billion bushels, 369 million below the September forecast. The supply of U.S. corn for the current marketing year is 410 million bushels less than that projected two months ago. In addition, foreign wheat production this year is now expected to be 350 million bushels less than projected in September.

While the Chinese corn crop is now expected to be nearly 200 million bushels larger than forecast in September, larger Chinese exports are not expected. Harvest delays, increasing domestic consumption, and escalating domestic prices have led to speculation that some Chinese export sales may be re-purchased.

Argentina also announced a suspension of export sales due a surprisingly high level of export sales already on the books. Export sales of U.S. corn continue at a rapid pace, led by sales to Japan. Unshipped sales of U.S. corn to Japan as of November 9 were reported at 164 million bushels, compared to only 85 million bushels on the same date last year.

Mexico, Taiwan, and South Korea have also bought more U.S. corn than at this time a year ago. Columbia has purchased a substantial amount, 49 million bushels, of U.S. corn. Purchases by corn importers have likely been accelerated as concerns about available supplies increase.

While concerns about tight supplies for the current year have increased, there appears to be a little less concern about next year. It is expected that the high wheat prices will result in a substantial increase in world wheat production in the year ahead resulting in rebound in wheat feeding at the expense of corn.
