CME Group Grain and Oilseed contracts are experiencing unprecedented volatility and price levels. In addition, tight stocks and uncertainty over 2008 crops in the United States make the March 31st USDA Prospective Planting Report a critical factor for prices in the near term.

In anticipation of this report, join Dr. Robert Wisner of Iowa State University and Mr. Joseph Victor of Allendale Inc. in a live online discussion on supply and demand fundamentals, insight on the expectations of the Prospective Plantings Report, and current and future impact of biofuels in the agricultural markets.

Since their migration to the CME Globex electronic trading platform in January, Corn futures have shown a deeper liquidity pool with larger market sizes throughout the day, tighter bid/ask spreads and lower implicit trading costs.

Using time-weighted average market liquidity statistics for the March 2008 Corn futures contract for the periods of 1/14/08 to 1/23/08, CME Group observed an 8 percent increase in top-of-the-book bid/ask size contracts during regular trading hours and up to a 54 percent increase in non-regular trading hours. In addition, implicit trading cost, represented by bid/ask spreads, decreased 49 percent during RTH and 32 percent in non-regular hours representing substantial cost savings to traders.
