CME Group corn futures and options trade both by open outcry and by electronic trading. During what are called "regular trading hours" (RTH), corn futures trade side-by-side on Globex and on the trading floor, while options trade only on the trading floor. During electronic trading hours (ETH), both corn futures and options are traded.
CME Group corn futures and options migrated from the eCBOT trading platform to CME Globex on the evening of Jan. 13, 2008.
On Aug. 10, 2011, it was announced that, starting Aug. 22 of 2011, corn would be allowed to rise or fall by 40 cents per bushel in daily trading, an increase over the previous 30-cent-limit and a response to a year of volatile, market limit trading days for corn. Permission was received from the Commodities Futures Trading Commission (CFTC) to increase the limits. The change would mark the first expansion in the daily trading limit for corn in 3-1/2 years. The exchange widened the limit to 30 cents, from 20 cents, in March 2008. CME's proposal to change the limits had run into stiff opposition from farmers, grain elevators and food companies, that said the increase was unnecessary. They complained the larger limit would increase volatility in the corn market and expose hedgers to bigger margin calls if prices would surge. CME tweaked the proposal in response to initial objections. It originally proposed to increase the daily limit to 50 cents.
Commitment of Traders
The CFTC regularly issues Commitments of Traders reports that show the distribution of open positions among different classes of traders. Information about corn positions is available in this report.
Corn's greatest use is feed for livestock and poultry. Corn is also used in many everyday food for humans, including corn oil for margarine, cornstarch for gravy and corn sweeteners for soft drinks. Additionally, corn is increasingly used in the production of ethanol. Other non-food uses of corn include in absorbing agents for disposable diapers and adhesives for paper products.
