CBOT SETS NEW DAILY RECORD FOR TOTAL EXCHANGE OPEN INTEREST
Binary options over 24,000 in Open Interest

CHICAGO, IL, February 13, 2007 – The Chicago Board of Trade (CBOT) today announced that total exchange open interest reached a new daily record yesterday. Total exchange open interest hit 17,413,021 contracts, surpassing the previous record, 17,403,089 contracts, set on November 20, 2006.

In addition to the Agricultural complex achieving open interest records in several of the contracts over the past several weeks, recently launched new products are also contributing to the overall growth.  CBOT’s Binary options on the Target Federal Funds Rate open interest exceeded 24,000 contracts on Monday. The new open interest record, 24,438 contracts, tops the previous daily open interest records that have been continuously set since February 7, 2007. Binary option contracts topped over 20,000 for the first time on this day with 20,798 contracts. The CBOT launched this product in July 2006.  The new Ethanol Swap contracts which were launched on December 4, 2006 have also shown steady growth with open interest surpassing 1,200 contracts. 

Open interest represents the number of trading positions that have not yet been offset and closed at the end of a trading day.
