CBOT 2-Yr. Treasury Note Futures Open Interest Surpasses 600,000 Contracts

Date 15/05/2006

The Chicago Board of Trade (CBOT) announced today that on May 10, 2006, open interest in its Two-Year U.S. Treasury Note futures contract reached a new high for the tenth straight trading session, surpassing the 600,000 contract mark for the first time.  Open interest expanded to 607,802 contracts, compared with the prior day’s record of 588,177 contracts.

Yesterday’s open interest total in Two-Year Treasury Notes increased by more than 80 percent compared with the same date in the prior year.  During the first four months of 2006, average daily volume of CBOT Two-Year Treasury Note futures was 130,531 contracts, an increase of approximately 73 percent from the same period in 2005.

2 Year Options off to strong start

Because of the dynamic growth in the Two-year futures, the CBOT launched market maker programs, both on e-cbot® and in open auction, in the Two-year options contract late last year.  As a result average daily volume and open interest have grown quickly.  From January through May 10, 2006, average daily volume increased to 3,278 contracts from 313 contracts in December, 2005 and open interest grew to 65,162 contracts from 5,341 on December 31, 2005.
