CBOT® Sets All-Time Records For Average Daily Volume And Total Monthly Volume - Electronic Trading Of Financial Options Reaches Monthly Volume Record

Date 01/06/2006

The Chicago Board of Trade (CBOT), one of the world’s leading derivatives exchanges, today announced that average daily volume (ADV) reached a record 3,628,552 contracts in May, an increase of 18 percent compared with May 2005. Total volume for the month also set a CBOT record, as 79,828,143 contracts changed hands. The previous record, 70,495,317 contracts, was set in March 2006.

Last month, the Exchange saw an increase in electronic trading of Financial options contracts, which set monthly records for total volume (1,957,589 contracts) and ADV (88,981 contracts). A record 20 percent of Financial options contracts were traded electronically at the CBOT in May versus six percent in May 2005. The new volume highs within the Exchange’s Financial options complex contributed to additional e-cbot® volume records. With an ADV of 2,558,094 contracts traded on its electronic trading platform in May, the CBOT set a record for total electronic trading volume – a ten percent increase compared with the previous electronic ADV record, set in February 2006.

CBOT Metals Volume Increases; Market Share Follows Suit

The 100-percent electronically-traded CBOT Metals complex captured a significant portion of the market last month. The CBOT Gold complex had approximately 37 percent market share of listed Gold futures in North America, while the CBOT Silver complex had approximately 27 percent of listed Silver futures in North America. ADV for the Metals complex was 67,798 contracts, a 61 percent increase over April 2006 and 24 times greater than May 2005. ADV for Gold and Silver futures contracts increased by 25 times and 15 times, respectively, compared with the previous May. The new CBOT Full-sized Gold options on futures contract had an ADV of 2,200 last month, more than three times greater than April 2006.

In May, daily Metals complex volume topped the 100,000 contract mark for the first time. 102,237 contracts changed hands on May 17, setting a new CBOT Metals volume record. The CBOT Metals complex includes Full- (100 Oz.) and mini-sized (33 Oz.) Gold futures, Full- (5,000 Oz.) and mini-sized (1,000 Oz.) Silver futures and Full-sized Gold options on futures contracts.

Exchange’s Financial Complex Displays Growth at Both Ends of Yield Curve

The CBOT Financial complex grew in May, as ADV increased by 12 percent compared with May 2005. In fact, with a complex-wide ADV of 2,962,899, volume in CBOT Financial futures and options increased at both the short end and the long end of the yield curve. At the short end of the curve (30-Day Federal Funds futures and options, Two-Year U.S. Treasury Note futures and options), May ADV climbed to 305,902 contracts, an 80 percent increase over May 2005. And on the long end of the curve (30-Year U.S. Treasury Bond futures and options, 10-Year Treasury Note futures and options), ADV was 2,021,526 contracts, up 13 percent compared with last May.

CBOT Two-Year Treasury Note futures had a successful May, as ADV improved to a record 213,222 contracts – a 94 percent increase over May 2005. On May 30, 2006, Two-Year futures set a daily volume record with 661,406 contracts traded. The previous record of 441,339 contracts was set February 26, 2006.

Strong Volume Totals Across CBOT Ag Complex

With an ADV of 386,444 contracts during May, CBOT Ag futures were up 46 percent compared with last May, and 24 percent year-to-date over the same period in 2005. Improved volume in the Exchange’s Ag complex was driven, in part, by strong performance in Wheat and Corn futures, which experienced ADV growth by 108 percent and 65 percent, respectively.

The CBOT Equity Index complex saw ADV increase to 126,964 contracts last month, 18 percent greater than May 2005.
