CME Reports Average Daily Volume of 4.7 Million Contracts in January, Up 27 Percent from Year-Ago Period

Wed Feb 01 2006

CHICAGO, Feb. 1 /PRNewswire-FirstCall/ -- CME, the world's largest and most diverse financial exchange, today said average daily volume in January was 4.7 million contracts, up 27 percent from the same period a year ago. Total monthly volume was more than 94 million contracts. Average daily volume on the CME Globex electronic trading platform increased 30 percent from the same period a year ago to 3.3 million contracts per day, representing 71 percent of total exchange trading. Overall electronic options trading continued to gain momentum as average daily volumes increased to 75,000, up from 19,000 in January 2005.

CME total interest rate volume was 2.7 million contracts per day in January, up 34 percent from the same period a year ago. This increase was driven by continued growth in CME Eurodollar options, up 48 percent to 928,000 contracts per day in January. Electronic trading of CME Eurodollar options has quadrupled since January 2005 to 47,000 contracts per day. CME Eurodollar futures grew 28 percent to 1.8 million contracts per day. Electronic CME Eurodollar futures averaged 1.5 million contracts per day in January, up 43 percent.

Average daily volume of CME foreign exchange products was 384,000 contracts, a 33 percent increase compared with January 2004, making CME the largest FX marketplace outside the interbank market. January 2006 was a record non-roll month for these products. During the month, electronic foreign exchange products increased 47 percent from the same period a year ago to 334,000 contracts per day.

Trading in CME E-mini™ equity index products averaged 1.4 million contracts per day in January, an increase of 13 percent compared with the same period last year. CME E-mini options average daily volume in January increased 246 percent month over month, averaging more than 27,000 contracts per day.

CME total commodity volume reached a record 81,000 contracts per day in January, up 50 percent over the same period a year ago. Commodity volume traded on the CME Globex platform also posted a record month in January with an 83 percent increase, reflecting the company's strategy of growing its customer base and providing side-by-side access to its commodity markets. In addition, the changing perception of commodities as an asset class has attracted unprecedented flows of capital into these markets, as commodity returns have outperformed equities since 1998.

Open interest for all CME products at the end of January was 36 million contracts, with an additional 42 million Total Return Asset Contracts™ (TRAKRS). Additionally, the Chicago Board of Trade had approximately 12 million open positions at the CME Clearing House at the end of January. Open interest represents the number of contract positions that remain open at the end of a trading session.

All statistics in this news release exclude data on CME's non-traditional TRAKRS™ products, and CME Auction Markets™ products, unless otherwise noted.
