CME, the world's largest and most diverse futures exchange, posted total 2005 annual volume of 1.05 billion contracts as it achieved double-digit volume gains for the sixth consecutive year. CME total average daily volume in 2005 was nearly 4.2 million contracts, up 34 percent from 2004.

CME set annual volume records in all four product groups. Average daily volume in CME's interest rate products of 2.4 million contracts for the year climbed 40 percent from the all-time record volume levels achieved in 2004. This increase was driven by continued growth in CME Eurodollar options, up 45 percent to 746,000 contracts per day in 2005 from the same period a year ago, and electronic CME Eurodollar options, up 234 percent from 2004. CME Eurodollar futures grew 38 percent to 1.6 million contracts per day. Electronic CME Eurodollar futures averaged 1.3 million contracts per day in 2005, up 125 percent from the same period a year ago. CME Eurodollar futures remain the most actively traded futures contract in the world.

CME's foreign exchange complex saw year-on-year average daily volume increase 65 percent to more than 334,000 contracts per day in 2005. Combined average daily volume in CME's E-mini equity product complex was approximately 1.3 million contracts in 2005, up 21 percent compared with 2004. CME's equity standard volume grew 13 percent to 131,000 contracts per day. CME's commodities product complex experienced its third consecutive year of double- digit growth, and was up 23 percent compared to 2004.

In spite of the normal year-end slowdown, overall fourth quarter trading activity remained strong, with average daily volume above 4.1 million contracts, up 33 percent from the same period in 2004. Leading the growth was a 49 percent increase in foreign exchange (FX) trading, averaging a record 375,000 contracts per day. CME continues to see very strong participation in its FX business from high velocity algorithmic traders. In addition, CME interest rate volume had a 34 percent increase, averaging 2.2 million contracts per day. CME E-mini products averaged 1.3 million contracts per day, up 30 percent. And finally, CME commodity products increased by 20 percent with average daily volume of 51,000 contracts.
