CME Launches CME Eurodollar Five-year E-mini Bundles

Thu Sep 07 2006

CHICAGO, Sept. 7 /PRNewswire-FirstCall/ -- To increase participation in its interest rate product complex, CME, the world's largest and most diverse financial exchange, today announced that it will launch CME Eurodollar Five- year E-mini® Bundles, a new contract that will have a notional value of $100,000, 1/10th the size of conventional CME Eurodollar Five-year Bundles. CME Eurodollar Five-year E-mini Bundles will begin trading exclusively on the CME Globex® electronic platform on Sunday, October 8, 2006, for a trade date of October 9.

The new E-mini Bundles' innovative design creates a more cost effective means of providing exposure for interest rate derivative market participants to the critical five-year point on the U.S. interest rate swap/CME Eurodollar futures curve. While a conventional five-year Eurodollar Bundle consists of 20 separate CME Eurodollar contracts, the E-mini Bundles provide exposure through a single contract. E-mini Bundles will have a simplified quoting convention based on price rather than the full size bundle's quoting structure of average net change from the previous day's close. The E-mini Bundles will be fully fungible, at a 10-to-one ratio, with the full size strip of 20 consecutive Eurodollar futures contracts, providing users of the new contract simultaneous access to the world's largest pool of short-term interest rate liquidity.

"CME Eurodollar Five-year E-mini Bundles will provide another means for market participants to trade the world's most liquid short-term interest rate derivatives product," said Robin Ross, Managing Director, CME Interest Rate Products. "We believe the new E-mini Bundles will open this market up to a wider range of participants, such as mutual fund portfolio managers, as the cost-effective, simplified design of this product will allow traders to hedge five-years of exposure with one single contract. The price quoting structure will make this contract easy-to-trade, chart and compare with related fixed income products."

Eurodollars are U.S. dollars on deposit in commercial banks located outside of the United States. Eurodollar deposits play a major role in the international capital market, and they have long served as a benchmark interest rate for corporate funding. CME Eurodollar futures are the world's most actively traded interest rate futures contract and serve as a benchmark for investors worldwide. Their liquidity provides traders and hedgers an opportunity to take advantage of their views on the direction of U.S. interest rates.
