Thu May 18 2006

SEOUL, Korea and CHICAGO, May 18 /PRNewswire-FirstCall/ -- In cooperation with the Korean Ministry of Finance and Economy (MOFE), CME, the world's largest and most diverse financial exchange and the largest regulated marketplace for foreign exchange (FX) trading, today announced its plan to list futures and options on futures on the Korean Won. The contracts are scheduled to launch later this year and will trade exclusively on the CME Globex® electronic trading platform.

"We are extremely pleased to receive the support of the Korean Ministry of Finance and Economy for CME Won futures," said CME Chairman Terry Duffy. "The Republic of Korea represents one of the world's most important economies and CME Korean Won futures will provide global financial institutions, corporations and investors with a valuable tool to hedge fluctuations in the valuation of the Korean Won as they seek to manage the inherent risks in international currency markets."

"It is expected that listing of Korean Won futures contracts in CME will facilitate the Won's internationalization," said Tae-Kyun Kwon, Director- General of International Finance Bureau, MOFE. "We expect that boosted risk management on the Won through CME would encourage foreign investments in the Won-based financial products."

"The introduction of CME Korean Won futures and options contracts represents an important facet of our comprehensive and long-term Asian growth strategy," said Craig Donohue, CME Chief Executive Officer. "During the past two years, CME has launched a number of initiatives targeted to Asian-based investors, including our historic agreement with the China Foreign Exchange Trading System to provide Chinese banks with access to CME's foreign exchange and interest rate products, new products such as our CME E-mini® S&P Asia 50® and CME E-mini MSCI EAFE® futures contracts, the opening of our first Asian telecommunications hub in Singapore, the introduction of our Asia and Emerging Markets Incentive Plans, and the extension of the CME FX on Reuters service to Hong Kong."

CME received FX Week's 2005 eFX award for the best electronic futures platform. Last year, over 51 million FX contracts with a notional value of over $6.2 trillion traded at CME.
