Mon Dec 12 2005

CHICAGO, Dec. 12 /PRNewswire-FirstCall/ -- CME, the world's largest and most diverse financial exchange, today announced that it has appointed C.F. Wong to head its Asia office as Managing Director, Asia. Wong has over 25 years of experience in international futures markets, including roles as Chief Executive Officer and Managing Director of ABN-AMRO Asia Futures, NatWest Futures Asia and HSBC Futures Asia. Wong will report to Rick Redding, Managing Director, CME Products & Services.

CME currently operates offices in Tokyo and Sydney, as well as a telecommunications hub in Singapore that serves the Pan-Asian marketplace, and these operations will become part of a larger, more comprehensive effort to grow the company's outreach to customers in this region.

"Asia represents enormous long-term growth opportunities for CME as we successfully execute our global strategy, and C.F. and his team will build even more momentum for international business development," said CME CEO Craig Donohue. "According to the Bank for International Settlements, financial markets in China, India and the Asia-Pacific Region are growing at an extremely rapid rate. For example, between 1998 and 2004, exchange-traded derivatives grew at a compounded annual growth rate of 69 percent in Asia, compared to a 29 percent rate in North America. With our global benchmark products, around the clock trading on our CME Globex electronic trading platform and our talented Asian business team, we will continue to expand the reach of our products and services and provide additional value to our customers and shareholders."

"We continue to broaden distribution of our products and services to Asia, particularly through CME Globex, which is the most widely distributed derivatives electronic trading platform in the industry," said Redding. "We are excited to have C.F. become part of this team, as his experience, leadership and track record of innovation will help us to leverage even more opportunities to grow our business in the Asian marketplace."

Wong, 50, previously served as a Managing Director for Octagon Advisors, serving as an advisor to banks in Singapore and China. He worked as Executive Vice President for United Overseas Bank (UOB) Group's High Net Worth Banking arm, as Managing Director of UOB Bullion and Futures, and as Chief Executive Officer and Managing Director of ABN-AMRO Asia Futures, NatWest Futures Asia and HSBC Futures Asia. He began his career at The Monetary Authority of Singapore.

     Shenzhen Stock Exchange, Dalian Commodity Exchange and Zhengzhou
     Commodity Exchange, all in China.

  -- In October, CME announced plans to launch a new futures contract based
     on the S&P Asia 50 Index, the only Pan-Asian equity index that tracks
     the 50 largest stocks traded in Hong Kong, Korea, Singapore and Taiwan.
     This contract is expected to launch in the first quarter of 2006
     exclusively on the CME Globex electronic trading platform.

  -- In partnership with the Shanghai Futures Exchange and Shanghai Stock
     Exchange, CME hosted the China Financial Derivatives Forum in Shanghai
     in September 2005.

  -- Also in September, CME marked the 15th anniversary of its CME Nikkei®
     225 futures contract, the first contract based on a non-U.S. based
     stock index to trade on a U.S. derivatives exchange.  Since its launch
     on Sept. 25, 1990, over 9.1 million CME Nikkei 225 futures contracts,
     representing a notional value of $580 billion, have traded at CME.

  -- CME launched its first telecommunications hub in Asia in June 2005,
     becoming the first overseas derivatives exchange to open an Asian
     telecommunications hub in Singapore.  This hub has improved access and
     reduced connectivity costs for CME market users in the region. In 2004,
     CME launched six hubs in key European financial centers following the
     opening of the inaugural hub in London in January 2002.

     history, and Reuters Financial News.

  -- The exchange signed Memorandums of Understanding with the China Foreign
     Exchange Trading System & National Interbank Funding Center in June
     2004 and Shanghai Stock Exchange in March 2005 to create forums for
     information sharing between the organizations regarding the potential
     development of derivatives products in China.

  -- CME introduced a number of incentive programs targeting traders in
     Europe and Asia, including the European and Asian Incentive Programs,
     Electronic Corporate Membership and a new tiered fee structure that
     provides incentives to high-volume customers trading CME Eurodollar
     futures.

  -- In January 2004, CME became the first non-Australian exchange to be
     licensed under the new Chapter 7 of the Corporations Act, allowing it
     to begin providing direct access to CME Globex and products traded on
     CME Globex to Australian market participants.

  -- CME continues to offer around the clock trading of its and Singapore
     Exchange Ltd's (SGX) interest rate products through its mutual offset
     system agreement.  Originally introduced in 1984, the mutual offset
     system provides that positions in selected contracts initiated at CME
     can be transferred and closed out - or offset - at SGX, and vice versa.
     The mutual offset system significantly expanded the length of the
     trading day and continues to provide market users with greater choice
     and access to market liquidity - particular in CME Eurodollars, which
     are successfully traded at SGX.  Year to date for 2005, over
     383 million Eurodollar futures have traded at CME.
