CME Launches Over-the-Counter Clearing Initiative for Interest Rate Products

Wed Mar 15 2006

CHICAGO, March 15 /PRNewswire-FirstCall/ -- CME, the world's largest and most diverse financial exchange, announced today that, pending CFTC approval, it will launch CME® Clearing360™, a new initiative that will provide a comprehensive clearing solution to over-the-counter (OTC) market participants. Expected to launch on April 3, 2006, CME Clearing360 will be an extension of existing CME Clearing services, and will offer customers the flexibility of OTC transactions with the risk management efficiencies of centralized clearing.

Initially, CME Clearing360 will permit bilateral OTC interest rate transactions, to be converted into futures contracts, beginning with "substitutions" using CME Eurodollar futures. Substitutions, or "subs," allow customers to substitute CME futures contracts for an OTC transaction in standard contract terms, such as an interest rate swap or forward rate agreement (FRA), with flexible settlement dates.

"The efficiencies offered by CME Clearing are a natural fit for the OTC market, and another example of CME expanding its reach into new markets," said CME Chairman Terry Duffy. "With this service, OTC market participants can take advantage of existing systems and infrastructure offered by CME Clearing and clearing member firms, along with the existing benefits offered by exchange- traded products."

"The OTC market can be extremely flexible since its products do not have to conform to a specific exchange product's size or value, but OTC market participants are also exposed to counterparty risk," said CME Chief Executive Officer Craig Donohue. "With CME Clearing360, we will offer the full resources of CME Clearing, the world's largest derivatives clearing organization, to a market that lacks the benefits of a central clearing process. Moreover, CME Clearing offers participants an added risk management advantage through our financial safeguards: customer collateral is segregated and protected from bankruptcy petitions of other market participants."

  CME Clearing360 will provide OTC participants the following benefits:

  -- Central counterparty clearing, which offers greater capital and
     operational efficiencies, including risk offsets against related
     futures and options positions;
  -- A proven history of risk management for the credit, operational and
     legal risks that customers face in OTC trading; and,
  -- Additionally, because CME Clearing is the counterparty to every trade,
     the risk of default is virtually eliminated.

CME Clearing is the world's largest clearing facility and processes more than 90 percent of all futures and options on futures contracts traded in the United States. As the counterparty to every trade, CME clearing settles accounts, clears trades, collects and maintains performance bonds, regulates delivery, and reports data. On a daily basis, it holds approximately $45.8 billion of collateral deposits to support the transactions that are being made in both CME Chicago Board of Trade (CBOT) markets.
