CME Group to Launch OIS Futures and Options on Futures

Tue Jul 29 2008

CHICAGO, July 29 /PRNewswire-FirstCall/ -- In a further expansion of its short-term interest rate product offerings, CME Group, the world's largest and most diverse derivatives exchange, today announced plans to offer 3-month Overnight Index Swaps (OIS) futures and options on futures. The futures contract is scheduled to become available on Sunday, September 7, 2008, for a trade date of September 8, on the CME Globex® electronic trading platform and on Monday, September 8, 2008, for open outcry trading.

The new OIS futures contract will track the overnight effective Federal Funds rate, a major benchmark for the U.S. short-term interest rate market. The contract will reflect the Federal Funds rate compounded over a three-month period that ends on the contract's expiration date. Because the OIS futures contract will cover the same time period as a Eurodollar future, the contract will provide market participants with a direct and efficient way to trade the spread between 3-month LIBOR and 3-month overnight financing costs.

"In the current economic environment, an increasing number of short-term interest rate instruments are linked to the overnight Fed Funds rate," said Robin Ross, managing director, CME Group interest rate products. "Our new contract will be a welcome means of hedging OIS-linked risk exposure. Combining the new 3-month OIS contract with our benchmark Eurodollar futures will enable efficient trading of the Fed Funds/LIBOR spread, which has grown increasingly volatile, creating substantial risk for money market participants. The contract will also provide a direct way to take a view on FOMC policy moves further out the yield curve than is possible with our existing 30-day Fed Funds contracts."

The OIS futures will complement CME Group's rapidly growing 30-Day Federal Funds contracts, which reflect the average level of the overnight Federal Funds rate over a calendar month. CME Group's 30-Day Federal Funds futures and options have experienced strong growth over the past year. For the first six months of 2008, the contracts had average daily volume of 115,673 contracts a day, up 52 percent over the same period last year.
