Regardless of the ultimate winner in the U.S. market for rates futures, it is already clear the battle could dramatically pare traders' costs.
NYSE's co-owned clearinghouse, New York Portfolio Clearing, (NYPC) will use a cross-margining arrangement with its co-parent, the Depository Trust and Clearing Corp, to slash costs for traders who buy and sell in the cash and the futures markets at the same time.
CME, whose Chicago Board of Trade and Chicago Mercantile Exchange units have dominated interest-rate futures since they invented them decades ago, is maneuvering to keep its franchise. On Monday, it put forth a plan to offer cross-margining and save traders money.
Imitation is the highest form of flattery and we think we're onto something here, Walt Lukken, NYPC's chief executive officer, told reporters in a briefing.
CME said its margining plan would slash as much as 65 percent off the money that traders must put up to back simultaneously held positions in Treasury securities and futures. NYPC said savings would likely run in the 15 percent to 30 percent range and cautioned the CME's plans were too short on detail to adequately assess.
CBOT has successfully fended off several challenges to its interest-rate futures business over the years.
