MF Global Collapse Prompts Clash Over Collateral Rules for Swaps

CME Group Inc. sparred with the Vanguard Group Inc. and other derivatives buyers over whether U.S. regulators should extend collateral-protection rules designed for the swaps market to the futures industry following the collapse of MF Global Holdings Ltd.

Speaking yesterday at the opening of a two-day roundtable organized by the U.S. Commodity Futures Trading Commission, derivatives buyers including Tudor Investment Corp. and Fidelity Investments urged the commission to add the new collateral-segregation standards to the futures market.
