SIFMA and the International Swaps and Derivatives Association (ISDA) provide comments to the Securities and Exchange Commission (SEC) on a proposed rule, which expands the antimanipulation provisions of Section 9 of the Exchange Act and authorizes the Commission to adopt rules to prevent fraud, manipulation, and deception in connection with security-based swaps (SBS), Proposed Rule 9j-1; Release No. 34-63236; File No. S7-32-10.  The associations share their concerns that the proposed rule would expand beyond the statutory approach, is overly broad and creates significant market uncertainty.
