On May 10th, the SEC proposed a new package of rule amendments and interpretive guidance to better the framework for regulating cross-border security-based swaps transactions and market participants. Intended to improve regulation by pragmatically addressing implementation issues and efficiency concerns, the proposed rules will further harmonize the regulatory regime governing security-based swaps administered by the SEC with the regulatory regime administered by the Commodity Futures Trading Commission (CFTC). These rules primarily pertain to security-based swap dealers and major security-based swap participants (SBS Entities).
