On December 18th, the SEC approved a package of rule amendments, guidance, and a related order to expand and improve the framework for the regulation of cross-border security-based swaps, including single-name credit default swaps. This package also supports the SEC’s broad security-based swap regulatory regime in that it triggers the compliance date for security-based swap entities to register with the SEC and the implementation period for the previously adopted rules under Title VII of the Dodd-Frank Wall Street Reform and Consumer Protection Act. The rules create a coherent approach to the regulation of margin, capital, segregation, recordkeeping, reporting, and business conduct for security-based swaps.
