The Securities and Exchange Commission (“Commission”) is proposing to amend certain portions of the Covered Clearing Agency Standards under the Securities Exchange Act of 1934 (“Exchange Act”) to strengthen the existing rules regarding margin with respect to intraday margin and the use of substantive inputs to a covered clearing agency’s risk-based margin system. The Commission is also proposing a new rule to establish requirements for the contents of a covered clearing agency’s recovery and wind-down plan.
