On September 12th, SEC Chairman Mary Jo White met with leaders of the equities and options exchanges, the Financial Industry Regulatory Authority, the Depository Trust & Clearing Corporation, and the Options Clearing Corporation to discuss the August 22, 2013 interruption in the trading of NASDAQ-listed securities. The parties, in consultation with other market participants, will provide action plans that address the standards necessary to establish highly resilient and robust systems for the securities information processors ("SIPs"), including testing standards and disclosure protocols; identify and provide assessments of the robustness and resilience of other critical infrastructure systems; provide SIP plan and/or rule amendments addressing the issuance, effectiveness, and communication of regulatory halts; review their rules relating to the trade break process and procedures to reopen trading following a trading halt, and provide amendments to those rules as necessary; provide rule amendments to implement "kill switches" that would allow exchanges to shut down trading in the event of technological failures; and review and consider other potential risk mitigation mechanisms. SEC Press ReleaseSee also Washington Post (discussing the circa 1975 SIP system).
