IOSCO consults on recommendations to help trading venues manage extreme volatility

07 March 2018

IOSCO explores the measures that trading venues use to address the risks posed by extreme volatility. The report finds that these mechanisms can be an effective way for trading venues to mitigate the effects of extreme volatility and preserve orderly trading.

The Board of the International Organization of Securities Commissions is seeking feedback on its proposed recommendations to assist trading venues and regulatory authorities in the implementation of mechanisms to manage extreme volatility.

In the report, IOSCO proposes eight recommendations to assist trading venues and regulatory authorities when considering the implementation, operation, and monitoring of volatility control mechanisms. Specifically, the report recommends that:

• trading venues should have mechanisms to manage extreme volatility and these mechanisms should be appropriately calibrated and monitored;

• regulatory authorities should consider what information they require to effectively monitor the overall volatility control mechanism framework in their jurisdiction, and ensure that trading venues maintain relevant records;

• information about volatility control mechanisms and when they are triggered should be made available to regulatory authorities, market participants and, if appropriate, the public; and

• communication amongst trading venues should be considered where the same or related securities are traded on multiple trading venues in a particular jurisdiction. In addition, where the same or related instruments are traded in different jurisdictions and the mechanism is triggered, communication may be appropriate.

The report also highlights the issues that arise where this information sharing and communication between trading venues occurs across jurisdictions.

Public comments on this consultation paper should be submitted on or before 6 May 2018.
