Hong Kong Bourse to Introduce Volatility Controls for Derivatives Market

Hong Kong Exchanges and Clearing ("HKEX"), the parent company of the Stock Exchange of Hong Kong ("SEHK"), said on Monday, 24 October, it plans to extend new volatility controls to its derivatives market on 14 November.

The volatility control mechanism, which has been operating successfully on the HKEX securities market since 22 August, aims to "protect market integrity by preventing extreme price volatility arising from major trading errors and other unusual incidents", the bourse said in a statement.

The new controls, which will apply to the Hang Seng Index ("HSI") Futures, Mini-HSI Futures, H-shares Index ("HHI") Futures and Mini-HHI Futures contracts, put contracts or stocks that trigger certain price thresholds into a five minute so-called "cooling off" period.
