ASIC Market Supervision Update issue 11

Previous issues

ASIC has received questions from the industry about the interpretation and application of the new competition market integrity rules and the introduction of competition.

This newsletter includes information on the introduction of ASX's PureMatch and some frequently asked questions on a range of issues raised by industry about pre-trade transparency exceptions, certification of automated order processing systems, and best execution.

This newsletter supplements our guidance in Regulatory Guide 223: Guidance on ASIC market integrity rules for competition in exchange markets (RG 223). This is the first in what may be a number of communications.

Workshop on best execution and other compliance matters

ASIC intends to hold a workshop for market participants on 22 July on best execution and other compliance matters associated with the new competition market integrity rules. Further details will be emailed to participants over coming days.

Introduction of ASX's PureMatch

ASX has announced plans to introduce PureMatch, a new pre-trade transparent order book that will provide for trading in a subset of ASX listed securities. Purematch will operate in parallel to TradeMatch, the existing ASX order book.

More about PureMatch

Further operational changes

ASIC's approach to the introduction of competition has been to implement a regulatory framework that reflects the minimum needed for the commencement of competition and that will minimise system changes for industry and maintain market integrity. This reflects industry feedback to our consultation on Australian equity market structure in November 2010.

Against this background, ASIC will assess further market operator and participant operational changes in 2011 on a holistic basis to minimise the impact on participant readiness for competition and to maintain fair, orderly and transparent markets during the next phase of change.
