The European Securities and Markets Authority (ESMA) published a Discussion Paper setting out its initial views on the implementing measures it will have to develop for the new Market Abuse Regulation (MAR). The Discussion Paper presents positions and regulatory options on those issues where ESMA will have to develop MAR implementing measures, likely to include Regulatory Technical Standards, Delegated Acts and Guidelines. These implementing measures are of fundamental importance to the new regime, as they set out how MAR’s enlarged scope is to be implemented in practice by market participants, trading platforms, investors, issuers and persons related to financial markets. The deadline for comment is 27 January, 2014.
