MiFID II 2014/65/EU shall replace MiFID 2004/39/EG in Markets for Financial Instruments on 3 January, 2018. MiFID aims to harmonise financial markets in the internal European market.
The aim of the MiFID II directive is both further strengthening of investor protection and the restructuring of the securities and derivatives markets. This includes the regulating of trade infrastructures via commodity markets or the high frequency trade right up to protection of investors. With the enactment of MiFID II, the regulatory authorities gain expanded powers of intervention and sanctioning.
