The Financial Services industry in Europe is facing radical new changes to the way its business is regulated. The recasting of the Markets in Financial Instruments Directive, known as MiFID II, represents the biggest shake-up of regulatory legislation in the European financial sector for over a decade. Far-reaching new rules aim to strengthen investor protection, prevent market abuse, increase transparency and re-establish consumer trust. However, meaningful engagement with the Directive has been slow. The scale, complexity and number of new regulations has resulted in a delayed response across the industry - and for firms based in the UK this has been compounded further by the result of the recent EU referendum. In this article we take an at-a-glance look at MiFID II and address some common misconceptions regarding the impact of the Brexit vote.
