The European politicians responsible for rubber-stamping the revised Markets in Financial Instruments Directive have expressed last-minute concerns over the new trading rulebook– their final chance to influence the rules, which are set to come into force in 2017.

In written comments sent to the European Commission on October 19, five European Parliament members set out their concerns over the final regulatory technical standards underpinning Mifid II. The revised directive, which forms part of the EU's response to the financial crisis, is set to transform the trading landscape by increasing transparency across a range of asset classes.
