The financial crisis led to a raft of new or updated EU conduct rules to ensure the orderly functioning of markets and market operators. The core measure is known as MiFID II, which is a radical update of the 2004 Markets in Financial Instruments Directive. MiFID II is now in the implementation phase and may bring further structural change to Europe's securities markets. Other measures have also been issued or updated, such as the rules against market manipulation and on short selling, and the formation and use of benchmarks. This ECMI Policy Brief reviews these new measures and discusses their effects.
