Professor Niamh Moloney’s latest book has just been published, The Age of ESMA. Governing EU Financial Markets (Hart Publishing, 2018). Since its establishment in 2011, the European Securities and Markets Authority (ESMA) has become a pivotal actor in EU financial market regulation and supervision. Its burgeoning influence extends from the rule-making process to supervisory convergence/coordination to direct supervision. Reflecting the now critical importance of ESMA to how the EU regulates and supervises financial markets, and with ESMA at an inflection point in its evolution, particularly in light of the Commission's 2017 proposals to reform ESMA and the UK's withdrawal from the EU, The Age of ESMA maps, contextualises, and examines ESMA's role and the implications for EU financial market governance.
