Almost entirely recast and rewritten from the 2008 second edition (published as EC Securities Regulation), this book provides the first comprehensive, critical, and contextual account of the vast new rule-book which now applies to the EU financial market in the aftermath of the seismic reforms which have followed the Global Financial Crisis. Topics covered in-depth include the AIFMD, EMIR, the Short Selling Regulation, the new market abuse and transparency regimes, the rating agency regime, the UCITS IV-VI reforms, and MiFID II/MiFIR; the analysis is wide-reaching, extending to secondary legislation and relevant soft law. The book also examines the far-reaching institutional changes which have followed and considers in detail the role and impact of the European Securities and Markets Authority and the potential impact of the Single Supervisory Mechanism for euro area banks on the supervision of the EU financial market.
