Securitization regulation remains, in the eyes of investors, banks, businesses, bureaucrats and politicians, one of the remaining unsolved puzzles of the post-Global Financial Crisis landscape. This book describes the key features of securitization, including the most common structures and their uses as well as the motivations of the participants in these markets. Important historical moments and case studies are frequently used to illustrate critical issues in the design and enforcement of regulation for securitized products. This work is intended to contextualize and contribute to the highly specialized debates between policymakers, regulators and the regulated financial intermediaries, setting out an agenda for discussion as well as providing some strongly held views on possible solutions. Written by an industry insider with over 20 years' experience in the markets, this book considers regulatory tools from all sides while avoiding common biases. It is a valuable source for not only regulators and policymakers, but also educators, students and researchers in financial regulation, financial engineering and investment management.
