The financial crisis of 2007–2009 exposed the weaknesses of the global over-the-counter (OTC) derivatives market such as limited transparency regarding risk exposures, poor counterparty risk management practices, and the risk of contagion arising from interconnectedness in this market. In the aftermath of the financial crisis, regulators introduced worldwide legislative and regulatory changes aimed at increasing the transparency and stability of the financial markets. In this book, Dr. Olga Lewandowska explores those novel regulatory solutions and their impact. The main focus is on central counterparty (CCP) clearing that became mandatory for OTC derivatives under the new regulatory paradigm. In four research papers, she analyzes CCP from different risk perspectives and based on four diverse research methods. Her book offers a comprehensive assessment of the risk-reduction potential of the CCPs, their implications for the financial markets, and the practical challenges in the implementation of the recent financial market reforms.
