Derivatives, or financial instruments whose value is based on an underlying asset, played a key role in the financial crisis of 2008-2009. Congress directly addressed the governance of the derivatives markets through the Dodd-Frank Wall Street Reform and Consumer Protection Act. This Act, in Title VII, sought to bring the largely unregulated over-the-counter (OTC) derivatives markets under greater regulatory control and scrutiny. Pillars of this approach included mandating that certain OTC derivatives be subject to central clearing, such as through a clearinghouse, which involves posting margin to cover potential losses; greater transparency through trading on exchanges or exchange-like facilities; and reporting trades to a repository, among other reforms. This book examines the G-20 recommendations for reforming OTC derivatives markets and presents the result of self-assessment surveys measuring the performance of G-20 members and some FSB members to date in meeting their commitments. It also discusses the key issues in derivatives reform; describes some of the requirements placed on the derivatives market by the Dodd-Frank Act; analyzes why countries coordinate economic policies and the historical origins of the G-20; how the G-20 operates; major highlights from previous G-20 summits, plus an overview of the agenda for the next G-20 summit; and debates about the effectiveness of the G-20 as a forum for economic cooperation and coordination.
