In response to the global financial crisis, the Group of Twenty (G20) met in November 2008, for the first time at the leaders level, to agree on a comprehensive strategy to restore trust in the financial system and to limit the fallout from the crisis on global output and employment. Currently, there is a complicated governance structure for the program to reform the global architecture of financial regulation that consists of three entities — one ad hoc and self-selected (G20), one treaty-based and systemic (International Monetary Fund) and one a creation of the G20 (Financial Stability Board). This paper undertakes an analysis of how cooperation takes place among these actors to implement the fundamental reforms needed to ensure that the global financial system is better able to withstand shocks than it was in 2007-2008.
