The increasing occurrence of national, regional, and global financial crises, together with their rising costs and complexity, have increased calls for greater regional and global monetary cooperation. This is particularly necessary in light of volatile capital flow movements that can quickly transmit crisis developments in individual countries to other countries around the world. Global financial safety nets (GFSNs) are one important area for monetary cooperation. This paper reviews the current situation of regional and global monetary cooperation, focusing on financial safety nets, with a view toward developing recommendations for more effective cooperation, especially between the International Monetary Fund (IMF) and regional financial arrangements (RFAs).
