The current international monetary system is in need of reform. This article first provides an assessment of the existing system, highlighting both its strengths and weaknesses. It notes that the system has not facilitated the symmetric and timely adjustment in the real exchange rate necessary to accommodate the integration of China and other emerging-market economies into the global economy. This lack of adjustment contributed to the global financial crisis and recession and, because it is forestalling the required rotation of global demand, is hindering the global recovery. The article then discusses reform of the system that would see all systemically important countries and currency areas adopt market-based and convertible floating exchange rates supported by appropriate monetary, fiscal and financial sector policy frameworks. It also examines the roles of the G-20 countries and major international financial institutions in promoting and facilitating the system’s transition.
