The IMF's Consultative Group on Exchange Rate Issues (CGER) was formed in the mid-1990s to provide exchange rate assessments for a number of advanced economies from a multilateral perspective. The rapid increase in international trade and financial integration since then has inspired the IMF to place stronger emphasis on multilateral surveillance, macro-financial linkages, and the implications of globalization. The CGER therefore has broadened its mandate to cover both key advanced economies and major emerging market economies, and this Occasional Paper summarizes the methodologies that underpin the expanded analysis.
