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

Exchange rate surveillance has always been at the core of the IMF’s responsibilities. Throughout its existence, the Fund has strived to strengthen its framework for assessing exchange rates, adapting it to underlying macroeconomic and financial developments in member countries. As part of this mandate, since the mid-1990s the Consultative Group on Exchange Rate Issues (CGER) has provided exchange rate assessments for a number of advanced economies from a multilateral perspective, with the aim of informing the country-specific analysis of Article IV Staff Reports and fostering multilateral consistency.

Are the current account fluctuations in oil-exporting countries "excessive"? How should their real exchange rate respond to the evolution of external (and domestic) fundamentals? This paper proposes methodologies tailored to the specific features of oil-exporting countries that help address these questions. Price-based methodologies (based on the time series of real effective exchange rates) identify a strong link between the real exchange rate and the terms of trade, but have relatively limited explanatory power. On the other hand, an empirical model of the current account, which fits oil exporting countries' data well, and an intertemporal model that takes into account the stock of oil reserves provide useful benchmarks for oil exporters' external balances.

The IMF's internal analysis of exchange rate issues has been guided by, and limited by, the conceptual and empirical frameworks that have emerged from the collective research of the economics profession. The research has provided several general approaches that are useful for assessing whether countries exchange rates seem broadly appropriate. One involves the calculation of purchasing power-party (PPP) measure or international competitiveness indicators. A second, known as the macroeconomic balance framework, focuses on the extent to which prevailing exchange rates and policies are consistent with simultaneous internal and external equilibrium over the medium run. Some recent extensions of the macroeconomic balance approach and the manner in which it is applied by the IMF staff are described in this paper.

In its surveillance activities, the Fund is frequently confronted with the difficult problem of how to identify exchange rate behavior that is unrelated to underlying economic and financial conditions and, consequently, should be viewed with concern from a national or international standpoint. This paper considers the various issues related to this problem as it pertains to industrial countries, both those that have independently floating exchange rates and those that operate under other exchange arrangements.

The IMF's Consultative Group on Exchange Rate issues (CGER) has been conducting exchange rate assessments as part of the surveillance process since 1997. This paper evaluates CGER assessments from 1997 to 2006, by comparing these to subsequent movements in real effective exchange rates (REER). We find that CGER's estimated misalignments have predictive power over future REER movements, especially over longer horizons and after changes in fundamentals are accounted for. But while CGER misalignments frequently predict the direction of currency movements correctly, misalignments have tended to be persistent, resulting in systematic errors-overprediction for undervalued currencies and underprediction for overvalued currencies.
