Official Intervention in the Foreign Exchange Market: Elements of Best Practice

Abstract

This paper offers guidance on the operational aspects of official intervention in the foreign exchange market, particularly in developing countries with flexible exchange rate regimes. A brief survey of the literature and country experience is followed by an analysis of the objectives, timing, amount, degree of transparency, and choice of markets and counterparties in conducting intervention. The analysis highlights the difficulty of detecting exchange rate misalignments and disorderly markets, and argues in favor of parsimony in official intervention. Determining the timing and amount of intervention is a highly subjective exercise, and some degree of discretion is almost always necessary, though policy rules may serve as rules of thumb.
