The IMF Working Papers series is designed to make IMF staff research available to a wide audience. Almost 300 Working Papers are released each year, covering a wide range of theoretical and analytical topics, including balance of payments, monetary and fiscal issues, global liquidity, and national and international economic developments.
This paper tests several explanations for financial dollarization (FD), with an emphasis on Latin America. The results provide evidence that FD is a rational response to inflation uncertainty. The paper builds on previous research by finding that an exchange rate policy biased towards currency depreciation and currency mismatches tends to contribute to high FD and that FD is highly persistent. These results suggest that countries with significant FD should encourage the use of domestic currency by maintaining macroeconomic stability; allowing more exchange rate flexibility and less bias towards currency depreciation; and adapting prudential regulations to ensure that costs associated with FD are fully internalized in financial contracts. At the same time, restoring confidence in the domestic currency may take many years of sound policies.
