Despite significant strides in financial development over the past decades, financial dollarization, as reflected in elevated shares of foreign currency deposits and credit in the banking system, remains common in developing economies. We study the impact of financial dollarization, differentiating across foreign currency deposits and credit on financial depth, access and efficiency for a large sample of emerging market and developing countries over the past two decades. Panel regressions estimated using system GMM show that deposit dollarization has a negative impact on financial deepening on average. This negative impact is dampened in cases with past periods of high inflation. There is also some evidence that dollarization hampers financial efficiency. The results suggest that policy efforts to reduce dollarization can spur faster and safer financial development.

Uruguay has experienced a remarkable recovery since the 2002 crisis, supported by sound policies and favorable external conditions. With the framework put in place in 2002, Uruguay abandoned an exchange rate peg in favor of a free float, adoped a monetary regime initially based on money targets, improved financial prudential norms and supervision, and accumulated significant central bank reserves. Against this background, Uruguay now faces issues beyond those addressed to stabilize the economy. As the country pursues key postcrisis monetary and financial reforms, the analysis provided in this paper has a direct bearing on the ongoing efforts to move toward a fully fledged inflation-targeting regime and develop interest rates as monetary instruments, as well as on the preparedness of the financial system to deal with shocks, and the adequacy of current central bank reserves.

This paper provides a summary of the key policies that encourage dedollarization. It focuses on cases in which the authorities’ intention is to gain greater control of monetary policy and draws on the experiences of countries that have successfully dedollarized. Unlike previous work on the subject, this paper examines both macroeconomic stabilization policies and microeconomic measures, such as prudential regulation of the financial system. This study is also the first attempt to make extensive use of the foreign exchange regulation data reported in the IMF’s Annual Report on Exchange Arrangements and Exchange Restrictions. The main conclusion is that durable dedollarization depends on a credible disinflation plan and specific microeconomic measures.

Over the past decade, Cambodia has become Asia’s most dollarized economy. In contrast, dollarization in neighboring Lao P.D.R., Mongolia, and Vietnam has been either declining or broadly stable. Somewhat paradoxically, growing dollarization in Cambodia has occurred against the backdrop of greater macroeconomic and political stability. The usual motive, currency substitution, does not appear to have been a factor. As the volume of dollars increased over the years, so has the volume of riel. A strong inward flow of dollars related to garments sector exports, tourism receipts, foreign direct investment, and aid, has benefitted the dollar based urban economy. The riel based rural economy has, however, lagged behind. Given international experience in de-dollarization, a carefully managed market based strategy, supported by a continued stable macroeconomic environment is essential for Cambodia’s de-dollarization.

Theoretical and empirical analysis of de jure dollarization. With the persistent instability of international financial markets, emerging economies are exploring new ways to reduce exposure to capital flow volatility. Some analysts argue that financially open economies are best served by more flexible regimes, while others argue in favor of extreme exchange rate regimes that have a strong commitment to a fixed parity or dispense with an independent currency. The successful launch of the euro has made more realistic the prospect of replacing a national currency with a strong foreign one. Recent examples include the adoption of the US dollar by Ecuador and El Salvador. The introduction of a foreign currency as sole legal tender, termed full (de jure) dollarization, has been the center of much political and academic debate. This book provides a comprehensive analysis of the issues from both theoretical and empirical perspectives. The topics discussed include the role of balance sheet effects, the linkage between currency risk and country risk, the impact of dollarization on trade, financial integration and credibility, the implications of dollarization for the lender of last resort, and the institutional and political economy aspects of dollarization.

This paper reviews the literature on financial crises focusing on three specific aspects. First, what are the main factors explaining financial crises? Since many theories on the sources of financial crises highlight the importance of sharp fluctuations in asset and credit markets, the paper briefly reviews theoretical and empirical studies on developments in these markets around financial crises. Second, what are the major types of financial crises? The paper focuses on the main theoretical and empirical explanations of four types of financial crises—currency crises, sudden stops, debt crises, and banking crises—and presents a survey of the literature that attempts to identify these episodes. Third, what are the real and financial sector implications of crises? The paper briefly reviews the short- and medium-run implications of crises for the real economy and financial sector. It concludes with a summary of the main lessons from the literature and future research directions.
