This study examines the challenges and issues facing policymakers in highly dollarized economies. Focusing on Cambodia, which achieved almost complete dollarization during 1991-95, the authors review recent developments in the literature on dollarization and examine the costs and benefits of dollarization in Cambodia, including the ensuing macroeconomic policy implications. They carry out an econometric estimation of cash foreign currency circulation in Cambodia in order to gauge the degree of dollarization. In addition to this analysis, the authors present a short description of Cambodia’s economic, financial, and structural background.

Dollarization - the holding by residents of a substantial portion of their assets in foreign-currency-denominated assets- is a common feature of developing and transition economies, and therefore typical of many countries with IMF - supported adjustment programs. This paper analyzes policy issues that arise-and various monetary strategies that may be pursued- when the monetary sector is dollarized, and it considers the implications that dollarization has for the design of IMF programs.

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 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.

This paper identifies key aspects that countries willing to officially dollarize must necessarily address. Based on country experiences, it discusses the critical institutional bases that are necessary to unilaterally introduce a new legal tender, describes the relevant operational issues to smooth the transition toward the use of the new currency, and identifies key structural reforms that are necessary to favor the sustainability over time of this monetary regime. The paper is aimed at providing preliminary guidance to policy makers and practitioners adopting official dollarization. The paper does not take a position on how appropriate this monetary arrangement is. Experiences from adopting dollarization in Ecuador, El Salvador, Kosovo, Montenegro, and Timor-Leste are illustrated briefly.

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.

Analyzes the costs and benefits of full dollarization, or the adoption by one country of another country's currency. Potential advantages include lower borrowing costs and deeper integration into world markets. But countries lose the ability to devalue, and become dependent on the U.S. Compares with currency board option.
