De Nicolo, Honohan, and Ize assess the benefits and risks associated with dollarization of the banking system. The authors provide novel empirical evidence on the determinants of dollarization, its role in promoting financial development, and on whether dollarization is associated with financial instability. They find that: The credibility of macroeconomic policy and the quality of institutions are both key determinants of cross-country variations in dollarization. Dollarization is likely to promote financial deepening only in a high inflation environment. Financial instability is likely higher in dollarized economies. The authors discuss the implications of these findings for financial sector and monetary policies.

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.

A very commonly observed phenomenon in developing and emerging market economies is the use of another country’s currency (whether the US dollar or another currency) in lieu or in addition to the local currency. The most common type of this financial phenomenon is partial (de facto) dollarization where foreign currencies are used side by side with local currency for saving and borrowing purposes in addition to serving as medium of exchange. Governments in these countries have been encouraging dollarization for years by allowing their citizens to save and borrow from local banks in foreign currency. Yet the existence of multiple currencies on banks' balance sheets on both the asset and liability side poses risks to the health and stability of the banking system. This book evaluates the practical aspects of partial dollarization in countries such as Turkey, South Korea, Peru, and Cambodia among others. Starting with the origins of the phenomenon, the impact on banking systems and financial depth of the credit markets are discussed along with risks to the banking systems. Challenges faced by Central Banks and banking regulators are evaluated using recent country studies.

This book sheds light on the dollarization trends of four transitional economies in Southeast Asia: Cambodia, Lao PDR, Myanmar, and Vietnam. Moving beyond the tendency to focus on the Latin American experience of dollarization and prolonged high inflation, the chapters in this book compare how payment dollarization has been more persistent than other types of dollarization in this region due to network externalities. The book illustrates that dollarization started in the underdeveloped financial system in these countries and that dollarization interacted with financial development, which is in contrast to dollarization in Latin America. This project extends the frontiers of empirical studies on dollarization. It will be of interest to students, researchers and policy makers concerned with dollarization and economics in Southeast Asia.

An increasing share of bank deposits in developing countries is denominated in foreign currency. This trend may have adverse implications for the cost and availability of credit.

Using a newly complied and extended database from International Financial Statistics, and applying different panel-regression techniques, this paper documents the evolution of households’ and firms’ dollarization over the past decade. We assess the macroeconomic determinants of dollarization for households and firms and explore differences between high and low-income countries. We find that households’ and firms’ dollarization in loans and deposits are weakly explained by the currency substitution model, except in low income countries, where inflation plays a significant role. Instead, market development variables such as financial deepening, access to external debt and FX finance as well as other market considerations are key to explain the dynamics of deposits and loans dollarization, regardless of the level of income.These factors can account for a significant fraction of the dollarization, but using a variance decomposition model, there is evidence that a non-negligible portion has yet to be explained. This suggests that there are key determinants for household and firm dollarization that are not fully captured by traditional macroeconomic explanatory variables.

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.
