This paper examines the relative demands for domestic and foreign currency deposits by residents of developing countries. A dynamic currency substitution model that incorporates forward-looking rational expectations is formulated and then estimated for a group of ten developing countries. The results indicate that the foreign rate of interest and the expected rate of depreciation of the parallel market exchange rate are important factors in the choice between holding domestic money or switching to foreign currency deposits held abroad. From an empirical standpoint, the forward-looking framework adopted here also turns out to be superior to the conventional currency-substitution model.

The level and trend in cash use in a country will influence the demand for central bank digital currency (CBDC). While access to digital currency will be more convenient than traveling to an ATM, it only makes CBDC like a bank debit card—not better. Demand for digital currency will thus be weak in countries where cash use is already very low, due to a preference for cash substitutes (cards, electronic money, mobile phone payments). Where cash use is very high, demand should be stronger, due to a lack of cash substitutes. As the demand for CBDC is tied to the current level of cash use, we estimate the level and trend in cash use for 11 countries using four different measures. A tentative forecast of cash use is also made. After showing that declining cash use is largely associated with demographic change, we tie the level of cash use to the likely demand for CBDC in different countries. In this process, we suggest that one measure of cash use is more useful than the others. If cash is important for monetary policy, payment instrument competition, or as an alternative payment instrument in the event of operational problems with privately supplied payment methods, the introduction of CBDC may best be introduced before cash substitutes become so ubiquitous that the viability of CBDC could be in doubt.

This update of the guidelines published in 2001 sets forth the underlying framework for the Reserves Data Template and provides operational advice for its use. The updated version also includes three new appendices aimed at assisting member countries in reporting the required data.

A stable money demand forms the cornerstone in formulating and conducting monetary policy. Consequently, numerous theoretical and empirical studies have been conducted in both industrial and developing countries to evaluate the determinants and the stability of the money demand function. This paper briefly reviews the theoretical work, tracing the contributions of several researchers beginning from the classical economists, and explains relevant empirical issues in modeling and estimating money demand functions. Notably, it summarizes the salient features of a number of recent studies that applied cointegration/error-correction models in the 1990s, and it features a bibliography to aid in research on demand for money.

The paper reviews recent theoretical and empirical developments in the analysis of informal currency markets in developing countries. The basic characteristics of these markets are highlighted, and alternative analytical models to explain them are discussed. The implications for exchange rate policy —including imposition of foreign exchange restrictions, devaluation, and unification of exchange markets— in countries with a sizable parallel market are also examined.

The growing importance of foreign currency deposits (FCDs) in some developing countries has raised numerous issues, particularly regarding the effectiveness of economic policies. This paper discusses factors that influence the emergence of FCDs and their impact on key macroeconomic relations. It is shown that while FCDs render more visible the changes in the economic structure occasioned by the shift in residents’ portfolio asset preferences, these changes essentially reflect currency substitution that often prevails prior to the introduction of FCDs. Moreover, FCDs provide only limited scope for effectively addressing the external and domestic imbalances that contribute to the growth in currency substitution.

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.

A Brookings Institution Press, the World Bank, and the International Monetary Fund publication The extensive reforms and liberalization of financial services in emerging markets worldwide call for cutting-edge strategies to capture the benefits of new investment opportunities. In Open Doors, a volume of papers from the third annual Financial Markets and Development conference, multidisciplinary financial sector experts analyze current economic and political trends and prescribe practical advice to the financial development community. The book addresses the key issues of concern regarding the emerging markets, including the trends, motivations, and scope of FDI in finance; policy options that will best capture the opportunities of foreign entry; and the role of foreign institutions in e-finance innovation. The authors focus on specific topics such as foreign participation in emerging market banking systems and securities industries, WTO policies and enforcement, the role of foreign banks, liberalization of insurance markets, the need for capital markets, and the policy, regulatory, and legal issues associated with e-finance. For policymakers and financial practitioners affected by the WTO's Financial Services Agreement, this timely book should be of particular interest.

In 2011 the World Bank—with funding from the Bill and Melinda Gates Foundation—launched the Global Findex database, the world's most comprehensive data set on how adults save, borrow, make payments, and manage risk. Drawing on survey data collected in collaboration with Gallup, Inc., the Global Findex database covers more than 140 economies around the world. The initial survey round was followed by a second one in 2014 and by a third in 2017. Compiled using nationally representative surveys of more than 150,000 adults age 15 and above in over 140 economies, The Global Findex Database 2017: Measuring Financial Inclusion and the Fintech Revolution includes updated indicators on access to and use of formal and informal financial services. It has additional data on the use of financial technology (or fintech), including the use of mobile phones and the Internet to conduct financial transactions. The data reveal opportunities to expand access to financial services among people who do not have an account—the unbanked—as well as to promote greater use of digital financial services among those who do have an account. The Global Findex database has become a mainstay of global efforts to promote financial inclusion. In addition to being widely cited by scholars and development practitioners, Global Findex data are used to track progress toward the World Bank goal of Universal Financial Access by 2020 and the United Nations Sustainable Development Goals. The database, the full text of the report, and the underlying country-level data for all figures—along with the questionnaire, the survey methodology, and other relevant materials—are available at www.worldbank.org/globalfindex.
