This paper reviews the reserve requirement arrangements of sub-Saharan Africa, focusing on the differences between reserve requirements on domestic- and foreign-currency deposits. The reserve requirement systems in sub-Saharan Africa are relatively simple and transparent, but in some countries...

We analyze the costs and benefits of full dollarization compared to its closest alternative, a currency board, quantifying for Argentina where possible. Potential advantages include lower borrowing costs and deeper integration into world markets. One cost is the transfer of seigniorage to the...

We examine the implications of high degrees of dollarization for the choice of exchange rate regime and the information content of various monetary aggregates in developing countries. We conclude that a high degree of currency substitution argues for a more fixed exchange rate regime, while...

The paper presents a supervisory framework that addresses the vulnerabilities of partially dollarized banking systems. The tendency to underprice systemic liquidity risk and currency-induced credit risk creates vulnerabilities that need supervisory responses. The framework seeks to induce agents...

This paper presents theoretical work linking money demand to the perceptions of households about the risk that domestic currency may become inconvertible or that it may be devalued. An empirical investigation of the size of this effect is carried out using both cross section data and then...

The currency board arrangement and widespread dollarization of the Argentine economy since 1991 have laid the basis for domestic interest rates to converge to international levels. Although such a convergence has been observed for interest rates on bank deposits, interest rates on bank lending...

We develop a theoretical framework that encompasses four distinct motives for dollarization and discuss appropriate policy responses to help contain dollarization and its attendant risks. ""Moral hazard"" dollarization provides a clear case for prudential policy activism. However, prudential...

Rapidly rising dollarization and numerous related financial crises in recent years have heightened the need for policy action. This paper contributes to the policy debate by presenting a common analytic framework that examines the roots of de facto financial dollarization under different...
