This paper addresses the challenges to prudential supervision in highly dollarized economies, where central banks and supervisors may be constrained in the use of standard money and financial policy tools. The study’s conclusions are the basis of an ongoing policy dialogue with IMF member...

Dollarization in Russia increased rapidly during the early 1990s, but failed to come down in the second half of the 1990s in spite of exchange rate stabilization. To explain this "dollarization hysteresis," this paper develops a model in which network externalities in the demand for currency can...

This paper explores how real dollarization (dollar indexing of wages), financial dollarization (dollar denomination of financial contracts), and monetary policy interact in a general equilibrium, new open-economy macroeconomics model with real shocks. Real dollarization is avoided as long as the...

Using a unique dataset with information on the currency composition of firms' assets and liabilities in six Latin-American countries, I investigate how the choice of exchange rate regime affects firms' foreign currency borrowing decisions and the associated currency mismatches in their balance...

In the last decade, a group of Latin American countries (Bolivia, Paraguay, Peru, and Uruguay) experienced a gradual, yet sustained decline in financial dollarization. This paper documents the stylized facts and uses a standard VAR approach to examine the drivers of both deposit and credit...

Peru has successfully pursued a market-driven financial de-dollarization during the last decade. Dollarization of credit and deposit of commercial banks - across all sectors and maturities - has declined, with larger declines for commercial credit and time and saving deposits. The analysis...

A key issue in creating a new currency union is setting the rates to convert national currencies into the new union currency. Planned unions in the Gulf region and Africa are seeking methods to set the conversion rates when their new currencies are created. We propose a forward-looking...

De facto (unofficial) dollarization, defined as the holding by residents of assets and liabilities denominated in a foreign currency, is a policy concern in an increasing number of developing economies. This paper addresses the dollarization debate from this perspective, with the goal of setting...
