To help overcome its financial crisis, Russia is being urged to create a
currency board, which has met with success in other countries such as
Argentina, Estonia, and Hong Kong. This study explains what a currency
board is and how it differs from a central bank, and examines the
advantages and disadvantages of each type of arrangement. The author
concludes that currency boards may be quite attractive to small, open
economies and a useful prop in those emerging from a very deep
macroeconomic crisis, but that their disadvantages outweigh these
attractions in most large countries.
