This paper evaluates the usefulness of a currency board regime based on Argentina’s experience.  Argentina adopted the currency board in March 1991 to put an end to a long history of large macroeconomic imbalances and high inflation that culminated in the hyperinflation process of 1989-91.  The regime has been extremely successful in restoring macroeconomic stability and ensuring low inflation.  The adoption of a tight fiscal stance, and of sound polices to strengthen the financial system were critical to ensure the resilience of the economy to respond to adverse external shocks. The paper will argue that a strict exchange rate rule like the one used in Argentina can be a strong alternative to other exchange rate regimes to ensure macroeconomic stability in a globalized world with highly integrated capital markets.
