Optimum Currency Areas

An optimum currency area refers to the ‘optimum’ geographical domain having as a general means of payments either a single common currency or several currencies whose exchange values are immutably pegged to one another with unlimited convertibility for both current and capital transactions, but whose exchange rates fluctuate in unison against the rest of the world. ‘Optimum’ is defined in terms of the macroeconomic goal of maintaining internal and external balance. Internal balance is achieved at the optimal trade-off point between inflation and unemployment (if such a trade-off really exists), and external balance involves both intra-area and inter-area balance of payments equilibrium.
