Institui？？es fortes, moeda estável e Banco Central do Brasil aut？nomo

the article discusses the autonomy of brazil's central bank and its potential relationship to the national currency's stability. beyond the government budget balance and the central bank's autonomy, we seek to demonstrate that the currency's stability also depends on the bank's own political and institutional stability. due to a gap in the literature, which has focused little attention on the political conditions and economic motivation by which important steps were taken towards achieving autonomy, we analyze the relations between autonomy and stability from a historical-institutional perspective. we call attention to the cyclical nature of the brazilian economy, which alternates developmentalist policies and stabilization policies and thereby alters the central bank's role and degree of autonomy.
