The main objective of this paper is to examine the exchange rate policy adopted since the beginning of the Real Plan and to test its credibility. This paper analyses theoretically the trade-offs between fixed exchange rate regimes and target zones. The conclusion is that the choice of target zones was appropriate, since it reduces the exposure of the economy to exogenous shocks, like the Asian crises, which originated a major speculative attack against the domestic currency. This is so because target zones help to reduce the interest rates diferentials, a basic measure of credibility. An empirical investigation, aimed at investigating the behavior of exchange rates during the Real Plan was conduct. Two measures of volatility were used: asymptotic and conditional variance. The results showed that the behavior of the bands in Brazil is credible, because it was found a negative correlation between expected realignments and the movements within the bands.
