Indicators for Brazil’s real exchange rate are calculated using different definitions
and focusing on what happened to such indices during the Cruzado plan. The real
effective exchange rate shows little appreciation in 1986 although the Cruzado/Dollar rate
did appreciate. The result is troubling in the light of a 25% decrease in Brazil’s trade surplus
in 1986. The paper argues that the net trade balance is explained by three variables: the real
effective exchange rate, domestic real income and real income in the rest of the world. An
econometric exercise shows strong income effects, effects that are ignored by the policy of
minidevaluations. The paper then looks at the suggestion of a dual exchange rate regime for
Brazil and concludes that such a system is likely to bring more instability to the economy.
An alternative proposal of a “planning approach” to the exchange rate policy is delineated.
