Now that the impeachment has been confirmed, from here on signs of progress toward fiscal adjustment will tend to strengthen the real even more, but to the extent the Central Bank reacts by cutting the interest rate, it will be simultaneously reducing the attraction of capital inflows and encouraging fixed capital investments, prompting an increase in the current account deficit. Since capital movements happen faster than adjustment of the current account, initially appreciation will predominate, helping to curb inflation and strengthening the arguments for reducing the interest rate.
In a world characterized by price rigidity, movements in the nominal exchange rate are closely reflected in the real exchange rate, so they interfere in the competitiveness of exports and with the stimuli for substitution of imports. If no shocks occur that raise risks and cause large swings in the nominal exchange rate, the path of the real exchange rate will be less volatile. This is shown by the projections based on our real exchange rate model, which relies on the terms of trade and net external liability as explanatory variables.
