A teoria econômica aponta uma inter-relação entre os resultados deste mercado e a estrutura macroeconômica. Através da metodologia de Rigobon e Sack (2003), o presente estudo avalia o impacto contemporâneo do mercado acionário sobre a taxa Selic de juros. A contribuição deste trabalho é a de encontrar indícios de que um choque não esperado que cause 1% de valorização no retorno do mercado acionário provoque uma queda de 0,019% na taxa Selic de juros. Os resultados parecem ser de pequena escala, quando comparados com os valores obtidos em outros países. / The Brazilian stock market has shown consistent growth over the last few years. Economic theory points to an interrelationship between the results of this market and the macroeconomic framework in previous studies. Through the methodology presented by Rigobon and Sack (2003), this study assesses the contemporary impact of the stock market on the Selic interest rate. The contribution of this work is to find evidence that an unexpected shock causes of 1% appreciation in the stock market return causes a decrease of 0.019% in the Selic interest rate. The results appear to be not significant when they are compared to results from other countries.
