ABSTRACT
The main objective of this study was to determine the effectiveness of credit as a channel of monetary policy transmission in Brazil, based on empirical evidence for the period 2002-2012, when the ratio of credit to GDP grew substantially. With that purpose, we estimated different VAR models and analyzed the impulse-response functions and the decomposition of the variance of errors. Credit demand and supply were determined by shocks in the actual volume of credit and market interest rates, respectively. The results indicated the existence of the credit channel. Thus, it is advisable that the monetary authorities give more attention to the effects of monetary policy at the level of market interest rates, since the effect of monetary policy on it enhances the response of the real economy.
