This paper addresses the issue of bank lending channel in Brazil using monthly aggregate data in the range 1995/2010, in a structural cointegrated VAR. Following techniques previously used by Huelsewig et al (2005) and Walsh and Wilcox (1995) and applying a VECM model, it is estimated the response of bank loans to a monetary policy shock and to identify demand and supply of loans. The results show evidence of the operation of the credit channel in Brazil, and through the historical decomposition of the variance observes the role of credit in the performance of industrial product during recent phases of expansion and contraction of the Brazilian economy.
