In this paper, the natural rate of interest for the brazilian economy was estimated between end of 2001 and second quarter of 2010 based on two models, being the first the method suggested by Laubach and Williams and the second, the one suggested by Mesónnier and Renne, which is a altered version of the first one, that according to authors allows a more transparent and robust estimation. In both models, the natural rate of interest is estimated jointly with potential output, using the Kalman filter, in a state-space format. The two models estimates have not presented a significant difference, which generates more confidence in the produced results. Considering the period of more interest of this paper (after 2005), the estimates show that the natural rate of interest has been falling in the brazilian economy since 2006. The measurement of the natural rate of interest, additionally, allowed an assessment of the monetary policy implemented by the Brazilian Central Bank in the last years through the interest rate gap concept. In general, the analysis has showed a more conservative Central Bank between 2001 end and 2005 and neutral since then. This conclusion differs from others analysis, specially for the first period.
