This paper analyses the relationship between interest rate and inflation in Namibia. The objective is to test whether the Fisher hypothesis holds in the long run. Using monthly data for the period 1992:01 – 2011:12, the paper employed time series techniques, namely, unit root tests and cointegration test. The unit root test reveales that the series are non stationary. The cointegration test shows that there is no cointegration among the variables. Hence, the long run relationship between inflation and interest rate is non existent. The study rejects the Fisher hypothesis in the Namibian context. In the absence of cointegration the study could not proceed with Granger causality test.
