The purpose of this study is to examine whether there is any genuine long run relationship between Consumer Price Index (CPI) and Non-Performing Loans (NPL). Using the logarithmic values of Consumer Price Index (CPI) inflation and Non-Performing Loans (NPL), different methodologies are employed in the analysis so that the robustness of unit roots and cointegration results is guaranteed. Based on the results, we consistently do not observe any genuine long run relationship between the two variables.
