The purpose of this paper is to analyze the financial friction effect of non-performing loans (NPLs) on financial intermediation (FI) through empirical evidence from the Brazilian experience.


The authors develop a new variable, financial intermediation flow and a new indicator, FI, both measures of FI. To empirically test FI, the authors use a dynamic panel data framework that draws on 101 banks (December 2000 to December 2015).


An increase in NPL reduces FI. Thus, NPL amplifies financial friction in FI. This result holds in different time frames, such as the pre-crisis period, the crisis period and the post-crisis period.

Practical implications

The FI measure developed in this study offers the policymakers a possibility to monitor financial stability.


This study adds to this debate by proposing a measure of FI derived from financial flows. This measure allows one to estimate the role of NPL as a financial friction that can pose a threat to financial stability.
