Bank Credit Channel of Monetary Policy in the UEMOA Zone: A TVP-VAR Approach

Abstract

The main objective of this article is to analyze the transmission of monetary policy in the WAEMU zone via the bank credit channel, using monthly data from January 1999 to December 2021. Methodologically, we apply a TVP-VAR model that allows coefficients to vary over time to reflect potential changes in time series dynamics. First, we find that the bank credit channel remains relatively weak in the union. Secondly, monetary policy shocks have evolved over time. Thirdly, the tertiary sector is relatively more responsive to monetary policy shocks than the primary and secondary sectors.
