Is Bank Portfolio Riskiness Procyclical? Evidence from Italy using a Vector Autoregression

This study analyzes the cyclical behaviour of the default rates of Italian bank borrowers over the last two decades. A vector autoregression (VAR) modelling technique is employed to assess the extent to which macroeconomic shocks affect the banking sector (first round effect). The VAR also helps to disentangle the feedback effects from the financial system to the real side of the economy. We find evidence of the first round effect and some support for the feedback effect which operates via the bank capital channel.
