Heterogeneous Effects of Unconventional Monetary Policy on Loan Demand and Supply. Insights from the Bank Lending Survey

Abstract: This paper analyzes the bank lending channel and the heterogeneous effects on the euro area, providing evidence that the channel is indeed working. The analysis of the transmission mechanism is based on structural impulse responses to an unconventional monetary policy shock on bank loans. The Bank Lending Survey (BLS) is exploited in order to get insights on developments of loan demand and supply. The contribution of this paper is to use country-specific data to analyze the consequences of unconventional monetary policy, instead of taking an aggregate stance by using euro area data. This approach provides a deeper understanding of the bank lending channel and its effects. That is, an expansionary monetary policy shock leads to an increase in loan demand, supply and output growth. A small north-south disparity between the countries can be observed.
