Heterogeneity in corporate debt structures and the transmission of monetary policy

A B S T R A C T We study how differences in the aggregate structure of corporate debt affect the transmission of monetary policy in a panel of euro area countries. We find that standard policy tightening shocks raise the cost of loans relative to corporate bonds. In economies with a high share of bond finance, the resultant rise in the overall cost of credit is less pronounced as a smaller portion of corporate debt is remunerated at the loan rate and firms further expand their reliance on bonds. In economies with a low share of bond finance, the rise in the cost of credit is reinforced by a shift in the composition of debt towards bank loans. As a consequence, a higher bond share goes along with a weaker transmission of short-term policy rate shocks to real activity. By contrast, the real effects of monetary policy shocks to longer-term yields strengthen with the share of bond finance in the economy. (c) 2021 Elsevier B.V. All rights reserved.
