The impact of the ECB's monetary policy on corporate borrowing costs

This paper examines the impact of the ECB's monetary policy on corporate borrowing costs. We use an event study method to assess and compare the effects of both conventional and unconventional monetary policy on Germany and French corporate bond market (credit spreads). The sample of our research consists of daily data collected during the period from 04 January 1999 to 27 February 2015. This period spans the pre-crisis which begins when the ECB has launched the Economic and Monetary Union (EMU) and became responsible for the monetary policy in the euro area. We find significantly negative relation between conventional surprise and corporate credit spreads. Moreover, we find that a raise in German non-financial credit spreads and French credit spreads domestic in response to the SMP announcement. The OMT lowers the German non-financial credit spreads, while it raises German bank credit spreads and French corporate credit spreads both domestic and bund for two sectors. Finally, the LTROs are associated with a raise in corporate credit spreads. Our findings are confirmed in robustness checks by changing the non-standard monetary policy announcements with monetary policy event dummies used as one variable.
