We assess the e¤ect and the timing of the corporate arm of the ECB quantitative easing (CSPP) on corporate bond issuance. Because of several contemporaneous measures, to isolate the programme e¤ects we rely on one key eligibility feature: the euro denomination of newly issued bonds. We …nd that the signi…cant increase in bonds issuance by eligible …rms is due to the CSPP and that this e¤ect took at least six months to unfold. This result holds even when comparing …rms with similar ratings, thus providing evidence that unconventional monetary policy can foster a …nancing diversi…cation regardless of …rms' risk pro…le. We also highlight the impact of the programme on the real economic activity. The evidence suggests that while all …rms increased investment in capital expenditures and intangible assets, the CSPP induced eligible …rms to invest in marketable and equity securities, to repurchase their own stocks, to hold cash and to carry out short-term investment.
