The CSPP impact on non-financial firms’ cost of borrowing and debt choice

In this study, we examine the impact of the European Central Bank’s (ECB) corporate sector purchase programme (CSPP) on euro area non-financial firms’ cost of borrowing and choice between bank and public debt. Using a large sample of corporate bonds and syndicated loans closed between 2000 and 2019, we find that the CSPP reduced corporate bond spreads significantly, in both announcement and implementation periods. Findings also suggest that the CSPP had a positive spillover effect into the syndicated loan market during the implementation period. Our results show that there is a substitution effect between eligible bonds and equivalent loans, with non-financial firms choosing to use more corporate bonds than syndicated loan deals after the CSPP announcement, and that this effect is more important for non-switchers, those that may have more difficulty in accessing the bond market. Finally, we provide evidence that, when controlling for the CSPP, borrowers that choose corporate bonds are larger, more profitable, and have larger growth opportunity sets; and switchers with high agency costs of debt prefer bank debt.
