From purchases to exit: central bank interventions in corporate debt markets

No 3055, Working Paper Series from European Central Bank

Abstract: Central banks increasingly act as market-makers-of-last-resort, yet the impact and exit of such interventions remain poorly understood. Using euro-area data, we analyze the cycle of market freeze, intervention, and exit in short-term debt markets. A run on money market funds (MMFs) triggered a collapse in these markets in March 2020. Firms replaced only 27% of lost funding through credit lines. The European Central Bank intervened, fully replacing MMFs for some firms and allowing them to issue more debt at lower rates and longer maturities. After the ECB’s exit, more-exposed firms faced higher yields (+20.2 bps), reduced MMF investments, and fewer new relationships. Credit line take-up did not materially change post-exit. JEL Classification: G11, G23, G32, E5
