Monetary Policy Surprises and Corporate Credit Spreads

Abstract

We study the effects of monetary policy surprises (MPSs) on corporate credit default swap (CDS) spreads. Using high-frequency surprises around Federal Open Market Committee (FOMC) announcements, we find a negative relation between changes in unexpected expansionary monetary policy and changes in CDS spreads using both panel regressions and time-series regressions. More importantly, we show that there is a strong cross-sectional effect of MPSs on CDS spreads. Unexpected expansionary monetary policy reduces the flight-to-safety and flight-to-liquidity phenomenon: The credit spread between investment-grade and high-yield CDSs narrows significantly following an unexpected monetary policy. Finally, we show that monetary policy affects CDS spreads through cash flow, financial constraints, and risk channels.
