The Real Effects of Credit Ratings on Credit Default Swap Market: The Sovereign Ceiling Channel
This preprint empirically analyzes how credit rating downgrades affect CDS spreads using difference-in-differences methodology.
What it examines
This study examines how sovereign downgrades mechanically force firm rating downgrades using the sovereign ceiling rule. It employs difference-in-differences analysis with matching techniques to isolate the impact of these exogenous rating changes on CDS spreads, focusing on firm characteristics and macro factors.
What it concludes
The findings show that exogenous rating downgrades lead to significant increases in CDS spreads for treated firms, indicating that nonpublic information affects market pricing. This research supports improved risk management and investment strategies, with future studies suggested in varying economic contexts.
Evidence objects
The study finds that sovereign credit rating downgrades induce a CDS market effect, with firms at or above the sovereign rating experiencing a $$23.08%$$ increase in spreads versus other firms.
