Abstract

We show that the COVID-19 pandemic triggered a surge in the elasticity of non-financial
corporate to sovereign credit default swaps in core EU countries, characterized by strong fiscal capacity. For peripheral countries with lower fiscal capacity, the pandemic had essentially noimpact on such elasticity. This evidence is consistent with the disaster-induced repricing of
government support, which we model through a rare-disaster asset pricing framework with
public guarantees and defaultable sovereign debt. The model parameters we calibrate from the data confirm that government guarantees in the core were larger than in the periphery, which implies that fiscal capacity buffers provide relief to firms’ financing costs.
