Using a news‐based index of economic policy uncertainty (EPU), we find that EPU is positively associated with credit default swap (CDS) spreads and negatively associated with the number of liquidity providers in the CDS market. A 10% increase in EPU leads to an 8.4% increase in CDS spreads and a 4.0% decrease in the number of liquidity providers. Furthermore, the effects of EPU are persistent and robust after controlling for macroeconomic variables. Our results are also robust to different econometric methodologies. Overall, our findings suggest that, when EPU is high, investors find credit protection more costly and difficult to purchase.

PurposeThe purpose of this study is to examine the effects of the coronavirus disease 2019 (COVID-19) pandemic on sovereign credit default swap (CDS) spreads using a large sample of countries.Design/methodology/approachIn this paper, the authors use a wide set of the sovereign CDS data of 78 countries. To measure the magnitude of the COVID-19 pandemic, the authors use the daily change of confirmed cases collected from Our World in Data. They use panel regressions to estimate the impact of the COVID-19 pandemic on sovereign credit risk.FindingsThe authors show how sovereign CDS spreads have widened significantly in response to the COVID-19 pandemic. Based on the most conservative estimate, a 1% increase in COVID-19 infections leads to a 0.17% increase in sovereign CDS spreads. Furthermore, this effect is stronger for developing countries and countries with worse healthcare systems. Government policies partially offset the impact of the COVID-19 pandemic, although these same policies also lead to widening sovereign CDS spreads. Sovereign CDS spreads narrow dramatically several months after the outbreak of the COVID-19 pandemic. Overall, the results suggest that the ongoing COVID-19 pandemic has been a massive shock to the global financial stability.Originality/valueThis paper provides new evidence that COVID-19 widens sovereign CDS spreads. The authors further show that this widening effect is felt most strongly in developing economies.

We show that a news‐based measure of economic policy uncertainty (EPU) negatively forecasts momentum. A 1‐standard‐deviation increase in EPU is associated with a 1.11% decrease in risk‐adjusted momentum returns. The predictive power of EPU is robust after controlling for previously documented economic state variables and macroeconomic uncertainty. We provide an explanation for these results from the perspective of a fund flow‐induced trading mechanism and offer direct empirical support. The literature documents that momentum can be partially attributed to performance‐chasing mutual fund flows. We find that this flow‐induced mechanism functions more effectively in low EPU states, thereby generating stronger stock momentum.
