Using a sample of forty developed and developing countries and employing staggered difference-in-differences models, we find that the sovereign credit risk measured by sovereign credit default swap spreads significantly increases after the COVID-19 pandemic outbreak, and the adverse effect is more pronounced for short-term credit risk. The reason is that the pandemic causes severe concerns about aggregate consumption contraction in addition to the fiscal capacity and the volatility of exports. We also find that fiscal stimuli stabilizing consumer spending alleviate the adverse effect of the COVID-19 pandemic, while debt relief does not matter. Overall, practitioners and policy makers should attach more importance to consumption and its recovery during the pandemic when making decisions. According to the World Health Organization (WHO) report, the new coronavirus pneumonia broke out in early 2020 and rapidly developed into a global epidemic that infected more than 80 million people in over 200 countries and regions by the end of 2020, causing severe economic contraction 1 . The COVID-19 pandemic has inspired a large body of literature to investigate its comprehensive effects on economic uncertainty (Altig et al., 2020) , unemployment, consumption (Cox et al., 2020; Chetty et al., 2020) , and the stock market (Baker et al., 2020a; Ding et al., 2021; Liu et al., 2021) , as well as the effect of governments' policy responses. The deterioration of economic development also arouses concerns about sovereign credit risk, yet only a few studies have explored the reaction of sovereign credit risk to the pandemic (Augustin et al., 2021) . Although the extant literature stresses the role of fiscal capacity or resilience to economic shock (Augustin et al., 2021) , we focus on the role of consumption in explaining the effect of the COVID-19 pandemic on sovereign credit risk for two reasons. First, consumption is one of the important determinants of sovereign credit risk (Augustin and Tedongap, 2016; Chernov et al., 2020) and declines sharply during the global epidemic. As consumption is a driver of economic growth, its contraction may further undermine a country's creditworthiness and hence trigger debt default in extreme cases. Baker et al. (2020b) argue that the COVID-19 pandemic-induced economic downturn is greatly 1 The report of International Labor Organization shows that 114 million jobs were reduced in 2020 compared to 2019. According to World Economic Outlook 2020 published by International Monetary Funds, global gross domestic product (GDP) of 2020 decreased by 3.5%. Several advanced economies such as the United States and Japan experienced the deepest economic recession since 2008 global financial crisis, with -3.5% and -4.8% GDP growth rate in 2020, respectively. In addition, the pandemic pushed up government debt dramatically. The statistic of Institute of International Finance shows that globally, the ratio of government debt to GDP increased from 90% in 2019 to around 105% in 2020. different from the 2008 financial crisis because the pandemic shock hits households' income and spending much more quickly. Theoretically, consumption contraction impairs a country's economic health and amplifies its sovereign credit risk reaction to the COVID-19 pandemic. Second, most countries have implemented stimulus packages to weather the pandemic shock on household spending, but their effects are still unclear in the literature on sovereign credit risk. Specifically, we ask three questions in this study: does the outbreak of the COVID-19 pandemic significantly increase sovereign credit risk? Does the pandemic shock undermine sovereign creditworthiness through the consumption contraction? Can fiscal stimuli aimed at stabilizing consumer spending mitigate the adverse effect of the global pandemic on sovereign credit risk? This paper studies the above questions using weekly data from forty countries over the period from January 2019 through August 2020. Following previous studies, we use sovereign credit default swap (CDS) spreads to measure sovereign credit risk 2 . Given that the consumption recovery of a country usually takes time after a negative shock (Augustin, 2018) , we also explore the changes in the spreads of 6-month and 1-year sovereign CDS respectively in addition to the spreads of 5-year sovereign CDS. This allows us to investigate the differential effects of the COVID-19 pandemic on a country's short-term and long-term credit risks. Our major findings are threefold. First, both the short-term and long-term sovereign credit risks of a country significantly rise after the outbreak of the COVID-19 pandemic, especially the former. Specifically, 5-year CDS spreads increase by 4.2% on average, while 1-year and 6-month CDS spreads increase by 8.7% and 13.5%, about 2.1 and 3.2 times of 5-year CDS spreads' change, respectively. The results suggest that the adverse impact is more pronounced for the short-term sovereign credit risk than for the long-term credit risk. In other words, the market is more concerned about the deterioration of sovereign credit risk in the short run. Second, using retail sales growth rate and pre-pandemic saving rate to measure the consumption shock, we find that a country's sovereign credit risk rises tremendously if it suffers a severe consumption contraction. The amplification effect of consumption still exists after controlling for the potential effects of fiscal capacity and trade volatility. Finally, the effect of income support policy depends on its coverage on income losses of the unemployed. Specifically, the adverse effect of the pandemic on sovereign credit risk is less pronounced in countries implementing a more generous income support policy. Our study mainly contributes to the literature in three aspects. First, we extend the literature by exploring the differential effects of the COVID-19 pandemic on long-term and short-term sovereign credit risks. The existing literature widely explores the effect of the COVID-19 pandemic on macroeconomic downturns (Baker et al., 2020b; Bartik et al., 2020; Chetty et al., 2020; Cox et al., 2020; Forsythe et al., 2020; Karger and Rajan, 2021) and financial markets (Baker et al., 2020a; Fahlenbrach et al., 2020; Ramelli and Wagner, 2020; Delis et al., 2021; Ding et al., 2021; Ftiti et al., 2021) , while only a few studies explore the effect on sovereign credit risk (Daehler et al., 2021) . Unfortunately, most previous studies focus on the long-term sovereign credit risk measured by the 5-year CDS spreads. However, Augustin (2018) stresses that a negative country-specific shock J o u r n a l P r e -p r o o f increases sovereign credit risk more for short maturities and less for long maturities. Thus, we extend the literature and provide effective evidence to Augustin (2018) by examining the adverse effect of the COVID-19 pandemic. Second, we document that the outbreak of the COVID-19 pandemic affects sovereign credit risk through consumption contractions in addition to limited fiscal capacity and export volatility. The limited literature seldom investigates how the COVID-19 pandemic affects sovereign credit risk, except for Augustin et al. (2021) , who investigate the role of fiscal capacity. They argue that limited fiscal capacity impairs resilience to economic shocks and increases a country's default risk during the pandemic. However, in addition to fiscal capacity, country-specific fundamentals such as consumption are also important determinants of sovereign credit risk (Augustin, 2018) . Furthermore, regarding the pandemic shock, consumption recovery is important for economic growth (Baker et al., 2020b) and hence is one of the focuses of fiscal relief policies (Chetty et al., 2020; Cox et al., 2020) . All these results suggest that consumption is important to understand the relationship between the COVID-19 pandemic and sovereign credit risk, while its role during the pandemic is still underexplored. Thus, we complement Augustin et al. (2021) by adding a new explanation of how the COVID-19 pandemic affects sovereign credit risk, which is useful for practitioners and policy-makers to optimize their decisions. Finally, considering that the pandemic does not break out at the same time across countries, we construct a staggered difference-in-differences (DID) model to address endogeneity issues and use econometric methods developed recently by Borusyak et al. (2021) , Callaway and Sant'Anna (2021) and Goodman-Bacon (2021) to address the timing J o u r n a l P r e -p r o o f 6 heterogeneity issues of the treatment effect. The staggered DID model is widely used in economic studies, while recent advances in econometric theory question its robustness and develop different modified econometric methods. To our knowledge, our study is one of the early to introduce them in economic studies. The rest of the paper proceeds as follows. Section 2 reviews the related literature. Section 3 presents our methodology, including the econometric models, the sample construction, the data sources and summary statistics. Section 4 presents the regression results and analyses, and Section 5 concludes. In the wake of the COVID-19 pandemic outbreak, a great number of studies have examined its economic effects at both the macrolevel and microlevel in the past one and a half years. This paper only focuses on studies that explore the effects on consumption and financial market risk. Regarding the effect on consumption, the literature finds that the COVID-19 pandemic causes severe consumption contraction worldwide. Although using different datasets 3 , Baker et al. (2020b) , Chetty et al. (2020) , and Cox et al. (2020) all find that the overall consumption in the United States during the early stage of the pandemic decreases significantly 4 , and they report several different findings. Chetty et al. (2020) find that the consumption contraction in the early month mainly relates to high-income households and then spreads to low-income households due to the consequent large job losses, while Baker et al. (2020b) and Cox et al. (2020) find that both the consumption contraction and its recovery are more significant for low-income households than for high-income households. Cox et al. (2020) also find that the spending decline is especially significant for nonessential items, namely, restaurants, hotel accommodations, and clothing and department stores. Using transaction data from UnionPay cards and QR scanners, Chen et al. (2021) find that daily offline spending on both goods and services in China declines by more than 40% in the early stage. Likewise, using bank accounts, Andersen et al. (2020) and Kubota et al. (2021) report that household spending falls significantly during the pandemic in Danish and Japan, respectively. However, the existing literature reports mixed evidence of the effectiveness of fiscal stimulus payments. Regarding the 2020 CARES Act and its follow-on policies in the United States, most studies find that stimulus payments to low-income households are useful to reverse consumption contractions sharply (Baker et al., 2020b; Chetty et al., 2020; Cox et al., 2020; Karger and Rajan, 2021) . Kubota et al. (2021) find that spending increases exclusively in the first month after the Japanese government launches a universal cash entitlement program. Liu et al. (2021) find that the large-scale digital coupon program issued by the Chinese government effectively stimulates household consumption. However, Chetty et al. (2020) stress that although stimulus payments to low-income households are useful to reverse consumption contraction sharply, only a tiny proportion of the increased spending flows to businesses most affected by the pandemic shock, suggesting that the J o u r n a l P r e -p r o o f recovery of overall consumption benefits economic sectors asymmetrically. Karger and Rajan (2021) find that consumer spending falls to normal two weeks after receiving fiscal stimulus payments. The literature on the effect of the COVID-19 pandemic on financial market risk extensively investigates the stock market's response. First, the literature studies financial factors that amplify or mitigate the effect of the pandemic on stock price volatility at the firm level. Using a sample of 61 economies, Ding et al. (2021) find that the supply chain's exposure to the COVID-19 pandemic and financial conditions (such as cash holdings and corporate debt) are key determinants of stock price reactions. Ramelli and Wagner (2020), focusing on firms in the United States, find that the major concern of the stock market is firms' supply chain exposure in the early stage of the pandemic and then turns to financial conditions when the disease spreads more widely. Furthermore, Fahlenbrach et al. (2021) also find a smaller stock price volatility for firms with less short-term debt in the United States. Xue et al. (2021) find that firms' stock prices in China fall significantly after the COVID-19 pandemic except those in the information technology and health care sectors. Second, the existing literature examines the market-level and sector-level reactions of the stock market. Focusing on the U.S. case, Baker et al. (2020a) find that the COVID-19 pandemic leads to unprecedented stock market uncertainty compared to other epidemics. Using S&P 500 Index returns, Delis et al. (2021) also document that the pandemic generates a significant negative impact on market return volatility, which is even greater than the global financial crisis. Focusing on the Chinese stock market, Ftiti et al. (2021) find that news about the number of deaths and cases related to COVID-19 leads to an increase in J o u r n a l P r e -p r o o f stock market volatility and a decrease in liquidity. In addition, Haddad et al. (2021 ), Kargar et al. (2021 , and O'Hara and Zhou (2021) find that the price and liquidity of corporate bonds decline significantly during the pandemic, and the transaction cost increases as well. A growing number of studies investigate the response of the financial market to the COVID-19 pandemic by focusing on sovereign and firm credit risks, which are usually measured by CDS spreads. Using the spreads of 5-year sovereign CDS, the existing literature finds that sovereign credit risk is positively correlated with the number of confirmed cases or deaths (Daehler et al., 2021) and the adverse effect is more pronounced in countries with small fiscal capacity and strong relief policies (Augustin et al., 2021) and is stronger before the European Central Bank's intervention (Ortmans and Tripier, 2021). Regarding corporate CDS spreads, the literature also reports an adverse effect of the pandemic, and it is more significant for nonfinancial firms, especially for firms with severe financial constraints, high stock volatility, low credit rating and profitability (Hasan et al., 2021; Liu et al., 2021) . The extant literature also explores the effect of public containment measures on the reaction of sovereign credit risk to the pandemic. For instance, Andries et al. (2021) find that stringent nonpharmaceutical measures amplify the erosion of sovereign creditworthiness under the pandemic shock. Taken together, the existing literature has examined the effect of the COVID-19 pandemic in multiple aspects and provides rich evidence and explanations. Although a few studies examine the response of sovereign credit risk, none study how the pandemic shock undermines sovereign creditworthiness, except for Augustin et al. (2021) . They argue that limited fiscal capacity impairs resilience to economic shocks and increases a country's J o u r n a l P r e -p r o o f default risk during the pandemic. Using data from thirty developed countries, they find that sovereign CDS spreads increase with the growth rate of COVID-19 infections, and the effect is more significant for fiscally constrained countries, suggesting that the pandemic affects sovereign credit risk through the fiscal channel. However, the literature on sovereign credit risk premiums stresses that economic growth and consumption are also important determinants of CDS spreads in addition to fiscal capacity (Augustin, 2018) , but both are underexplored. Recently, Baker et al. (2020b) , Chetty et al. (2020) , Cox et al. (2020) and other studies also find that consumption stabilization is the key to economic recovery from the epidemic. Thus, it is valuable to study the role of consumption in explaining the response of sovereign credit risk to the COVID-19 pandemic shock. To examine the effect of the COVID-19 pandemic on sovereign credit risk, we rely on a general DID model rather than examining the relationship between the number of COVID-19 cases and sovereign credit risk for two reasons. First, the number of COVID-19 confirmed cases highly depends on testing capability and accuracy, especially in the early stage. Second, slowing down the growth of COVID-19 cases may not alleviate the concern about the effect of the COVID-19 pandemic on sovereign credit risk because the effect may still exist but not disappear immediately 5 . Following Beck et al. (2010) and other studies, our general DID model is as follows: Ln(Spreadi,t) is the logarithm of sovereign credit risk, measured by sovereign CDS spreads of country i in week t. Prior studies suggest two major advantages of using sovereign CDS spreads as proxies for sovereign credit risk. First, sovereign CDS spreads reflect sovereign credit risk more adequately since the sovereign CDS market is usually more liquid than the sovereign bond market (Longstaff et al., 2011) . Second, CDS spreads on different sovereign entities are comparable due to their consistent maturity, restructuring clauses, and currency denomination. We use the spreads of 6-month (Spread6m), 1-year (Spread1y) and 5-year sovereign CDS (Spread5y) to capture the effect of the COVID-19 pandemic on both short-term and long-term sovereign credit risks. COVID19i,t is a dummy variable that captures whether the COVID-19 pandemic breaks out in country i. Specifically, if country i reports the first confirmed case in week t, COVID19i,t equals 1 in week t and consequent weeks and otherwise 0. The coefficient of Next, to examine the role of consumption, following Ding et al. (2021) , we extend the general DID model by including the interaction term of the consumption variable and COVID-19 as follows: where CONSUMi,t is the consumption change of country i in week t. Following previous studies, we measure consumption change in two ways. First, we consider the real change in consumption using the year-on-year changes in monthly total retail sales of consumer goods (Retail sales). Second, we use the saving rate in 2019 (Savings) as another proxy for consumption change since savings can function as a cushion for the abrupt income losses associated with the pandemic and hence alleviate the decline in household spending (Baker et al., 2020b; Cox et al., 2020; Kubota et al., 2021) . That is, unlike Retail sales, Savings is an indirect measure or expectation of future consumption change. We incorporate the interaction term between CONSUM and COVID-19 into Equation (1) and focus on the coefficient of the interaction term θ. If θ is negative and significant, we can conclude that the consumption contraction amplifies the adverse effect of the COVID-19 pandemic. Regarding the effectiveness of fiscal stimuli in restraining the adverse effect of the pandemic, we construct a new variable, Income, which is calculated by the weekly average of the income support index released by the Oxford Coronavirus Government Response Tracker (OxCGRT). The value of Income ranges from 0 to 2, with higher values related to more generous income support for unemployed individuals. We incorporate the interaction J o u r n a l P r e -p r o o f term of Income and COVID19, Income×COVID19, into Equation (1) and construct the following extended model: In addition to the control variables in X, we also control for the effect of other fiscal policies on debt relief by adding the interaction term of the weekly average of Debt Relief Index obtained from OxCGRT (Relief) and COVID19, namely, Relief ×COVID19 in X1. We focus on the coefficient of the interaction term φ and expect that income support for unemployed individuals is effective for weathering the pandemic shock if φ is significantly negative. Our sample consists of all countries and regions with data available from 1 January 2019 to 31 August 2020. We obtain data from multiple sources. First, we obtain the spreads of sovereign CDS from Markit. Markit provides the pricing data of sovereign CDS contracts for which the reference obligation is designated foreign debt of the sovereignty. We use sovereign CDS data denominated in the United States dollar in the basic regression results and sovereign CDS data denominated in the euro in the robustness checks to ensure that our results are consistent. Second, we obtain the data of both new and total confirmed COVID-19 cases for each country with sovereign CDS data available on the WHO website and the data of macroeconomic factors from the CEIC database and Bank for International Settlements (BIS) database. Finally, we obtain financial market data from the Chicago Board Options Exchange and Federal Reserve Bank and winsorize them at the 1% level on each tail to control for the effect of outliers. Then, after merging the above data and keeping J o u r n a l P r e -p r o o f all observations with data available, we construct a sample that has 3,926 country-week observations and covers 40 developing and developed countries. are all positive and statistically significant, at least at the 10% level, suggesting that sovereign credit risk increases significantly after the pandemic outbreak. Regarding economic magnitudes, the spreads of 6-month, 1-year, and 5-year sovereign CDS contracts increase by an average of 13.5%, 8.7% and 4.2%, respectively, after the outbreak of the new coronavirus disease. Furthermore, these results also show that the adverse effect of the pandemic shock is more pronounced for short-term credit risk than for long-term credit risk, suggesting that the market is more concerned about sovereign credit risk deterioration in the short run. This is consistent with Augustin (2018) , who predicts that the negative country-specific shock affects credit risk more for the short term and less for the long term. In addition, most regression results of our control variable are consistent with prior studies (Aizenman et al., 2013; Jeanneret, 2018) . For instance, sovereign credit risk is lower for a country with more international reserves, higher GDP, and lower currency depreciation and inflation. It is worth noting that the general DID model we construct is staggered since the date of the first confirmed case varies across countries. Recent econometric theories point out that timing heterogeneity may bias the two-way fixed effect estimate of the DID model (Borusyak et al., 2021; Callaway and Sant'Anna, 2021; Goodman-Bacon, 2021) . Thus, it is necessary to address whether and how our estimates of the general DID model are biased. We introduce three new methods developed by recent literature, while their common requirement on balanced panel data results in excluding three countries from the sample. We also focus on a DID model without control variables because the conclusion remains unchanged even when incorporating control variables into the model (Callaway and Sant'Anna, 2021) . First, we use Goodman-Bacon (2021) Third, we conduct an event study DID with a window of 21 weeks, i.e., starting from 10 weeks prior to the week when the first COVID-19 case is reported and ending 10 weeks after that. Following Callaway and Sant'Anna (2021) , the econometric model is as follows: where w is the relative week, and D w s are dummy variables equal to one for observations in the w th week. To avoid multicollinearity, D -1 is excluded. and statistically significant, with the highest increase of over 65%. All these results provide consistent evidence of the treatment effect of the COVID-19 pandemic outbreak on sovereign credit risk. Furthermore, the increasing posttreatment coefficients also show that the treatment effects grow over time. In sum, the event study DID analyses demonstrate that the parallel trend assumption is effective, and the treatment effects are significant and grow over time. We conduct six additional robustness checks. First, we examine whether the effect is different between developing and developed countries. Panel A and Panel B of Table 6 report the regression results for developing and developed countries, respectively. In Panel J o u r n a l P r e -p r o o f A, the results for developed countries are very similar to those for the whole sample in and Retail. These represent the changes in the number of visitors to residential areas, 7 We thank an anonymous reviewer for the valuable suggestions. J o u r n a l P r e -p r o o f workplaces, transit stations, parks and outdoor spaces, grocery and pharmacy stores, and places of retail and recreation, compared to the number of visitors before the pandemic, respectively. Residential is positively associated with the intensity of the pandemic shock, while the other five variables are negatively associated. The regression results in Table 8 show that the coefficients of Num_Cases, Stringency and Residential are positive, and the coefficients of Workplace, Transit, Outdoor, Grocery and Retail are negative, all more statistically significant and with absolute values decreasing over maturities. Fourth, we investigate the potential impact of the sovereign CDS contract liquidity 8 . Since detailed sovereign CDS volume data are not available publicly, we rely on Pan and Singleton (2008) who show that liquidity distribution varies across CDS contracts for different maturities. They find that sovereign CDS contracts at maturity points between 1 and 10 years are all traded actively, while the trading of non-sovereign CDS centres on a 5-year contract. The more even distribution of sovereign CDS contracts suggests that its potential impact is less likely to change our main findings. Nonetheless, we further provide additional regression results of 3-year and 10-year sovereign CDS contracts. The results in Table 9 show that the coefficients of COVID19 for 3-year and 10-year sovereign CDS spreads are significantly positive and greater for short-term contracts, suggesting that our results are robust. Fifth, the COVID-19 pandemic may increase firms' liquidity and credit risks, especially those in industries exposed to the shock, thereby exacerbating sovereign credit risk 9 . This indicates that the impact of the COVID-19 pandemic may vary in countries with different liquidity risks and credit risks. To capture the differential impacts, we compare the regression results of subsamples based on different risk measures. First, we use the ratio of current liabilities to total liabilities, and Altman Z score in 2019 at the country level to measure liquidity risk and credit risk before the pandemic, respectively. Second, we use the proportion of the output of hotel, accommodation, and transportation industries that are more likely to be hit by the pandemic as another measure for liquidity and credit risks. If a country's output depends more on these industries before the pandemic, the increase in liquidity and credit risks in such industries may cause deeper concern about massive default. Then, we define countries in the top quartile of risk indicators as high-risk-exposure countries and others as low-risk-exposure countries. The results in Table 10 show that the COVID-19 pandemic has led to a larger increase in sovereign CDS spreads for high-riskexposure countries than for other countries. That is, liquidity and credit risks, especially of specific industries, play an important role in pushing the increase of sovereign credit risk after the pandemic outbreak. Sixth, the standard errors of CDS spreads may be correlated because many countries are affected, either directly or through the negative spillover due to the interconnectedness of the economies. To control for the potential correlation, we adjust for t-statistics by clustering standard errors by group. Countries are divided into six groups, namely, Africa, Asia, Europe, the Middle East, North America, and South America, since countries geographically close are usually in the same trading block or share close economic relationships. The results in Table 11 show that the coefficients of COVID19 are all positive and significant at least at the 10% level, suggesting that our results remain unchanged. Panel A of Table 12 reports the estimation results of Equation (2). In Columns (1) show that the adverse effect of the pandemic is more significant in countries with large consumption shocks, suggesting that our results are robust. However, the findings above have to exclude alternative channels through which the J o u r n a l P r e -p r o o f pandemic shock affects sovereign credit risk. On the one hand, Augustin et al. (2021) propose a fiscal channel and argue that sovereign CDS spreads are more sensitive to COVID-19 cases for financially constrained governments. On the other hand, given that trade volatility is one of the important determinants of sovereign credit risk (Hilscher and Nosbusch, 2010) , the COVID-19 pandemic inevitably damages international trade and may affect sovereign CDS spreads through the trade channel. To exclude these two potential explanations, we construct two new variables. One is Fisconstraint, measured by the difference between revenues and expenditures as a percentage of GDP of a given country in 2019, namely, the fiscal balance. Generally, Fisconstraint is negatively associated with financial constraints. The other is Export, measured by the percentage changes in monthly exports. Then, we incorporate them and the interaction term between them and COVID19 into Equation (2). Likewise, since Fisconstraint is also predetermined during the sample period, the estimation is also dropped. We further identify whether the relief on income losses eases the pandemic-induced erosion of sovereign creditworthiness by stabilizing consumer spending. Generally, the J o u r n a l P r e -p r o o f relief on income losses is greater, and the consumption contraction is less. Thus, if consumption matters, the marginal effect of consumption contraction on sovereign CDS spreads is weaker for countries with more generous coverage on income losses. Table 14 reports the regression results of two subsamples using Retail sales and Savings as proxies for the consumption change, respectively. Overall, the results in Table 14 show that income support for unemployed individuals better mitigates the adverse effect in countries with lower coverage of income support than in other countries. This paper studies the effect of the COVID-19 pandemic on sovereign credit risk measured by sovereign CDS spreads, and examines whether the COVID-19 pandemic affects sovereign credit risk through the consumption channel. Using data from forty developing and developed countries and constructing staggered DID models, we find that the COVID-19 pandemic shock leads to a significant rise in sovereign credit risk. Averagely, after the report of the first confirmed case, 6-month, 1-year and 5-year CDS spreads increase by 13.5%, 8.7% and 4.2%, respectively, presenting a descending trend over maturities of sovereign CDS contracts. Further analyses show that the sovereign credit risk rises more if a country suffers greater negative growth of retail sales during the pandemic or has a lower aggregate savings rate before the pandemic outbreak. These results show that the consumption contraction is important to explain the effect of the COVID-19 pandemic in addition to the fiscal capacity and the volatility of exports. We also find that the adverse effect is less significant for countries with high coverage of income support for J o u r n a l P r e -p r o o f the unemployed, and hence add new evidence of the effectiveness of consumptionstabilized fiscal stimuli. Our results demonstrate that the pandemic-induced macroeconomic shock significantly damages a country's creditworthiness through the consumption contraction. It implies that the aggregate consumption recovery plays a crucial role in weathering the crisis associated with the COVID-19 pandemic. Furthermore, the increase of sovereign CDS spreads is more likely to push up the borrowing cost in the international financial markets, and thereby damage the financing capacity of a country. In addition, the fiscal stimulus policy is a double-edged sword, and its impact on sovereign credit risk is complicated. Fiscal stimuli may increase sovereign credit risk by adding more debt burden, but those related to income support for the unemployed may alleviate the adverse effect of the COVID-19 pandemic because they accelerate the recovery of consumer spending. Overall, practitioners and policy makers should realize the complexity of the effect of the COVID-19 pandemic when optimizing their decisions.
