Sovereign default and debt renegotiation

This paper develops a small open economy model to study sovereign default and debt renegotiation for emerging economies. The model features both endogenous default and endogenous debt recovery rates. Sovereign bonds are priced to compensate creditors for the risk of default and the risk of debt restructuring. The model captures the interaction between sovereign default and ex post debt renegotiation. We find that both debt recovery rates and sovereign bond prices decrease with the level of debt. In a quantitative analysis, the model accounts for the debt reduction, volatile and countercyclical bond spreads, countercyclical trade balance, and other empirical regularities of the Argentine economy. The model also replicates the dynamics of bond spreads during the debt crisis in Argentina.     

Sovereign bond spreads determinants in Latin American countries: Before and during the XXI financial crisis

This paper aims to identify the main determinants of sovereign bond spreads in seven Latin American countries and verify the existence of contagion effect over these markets during the last financial crisis. We apply a panel data framework and find that the inflation, terms of trade ratio and the external debt and international reserves (both as percentage of GDP) are key drivers of sovereign bond spreads. Moreover, we test the crisis impact over emerging economies. Our results show that the crisis has a statistically significant impact on the EMBIG spreads since 2008.     

Does governing law affect bond spreads?

Controlling for bond and issuer characteristics, bond spreads are expected to be equal across different legal jurisdictions, and differences are expected to disappear through arbitrage. However, an analysis of 490 U.S. dollar–denominated bonds issued by 53 emerging market sovereigns during 1990–2015 reveals that after the financial crisis of 2008, launch spreads of sovereign bonds issued under U.K. law have been higher than those issued under U.S. law, by 130 basis points for BB+ bonds and 175 basis points for B− bonds. This effect was not significant for investment grade bonds. On average, bonds issued under U.K. law had weaker ratings and shorter tenors post-crisis. The post-crisis impact of governing law on sovereign bond spreads is not explained by collective action clauses, or first-time bond issuances. Instead, the difference seems to be related to the perception that U.S. law offers stronger investor protection, and that the investor base for bonds issued under U.S. law is larger than that for bonds issued under U.K. law. The difference in spreads persists in the secondary market even after 180 days, perhaps because of the lack of liquidity, as investors tend to buy and hold these more attractive bonds on a longer-term basis.     

Emerging market sovereign bond spreads: Estimation and back-testing

We estimate sovereign bond spreads of 28 emerging economies over the period January 1998–December 2011 and test the ability of the model in generating accurate in-sample predictions for bond spreads. The impact and significance of explanatory variables on spreads vary across regions and periods. During crisis times, good macroeconomic indicators are helpful in containing spreads, but less than in non-crisis times, possibly reflecting the impact of extra-economic forces on spreads when a financial crisis occurs. For some economies, in-sample predictions of the monthly changes in spreads obtained with rolling regression routines are more accurate than those obtained with random guessing.     

Emerging market bond spreads and sovereign credit ratings: reconciling market views with economic fundamentals

This paper uses a panel data estimation of a simple univariate model of sovereign spreads on ratings to analyze statistically significant differences between actual spreads and ratings-based spreads. When such deviations are significant, we find that ‘excessively high’ spreads are on average followed by episodes of spread tightening 1 month later rather than credit downgrades. In contrast, observations with ‘excessively low’ spreads are on average followed by rating upgrades 3 months later rather than episodes of spread widening. The paper also illustrates how significant disagreements between market and rating agencies’ views can be used as a signal that further technical and sovereign analysis is warranted. For instance, we find that spreads were ‘excessively low’ for most emerging markets before the Asian crisis. More recently, spreads were ‘excessively high’ for a number of emerging markets.     

External Public Debt,Trade Linkages and Contagion During the Eurozone Crisis

Against the backdrop of the contagion literature, the paper analyses the impact of financial and trade linkages on sovereign bond spreads in the Eurozone crisis. Using quarterly data for a sample of EMU countries during the period 2000–13, we estimate fixed‐effect panel models with Driscoll and Kraay standard errors that are robust to general forms of spatial and temporal dependence. Our main results can be summarised as follows: first, we suggest that the ‘sudden stop’ of capital inflow towards the peripheral sovereign debt triggered a re‐segmentation of financial markets and economic systems along national borders, with negative implications for risk‐sharing and the efficient allocation of capital. The ‘home bias’ effect – that is the increase in the share of sovereign debt held by domestic banks – worsened the country‐specific risk because the twin crisis (sovereign and banking) began to be conceived as more closely intertwined within countries than before. Second, the structure of international trade helps to account for the geographic scope of contagion, even after controlling for macroeconomic and fiscal vulnerabilities. Finally, the ‘substitution effect’ of public debt securities of stand‐alone emerging countries has affected more the sovereign spreads in the core than in the periphery.     

Identifying risks in emerging market sovereign and corporate bond spreads

This paper investigates the systematic risk factors driving emerging market (EM) credit risk by jointly modeling sovereign and corporate credit spreads at a global level. We use a multi-regional Bayesian panel VAR model, with time-varying betas and multivariate stochastic volatility. This model allows us to decompose credit spreads and build indicators of EM risks. A key result is that indices of EM sovereign and corporate credit spreads differ because of their specific reactions to global risks (risk aversion, liquidity and US corporate risk). For example, following Lehman's default, EM sovereign spreads ‘decoupled’ from the US corporate market, whereas EM corporates ‘recoupled.’     

Yield spreads on EMU government bonds — How the financial crisis has helped investors to rediscover risk

This study analyses the determinants of EMU member states’ government bond yield spreads from January 2000 until September 2010. Using a dynamic panel regression approach, the authors show that before the outbreak of the financial crisis investors generally ignored fundamental sovereign bond risk factors. However, with the beginning of the financial crisis yield spreads for many member countries escalated. The results indicate not only that investors began to re-evaluate countries’ credit risks (measured by projections of debt-to-GDP ratios), but also that risk aversion in the markets, which increased significantly during the crisis, became a major determinant of sovereign bond spreads.     

The role of country-specific fundamentals in sovereign CDS spreads: Eastern European experiences

We investigate the determinants of sovereign CDS spreads on a sample of Eastern European data. A dynamic hierarchical factor model is used to aggregate information in indicators of economic fundamentals. CDS spreads are regressed on forecasts of factors. We find that domestic fundamentals explain more of CDS spread variance than global factors, largely due to their ability to explain differences in sovereign risk across countries. The effects on CDS spreads are found to be time-varying. In terms of economic significance, the factor of institutional-political strength stands out. We apply the model to study CDS spreads of Poland, Russia and Turkey.     

Emerging market sovereign bond spreads and shifts in global market sentiment

The paper studies how the relationship between emerging market sovereign bond spreads, economic fundamentals and global financial market conditions differs across three regimes of global market sentiment. Following the identification of periods characterized by low, medium and high volatility in financial markets, we analyze the behavior of spreads from three different angles. First, we demonstrate that the cross-country correlation of spreads increases in high-volatility regimes, implying that countries cannot fully decouple from developments in other emerging markets during periods of distress. Second, using the interactions of several domestic and global variables with the probabilities of each regime prevailing in a given period as the explanatory variables of spreads, the fixed effects panel estimation shows that while country-specific fundamentals are important determinants of spreads in each regime, the importance of global financial conditions increases in high-volatility periods. Third, we show that countries can benefit from stronger fundamentals in the form of lower exposure of their sovereign spreads to unfavorable regime shifts in global market sentiment.     

Long-duration bonds and sovereign defaults

This paper extends the baseline framework used in recent quantitative studies of sovereign default by assuming that the government can borrow using long-duration bonds. This contrasts with previous studies, which assume the government can borrow using bonds that mature after one quarter. We show that, when we assume that the government issues bonds with a duration similar to the average duration of sovereign bonds in emerging economies, the model generates an interest rate that is substantially higher and more volatile than the one obtained assuming one-quarter bonds. This narrows the gap between the predictions of the model and the data, which indicates that the introduction of long-duration bonds may be a useful tool for future research about emerging economies. Our analysis is also relevant for the study of other credit markets.     

MODELING SOVEREIGN RISKS: FROM A HYBRID MODEL TO THE GENERALIZED DENSITY APPROACH

Motivated by the European sovereign debt crisis, we propose a hybrid sovereign default model that combines an accessible part taking into account the evolution of the sovereign solvency and the impact of critical political events, and a totally inaccessible part for the idiosyncratic credit risk. We obtain closed‐form formulas for the probability that the default occurs at critical political dates in a Markovian setting. Moreover, we introduce a generalized density framework for the hybrid default time and deduce the compensator process of default. Finally, we apply the hybrid model and the generalized density to the valuation of sovereign bonds and explain the significant jumps in long‐term government bond yields during the sovereign crisis.     

Optimal reserve management and sovereign debt

Most models currently used to determine optimal foreign reserve holdings take the level of international debt as given. However, given the sovereign's willingness-to-pay incentive problems, reserve accumulation may reduce sustainable debt levels. In addition, assuming constant debt levels does not allow addressing one of the puzzles behind using reserves as a means to avoid the negative effects of crisis: why do not sovereign countries reduce their sovereign debt instead? To study the joint decision of holding sovereign debt and reserves, we construct a stochastic dynamic equilibrium model calibrated to a sample of emerging markets. We obtain that the reserve accumulation does not play a quantitatively important role in this model. In fact, we find the optimal policy is not to hold reserves at all. This finding is robust to considering interest rate shocks, sudden stops, contingent reserves and reserve dependent output costs.     

Accounting for sovereign tail risk in emerging economies: The role of global and domestic risk factors

This paper evaluates the role of global and domestic risk factors in explaining sovereign tail risk for 18 emerging economies. Sovereign tail risk is defined as the likelihood of a sharp rise in sovereign credit risk. We find that both global and domestic risk factors contribute significantly to sovereign tail risk, with explanatory power increasing with the severity of tail risk in a non-linear fashion. Indeed, their contributions have become stronger following the global financial crisis. In particular, global liquidity conditions, commodity prices and economic growth are ranked as the major risk factors for sovereign tail risk among the EMEs.     

The impact of macroeconomic announcements on emerging market bonds

This paper examines how emerging market bonds react to macroeconomic announcements. Global bond spreads respond to rating actions and changes in U.S. interest rates rather than domestic data and policy announcements. All announcements affect market volatility. Macroeconomic data and policy announcements reduce uncertainty and stabilize spreads, while rating actions cause greater volatility. Results are robust to country-specific and panel analyses, assuming conditional variance and controlling for the surprise content of news. In subsamples, announcements matter less for countries with more transparent policies and higher credit ratings. In a crisis, rating actions become less important, and investors focus on simple and timely indicators.     

Banking union with a sovereign virus

Despite the experience of the ongoing sovereign debt crisis, European banks continue to hold large amounts of bonds from their home governments. This ties the fates of the sovereign and the banks together, leading to the disruptive self-reinforcing feedback loops that brought the euro area to the brink of collapse. This article addresses how banks can be weaned off of their massive investments in their home government’s bonds.     

Sovereign debt and corporate borrowing costs in emerging markets

We document that the corporate sector faces higher borrowing costs when the external debt of the public sector is higher. By contrast, no significant relationship is found between domestic public debt and corporate borrowing costs. An increase in sovereign debt by one standard deviation from its sample mean is associated with 9% higher loan yield spreads. The correlation is considerably higher in countries with weak creditor rights and past sovereign default episodes. Overall, these findings suggest substantial adverse linkages between public external debt and private financing costs.     

Institutional quality and sovereign credit default swap spreads

We examine how the quality of political, legal, and regulatory institutions impacts sovereign risk premia. An improvement in institutional quality significantly lowers a country's sovereign credit default swap (CDS) spread, even after controlling for domestic and global macroeconomic factors. The incremental effect of institutional quality may also be economically important in explaining the variations in the level of sovereign CDS spreads. The basic results are robust to alternative model specifications, samples, control variables, measures of institutional quality, estimation methods, and controls for endogeneity. Overall, the evidence suggests that institutional quality may play a significant role in explaining sovereign CDS spreads.     

Sovereign default, interest rates and political uncertainty in emerging markets

A large body of the empirical literature shows that high turnover rates/length of tenure of policymakers and the degree of conflict within a country affects sovereign spreads, debt and default rates. We help to rationalize such claims by including these political features in a dynamic stochastic small open economy model of sovereign debt and default. In this way we offer a complementary approach to the econometric analyses in the literature. Consistent with the data, the quantitative analysis shows that politically unstable and more polarized economies experience higher default rates and larger level and volatility of sovereign interest rate spreads.     

Modeling recovery rates of corporate defaulted bonds in developed and developing countries

This paper examines the determinants of recovery rates of corporate defaulted bonds in the emerging markets. We use data on defaulted bonds from Moody's ultimate recovery database over the period 2005–2015 to experiment the impact of the borrower characteristics added to the macroeconomic and the bond market conditions on recovery rates. We find evidence that bond recovery rates in emerging and developed countries do not depend on the same factors. Our results show that bond recovery rates in developing countries seem to depend much more on specific characteristics of firms. The financial crisis has affected more significantly subordinated bond recovery rates than secured bonds in emerging markets.
