The sovereign spread in Asian emerging economies: The significance of external versus internal factors

This paper investigates the dynamic relations between external factors, domestic macroeconomic factors with sovereign spreads, debt to GDP ratio, etc. in Asian emerging countries. First, we develop a theoretical model that determines the equilibrium debt level, probability of default and sovereign spread and draw empirical implications. We then employ a Structural Vector Autoregression (SVAR) model to investigate empirically how the spread of sovereign debt is influenced over time by both external and domestic factors. The empirical results show that variations in sovereign spreads are mainly driven by external shocks, with the term structure of US interest rate and the global risk aversion having the most important role. The findings also indicate that shocks from the US have a direct effect on sovereign spread and an indirect effect via domestic macroeconomic fundamentals. Finally, the evidence produced validates the presence of some response patterns of sovereign spread to the external shocks.     

Modelling country default risk as a latent variable: a multiple indicators multiple causes approach

We study the determinants of country default risk by applying a Multiple Indicators Multiple Causes (MIMIC) model. This accounts for the fact that country default risk is an unobservable variable. Whereas existing (regression-based) approaches typically use only one of several possible country default risk indicators as the dependent variable, the MIMIC model enables us to consider several indicators at once. The simultaneous consideration of sovereign yield spreads and Standard and Poor (S&P) ratings may help to improve the identification of the latent country default risk. Our results confirm most of the literature's main findings regarding important determinants of country default risk, refute others and provide new evidence to controversial questions.     

HETEROGENEOUS BORROWERS IN QUANTITATIVE MODELS OF SOVEREIGN DEFAULT*

We extend the model used in recent quantitative studies of sovereign default, allowing policymakers of different types to stochastically alternate in power. We show that a default episode may be triggered by a change in the type of policymaker in office, and that such a default is likely to occur only if there is enough political stability and if policymakers encounter poor economic conditions. Under high political stability, political turnover enables the model to generate a weaker correlation between economic conditions and default decisions, a higher and more volatile spread, and lower borrowing levels after a default episode.     

Increase in home bias in the Eurozone debt crisis: The role of domestic shocks

One of the most striking consequences of the recent episode of sovereign debt market stress in the Eurozone has been the increase in the share of public debt held by the domestic sector in fragile economies. However, the causes and potential consequences of this increase were only given scarce attention in the literature on the Euro area sovereign debt crisis. In order to fill this gap, we first determine the shocks that impact the variation in the share of sovereign debt held at home in an SVAR model on a sample of Eurozone countries between 2002 and 2014, distinguishing between external and domestic shocks. Thanks to several alternative tests, we show that home bias in sovereign debt responds positively to country-specific fundamentals and expectation shocks but we find no evidence that the increase in home bias is destabilizing per se in the short-run. Second, a stylized theoretical model backed by the empirical results predicts that the consequences for sovereign debt crisis depend on the relative impact of domestic initial destabilizing shocks and increased home bias. The analysis suggests that an increase in home bias in times of sovereign debt stress, despite reflecting deteriorating fiscal conditions, may make default less likely.     

Testing for Regime Changes in Greek Sovereign Debt Crisis

This paper examines whether the efficiency market hypothesis for the Greek sovereign debt holds. As in Blanco et al. (2005) we test the theoretical equivalence of credit default swap (CDS) and spreads that dictates a CI relationship between the two. The main innovation of the present analysis is the use of a threshold vector error-correction (TVECM) model, thus allowing thresholds within the sample covering the period 1990 to 2010. Moreover, by employing this methodology we are able to evaluate the degree and dynamics of transaction costs resulting from various events due to external market imperfections but also domestic factors. The main hypothesis we test is to what extent spreads and CDS are indeed integrated that may result in an efficient and integrated segniorage capital market. Our findings support the gradual integration hypothesis. We find that spreads and CDS are cointegrated, though threshold effects are also revealed in terms of events that have impacted on markets.     

Risks of Latin America sovereign debts before and after the financial crisis

We investigate the financial determinants of the return and volatility of sovereign CDS spread from six major Latin American countries before and after the bankruptcy of Lehman Brothers. Other than CBOE VIX index, we also find that global factors including US Baa–Aaa default yield, TED spread and US Treasury rate all contribute to the changes in these sovereign CDS spread. Although global risk aversion (VIX) is a significant determinant of sovereign debt spread, in the years after the crisis, the emphasis has shifted towards short-term refinancing risk (TED). Furthermore, the risk of Greek sovereign debt crisis also transmitted Latin American CDS spreads immediately, but only in the post-Lehman sub-period. These findings provide implications for international bonds and credit derivatives trading strategies.     

How Information Quality of Macro Aggregates Affects Sovereign Risk: An Empirical Investigation

This paper looks at the relationship between data quality of macro aggregates and the repayment ratio for debt payments due in a given year after a country defaults. We find empirical evidence that good information of macro aggregates reduces sovereign risk by enhancing the repayment ratio conditional on default, while having an insignificant effect on the default probability. The estimation accounts for selection bias by using a cross-country panel data of 69 developing countries for 1989–2002. Careful consideration is taken to establish information quality of macro aggregates as an exogenous institutional variable. Results are robust to controlling for various governance factors, income levels, and regional factors, etc. Linking information quality to creditors' bargaining power is more consistent with our findings than linking poor information quality to information asymmetry.     

The elusive costs of sovereign defaults

The evidence supporting the presence of output losses associated with sovereign defaults is based on annual observations and suffers from measurement and identification problems. This paper examines the impact of default on growth using quarterly data and finds that output contractions precede defaults and that output starts growing after the quarter in which the default took place. This indicates that default episodes mark the beginning of the economic recovery and that the negative effects of a default on output are likely to be driven by the anticipation of default, independently of whether or not the country ultimately decides to validate it.     

Sovereign debt spread and default in a model with self-fulfilling prophecies and asymmetric information

The euro area sovereign debt crisis has renewed interest in government credibility and the risk of default. Recent empirical evidence has shown that the sharp increase in government bond yields cannot be attributed entirely to changes in macroeconomic fundamentals. Contagion effects can occur, and self-fulfilling speculation may arise. In this paper, we develop a theoretical model in the spirit of the second-generation currency crisis models developed by Obstfled (1996). The model describes a strategic game between governments and private investors. Euro area countries face a trade-off as governments may either commit to and implement restrictive fiscal policies or default on debt. The commitment strategy may not be optimal if the fundamentals deteriorate. The policy maker lose part of their credibility, and governments are forced to default. In addition, we introduce uncertainty about the cost of default in the model, which is then able to account for a greater variety of equilibrium. Thus, when the evaluation of the cost of default is asymmetric, prophecies are not always realized and default does not occur. Simulations of the model then show that it offers insights, and can help to account for the situations of Greece and Italy during the sovereign debt crisis.     

Country factors and the investment decision-making process of sovereign wealth funds

In this paper, we examine the complex decision-making processes that lead to sovereign wealth funds' (SWFs’) choice of investment location. Using a two-tiered dynamic Tobit panel model, we find that country-level factors do not have the same impacts on the investment decision and the amount to invest and that SWFs tend to invest more frequently and at higher amounts in countries in which they have already invested. More specifically, we find that SWFs prefer to invest in countries with higher political stability, whereas they are more prone to invest large amounts in countries that are less democratic and more financially open. Our results also lend support to the idea that SWFs are prudent in their choice of a target country with regard to their investment decision but behave as more opportunistic investors with regard to the amounts to be invested.     

Domestic versus External Borrowing and Fiscal Policy in Emerging Markets

This paper presents a model of an emerging market sovereign that can selectively default on its domestic or external creditors. The two classes of creditors have different ways of punishing the government in the event of default, which in turn creates a differential in the sovereign's incentives to default on its domestic versus foreign creditors. We explore the extent to which the possibility of differential treatment of creditors affects the composition of debt. We find that a country characterized by volatile output, sovereign risk, and costly tax collection will want to borrow in domestic as well as in international markets.     

Sovereign bond markets with political risk and moral hazard

A model of interest rates on sovereign bonds with default risk is presented. The model accounts for interaction between interest rates and default risk. Multiple equilibria and stability issues are examined. The model explores the level of debt that markets will tolerate in a context where there is uncertainty about output growth, fiscal discipline, real exchange rates, and IMF intervention. The effect of likely IMF assistance on the debt ceiling is shown to be large.     

Sovereign credit ratings,growth volatility and the global financial crisis

Using monthly data from January 1996 to May 2010 for a panel of 76 developed and emerging economies and adopting an instrumental variable (IV) estimation technique by correcting for both heterogeneity and endogeneity with the generalized two-stage least squares (G2SLS, EC2SLS) procedure method suggested by Balestra and Varadharajan-Krishnakumar (1987) and Baltagi and Li (1995), this article provides empirical evidence that volatility of per capita GDP growth is reduced when there are positive changes in credit ratings; in other words when sovereign credit risk improves. To deal with potential simultaneity between sovereign credit ratings and output volatility, a system (3SLS) approach is undertaken, and our findings remain robust. By weakening the volatility dampening effects of ratings changes, it is found that the global financial crisis (GFC) has enhanced macroeconomic volatility. One of the channels via which sovereign rating changes affect growth volatility is the financial markets’ repricing of sovereign default risk that is reflected in sovereign credit default swap (CDS) spreads and its volatility.     

Evaluating sovereign risk spillovers on domestic banks during the European debt crisis

Using a Markov-switching model with time-varying probabilities, spillovers from sovereign to domestic bank CDS spreads during the European debt crisis for a set of 14 European countries and 30 European banks are investigated. Our model is able to capture how the increased sovereign risk observed between 2010 and 2013 throughout Europe has impacted i) the probability that banks fall into a crisis regime and ii) the probability that banks stay in the crisis regime. The latter state is characterized by a high volatility and large positive returns of CDS spreads. Different regime-dependent indicators have been computed to assess heterogeneity within the region. The evidence indicates that the intensification of sovereign risk observed during the European debt crisis has positively and significantly driven the regime shifts in volatility of the bank CDS spreads due to increased risk aversion. The results show that the increase in sovereign credit risk seems to have generated second-round effects for some banks that have experienced a deterioration in their funding conditions due to a rise in the domestic sovereign default risk. Overall, our results suggest that sovereign CDS spreads can be considered good forewarning indicators for predicting the evolution of bank CDS spreads. We also find that the effects differ depending on the country and the financial institution. This result suggests that banks are heterogeneously exposed to sovereign credit risk within the same country. One argument relates to the size of these financial institutions and the domestic exposure to sovereign debt.     

Sovereign default risk and decentralization: Evidence for emerging markets

We study the impact of decentralization on sovereign default risk. Theory predicts that decentralization deteriorates fiscal discipline since subnational governments undertax/overspend, anticipating that, in the case of overindebtedness, the federal government will bail them out. We analyze whether investors account for this common pool problem by attaching higher sovereign yield spreads to more decentralized countries. Using panel data on up to 30 emerging markets in the period 1993–2008 we confirm this hypothesis. Higher levels of fiscal and political decentralization increase sovereign default risk. Moreover, higher levels of intergovernmental transfers and a larger number of veto players aggravate the common pool problem.     

Sovereign default risk and volatility

In a model of sovereign debt with endogenous default, we find a non-monotonic relationship between default risk and volatility, reflecting a trade-off between prudence and the insurance value of default. We show that this feature also holds in the data.     

Sovereign default risk and state-owned bank fragility in emerging markets: evidence from China and Russia

In this paper we investigate the interdependence of the sovereign default risk and banking system fragility in two major emerging markets, China and Russia, using credit default swaps as a proxy for default risk. Both countries’ banking industries have strong ties with their governments and public sector, even after a series of significant reforms in the last two decades. Our analysis is built on the case studies of each country’s two biggest banks. We employ a bivariate vector autoregressive (VAR) and vector error correction (VECM) framework to analyse the short- and long-run dynamics of the chosen CDS prices. We use Granger causality to describe the direction of the discovered dynamics. We find evidence of a stable long-run relationship between sovereign and bank CDS spreads in the chosen time period. The more stable relationship is found in cases where the biggest state-owned universal banks in emerging markets are closely managed by the government. But the fragility of those banks does not directly affect the state of public finances. However, in cases where state-owned banks directly participate in large governmental projects, banking fragility may result in the deterioration of state funds, while raising the risk of sovereign default.     

Macroeconomic variables and the sovereign risk premia in EMU,non-EMU EU,and developed countries

This project studies and models key macroeconomic variables and their impact on sovereign risk premia across select European economies and developed countries. The sample is divided into three groups of countries: those in the European Monetary Union (EMU); the standalone economies outside the EMU but members of the broader European Union (EU); and other developed economies. The main subject of examination across all three groups is the impact of macroeconomic variables on sovereign borrowing costs. EU countries have experienced high financial stress and a rapid rise in the credit default swaps (CDS) spreads during the EMU debt crisis. A nonlinear vector smooth transition autoregressive model is applied to investigate such a regime change in the finance-output link using sovereign CDS and industrial production index. The paper finds that regime-switching takes place rather suddenly in most EMU countries. The study concludes that due to the potential spillover effects in the EU as a whole, the individual country macroeconomic indicators were less reflected in the financial stress and spillover and contagion effects became dominant.     

Fiscal policy and default risk in emerging markets

Emerging market economies typically exhibit a procyclical fiscal policy: public expenditures rise (fall) in economic expansions (recessions), whereas tax rates rise (fall) in bad (good) times. Additionally, the business cycle of these economies is characterized by countercyclical default risk. In this paper we develop a quantitative dynamic stochastic small open economy model with incomplete markets, endogenous fiscal policy and sovereign default where public expenditures and tax rates are optimally procyclical. The model also accounts for the dynamics of other key macroeconomic variables in emerging economies.     

LEVERAGED BUYBACKS OF SOVEREIGN DEBT: A MODEL AND AN APPLICATION TO GREECE

The model presented in this article shows that the outcome of a leveraged buyback of sovereign debt depends on the priority structure of the deal. If the institution lending the funds needed for the buyback is senior, the debtor country benefits from the deal: the government debt is reduced, implying a lower probability of default; at the same time, the deal makes the price of outstanding bonds go down, since their recovery rate declines. The opposite holds if the lending institution is junior. If the loan is underpriced, the implied subsidy is shared between the borrowing country and its bondholders, who can benefit from a price increase of their bonds. This is actually what happened with the buyback of Greek sovereign bonds in 2012, as it is shown in the empirical section. Those results do not depend on the share of country's endowment devoted to debt repayment, which instead plays a crucial role in shaping the outcome of unlevered buybacks. (JEL F34, H63)
