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.     

Immunity and infection: Emerging and developed market sovereign spreads over the Global Financial Crisis

We compare sovereign bond spreads during the international financial crisis across groups drawn from 43 countries, including 20 emerging economies. We extend traditional factor analyses and utilize propensity score matching to select a non-crisis sample for comparison with the crisis sample that is more robust to exogenous crisis dating. We find minimal changes over the crisis period in the average spreads of local-currency-denominated emerging market bonds. In contrast, the spreads of peripheral Eurozone sovereign bonds increased by large amounts and were subject to sovereign risk contagion.     

On the stability of domestic financial market linkages in the presence of time-varying volatility

We analyze the stability of domestic financial linkages between periods of calm and turbulent market conditions. Our model develops a simultaneous test of shift contagion and bi-directional pure contagion, which is applied to the equity and currency markets of a group of East Asian emerging economies. Our results show a great deal of instability in these markets with widespread evidence of pure contagion in both directions. There is less evidence of shift contagion with the transmission of common shocks unchanged between regimes for the majority of countries.     

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.     

What explains default risk premium during the financial crisis? Evidence from Japan

As is well documented, subprime mortgage markets carried significant default risk. This paper investigates the relationship between default risk premium, stock market conditions and macroeconomic variables during the financial crisis. Using iTraxx Japan Credit Default Swap (CDS) index spreads covering the period from March 2006 to November 2009, we employ a time-varying dynamic factor model with Markov regime switching to generate regime probabilities for default risk. We analyze the sensitivity of default risk premium changes to stock market conditions and macroeconomic variables by using two-state Markov switching models: a crisis regime sparked by rising loan defaults in the sub-prime mortgage market, and a non-crisis regime. We found strong evidence that the relationship between default risk premium changes, stock market and macroeconomic variables is regime-dependent. Our results suggest that during periods of crisis, CDS indices behave as a higher-risk indicator and become more sensitive to stock market conditions and macroeconomic variables. This paper examines the effects of the financial crisis in explaining the default risk premium. Understanding the determinants of default risk premium is important for financial analysts, economic policy makers and credit risk management.     

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.     

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.’     

Mexican peso crisis and its spillover effects to emerging market debt

This paper examines the spillover effects of the Mexican financial crisis to emerging financial markets. As of November 1994, the financial markets were not anticipating a change in exchange rate regime in Mexico. Coincident with the peso devaluation on 20, December 1994, Mexican Brady bond prices declined significantly and continued to experience significant decline during the subsequent three months. Emerging market assets reacted differently to the Mexican crisis. Latin America as a region was more exposed to the Mexican crisis than emerging markets from other regions. The ratio of liquid monetary assets to international reserves and the ratio of current account to GDP were the most influential variables in explaining variation in CARs across countries. Trade competition with third markets was the most significant transmission channel during the Mexican crisis.     

Bond yields in emerging economies: It matters what state you are in

While many studies have looked into the determinants of yields on externally issued sovereign bonds of emerging economies, analysis of domestically issued bonds has hitherto been limited, despite their growing relevance. This paper finds that the extent to which fiscal variables affect domestic bond yields in emerging economies depends on the level of global risk aversion. During tranquil times in global markets, fiscal variables do not seem to be a significant determinant of domestic bond yields in emerging economies. However, when market participants are on edge, they pay more attention to country-specific fiscal fundamentals, revealing greater alertness about default risk.     

Understanding the sovereign credit ratings of emerging markets

This paper identifies the macroeconomic factors behind the sovereign credit ratings of global emerging markets assigned by Standard and Poor's (S&P). The financial integration and globalization of capital markets have facilitated the capital inflows/outflows among countries. Sovereign credit ratings have served as a signal for countries' economic, financial and political situations. Ratings are very important in the sense that they attract capital inflow and investments. This is especially vital for emerging markets. Although the rating agencies do not explicitly reveal their methodologies, it is possible to guess the effects of several variables on ratings by using various econometric models. Concerning the heavy criticisms on rating agencies' performances, we wish to examine the sovereign credit ratings within a specific country-category. In this essay, we study the effects of macroeconomic factors on the sovereign ratings of emerging markets. Using several approaches, we find that the most relevant factors are Budget Balance/GDP, GDP per capita, Governance Indicators and Reserves/GDP. Moreover, our model predicts up to 93% of all credit rating levels. Interestingly, we obtain that S&P's evaluation of the sovereign credit rating for Turkey performs poorly, especially in the highest rating levels.     

Financial market development in host and source countries and their effects on bilateral foreign direct investment

We study an underexplored research question, namely whether financial market development in both host and source countries has an effect on bilateral stocks of foreign direct investment (FDI) and, particularly, whether the effect of financial market development in one member of the country pair conditions the effect of financial market development in the other member. We estimate gravity-type models in a global sample of 43 source and 137 host countries over the period 2001–12. We address reverse causality concerns by restricting the sample to observations where reverse causality, if existent, should be less relevant. Our major and robust findings are that bilateral FDI increases with better developed financial markets in both the host and the source country and that for developing host countries, financial market development in source and host countries functions as substitutes for each other.     

The anatomy of financial crises: Evidence from the emerging ADR market

We study the anatomy of recent financial crises in Mexico, East Asia, Russia, Brazil, Turkey, and Argentina by investigating the efficiency and pricing of the emerging American depositary receipt (ADR) market. We use a non-parametric technique to test for persistent regime shifts in two basic structural relationships for ADR returns in 20 emerging countries — identified via arbitrage and capital mobility considerations — that should always hold in efficient and integrated capital markets. We find that those “normal” market conditions were instead often violated in proximity of financial crises: The law of one price often weakened (by 54% on average) and domestic sources of risk became more important (often by more than 100%) for many emerging ADRs. We also find the likelihood of these regime shifts to be related to proxies for uncertainty among investors, exchange rate volatility, trade linkages, and liquidity (but not stock market trends, currency devaluations, capital flight, or capital controls).     

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.

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.     

Sovereign credit ratings,capital flows and financial sector development in emerging markets

How does the sovereign credit ratings history provided by independent ratings agencies affect domestic financial sector development and international capital inflows to emerging countries? We address this question utilizing a comprehensive dataset of sovereign credit ratings from Standard and Poor's from 1995–2003 for a cross-section of 51 emerging markets. Within a panel data estimation framework, we examine financial sector development and the influence of sovereign credit ratings provision, controlling for various economic and corporate governance factors identified in the financial development literature. We find strong evidence that our sovereign credit rating measures do affect financial intermediary sector developments and capital flows. We find that i) long-term foreign currency sovereign credit ratings are important for encouraging financial intermediary development and for attracting capital flows. ii) Long-term local currency ratings stimulate domestic market growth but discourage international capital flows. iii) Short-term ratings (both foreign and local currency denominated) retard all forms of financial developments and capital flows. There are important implications in this research for policy makers to encourage the provision of longer-term credit ratings to promote financial development in emerging economies.     

Diversification potential of Asian frontier,BRIC emerging and major developed stock markets: A wavelet-based value at risk approach

This study examines the portfolio risk and the co-movements between each of the BRIC emerging and South Asian frontier stock markets and each of the major developed stock markets (U.S., UK and Japan), using the wavelet squared coherence approach as well as the wavelet-based Value at Risk (VaR) method. The results show that the co-movements and diversification benefits between these markets vary over time and across frequencies. Additionally, the co-movements are intensified in the wake of the recent global financial crisis (GFC) and the Eurozone sovereign debt crisis (ESDC). More precisely, the wavelet-based VaR ratio indicates that including a BRIC or a South Asian (particularly Pakistan and Sri Lanka at both the short- and long-term) stock market in a portfolio of the developed stock markets reduces the resulting portfolio's VaR. Specifically, adding China in the medium term to this portfolio reduces risk in the pre- and during both the GFC and ESDC periods. By assigning optimal weights to the different market assets in the portfolio formulation, the analysis thus has implications for international investors.     

Herding behaviour in an emerging market: Evidence from the Moscow Exchange

This study investigates the extent to which herding towards the market consensus for Russian stocks is driven by fundamental and non-fundamental factors. We find evidence that investors on the Moscow Exchange herd without any reference to fundamentals during unanticipated financial crises coupled with high uncertainty, in falling markets, and during days with extreme upward oil price movements. In contrast, in periods of high liquidity and on days of international sanction announcements during the Ukrainian crisis, herding behaviour is merely driven by fundamentals. In Russia, macroeconomic news releases induce both information-related herding and herding without any reference to fundamentals. These results suggest that motives of investors' herding behaviour vary under specific market conditions such as market trends, liquidity, uncertainty, arrival of new information, and oil price volatility.     

Institutional determinants of emerging market returns and flows

Investors commonly rely on macroeconomic variables to drive capital allocation decisions. But other institutional factors may alter investor returns as well, particularly in emerging market countries. Given these concerns, this paper examines the effects of institutional factors—specifically democracy, transparency and corruption—on emerging market equity returns and flows. We find that institutional quality impacts stock market returns and flows in emerging markets where corruption, transparency, and democracy levels are below average. We also find that government-owned or controlled industries are positively impacted by a deterioration in the corruption and democracy indexes, while highly concentrated sectors, like the financial industry, are negatively impacted by improving transparency.     

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.
