Corporate Credit Spreads and the Sovereign Ceiling in Latin America

We exploit a panel of 72 US dollar-denominated bonds issued by Latin American publicly listed firms between 1996 and 2004, a period of regional financial crises, to answer the following three questions: (1) Is sovereign risk a statistically and economically significant determinant of the corporate credit spread, controlling for firm- and bond-specific characteristics? (2) If yes, do market participants apply the sovereign ceiling rule adopted by rating agencies in the pricing of our bond market data? And (3) how do market views compare with the rating agencies ceiling policy for each corporate bond? We find strong evidence of an economically and statistically significant effect of sovereign risk on corporate spreads across different panel econometric specifications and bonds. Moreover, markets do not apply the ceiling rule in 77–90% of the bonds we sample and these findings are consistent with rating agencies’ policies toward the latter for about 50% of the firms. These results are robust to the inclusion of firm- and bond-specific variables derived from the structural approach to credit risk and to the business cycle in each country.     

Determinants of sovereign yield spreads in the Eurozone: A Bayesian approach

We analyze the determinants of sovereign yields spreads of EMU member states applying Bayesian Model Averaging (BMA) to annual panel data from 1999 to 2009. BMA is well-suited in cases of small samples and high model uncertainty. This seems to be the case in modeling sovereign yield spreads in the Eurozone since the literature reports heterogeneous results with respect to significant explanatory variables. We are testing a number of variables reported to be significant in the literature and find that the most likely country specific drivers of yield spreads are fiscal variables such as budget balance and government debt, as well as external sector variables, such as terms of trade, trade balance and openness. Global financing conditions, indicated by the US interest rate, and market sentiments, indicated by corporate bond spreads, are likely to influence sovereign yield spreads.     

Emerging market bond returns—An investor perspective

The novel features of this study consist in applying a conventional multifactor global market model to emerging market sovereign bond index rates of return that are denominated in US dollars and subsequently relating the unexplained residuals from the market model's estimates of each country's total bond index return to country-specific factors. They include political and financial risks as well as other presumed determinants of bond index rates of return. The results of our study confirm that sovereign countries’ bond index rates of return that include interest payments and capital gains/losses may be explained in terms of conventional bond pricing models by combining global market factors with local risk and other country-specific influences.     

Fragmentation and heterogeneity in the euro-area corporate bond market: Back to normal?

We assess the degree of market fragmentation in the euro-area corporate bond market by disentangling the determinants of the risk premium paid on bonds at origination. By looking at over 2400 bonds we are able to isolate the country-specific effects which are a suitable indicator of the market fragmentation. We find that, after peaking during the sovereign debt crisis, fragmentation shrank in 2013 and receded to pre-crisis levels only in 2014. However, the low level of estimated market fragmentation is coupled with a still high heterogeneity in actual bond yields, challenging the consistency of the new equilibrium.     

Expectations and systemic risk in EMU government bond spreads

This paper explores the determinants of 10-year sovereign bond spreads over the German Bund benchmark in the Euro Zone from 2000 to 2013, relying on cross-country quarterly data panel analysis. The paper focal point is the role of contagion and euro break-up risks in widening the sovereign bond yield differentials among EU member countries. Using a novel synthetic index capable of monitoring the sustainability of currency unions, the paper finds that market expectations of a euro’s break up and contagion from Greece were fundamental drivers of sovereign risk premia in peripheral countries.     

Macroeconomic imbalances,financial stress and fiscal vulnerability in the euro area before the debt crises: A market view

This paper tries to identify the macro-financial imbalances that exposed the euro area countries to fiscal stress before the outbreak of the European debt crises. Contrary to conventional wisdom that interprets fiscal stress in terms of fiscal sustainability, we focus on short-term fiscal vulnerability as reflected by the conditions of debt refinancing in the sovereign bond markets. We find that market-based indicators capturing risk perceptions of sovereign debts have been influenced by the indicators defined in the European Macroeconomic Imbalance Procedure (MIP) and by variables of financial vulnerability. When pricing the risk of sovereign bonds, the holders of government debts take into account not only the macroeconomic imbalances but also factors such as banking distress, corporate bond risk, liquidity risks in the interbank market or the volatility of stock prices.     

The effect of social screening on bond mutual fund performance

This study measures the financial impact of screening for environmental, social and governance criteria on corporate bond portfolios. Specifically, the risk-adjusted financial performance of 103 socially responsible bond funds in the US and the Eurozone is compared with a matched sample of conventional funds. During the period 2001–2014, socially responsible bond funds outperform by one-half of one percent annually. An evaluation of fund holdings and a performance-attribution analysis suggest that this outperformance is directly related to the mitigation of ESG risks, which is achieved by the exclusion of corporate bond issuers with poor corporate social responsibility activities. A separation of crisis and non-crisis periods further indicates that the outperformance is especially likely to occur during recessions or bear market periods. We confirm this crisis-related return effect from a sample of socially screened bond indices. Moreover, our results are robust to alternative definitions of sustainability, survivorship bias, fund characteristics and stable in the US and Eurozone sub-samples.     

Credit default swaps and the market for sovereign debt

In this paper, we analyze the determinants and effects of credit default swap (CDS) trading initiation in the sovereign bond market. CDS trading initiation is associated with a 30–150 basis point reduction in sovereign bond yields, with greater yield reductions accruing to higher default risk economies. For countries with high default risk, rated B or lower by Standard and Poor’s, CDS initiation is also associated with significant price efficiency benefits in the underlying market. CDS trading initiation is more likely following increases in local equity index volatility, index spreads for regional and global CDS markets, or depreciation of the local currency relative to the US dollar, and decreases in a country’s ability to service foreign debt. Our results are robust to selection bias controls based on these factors.     

Performance aspects of Greek bond mutual funds

This paper examines the performance characteristics of Greek bond funds and the impact of fund flows on portfolio returns. The evidence shows that on average bond funds do not offer risk-adjusted profits exceeding the returns of the benchmark index, which is in consistence with the US and international evidence. Returns before fees are slightly superior to the returns of the benchmark index, but when fees are considered they lag considerably. The security selection and market timing skills of fund managers are also tested using both an unconditional and a conditional model to test for the impact of public information variables. We also find that fund flows impact negatively on market timing.     

Sovereign debt risk in emerging market economies: Does inflation targeting adoption make any difference?

Based on a sample of 38 emerging economies, we find that inflation targeting (IT) adoption improves sovereign debt risk. Next, we show that this favorable effect is sensitive to several structural characteristics, and to the considered time span. Finally, the measure of sovereign risk (sovereign debt ratings or government bond yield spreads) and the IT form (full-fledged or partial) equally influence the effect of IT adoption on sovereign debt risk. Thus, our paper provides valuable insights regarding IT implementation as a device for improving emerging market economies' access to international financial markets.     

Exploring the market risk profiles of US and European stock insurers

Market risks account for an integral part of insurers' risk profiles. We explore market risk sensitivities of insurers in the United States and Europe. Based on panel regression models and daily market data from 2012 to 2018, we find that sensitivities are particularly driven by insurers' product portfolio. The influence of interest rate movements on stock returns is 60% larger for US than for European life insurers. For the former, interest rate risk is a dominant market risk with an effect that is five times larger than through corporate credit risk. For European life insurers, the sensitivity to interest rate changes is only 44% larger than toward credit default swap of government bonds, underlining the relevance of sovereign credit risk.

Has the CDS market influenced the borrowing cost of European countries during the sovereign crisis?

This paper assesses the potential influence of the growing CDS market on the borrowing cost of sovereign states during the European sovereign crisis. We analyze the sovereign debt market to ascertain the pattern of information transmission between the CDS and corresponding bond markets. Our methodological innovation is the use of a non-linear specification rather than the linear VECM specification customarily employed. Using a panel smooth transition model during the 2008–2010 period, we find that: 1) linearity tests clearly reject the null hypothesis of a linear transmission mechanisms between the bond and the CDS markets; 2) market distress alters the mutual influence and 3) the higher the distress the more the CDS market dominates the information transmission between CDS and bond markets.     

News and the cross-section of expected corporate bond returns

We study the cross-section of expected corporate bond returns using an inter-temporal CAPM (ICAPM) with three-factors: innovations in future excess bond returns, future real interest rates and future expected inflation. Our test assets are a broad range of corporate bond market index portfolios. We find that two factors – innovations about future inflation and innovations about future real interest rates – explain the cross-section of expected corporate bond returns in our sample. Our model provides an alternative to the ad hoc risk factor models used, for example, in evaluating the performance of bond mutual funds.

Corporate Restructuring and Bondholder Wealth

This paper provides an overview of existing research on how corporate restructuring affects bondholder wealth. Restructuring is defined as any transaction which affects the firm's riskiness by changing its underlying capital structure. Thus, it reaches well beyond asset restructuring and includes transactions such as leveraged buyouts, security issues and exchanges, and the issuance of stock options. We identify significant gaps in the literature, emphasize the potential differences in bond performance between market‐ and stakeholder‐oriented corporate governance systems, and provide valuable insights into methodological advances. We find that many issues remain as the empirical evidence is often inconclusive and focuses almost exclusively on the US. Research on other countries remains constrained by the lesser development of their bond markets, but is equally imperative because the position and bargaining power of creditors vis‐à‐vis the firm differ substantially across countries and governance regimes.     

The network structure of the CDS market and its determinants

This paper analyses the network structure of the credit default swap (CDS) market and its determinants, using a unique dataset of bilateral notional exposures on 642 financial and sovereign reference entities. We find that the CDS network is centred around 14 major dealers, exhibits a “small world” structure and a scale-free degree distribution. A large share of investors are net CDS buyers, implying that total credit risk exposure is fairly concentrated. Consistent with the theoretical literature on the use of CDS, the debt volume outstanding and its structure (maturity and collateralization), the CDS spread volatility and market beta, as well as the type (sovereign/financial) of the underlying bond are statistically significantly related—with expected signs—to structural characteristics of the CDS market.     

On the exposure of insurance companies to sovereign risk—Portfolio investments and market forces

A sovereign debt crisis can have significant knock-on effects in the financial markets and put financial stability at risk. This paper focuses on the transmission of sovereign risk to insurance companies as some of the largest institutional investors in the sovereign bond market. We use a firm level panel dataset that covers large insurance companies, banks and non-financial firms from nine countries over the time period from 1 January 2008–1 May 2013. We find significant and robust transmission effects from sovereign risk to domestic insurers. The impact on insurers is not significantly different from that on banks but larger than for non-financial firms. We find that systemically important insurers are more closely linked to the domestic sovereign. Based on European data, we show that risks in sovereign bond portfolios are an important driver of insurer risk, which is not reflected in current insurance regulation (incl. Solvency II in Europe).     

Illiquidity or credit deterioration: A study of liquidity in the US corporate bond market during financial crises

We investigate whether liquidity is an important price factor in the US corporate bond market. In particular, we focus on whether liquidity effects are more pronounced in periods of financial crises, especially for bonds with high credit risk, using a unique data set covering more than 20,000 bonds, between October 2004 and December 2008. We employ a wide range of liquidity measures and find that liquidity effects account for approximately 14% of the explained market-wide corporate yield spread changes. We conclude that the economic impact of the liquidity measures is significantly larger in periods of crisis, and for speculative grade bonds.     

Macroeconomic effects of corporate default crisis: A long-term perspective

Using an extensive data set on corporate bond defaults in the US from 1866 to 2010, we study the macroeconomic effects of bond market crises and contrast them with those resulting from banking crises. During the past 150 years, the US has experienced many severe corporate default crises in which 20–50% of all corporate bonds defaulted. Although the total par amount of corporate bonds has at times rivaled the amount of bank loans outstanding, we find that corporate default crises have far fewer real effects than do banking crises. These results provide empirical support for current theories that emphasize the unique role that banks and the credit and collateral channels play in amplifying macroeconomic shocks.
