The political determinants of sovereign bond yield spreads

This paper analyzes the political determinants of sovereign bond yield spreads using data for 27 emerging markets in the period 1996 to 2009. I find strong evidence that countries with parliamentary systems (as opposed to presidential regimes) and a low quality of governance face higher sovereign yield spreads, while the degree of democracy and elections play no significant role. A higher degree of political stability and the power to implement austerity measures significantly reduce sovereign yield spreads particularly in autocratic regimes, while no significant effect is detected for democratic countries. Overall, political determinants have a more pronounced impact on sovereign bond yield spreads in autocratic and closed regimes than in democratic and open countries.     

On the determinants of yield spreads between mortgage pass-through and Treasury securities

Yield spreads between mortgage pass-through and U.S. Treasury securities may reflect differences in taxation, phenomena affecting relative supply and demand, and compensation for default, call, and marketability risks on mortgage instruments. Our research empirically models differences in yields between pass-throughs and comparable-maturity Treasuries. We find that interest-rate volatility and the term structure of rates, factors often cited in the mortgage pricing literature as affecting the mortgage call premium, are the primary determinants of movements in these spreads. Moreover, these effects have grown in importance in recent years as exercise of the prepayment option has increased. We also find evidence that liquidity and credit concerns affect the pricing of pass-through securities.

A macro-financial analysis of the euro area sovereign bond market

We estimate the ‘fundamental’ component of euro area sovereign bond yield spreads, i.e. the part of bond spreads that can be justified by country-specific economic factors, euro area economic fundamentals, and international influences. The yield spread decomposition is achieved using a multi-market, no-arbitrage affine term structure model with a unique pricing kernel. More specifically, we use the canonical representation proposed by Joslin et al. (2011) and introduce next to standard spanned factors a set of unspanned macro factors, as in Joslin et al. (forthcoming). The model is applied to yield curve data from Belgium, France, Germany, Italy, and Spain over the period 2005–2013. Overall, our results show that economic fundamentals are the dominant drivers behind sovereign bond spreads. Nevertheless, shocks unrelated to the fundamental component of the spread have played an important role in the dynamics of bond spreads since the intensification of the sovereign debt crisis in the summer of 2011.     

Individual stock-option prices and credit spreads

This paper introduces measures of volatility and jump risk that are based on individual stock options to explain credit spreads on corporate bonds. Implied volatilities of individual options are shown to contain useful information for credit spreads and improve on historical volatilities when explaining the cross-sectional and time-series variation in a panel of corporate bond spreads. Both the level of individual implied volatilities and (to a lesser extent) the implied-volatility skew matter for credit spreads. Detailed principal component analysis shows that a large part of the time-series variation in credit spreads can be explained in this way.     

Volatility in the federal funds market and money market spreads during the financial crisis

We analyze the role of federal funds rate volatility in affecting risk premium as measured by various money market spreads during the 2007–2009 financial crisis. We find that volatility in the federal funds market contributed to elevated Overnight Index Swap (OIS) spreads of unsecured bank funding rates during the crisis. Using OIS as a proxy for market expectations, we also decompose London Inter-Bank Offered Rate (Libor) into its permanent and transitory components in a dynamic factor framework and show that increased volatility in the federal funds market contributed to substantial transitory movements of Libor away from its long-run trend during the financial crisis.     

Time varying contagion in EMU government bond spreads

We analyze the time varying behavior of pure contagion effects between Economic and Monetary Union (EMU) government bond spreads before and during the subprime mortgage crisis and the EMU debt crisis. By conducting a rolling window analysis, we are able to monitor the evolution of pure contagion effects and the changing influence of exogenous factors over time. Importantly, this is done without an ex-ante specification of the contagion window. Hence, we are able to determine the exact timing of the start and end for the different contagion periods. In contrast to related studies, we use a slightly different definition of contagious events and show that this approach leads to different conclusions about the progression of the EMU debt crisis. First, the main sources of pure contagion in the later phase of the EMU debt crisis appear to be Italy and Spain and not Greece, Ireland and Portugal. Furthermore, we find that substantial contagion effects among EMU government bond spreads (caused by Ireland and Portugal) already arise during the subprime mortgage crisis and not only during the EMU debt crisis, as one might expect.     

Self-fulfilling dynamics: The interactions of sovereign spreads,sovereign ratings and bank ratings during the euro financial crisis

During the euro-area financial crisis, interactions among sovereign spreads, sovereign credit ratings, and bank credit ratings appeared to have been characterized by self-generating feedback loops. To investigate the existence of feedback loops, we consider a panel of five euro-area stressed countries within a three-equation simultaneous system in which sovereign spreads, sovereign ratings and bank ratings are endogenous. We estimate the system using two approaches. First we apply GMM estimation, which allows us to calculate persistence and multiplier effects. Second, we apply a new, system time-varying-parameter technique that provides bias-free estimates. Our results show that sovereign ratings, sovereign spreads, and bank ratings strongly interacted with each other during the euro crisis, confirming strong doom-loop effects.     

Autoregressive conditional tail behavior and results on Government bond yield spreads

Previous evidence in empirical finance indicates the potential usefulness of modeling time variation particularly in the tails of speculative return distributions. Based on results from extreme value theory, the present paper proposes a fixed changepoint Pareto-type autoregressive conditional tail (ARCT) model. Regression-based parameter estimation of the unobservable time-varying tail index is carried out via classical Kalman filtering. A model application highlights the tail index dynamics for daily changes in Government bond yield spreads between the U.S. Dollar and the Euro zone.     

Internal liquidity risk in corporate bond yield spreads

The recent global financial crisis reveals the important role of internal liquidity risk in corporate credit risk. However, few existing studies investigate its effects on bond yield spreads. Panel data for the period from year 1993 through 2008 show that corporate internal liquidity risk significantly impacts bond yield spreads (and changes) when controlling for well-known bond yield determinant variables, traditional accounting measures of corporate debt servicing ability, cash flow volatility, credit ratings, and state variables. This finding indicates that internal liquidity risk should therefore be incorporated into bond yield spread modeling.     

Trading and liquidity in the catastrophe bond market

We provide first insights into secondary market trading, liquidity determinants, and the liquidity premium of catastrophe bonds. Based on transaction data from TRACE (Trade Reporting and Compliance Engine), we find that cat bonds are traded less frequently during the hurricane season and more often close to maturity. Trading activity indicates that the market is dominated by brokers without a proprietary inventory. Liquidity is high in periods of high trading activity in the overall market and for bonds with low default risk or close to maturity, which results from lower order processing costs. Finally, using realized bid–ask spreads as a liquidity measure, we find that on average, 21% of the observable yield spread on the cat bond market is attributable to the liquidity premium, with a magnitude of up to 141 bps for high-risk bonds.     

Corporate bond liquidity and yield spreads: A review

Secondary market illiquidity is an important non-default factor affecting yield spreads. Yet, a review of the literature suggests the findings are mixed, both regarding the relative size of the default versus non-default components as well as the relative importance of liquidity premium for investment-grade and high-yield bonds. While in theory country and currency risk might affect international bonds' yield spreads, empirical findings show that international corporate bonds pricing and liquidity are generally affected by the same factors as the U.S. market. We identify several other areas of disagreement and challenges in the literature that warrant further research.     

Cross-acceleration and the relationship between board independence and bond yield spreads

This paper investigates the mediating effect of cross-acceleration provisions in bond debt on board independence and bond yield spreads. Cross-acceleration provisions cause bond debt to accelerate if other debt (mainly bank debt) is accelerated and allows bondholders to benefit from the monitoring of fellow creditors. Board independence, while generally seen as a positive governance feature, has been viewed as detrimental to bondholder interests when bondholder-shareholder conflicts are high. Cross-acceleration works to protect bondholder interests through increased likelihood of bankruptcy court supervision (or early repayment of debt). Consistent with this view, we find that when bondholder-shareholder conflict are high bonds issued without cross-acceleration provisions have yields that increase in board independence whereas bonds issued with cross-acceleration have yields that decrease in board independence. The results suggest that cross-acceleration plays a role in mitigating the tendency of more independent boards to favor shareholders when bondholder-shareholder conflicts arise.     

Government contracts and US bond yield spreads: A study on costs and benefits of materialized political connections

In a 1991–2013 sample of bonds issued by US public firms, we find that the cost of debt (yield spread relative to comparable Treasuries) of suppliers to government agencies is contingent on the strategic importance of the supplier's industry. The yield spreads for strategically unimportant government suppliers are higher than for firms that are not government suppliers. If government contracts serve as tangible evidence of political connections, these higher yield spreads indicate that weaker corporate governance as a cost of political connections outweighs the benefits of said connections. For the subsample of government suppliers from strategically important industries, where the benefits of implicit bailout guarantees and revenue stability outweigh the corporate governance problems, the cost of debt is lower than for firms that are not government suppliers. The higher (lower) cost of debt for strategically unimportant (strategically important) suppliers is confined to contracting with the federal government. Our findings are robust to alternative variable and sample specifications, and to endogeneity concerns.     

Information uncertainty,information asymmetry and corporate bond yield spreads

This study examines the effects of information uncertainty and information asymmetry on corporate bond yield spreads using American data from 2001 to 2006. Empirical results of this study show that investors charge a significant risk premium for both information uncertainty and information asymmetry when controlling for variables well known in the literature. The results are robust even when controlling for credit ratings. Finally, information uncertainty and asymmetry help structural-form credit models explain the yield spreads of bonds with short maturities.     

Yield spreads,agency costs and the corporate bond call feature

This paper theoretically compares yields and optimal default policies for callable and non-callable corporate debt. It shows that, contrary to the conventional wisdom, it is possible for the yield spread (callable minus non-callable) to be negative. It also identifies the key determinants of the yield spread. Next, it shows that the optimal default trigger for non-callable debt is higher than the trigger for callable debt, resulting in additional default-related costs. Thus, the use of non-callable debt gives rise to an indirect agency cost of early default, which is the difference in total firm value with callable and non-callable debt. This agency cost provides a rationale for the existence of callable debt. By examining the determinants of the magnitude of this agency cost, the conditions that make callable debt more attractive (to the issuing firm) relative to non-callable debt are identified. This allows certain predictions to be made regarding the likelihood of a call feature in a corporate bond. The model's implications are supported by existing empirical studies.     

Suppliers’ and customers’ information asymmetry and corporate bond yield spreads

This study investigates the information asymmetry effects of suppliers and customers on a firm’s bond yield spreads by employing American bond market data from 2001 to 2008. This study finds that both suppliers’ and customers’ information asymmetry effects significantly explain a firm’s bond yield spreads. Besides, the information asymmetry effects of more important suppliers and customers are more significant than those of less important ones. The results are robust even after controlling for other well-known firm specific and economic variables.     

Bank capital shortfall in the euro area

We quantify the bank capital shortfall that results from a financial crisis by estimating a macro-finance dynamic stochastic general equilibrium model that captures the interactions between the financial and real sectors of the euro-area economy. The introduction of both deposit and shadow banks captures several characteristics of the banking system and reveals a financial amplification mechanism. By using a combination of a large positive risk shock and a large negative investment shock, we show that a crisis similar to that observed in 2008 would generate a bank capital shortfall between 2.2% and 3% of euro-area GDP, which corresponds to approximately 207–282 billion euros.     

Macro news and stock returns in the Euro area: A VAR-GARCH-in-mean analysis

This paper analyses the effects of newspaper coverage of macro news on stock returns in eight countries belonging to the euro area (Belgium, France, Germany, Greece, Ireland, Italy, Portugal and Spain) using daily data for the period 1994–2013. The econometric analysis is based on the estimation of a VAR-GARCH-in-mean model. The results can be summarised as follows. Positive (negative) news have significant positive (negative) effects on stock returns in all cases. Their volatility has a significant impact on both stock returns and volatility; specifically, an increase in news volatility is always associated with a decrease in stock returns. Markets are particularly responsive to negative news, and the reaction is bigger in the PIIGS countries, and during the recent crisis period.     

The impact of economic news on bond prices: Evidence from the MTS platform

Although there is an extensive literature on the impact of macroeconomic announcements on asset prices, the bond market has received less attention than the foreign exchange and equity markets, even less if we consider the European market. This paper uses high-frequency intra-day data over a three-year period to investigate the impact of regularly scheduled macroeconomic news and monetary policy announcements on the returns of the Italian government bond market, the largest one in the Euro-zone. With respect to the previous papers, we use a much broader set of announcements, 68, and a relatively novel dataset (MTS). We find that 25 news have a significant impact on bond returns and that almost all announcements are incorporated into prices within 20 min from the release.
