Sovereign Bond Yield Spreads Research Articles

Anatomy of sovereign yield behaviour using textual news

While the relationship between the information content of macroeconomic news and the behavior of asset prices has been studied extensively in the finance literature, this study provides a new perspective by examining the impact of textual news on sovereign bond yield spreads in an emerging country. This study used bond market news published in newspapers to develop the sentiment scores using a modified word dictionary to unravel news characteristics. A nonlinear regime-shifting regression model of Markov Regime Shifting (MRS) is used to understand the impact of news on sovereign bond yield spreads. The paper results show that textual news sentiment may explain both steepening and flattening of the yield curve, with monetary and fiscal policy news having the most significant impact on yield spread behaviour. The results hold key implications for policymakers, debt fund managers and other market participants.

Buying into new ideas: the ECB’s evolving justification of unlimited liquidity

Abstract In 2012, Draghi put an end to rising euro area sovereign bond yield spreads by resolving to do ‘whatever it takes’. The crisis rhetoric and institutional practices of unlimited liquidity have since become commonplace, as countermeasures to recent market turmoil show. This article sets out to explain how and why ‘unlimited liquidity’ ideas moved to the ECB’s center of economic analysis during the euro crisis. Previous work fails to decipher that the ideational shift was highly anomalous when viewed against German ordoliberalism or scholarly support for ‘expansionary austerity’. Addressing this relative neglect in other accounts, we draw on qualitative text analysis and expert interviews to argue that this shift was due to norm entrepreneurs who capitalized on the uncertainty of the crisis. We employ constructivist arguments to identify four scoping conditions that account for the ascendance of ‘unlimited liquidity’: an indicative reference, credibility, institutional positioning and—as an extension to the literature—intellectual sensitivity. Our analysis suggests that the euro crisis changed economic ideas, and fundamentally remodels the constructivist framework for studying monetary policy in crisis times.

Detecting business cycles for Hungarian leading and coincident indicators with a Markov switching dynamic model to improve sustainability in economic growth

This paper applies the hidden Markov switching dynamic regression (MSDR) model to estimate transition probabilities of the Hungarian GDP between recessionary and expansionary periods. The transition probabilities are then compared to the OECD Hungarian binary business cycle indicator to assess the predictive power of the model. The paper proposes a linear model with a mean and a homoscedastic component. The level of symmetricity between the GDP and business cycles is explained by the panel data variables (Unemployment rate, IPI index, Inflation, BUX year-on-year change, and 10-3 Year sovereign bond yield spreads). It is assumed in this paper that by extending the model to encompass an exogenous variable listed in the panel data, essentially making the model bivariate, the maximum likelihood function would capture the business cycle more accurately. The results show that by plugging the unemployment rate as the exogenous variable in the regression, our model’s accuracy is 70%.

Transmission of the Greek crisis on the sovereign debt markets in the euro area.

We test for the contagion effects stemming from the Greek debt crisis in the daily 10-year sovereign bond yield spreads in nine Economic and Monetary Union (EMU) countries. To this end, we estimate the dynamic conditional correlation (DCC) model of Engle (2002) from January 01, 2003 to December 31, 2015. In addition, we calculate and plot the upper and lower bounds of the confidence interval for each DCC series. To the best of our knowledge, this approach of Kchaou and Bellalah (2020) has never been used to study the contagion of the subprime and Greek crises between the 10-year sovereign bond yield spreads of the main EMU countries. Consequently, this approach enables us to compare our results with those of previous works based on other methods. It also offers useful insights to policy makers to address the contagion effect through the implementation of adequate measures. Although the Greek spread played the role of a global factor for the majority of countries during the observation period, the results invalidate the existence of contagious episodes resulting from the Hellenic crisis. We justify these findings either by the weakness of the weight of the Greek economy in the euro area or by the effectiveness of the unconventional monetary policies taken by the European Central Bank (ECB), the bailouts for Greece in 2010, 2012 and 2015 and the austerity measures and structural reforms implemented by the governments of EMU countries. Moreover, DCC between Greece and the other countries have shown a downward behavior during the acute phases of Greek crisis, suggesting a disintegration of the Hellenic bond market with those of other euro area countries during periods of financial turmoil. Furthermore, the results indicate that the subprime crisis affected a large part of these markets well before the bankruptcy of Lehman Brothers. All these findings provide valuable information for international investors, central bankers and policymakers.

Monetary policy expectations and sovereign risk dynamics in the Eurozone

Abstract We empirically assess the dynamic linkages among sovereign bond yield spreads (both short- and long-term) and monetary policy rates/spreads during the Eurozone’s sovereign and banking crises in the post-2008 period when unconventional monetary policy replaced conventional policy. Our focus is on two subperiods, the crisis period (30 November 2009 to 25 July 2012) and the tranquil period (26 July 2012 to 30 April 2014). For the first subperiod, we noted significant spillovers from the overnight interest spreads spread to almost all sovereign bond yield spreads, at both the mean and volatility levels. Thus, during that period expectations on monetary surprises led bond spreads and their corresponding volatilities compared to the tranquil period, regardless of the bond yields maturities. Overall, we infer that monetary policy and sovereign risk were highly linked during the crisis period and thus, the interest-rate monetary policy transmission mechanism was effective in reducing these yield spreads.

Measuring redenomination risks in the Euro area – evidence from survey data

PurposeThis paper aims to introduce a new indicator to measure redenomination risks in Euro area countries. The measure is based on survey data. The influence of this indicator in determining sovereign bond yield spreads is estimated.Design/methodology/approachAn autoregressive distributed lag approach is used to estimate the effects of redenomination risks on sovereign bond yields. Additional control variables are added.FindingsThe results for 10 European Economic and Monetary Union (EMU) countries in the period June 2012 to May 2019 show that the risk of depreciation is almost abandoned for most Euro area countries, i.e. the former crisis countries Ireland and Portugal. If anything an appreciation may occur for some countries once they leave the EMU. The only countries facing depreciation problems once leaving the monetary union are Italy and to some extent Spain.Originality/valueWith this new indicator, the literature on sovereign bond determination and i.e. on redenomination risks is expanded by an additional approach. Moreover, this study is one of few also looking at the period after the most severe tensions of the sovereign debt crisis in the Euro area in 2012.

Emotions in macroeconomic news and their impact on the European bond market

We show how emotions extracted from macroeconomic news can be used to explain and forecast future behaviour of sovereign bond yield spreads in Italy and Spain. We use a big, open-source, database known as Global Database of Events, Language and Tone to construct emotion indicators of bond market affective states. We find that negative emotions extracted from news improve the forecasting power of government yield spread models during distressed periods even after controlling for the number of negative words present in the text. In addition, stronger negative emotions, such as panic, reveal useful information for predicting changes in spread at the short-term horizon, while milder emotions, such as distress, are useful at longer time horizons. Emotions generated by the Italian political turmoil propagate to the Spanish news affecting this neighbourhood market.

Sovereign bond yield spreads spillovers in the Economic and Monetary Union

AbstractWe study the sovereign bond market co‐movements and spillovers within 10 EMU countries, the so‐called “periphery” and “core” countries, during the period 1999:01 to 2016:07. Implementing Generalized Methods of Moments (GMM) within a panel setting and bivariate VAR analysis, we find that an increase in the lagged spreads of Italian and Austrian bonds negatively affect the spreads of the whole sample while the increase in the Irish, Portuguese, Belgian and French lagged yields increased the overall spreads. In the VAR analysis we find that spillover effects within the sample are mostly positive.

The effects of macroeconomic, fiscal and monetary policy announcements on sovereign bond spreads

We assess the impact of announcements corresponding to different fiscal and monetary policy measures on 10-year sovereign bond yield spreads (relative to Germany) of 10 EMU countries during the period 01:1999-07:2016. Implementing country-fixed effects OLS regressions, we find that the European Commission’s (EC) releases of the excessive deficit procedure significantly affect yield spreads. The EC releases of higher debt and better budget balance forecasts contribute to the rise and the decline of spreads, respectively. Moreover, we find that the announcements of the ECB’s key interest rates together with the longer-term refinancing operations (LTROs) and the first covered bond purchase programme (CBPP1) negatively affect sovereign yield spreads in our sample of EMU countries. There was also some capital market mispricing of the sovereign bond risk in the Euro area before the Global Financial Crisis, notably regarding government debt forecasts.

Interest premium and external position: A state dependent approach

Using a broad sample of countries between 1980 and 2017, this paper re-examines the empirical relationship between sovereign yield spreads and the level of external indebtedness of advanced, emerging and less-developed economies in both normal and crisis periods. It finds a significant relationship that is much stronger during crisis periods and its strength decreases with the level of economic development. It also shows that this relationship is non-linear which is primarily driven by periods of financial crises. We carry out a number of robustness checks, which highlight issues related to sample composition, the definition of sovereign bond yield spreads and crisis events. In all checks, our results are largely unchanged. These findings have a number of implications with regard to the calibration of macroeconomic models and debt sustainability analysis.

Uncertainty in Euro area and the bond spreads

We investigate potential mean and volatility spillovers among sovereign bond yield spreads for five peripheral countries of the euro area. We focus on Greece, Ireland, Italy, Portugal and Spain during the European sovereign debt crisis. We propose a bootstrap bias-corrected bivariate Vector Autoregressive Moving Average (VARMA), GARCH-in-Mean, asymmetric BEKK model, and find that the level and the volatility of a bond yield spread are mainly dependent on its own past volatility, and thus, its past shocks mainly affect its volatility. Based on our findings, we suggest that the number one priority of the European policymakers be the economic and financial integration of the European peripheral countries into the core.

Sovereign bond yield spreads and sustainability: An empirical analysis of OECD countries

Abstract We study whether and how a country's environmental, social, and governance (ESG) performance relates to its sovereign borrowing costs in international capital markets. We hypothesize that good ESG performance plays an economic role: It signals a country's commitment to sustainability and long-term orientation and is a buffer against negative shocks, leading to lower sovereign bond yield spreads. Using a sample of 20 OECD countries over the period 1996–2012, we show that countries with good ESG performance are associated with lower default risk and lower sovereign bond yield spreads. Moreover, we show that the social and governance dimensions have a significant negative association with sovereign bond yield spreads, whereas the environmental dimension does not.

Quantitative easing and sovereign yield spreads: Euro-area time-varying evidence

We assess the determinants of sovereign bond yield spreads in the period 1999:01–2016:07, considering non-conventional monetary policy measures in the Euro area. We use a 2-step approach to: (i) confirm and estimate the determinants of sovereign bond yield spreads; (ii) compute bivariate time-varying coefficient (TVC) models of each determinant and analyse the temporal dynamics. The baseline determinants of sovereign bond yield spreads in the Euro area are the bid-ask spread, the VIX, fiscal developments and rating developments, REER, and economic growth. QE measures implemented by the ECB in the aftermath of the crisis are also relevant. From the TVC analysis, the Covered Bond Purchase Programme contributed to reduce yield spreads, particularly in the 2011–2013 period. Longer-term refinancing operations contributed to reduce yield spreads in most countries.

Sovereign Bond Yield Spreads Spillovers in the EMU

We study the sovereign bond market co-movements and spillovers within 10 EMU countries, the so-called “periphery” and “core” countries, during the period 1999:01 to 2016:07. Implementing Generalized Methods of Moments (GMM) within a panel setting and bivariate VAR analysis, we find that an increase in the lagged spreads of Italian and Austrian bonds negatively affect the spreads of the whole sample while the increase in the Irish, Portuguese, Belgian and French lagged yields increased the overall spreads. In the VAR analysis we find that spillover effects within the sample are mostly positive.

The importance of being earnest

PurposeThis paper aims to provide an empirical analysis of the macroeconomic determinants of sovereign bond yield spreads in the Eurozone from 2000 until August 2012, when the Outright Monetary Transactions programme was launched.Design/methodology/approachThe authors constructed an unbalanced panel with quarterly data from 2000 Q1 to 2012 Q2 for the 12 Eurozone countries: Austria, Belgium, Finland, France, Germany, Greece, Ireland, Luxembourg, Italy, The Netherlands, Portugal and Spain. The authors propose a model that explains spreads through the main categories of variables observed in the literature. The relationship between variables is analysed using ordinary least squares and quantile regressions. As discussed by the authors, quantile regressions provide a more precise estimation, given the huge heterogeneity across counties that can be observed in the Eurozone.FindingsResults show that the relationship between sovereign risk and macroeconomic fundamentals is affected by a strong country sentiment effect. The impact of country sentiment on sovereign risk is larger for those countries that were already experiencing higher spreads. Regardless the impact that European Central Bank’s (ECB) intervention had on sovereign risk from 2012, quantile regression results suggest that policy recommendations and goals should be adapted to each country’s market perception.Originality/valueThe results obtained improve on previous findings on this topic (De Grauwe and Ji, 2012) in two ways. First, they show that even introducing every category of determinants found in the literature in the main specification, fundamentals can only partially explain the evolution of sovereign risk in the Eurozone. Second, they find there is a country-sentiment effect that affects the relationship between macroeconomic indicators and sovereign risk. Furthermore, the paper finds that the country-sentiment effect is larger for countries facing high spreads.

“Whatever it takes” to resolve the European sovereign debt crisis? Bond pricing regime switches and monetary policy effects

This paper investigates the role of unconventional monetary policy as a source of time-variation in the relationship between sovereign bond yield spreads and their fundamental determinants. We use a two-step empirical approach. First, we apply a time-varying parameter panel modelling framework to determine shifts in the pricing regime characterising sovereign bond markets in the euro area over the period January 1999 to July 2016. Second, we estimate the impact of ECB policy interventions on the time-varying risk factor sensitivities of spreads. Our results provide evidence of a new bond-pricing regime following the announcement of the Outright Monetary Transactions (OMT) programme in August 2012. This regime is characterised by a weakened link between spreads and fundamentals, but with higher spreads relative to the pre-crisis period and residual redenomination risk. We also find that unconventional monetary policy measures affect the pricing of sovereign risk not only directly, but also indirectly through changes in banking risk. Overall, the actions of the ECB have operated as catalysts for reversing the dynamics of the European sovereign debt crisis.

Whatever It Takess to Resolve the European Sovereign Debt Crisis? Bond Pricing Regime Switches and Monetary Policy Effects

Cost of sovereign debt and foreign bias in bond allocations

Finance theory suggests that markets where foreign bond portfolio investors overweight their portfolio relative to the prescribed theoretical benchmark should experience higher international risk sharing. Correspondingly, the cost of debt in such markets should be lower compared to markets facing a lower degree of international risk sharing. We empirically examine this prediction using a panel data set of sovereign bond yield spreads and a measure of suboptimal foreign bond portfolio allocations for 50 emerging and ten developed markets. Consistent with theory, our results show higher levels of foreign bond allocations – relative to the theoretical benchmark – are negatively related to the cost of debt. These results have important policy implications as a country’s cost of debt could potentially be lowered by encouraging foreign portfolio investors to hold their optimal allocation.

Convergence patterns in sovereign bond yield spreads: Evidence from the Euro Area

This study examines the convergence patterns of Euro Area (EA) 17 countries’ sovereign bond yield spreads (relative to German bund) over the period of March 2002 to December 2015, by employing the convergence algorithm developed by Phillips and Sul (2007). The empirical findings suggest rejection of full convergence across the EA17 countries’ bond yields spreads, and the presence of a certain number of clubs. In particular, three subgroup convergence clubs emerge, with Cyprus, Spain, France, Greece, Ireland, Lithuania, Luxembourg, Latvia, Portugal and Slovenia in the first; Belgium, Italy and Malta in the second; and Austria, Finland, Netherlands and Slovakia in the third club. Moreover, there is also evidence that the first two clubs could be merged to form a larger convergence club. The transitional curves indicate that, despite short-run divergences, EU17 sovereign bond yield spreads tend to converge in the long-run, with the exception of those in Greece and Cyprus, indicating the strong attempts of most of the countries under investigation to adopt fiscal policies that eventually contribute to a convergence pattern.
