European policy and markets: Did policy initiatives stem the sovereign debt crisis in the euro area?

We investigate how European policy initiatives influenced market assessments of sovereign default risk and banking sector fragility during the sovereign debt crisis in four adversely affected countries — Portugal, Ireland, Spain and Italy. We focus on three broad groups of policies: (a) ECB policy actions (monetary and financial support), (b) EU programs (financial and fiscal rules as well as financial support in crisis countries), and (c) domestic austerity programs. We measure immediate market impact effects: what policies changed risk perceptions, using CDS spreads on sovereign bonds and banks in this assessment. We employ dynamic panel and event study methodologies in the empirical work. We find that a number of programs initially stabilized sovereign and bank bond markets (e.g. Outright Monetary Transactions program), although announcement and implementation impacts on markets differed in some cases (e.g. second Covered Market Bond Program). Actions designed to shore up sovereign markets often lowered risk assessments in bank bond markets and policies designed to ensure safety and soundness of the European banking system in some cases significantly impacted sovereign debt markets. Finally, a number of policies designed to stabilize markets had surprisingly little immediate impact on either sovereign or bank bond market risk assessments.     

Fundamentals and Sovereign Risk of Emerging Markets

We empirically assess the relative importance of various economic fundamentals in accounting for the sovereign credit default swap (CDS) spreads of emerging markets during 2004–2012, which encompasses the global financial crisis of 2008–2009. Inflation, state fragility, external debt and commodity terms of trade volatility were positively associated, while trade openness and a more favourable fiscal balance/GDP ratio were negatively associated with sovereign CDS spreads. Yet the relative importance of economic fundamentals in the pricing of sovereign risk varies over time. The key factors are trade openness and state fragility in the pre‐crisis period, the external debt/GDP ratio and inflation in the crisis period, and inflation and the public debt/GDP ratio in the post‐crisis period. Asian countries enjoy lower sovereign spreads than Latin American countries, and this gap widened during and after the crisis. Trade openness was the biggest factor behind Asia's lower sovereign spreads before the crisis, and inflation during and after the crisis. The results imply that external factors were paramount in pricing sovereign risk prior to the crisis, but internal factors associated with the capacity to adjust to adverse shocks gained prominence during and after the crisis.     

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.     

Dynamic interdependence of sovereign credit default swaps in BRICS and MIST countries

This article examines the interactions of emerging markets sovereign credit default swaps (CDS). Using a generalized vector autoregressive framework and principal component analysis, we find significant spillover effects within the two groups of emerging markets under study. Using the principal component analysis, we show that global financial market factors are important drivers of BRICS and MIST sovereign CDS spreads variability. Focusing on the forecast error variance decomposition, most of the spillover effects are documented among the emerging markets CDS. Brazil and Mexico contribute the largest net directional spillovers to the other emerging markets studied.

Highlights:

• There exist significant CDS spillover effects for MIST and BRICS countries.

• Mexico dominates the spillover effects within the MIST group while Brazil dominates the spillover effects within the BRICS group.

• As determined by principal component analysis, global financial market factors are important drivers of BRICS and MIST sovereign CDS spreads variability.

• There exists a relatively small net directional spillover from global financial market factors to the countries under study; however, the total spillover is time-varying.

• A large proportion of the forecast error variance in the markets studied comes from spillovers.

     

Firm credit risk in normal times and during the crisis: are banks less risky?

Bank solvency was a major issue during the financial crisis of 2007–2009, but bank credit default swap (CDS) spreads were almost always below nonbank CDS spreads. What is the reason for this gap? Are banks perceived to be less risky? This study empirically decomposes CDS premia for 45 major banks and 167 large industrial firms from Europe and the US. It turns out that expected losses are usually somewhat lower for banks than for nonbanks, but expected losses contribute relatively little to the observed CDS premia. CDS spreads for banks and nonbanks differ mainly because market participants require a lower compensation for bearing bank credit risk. The quite persistent difference in the credit risk premia for banks and nonbanks disappears only temporarily during the crisis.     

Comments on “Consumption Values of Trade Unions”

The credit default swap (CDS) is implicated in the global financial crises because a vast market for securities collateralized by subprime mortgages and consumer debt could not have materialized if hedge funds and other holders of these instruments lacked a means of hedging default "risk." The argument is made that the CDS is an inherently defective concept because it is based on the assumption that future states of the economy are subject to probabilistic risk as opposed to uncertainty in the Keynes-Knight-Shackle-Davidson sense. The CDS also manifests the paradox of derivatives. By enabling individual money managers to safely increase leverage, it causes a system-wide buildup of leverage and financial fragility.     

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.     

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 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.     

Modeling the dependence structure between default risk premium,equity return volatility and the jump risk: Evidence from a financial crisis

This paper investigates the dependence structure between default risk premium, equity return volatility and jump risk in the equity market before and during the subprime crisis. Using iTraxx CDS index spreads from Japanese and Australian markets, the paper models the different relationships that can exist in different ranges of behavior. We consider several Archimedean copula models with different tail dependence structures, namely, Gumbel, Clayton, Frank, AMH and Joe copulas. Although the dramatic change in the levels of the iTraxx CDS index, we find strong evidence that the dependence structure between CDS and stock market conditions is asymmetric and orienting toward the upper side. In addition, we find that the Japanese CDS market is more sensitive to the stock return volatility than the jump risk and the magnitude of this sensitivity is related to the market circumstances. However, Australian CDS market is more sensitive to the jump risk than stock return volatility before and during the financial crisis. This result has important implications for both global financial stability and default risk management. Specifically, the heterogeneity of markets, coupled with the diversity in the risk exposures cause the default risk premium and equity markets to exhibit different levels of sensitivity.

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.     

Does a one-size-fits-all approach to financial regulations alleviate default risk? The case of dual banking systems

Financial regulations are developed to curb financial and economic fragility costs without undermining the economic contributions of banks to economic development. To understand the impact financial regulations have on reducing the financial fragility of banks we use the probability-of-default of banks as a proxy for bank failure. After analyzing data collected from 15 countries with a dual banking system for the period 2000–2015, we find convincing evidence that not all financial regulations have risk-reducing benefits for banks and the impact of financial regulations on default risk is not the same for conventional banks (CBs) and Islamic banks (IBs). The empirical evidence suggests that regulations that lessen overall default risk have a greater impact on IBs while those increasing default risk have a greater impact on CBs. Based on our findings we recommend that regulators should consider the different natures of CBs and IBs and tailor financial regulations to suit these operationally distinct financial intermediaries.     

The relationship between risk-neutral and actual default probabilities: the credit risk premium

The study investigates empirically the relationship between the risk-neutral measure Q and the real-world measure P. We study the ratio between the risk-neutral and actual default intensities, which we call the coverage ratio or the relative credit risk premium. Actual default intensities are derived from rating agencies annual transition matrices, while risk-neutral default intensities are bootstrapped from CDS quotes of European corporates. We quantify the average risk premium and its changes over time. Compared to related literature, special attention is given to the effects of the recent financial and European sovereign crises. We find that average credit risk premia rose substantially and that post-crisis levels are still higher than those observed before the financial crisis. This observation is especially true for high-quality debt and if it persists, it will have an impact on corporates funding costs. The quantification and revision of risk premia contributes to the discussion of the credit spread puzzle and could give extra insights in valuation models that start from real-world estimates. Our work is furthermore important in the context of state aid assessment. The real economic value (REV) methodology, applied by the European Commission to evaluate impaired portfolios, is based on a long-term average risk premium.     

Does ownership concentration affect banks’ credit risk? Evidence from MENA emerging markets

The purpose of this study is to explore the impact of ownership concentration on banks’ credit risk. The study employs a dynamic panel approach using data from 98 banks listed in the 10 Middle East and North African (MENA) emerging stock markets between 2003 and 2016. To better understand the nature of the relationship between ownership concentration and bank credit risk and how this relationship is shaped by the recent financial crisis, we conducted a pre- and postcrisis analysis. Our findings document a positive relationship between ownership concentration and nonperforming loans in the precrisis period, which surprisingly reverses during the postcrisis period. We argue that the reversal of this relationship is driven by changes in controlling shareholders’ risk aversion, behavior, and attitude prompted by the financial crisis. Given that central banks are entrusted with forestalling banks’ failure, incorporating ownership concentration, as a fundamental determinant of banks’ credit risk, is crucial to anticipate future financial calamities. Our findings highlight the gravity of agency problems in emerging MENA markets. Reinforcing firm-level as well as country-level governance mechanisms is crucial to restore a sound banking system, enhance markets’ integrity, and increase investors’ confidence.     

Sudden Stops,Time Inconsistency,and the Duration of Sovereign Debt

We study the sovereign debt duration chosen by the government in the context of a standard model of sovereign default. The government balances off increasing the duration of its debt to mitigate rollover risk and lowering duration to mitigate the debt dilution problem. We present two main results. First, when the government decides the debt duration on a sequential basis, sudden stop risk increases the average duration by 1 year. Second, we illustrate the time inconsistency problem in the choice of sovereign debt duration: governments would like to commit to a duration that is 1.7 years shorter than the one they choose when decisions are made sequentially.     

The risk of the sovereign debt default: the Eurozone crisis 2008–2013

We investigate the relationship of the market pricing of sovereign risk to default, through credit default swap (CDS) spreads for 16 Eurozone countries during 2008q1–2013q3. We take into account, through appropriate non-linear generalized method of moments (GMM) estimations the endogeneity problem. We focus on ‘fiscal space’ (DEBT or FISCAL), and the downgrade announcements (DOWN). We find DEBT (FISCAL) to have significant (insignificant) effects on the CDS concave function, as well as, DOWN in a linear one. It has also been confirmed significant pricing discrimination between South and West Euro Area Periphery (SWEAP) and the core Eurozone, highlighting asymmetries discovered either by the respective size of estimated DEBT coefficients or by the significant effects of DOWN that have only on CDS of SWEAP countries. The current account balance or the inflation rate, as well as, relevant interaction terms seem not to affect the spreads of the EMU. These findings, together with the estimated structural change on CDS pattern in early 2011, coinciding with significant either the DOWN in the pre-crisis period (2008–2010) or the DEBT in the post-crisis one (2011–2013) on the CDS, seem to be consistent with self-fulfilling crises literature and the inherent vulnerability of EMU, on other words, the ‘fragility hypothesis of the Eurozone’.     

Banking reforms,performance and risk in China

We investigate the impact of the banking reform started from 2005 on ownership structures in China on commercial banks’ profitability, efficiency and risk over the period 2000–2012, providing comprehensive evidence on the impact of banking reform in China. We find that banks on average tend to have higher profitability, lower risk and lower efficiency after the reforms, and the results are robust with our difference-in-difference approach. Our results also show that the Big 5 state-owned banks (SOCB) underperform banks with other types of ownership when risk is measured by non-performing loans (NPLs) over the entire study period but tend to have fewer NPLs than other banks during the post-reform period. Our results provide some supporting evidence on the ongoing banking reforms in China, suggesting that attracting strategic foreign investors and listing SOCBs on stock exchanges appear to be effective ways to help SOCBs deal with the problem of NPLs and manage their risk.     

Do stress tests matter? A study on the impact of the disclosure of stress test results on European financial stocks and CDS markets

During the recent sovereign debt crisis, the European Banking Authority conducted two stress tests on European banks in order to gauge their capital needs, core Tier-1 ratios and ratios of resilience to adverse shocks. We assess the informational content of the disclosure of the stress test outcomes. We conclude that the stress tests conveyed new information and that the outcomes were not anticipated by the stock market but were partially anticipated by the credit default swap (CDS) market. However, while the stock market reacted to the disclosure of the stress test outcomes, in the CDS market there is some evidence of a ‘reverse’ reaction. Moreover, the publication of the outcomes of the stress tests had a stronger impact on the stock prices of riskier financial institutions. A similar pattern is evident in the CDS market, albeit narrowed to one of the stress tests and amid the financial institutions with higher perceived credit risk.     

Sovereign Risk and Out‐of‐Equilibrium Exchange Rate Dynamics

We show that the sovereign risk premium contains important information on short‐run exchange rate dynamics in emerging economies. Net foreign assets serve as the key link between both variables, which acts as a “crude form of collateral.” We present two sets of empirical evidence. First, we show that increases in net foreign assets provide a statistically significant reduction on emerging markets sovereign risk premium. Then, we show that out‐of‐sample forecasts using realized values for the sovereign risk premium have a satisfactory performance when evaluated across three metrics: the mean squared error ratio, the direction of change statistic, and the consistency criterion.
