Domestic Banks As Lightning Rods? Home Bias and Information during the Eurozone Crisis

European banks have been criticized for holding excessive domestic government debt during the recent Eurozone crisis, which may have intensified the diabolic loop between sovereign and bank credit risks. By using a novel bank-level data set covering the entire timeline of the Eurozone crisis, I first reconfirm that the crisis led to the reallocation of sovereign debt from foreign to domestic banks. In contrast to the recent literature focusing only on sovereign debt, I show that the banks' private-sector exposures were (at least) equally affected by the rise in home bias. Consistent with this pattern, I propose a new debt reallocation channel based on informational frictions and show that the informationally closer foreign banks increase their relative exposures when the sovereign risk rises. The effect of informational closeness is economically meaningful and robust to the use of different information measures and controls for alternative channels of sovereign debt reallocation.     

欧元区主权债务危机对国际金融市场的影响及启示

欧元区主权债务危机爆发两年多来,全球股市纷纷下挫、走势低迷,外汇市场也随着债务危机的延伸而跌宕起伏。旷日持久的债务危机不仅对国际金融市场造成巨大冲击,加剧了国际资本流动的频繁无序,且已导致欧洲银行体系的信用风险加大和流动性紧张等问题。欧元区主权债务危机的爆发,提醒我们要全面审视中国的主权债务问题,尤其要加强对地方政府债务的监管,以防范债务危机的发生。     

Dynamic spillover effects in futures markets: UK and US evidence

Previous studies on spillover effects in futures markets have so far confined themselves to static analyses. In this study, we use a newly introduced spillover index to examine dynamic spillovers between spot and futures markets volatilities, volume of futures trading and open interest in the UK and the US. Based on a dataset over the period February 25, 2008 to March 14, 2013, that encompasses both the global financial crisis and the Eurozone debt crisis, we find that spot and futures volatilities in the UK (US) are net receivers (net transmitters) of shocks to volume of futures trading and open interest. The analysis also sheds light on the dynamic interdependence of spot and futures markets volatilities between the US and the UK. Specifically, the spot and futures volatility spillovers between the UK and US markets are of bidirectional nature, however, they are affected by major economic events such as the global financial and Eurozone debt crises. Several robustness checks endorse our main findings. Overall, these results have important implications for various market participants and financial sector regulators.     

Modelling correlation dynamics of EMU sovereign debt markets during the recent turmoil

The purpose of the present study is to explicitly model the correlation dynamics of Eurozone sovereign debt markets. Our analysis runs from 2000 through 2014. Time varying correlations are derived from a dynamic conditional correlation GARCH model (t-cDCC model). We document substantial variability in correlations that is time and region-dependent. Evidence suggests that the Lehman collapse coupled with the German banks’ bailout programme and the events that followed have undermined sovereign debt integration. Moreover, sensitivity analysis provides useful insights that global and regional risk factors play pivotal role in explaining correlation structure both before and after the onset of the Eurozone sovereign debt crisis. We believe that our results entail important implications for market authorities, international fixed income portfolio diversification and asset allocation.     

What is the risk of European sovereign debt defaults? Fiscal space,CDS spreads and market pricing of risk

We estimate the pricing of sovereign risk for fifty countries based on fiscal space (debt/tax; deficits/tax) and other economic fundamentals over 2005–10. We focus in particular on five countries in the South-West Eurozone Periphery, Greece, Ireland, Italy, Portugal and Spain. Dynamic panel estimates show that fiscal space and other macroeconomic factors are statistically and economically important determinants of sovereign risk. However, risk-pricing of the Eurozone Periphery countries is not predicted accurately either in-sample or out-of-sample: unpredicted high spreads are evident during global crisis period, especially in 2010 when the sovereign debt crisis swept over the periphery area. We match the periphery group with five middle income countries outside Europe that were closest in terms of fiscal space during the European fiscal crisis. Eurozone Periphery default risk is priced much higher than the matched countries in 2010, even allowing for differences in fundamentals. One interpretation is that these economies switched to a “pessimistic” self-fulfilling expectational equilibrium. An alternative interpretation is that the market prices not on current but future fundamentals, expecting adjustment challenges in the Eurozone periphery to be more difficult for than the matched group of middle-income countries because of exchange rate and monetary constraints.     

欧洲主权债务危机演进及对中资银行的启示

受全球金融危机的持续影响和欧元区制度问题的激化,欧洲主权债务危机呈愈演愈烈之势,逐步从边缘国家扩散至核心国家,并从主权债务危机向银行业危机演化。目前,欧元区重债国采取的财务整顿政策难以在短期发挥缩减赤字的作用,反而加大复苏风险;对重债国援助资金总量有限,其发放门槛徒增短期违约风险;欧洲央行购买国债虽有利于缓解危机恶化,但量化宽松的政策与其控制通胀的设立宗旨存在矛盾。在此背景下,中资银行应调整涉欧资产配置,进一步加强国别风险研究和管理,积极稳健地推进国际化经营,打造资产、业务和经营地域多元化的国际化银行。     

Is small beautiful? The resilience of small banks during the European debt crisis

We examine the lending behaviour of small and large banks in the Eurozone during the sovereign debt crisis. Relative to large banks, small banks are less pro-cyclical in that they exhibit more stable lending growth across credit expansion and contraction periods. In peripheral countries, the portfolio rebalancing of small banks towards higher public debt (substitution effect) does not appear to cause a reduction of their lending to the private sector. Instead, the level of public debt seems to provide a liquidity buffer that influences bank-specific loan growth positively (complementarity effect), particularly during market-wide lending contractions. Our findings show that for small peripheral banks the substitution effect found in the literature can coexist with a complementarity effect when public debt grows faster than private loans. Our analysis contributes to the ongoing debate on the regulatory treatment of public debt in banks and supports incentives embedded in new banking regulation that penalise bank size.     

Euro at risk: The impact of member countries' credit risk on the stability of the common currency

In this paper, we propose a new indicator of Euro stability. We make use of this new indicator and empirically investigate the impact of changes in sovereign risk of Eurozone member countries on the stability of the Euro. The stability of the Euro is proxied by decomposing Dollar–Euro exchange rate options into the moments of the risk-neutral distribution. Our stability measure can nicely separate periods of Dollar instability (the subprime crisis period) and Euro instability (the sovereign debt crisis period). In particular, we document that only during the sovereign debt crisis, changes in the creditworthiness of member countries with vulnerable fiscal positions have a significant impact on the stability of the common currency. Interestingly, however, the market perceives Greece not to be ‘systemically relevant’.     

Factor decomposition of the Eurozone sovereign CDS spreads

In the present study, we examine the factors driving Eurozone sovereign credit default swap (CDS) spreads during the Eurozone sovereign debt crisis. For identifying factors we utilize independent component analysis (ICA), a technique similar to principal component analysis (PCA). We identify three factors that impact spreads and capture the features specific to the crisis such as the breakup risk of the Eurozone: peripheral factor, global factor, and Eurozone common factor. In contrast, when PCA is applied, only a single factor is identified. Moreover, using ICA with a GARCH model, we show that the source of volatility for CDS spreads shifted from the global factor in 2009 and the peripheral factor in 2010 to the Eurozone common factor in 2012, and that the dynamic correlation reflects the decoupling between low credit risk countries such as Germany and high credit risk countries such as Greece. We also show that the goodness-of-fit of the ICA-based model is better than other models used such as the Student's t copula model.

关于欧洲主权债务问题与欧元区域制度改革的思考

近来,希腊、葡萄牙、西班牙和爱尔兰等多个欧元区国家均面临主权债务违约风险。这一问题的发生,既有希腊等国自身财政管理的原因,也反映出欧元区体制中存在的一系列长期性、结构性和制度性问题。如果不能妥善解决欧元区国家的主权债务问题,不仅将拖累欧元区经济发展,也会对世界经济金融复苏造成冲击。欧洲主权债务问题的出现,对我国财政预算管理也有一定警示作用。     

A Theoretical and Empirical Review of the EU Regulation on Credit Rating Agencies: In Search of Truth,Not Scapegoats

The undergoing financial turbulence has raised significant concerns over the role that credit rating agencies (CRAs) played in the inception, magnification and expansion of the crisis. In response, the EU legislature has adopted Regulation 1060/2009, which, for the first time, set out a legally binding pan‐European authorization regime for CRAs, which issue ratings that have been used by EU‐based financial institutions. As the turmoil turned into an unprecedented Eurozone debt crisis, EU politicians have been calling for tighter regulation of the credit rating industry. Drawing on the relevant empirical and theoretical research and building upon a comparative study of the corresponding US framework, the paper discusses critically the principles underlying EU Regulation 1060/2009 and the most recent suggestions for its reform. The paper argues that although, overall, the EU Regulation seems to be a well‐balanced instrument in the sense that it introduces the essential checks upon CRAs’ behavior while avoiding excessive regulatory intervention, more fine‐tuning is needed in certain fields, including, rating shopping, financial ties with rated entities, abuse of inside information, transparency and CRAs’ accountability.     

Question the Unquestionable Beauty of A Collective Proceeding for All Sovereign Debt Claims

The new challenges presented by the current Eurozone crisis and the NML Capital v. Argentina case are likely to shift the international community's attention from holdout behavior in foreign bonds restructuring to inter‐creditor issues. In the past years, many academics, and nongovernmental organizations concerned with debt relief, have put forward proposals to create a bankruptcy regime for states. But none of these proposals has seriously examined what rules should apply to treatment among creditors. Moreover, all insist that there must be a collective proceeding for all sovereign debt claims, without explaining why. This approach is simply taken for granted, as it is one of the fundamental principles of bankruptcy law. The article questions this orthodoxy through examining the nature of sovereign debt crisis, the feature of the limited pool of sovereign assets, and the nonliquidable fact of the sovereign debtor. It also argues that the common pool problem does not exist in the sovereign debt context.

Volatility spillovers and hedging effectiveness between the oil market and Eurozone sectors: A tale of two crises

This paper aims to analyze the mean and volatility spillovers between oil prices and the Eurozone supersector returns. It uses daily data of the Brent prices and 19 Eurozone supersector indices for the period from August 2004 to August 2015. This area experienced two important instabilities in that period, the global financial crisis (GFC) and the Euro debt crisis (EDC). Because financial turbulences are suspected to induce changes in the volatility dynamics, the full sample is divided into three sub-samples. Empirically, this study employs a bivariate VAR-BEKK-GARCH model that allows for transmission in volatility. The obtained volatilities and covariances are used to compute the optimal weights and hedge ratios for oil–stock portfolio holdings. The findings show that both mean and volatility spillovers between the oil market and the different Eurozone sectors are time-varying and heterogeneous. In the GFC sub-period, there is evidence of contagion effects because there is an intensification of volatility spillovers. The EDC does not seem to have induced any particular change in the spillover effects. The optimal weights, hedge ratios, and correlation analysis results allow an accurate understanding of the time series relationship between the two markets and are useful for financial market participants and policymakers.     

The European fiscal reform and the plight of the euro

This paper presents the background and development of the global crisis of 2007–2008 and subsequent developments that are current today. It distinguishes four phases of the crisis: sub-prime mortgage crisis, soaring dollar and the Lehman Brothers fiasco, US and global recession, and, finally, European debt crisis. In the above context, the benefits and costs of joining the Eurozone are presented with special emphasis on the Polish perspective. The need for fiscal reforms and concerns regarding Eurozone institutions are addressed.The paper has been prepared based on the keynote speech by Robert Mundell during the 17th Global Finance Conference held in Poznan, Poland in June 2010. The speech presented was made possible in part by support from the Polish Financial Supervision Authority.An early version of the paper has been previously published in the Poznan University of Economics Review.     

Subsidiary debt,capital structure and internal capital markets

I study external debt issued by operating subsidiaries of diversified firms. Consistent with Kahn and Winton's [2004. Moral hazard and optimal subsidiary structure for financial institutions. Journal of Finance 59, 2537–2575] model, where subsidiary debt mitigates asset substitution, I find firms are more likely to use subsidiary debt when their divisions vary more in risk. Consistent with subsidiary debt mitigating the free cash flow problem, I find that subsidiaries are more likely to have their own external debt when they have fewer growth options and higher cash flow than the rest of the firm. Finally, I find that subsidiary debt mitigates the “corporate socialism” and “poaching” problems modeled in theories of internal capital markets.     

Contagion,decoupling and the spillover effects of the US financial crisis: Evidence from the BRIC markets

Even though the global contagion effects of the financial crisis have been well documented, the transmission mechanism as well as the nature of the volatility spillovers among the US, the EU and the BRIC markets has not been systematically investigated. To examine the dynamic linear and nonlinear causal linkages a stepwise filtering methodology is introduced, for which vector autoregressions and various multivariate GARCH representations are adopted. The sample covers the after-Euro period and includes the financial crisis and the Eurozone debt crisis. The empirical results show that the BRICs have become more internationally integrated after the US financial crisis and contagion is further substantiated. Moreover, no consistent evidence in support of the “decoupling” view is found. Some nonlinear causal links persist after filtering during the examined period. This indicates that nonlinear causality can, to a large extent, be explained by simple volatility effects, although tail dependency and higher-moments may be significant factors of the remaining interdependencies.     

A comment on De Grauwe's, “The legacy of the Eurozone crisis and how to overcome it”

De Grauwe (2016) argues that it has been the asymmetric economic policies of the European Commission where credit nations have benefited at the expense of debtor nations that have fueled the Euro Crisis. In this short comment I provide an alternative explanation for the amplification and persistence experienced by the Eurozone economy during the double-dip recessions of 2008 to 2009 and 2011 to 2013. The Euro crisis can be traced back to contractionary monetary policies made by the European Central Bank at a time when the Eurozone required expansionary monetary policy.     

Target loans, current account balances and capital flows: the ECB’s rescue facility

This paper presents the first comprehensive Target database of the Eurozone and interprets it from an economic perspective. We show that the Target accounts measure the intra-Eurozone balances of payments and indirectly also international credit given through the Eurosystem in terms of reallocating the ECB’s net refinancing credit. We argue that the Euro crisis is a balance-of-payments crisis similar to the Bretton Woods crisis, and document to what extent the Target credit financed the current account deficits and outright capital flight in Greece, Ireland, Portugal, Spain and Italy. To prevent the ECB from undermining the allocative role of the capital market, we propose adopting the US system of credit redemption between the District Feds.
