The stability of short-term interest rates pass-through in the euro area during the financial market and sovereign debt crises

We analyse the dynamics of the pass-through of banks’ marginal cost to bank lending rates over the 2008 crisis and the euro area sovereign debt crisis in France, Germany, Greece, Italy, Portugal and Spain. We measure banks’ marginal cost by their rate on new deposits, contrary to the literature that focuses on money market rates. This allows us to account for banks’ risks. We focus on the interest rate on new short-term loans granted to non-financial corporations in these countries. Our analysis is based on an error-correction approach that we extend to handle the time-varying long-run relationship between banks’ lending rates and banks’ marginal cost, as well as stochastic volatility. Our application is based on a harmonised monthly database from January 2003 to October 2014. We estimate the model within a Bayesian framework, using Markov Chain Monte Carlo methods (MCMC).We reject the view that the transmission mechanism is permanent over time. The long-run relationship moved with the sovereign debt crises to a new one, with a slower pass-through and higher bank lending rates. Its developments are heterogeneous from one country to the other. Impediments to the transmission of monetary rates depend on the heterogeneity in banks marginal costs and therefore, its risks. We also find that rates to small firms increase compared to large firms in a few countries. Using a VAR model, we show that overall, the effect of a shock on the rate of new deposits on the unexpected variances of new loans has been less important since 2010. These results confirm the slowdown in the transmission mechanism.     

The euro area sovereign debt crisis: Identifying flight-to-liquidity and the spillover mechanisms

Looking at the daily period between January 2006 and December 2012, besides the traditional credit and liquidity risks, which explain the developments of sovereign yields relative to the Bund for Greece, Ireland, Portugal, Spain and Italy, two additional factors have played a key role in the developments of euro area sovereign yield spreads: flight to liquidity benefiting the German Bund and the spillover effect from Greece. The flight to liquidity premium, which is estimated by constructing the spread between a German state guaranteed agency bond and the Bund, is behind the pricing of all euro area spreads and, specifically, is the only factor explaining the sovereign spreads for Finland and the Netherlands. The spillover effect from Greece, which is identified using complementary approaches, has contributed to developments in spreads of countries with weaker fiscal fundamentals, a lower degree of competitiveness and a higher need of foreign financing. However, a large fraction of the spillover across countries remains unexplained.     

The interest rate pass-through in the Euro area during the global financial crisis

This paper uses panel vector autoregressive (VAR) models for euro area member countries to explore the widening of retail bank interest rate spreads that emerged in the course of the global financial crisis. We find that the interest rate pass-through was generally complete on impact before the outbreak of the financial crisis, but became significantly distorted in the period thereafter, which hampered the effectiveness of monetary policy. Empirical evidence suggests that the decrease in the interest rate pass-through can be related to a change in the structural parameters characterizing the economies and a substantial increase in the average size of structural shocks. DSGE model simulations show that an increase in the frictions that banks are subject to can explain the decrease in the retail bank interest rate pass-through.     

Contagion during the Greek sovereign debt crisis

We examine the impact of news about Greece and news about a Greek bailout on bank stock prices in 2010 using data for 48 European banks. We identify the twenty days with extreme returns on Greek sovereign bonds and categorise the news events during those days into news about Greece and news about the prospects of a Greek bailout. We find that, except for Greek banks, news about Greece does not lead to abnormal returns while news about a bailout does, even for banks without any exposure to Greece or other highly indebted euro countries. This finding suggests that markets consider news about the bailout to be a signal of European governments' willingness in general to use public funds to combat the financial crisis. Sovereign bond prices of Portugal, Ireland, and Spain respond to both news about Greece and news about a Greek bailout.     

Crash risk of the euro in the sovereign debt crisis of 2009–2010

The economic-political instability of a country, which is tied to its credit risk, often leads to sharp depreciation and heightened volatility in its currency. This paper shows that not only the creditworthiness of the euro-area countries with weaker fiscal positions but also that of the member countries with more sound fiscal positions are important determinants of the deep out-of-the-money euro put option prices, which embedded information on the euro crash risk during the sovereign debt crisis of 2009–2010. We also find evidence of information flow from the sovereign credit default swap market to the currency option market during the crisis.

Disentangling contagion among sovereign CDS spreads during the European debt crisis

During the last crisis, developed economies' sovereign credit default swap (hereafter CDS) premia have gained in importance as a tool for approximating credit risk. In this paper, we fit a dynamic factor model to decompose the sovereign CDS spreads of ten OECD economies into three components: a common factor, a second factor driven by European peripheral countries and an idiosyncratic component. We use this decomposition to propose a novel methodology based on the real-time estimates of the model to characterize contagion among the ten series. Our procedure allows the country that triggers contagion in each period, which can be any peripheral economy, to be disentangled. According to our findings, since the onset of the sovereign debt crisis, contagion has played a non-negligible role in the European peripheral countries, which confirms the existence of significant financial linkages between these economies.     

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.     

Bank/sovereign risk spillovers in the European debt crisis

This paper investigates contagion between bank and sovereign default risk in Europe over the period 2007–2012. We define contagion as excess correlation, i.e. correlation between banks and sovereigns over and above what is explained by common factors, using CDS spreads at the bank and at the sovereign level. Moreover, we investigate the determinants of contagion by analyzing bank-specific as well as country-specific variables and their interaction. Using the EBA’s disclosure of sovereign exposures of banks, we provide empirical evidence that three contagion channels are at work: a guarantee channel, an asset holdings channel and a collateral channel. We find that banks with a weak capital buffer, a weak funding structure and less traditional banking activities are particularly vulnerable to risk spillovers. At the country level, the debt ratio is the most important driver of contagion. Furthermore, the impact of government interventions on contagion depends on the type of intervention, with outright capital injections being the most effective measure in reducing spillover intensity.     

Accrual mispricing: Evidence from European sovereign debt crisis

PurposeThis paper examines the accrual anomaly on the European market and the impact of the financial crisis on its dynamics.Design/methodology/approachUsing a sample of public European firms, during the period 2005-2016, this paper follows Sloan (1996) seminal work and measures accruals as Dechow, Sloan and Sweeney (1995).FindingsThere is no evidence that accrual anomaly persists on European markets. The study shows that, contrary to previous research, investors are not underweighting the accrual component of earnings and that accruals are not a good predictor of future stock returns.Research limitations/implicationsOur study has two limitations. First, due to the lack of data, the original sample was reduced to about one third. Second, results must be interpreted carefully since the sample period may be seen as an outlier case attributed to the crisis. Research on future years may unveil a conclusion on this.Practical implicationsResults suggest that transaction costs and idiosyncratic risk are no longer a barrier to investors. Results also point toward a possible new outcome in investor´s behaviour during crisis. Economically, given the lower returns that can be obtained on today markets, it makes sense that investors may reduce their risk aversion levels to get more returns.Originality/valueThis study contributes to the ongoing debate about accruals anomaly and market efficiency. To the best of our knowledge, it provides an original contribution to the literature by framing the accrual anomaly during the European debt crisis.     

The impact of the sovereign debt crisis on the activity of Italian banks

We examine the implications of the sovereign debt tensions on the Italian credit market by estimating the effect of the 10-year BTP-Bund spread on a wide array of bank interest rates, categories of loans and income statement variables. We exploit the heterogeneity between large and small intermediaries to assess to what extent the transmission of sovereign risk differed in relation with different banks’ balance-sheet characteristics and business strategies. Regarding the cost of funding, we find that changes in the BTP-Bund spread have a sizeable effect on the interest rates on term deposits and newly issued bonds but virtually no effect on overnight deposits. Furthermore, the sovereign spread significantly affects the cost of credit for firms and households and exerts a negative effect on loan growth. All these results are magnified when considering alone the five largest banks, which are typically less capitalized, have a larger funding gap and incidence of bad loans and rely more on non-traditional banking activities. Sovereign tensions also affect the main items of banks’ income statement.     

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.     

Price effects of sovereign debt auctions in the euro-zone: The role of the crisis

We show that new public debt issues cause an auction cycle for Italian secondary-market debt, but not for German debt. The cycle is mainly observed for the crisis period since mid-2007 and is larger when the crisis, as measured by yield volatility and CDS spreads of primary dealers, is more intense. Volatility seems to be the main driving factor. The cycle is also present in secondary-market series with maturities close to the auctioned series. Our findings are consistent with the theory of primary dealers’ limited risk-bearing capacity. There is also weak evidence of spill-overs from foreign auctions to domestic markets.     

希腊主权债务危机的成因与影响

日益严重的希腊主权债务危机将希腊推向了欧元区主权债务问题的风口浪尖,由此也形成了影响欧元区稳定运行的严峻挑战。该文基于国际金融危机对希腊经济与财政运行状况的影响,分析了引起希腊主权债务危机的成因及解决途径,指出解决希腊主权债务危机除了希腊自身的努力外,依然需要国际社会尤其是欧盟的援助。从全球的角度看,其他经济体的主权债务问题也同样值得警惕和重视。     

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。     

An asymmetric dynamic conditional correlation analysis of linkages of European financial institutions during the Greek sovereign debt crisis

This article employs the asymmetric dynamic conditional correlation (DCC) model to assess impacts of the recent sovereign debt crisis on the time-varying correlations of five European financial institutions holding large amounts of Greek sovereign bonds (National Bank of Greece, BNP Paribas, Dexia, Generali, and Commerzbank). Contrary to the results of preceding studies, we find significant increases in the correlations between several combinations of the financial institutions’ stock returns after the inception of the sovereign debt crisis, indicating contagion effects. Moreover, our findings show that the parameter of the standardized negative residuals is statistically significant in the case of DCC estimates between two specific institutions. This suggests that the conditional correlation of stock returns between the two institutions is more significantly influenced by negative shocks than by positive innovations to return.     

Alpha-CIR model with branching processes in sovereign interest rate modeling

We introduce a class of interest rate models, called the \(\alpha\)-CIR model, which is a natural extension of the standard CIR model by adding a jump part driven by \(\alpha\)-stable Lévy processes with index \(\alpha\in(1,2]\). We deduce an explicit expression for the bond price by using the fact that the model belongs to the family of CBI and affine processes, and analyze the bond price and bond yield behaviors. The \(\alpha\)-CIR model allows us to describe in a unified and parsimonious way several recent observations on the sovereign bond market such as the persistency of low interest rates together with the presence of large jumps. Finally, we provide a thorough analysis of the jumps, and in particular the large jumps.     

The systemic risk of European banks during the financial and sovereign debt crises

European banks became a source of risk to global financial markets during the financial crisis and attention to the European banking sector increased during the sovereign debt crisis. To measure the systemic risk of European banks, we calculate a distress insurance premium (DIP), which integrates the characteristics of bank size, probability of default, and correlation. Based on this measure, the systemic risk of European banks reached its height in late 2011 around €500 billion. We find that this was largely due to sovereign default risk. The DIP methodology is also used to measure the systemic contribution of individual banks. This approach identifies the large systemically important European banks, but Italian and Spanish banks as a group notably increased in systemic importance during the sample period. Bank-specific fundamentals like capital-asset ratios predict the one-year-ahead systemic risk contributions.     

The management of interest rate risk during the crisis: Evidence from Italian banks

We use a unique dataset to analyze how Italian banking groups managed their exposure to interest rate risk during the recent financial crisis. First of all, we document that on average the interest rate risk exposure – measured by duration gap approach – has been limited and well below the alert level enforced by regulators. Second, our econometric results indicate a relation of substitutability between banks’ on-balance-sheet interest rate risk and their use of interest rate derivatives suggesting that banks used these two instruments to curb their overall interest rate risk exposure in case of an increase in interest rates. Furthermore, we also find robust evidence of a negative correlation between banks’ interest rate risk and liquidity risk.
