Cross-border Interbank Networks, Banking Risk and Contagion

Journal of Financial Stability,
2015
Abstract
Recent events have highlighted the role of cross-border linkages between banking systems in transmitting local developments across national borders. This paper analyzes whether international linkages in interbank markets affect the stability of interconnected banking systems and channel financial distress within a network consisting of banking systems of the main advanced countries for the period 1994–2012. Methodologically, I use a spatial modeling approach to test for spillovers in cross-border interbank markets. The results suggest that foreign exposures in banking play a significant role in channeling banking risk: I find that countries that are linked through foreign borrowing or lending positions to more stable banking systems abroad are significantly affected by positive spillover effects. From a policy point of view, this implies that in stable times, linkages in the banking system can be beneficial, while they have to be taken with caution in times of financial turmoil affecting the whole system.

Risk and Return - Is there an Unholy Cycle of Ratings and Yields?
Makram El-Shagi, Gregor von Schweinitz
Economics Letters,
2015
Abstract
After every major financial crisis, the question about the responsibility of the rating agencies resurfaces. Regarding government bonds, the most frequently voiced concern targeted “unreasonably” bad ratings that might trigger capital flights and increasing risk premia which sanction further rating downgrades. In this paper we develop a multivariate, nonparametric version of the Pesaran type cointegration model that allows for nonlinearities, to show that a unique equilibrium between ratings and sovereign yields exists. Therefore, we have to reject the concern that there is an unholy cycle leading to certain default in the long run.

Do We Need New Modelling Approaches in Macroeconomics?

Financial Cycles and the Real Economy: Lessons for CESEE Countries,
2014
Abstract
The economic and financial crisis that emerged in 2008 also initiated an intense discussion on macroeconomic research and the role of economists in society. The debate focuses on three main issues. Firstly, it is argued that economists failed to predict the crisis and to design early warning systems. Secondly, it is claimed that economists use models of the macroeconomy which fail to integrate financial markets and which are inadequate to model large economic crises. Thirdly, the issue has been raised that economists invoke unrealistic assumptions concerning human behaviour by assuming that all agents are self-centred, rationally optimizing individuals. In this paper, we focus on the first two issues. Overall, our thrust is that the above statements are a caricature of modern economic theory and empirics. A rich field of research developed already before the crisis and picked up shortcomings of previous models.

Linking Distress of Financial Institutions to Macrofinancial Shocks

ECB Working Paper,
No. 1749,
2014
Abstract
This paper links granular data of financial institutions to global macroeconomic variables using an infinite-dimensional vector autoregressive (IVAR) model framework. The approach taken allows for an assessment of the two-way links between the financial system and the macroeconomy, while accounting for heterogeneity among financial institutions and the role of international linkages in the transmission of shocks. The model is estimated using macroeconomic data for 21 countries and default probability estimates for 35 euro area financial institutions. This framework is used to assess the impact of foreign macroeconomic shocks on default risks of euro area financial firms. In addition, spillover effects of firm-specific shocks are investigated. The model captures the important role of international linkages, showing that economic shocks in the US can generate a rise in the default probabilities of euro area firms that are of a significant magnitude compared to recent historical episodes such as the financial crisis. Moreover, the potential heterogeneity across financial firms.

Financial Stability and Central Bank Governance

International Journal of Central Banking,
No. 4,
2014
Abstract
The financial crisis has ignited a debate about the appropriate objectives and the governance structure of Central Banks. We use novel survey data to investigate the relation between these traits and banking system stability focusing in particular on their role in micro-prudential supervision. We find that the separation of powers between single and multiple bank supervisors cannot explain credit risk prior or during the financial crisis. Similarly, a large number of Central Bank governance traits do not correlate with system fragility. Only the objective of currency stability exhibits a significant relation with non-performing loan levels in the run-up to the crisis. This effect is amplified for those countries with most frequent exposure to IMF missions in the past. Our results suggest that the current policy discussion whether to centralize prudential supervision under the Central Bank and the ensuing institutional changes some countries are enacting may not produce the improvements authorities are aiming at. Whether other potential improvements in prudential supervision due to, for example, external disciplinary devices, such as IMF conditional lending schemes, are better suited to increase financial stability requires further research.

Taxes, Banks and Financial Stability
Reint E. Gropp
R. de Mooij and G. Nicodème (eds), Taxation and Regulation of the Financial Sector. MIT Press,
2014
Abstract
In response to the financial crisis of 2008/2009, numerous new taxes on financial institutions have been discussed or implemented around the world. This paper discusses the connection between the incidence of the taxes, their incentive effects, and policy makers’ objectives. Combining basic insights from banking theory with standard models of tax incidence shows that the incidence of such taxes will disproportionately fall on small and medium size enterprises. The arguments presented suggest it is unlikely that the taxes will have a beneficial impact on financial stability or raise significant amounts of revenue without increasing the cost of capital to bank dependent firms significantly.

The Euro Plus Pact: Cost Competitiveness and External Capital Flows in the EU Countries
Hubert Gabrisch, K. Staehr
Abstract
The Euro Plus Pact was approved by 23 EU countries in March 2011 and came into force shortly afterwards. The Pact stipulates a range of quantitative targets meant to strengthen cost competitiveness with the aim of preventing the accumulation of external financial imbalances. This paper uses Granger causality tests and vector autoregressive models to assess the short-term linkages between changes in the relative unit labour cost and changes in the current account balance. The sample consists of annual data for 27 EU countries for the period 1995-2012. The main finding is that changes in the current account balance precedes changes in relative unit labour costs, while there is no discernible effect in the opposite direction. The divergence in unit labour costs between the countries in Northern Europe and the countries in Southern and Eastern Europe may thus partly be the result of capital flows from the core of Europe to the periphery prior to the global financial crisis. The results also suggest that the measures in the Euro Plus Pact to restrain the growth of unit labour costs may not affect the current account balance in the short term.

Konjunktur aktuell: Deutsche Konjunktur hat Schwung verloren
Konjunktur aktuell,
No. 4,
2014
Abstract
Die deutsche Wirtschaft expandiert im Jahr 2014 in mäßigem Tempo. Der hohe Produktionszuwachs vom Jahresanfang hat sich nicht fortgesetzt, und die Unternehmen schätzen ihre Aussichten nicht mehr ganz so günstig ein, denn eine kräftige Erholung des Euroraums lässt weiter auf sich warten. Zudem verunsichert der Konflikt zwischen Russland und dem Westen. Die binnenwirtschaftlichen Bedingungen sind aber weiter günstig. Das reale Bruttoinlandsprodukt dürfte im Jahr 2014 um 1,5% und im Jahr 2015 um 1,6% zunehmen.

Abstract
Deutschland befindet sich in einem binnenwirtschaftlich getragenen Aufschwung, der auch durch verstärkte Investitionstätigkeit Schub erhält. Die Absatzperspektiven der Unternehmen sind gut, und die privaten Haushalte dürften ihre Konsumausgaben aufgrund der guten Beschäftigungslage ausweiten. Aus dem Ausland kommen dagegen nur geringe Impulse. Das Bruttoinlandsprodukt dürfte im Jahr 2014 um 2,0% steigen

Abstract
Die Globalisierung von Finanzmärkten hat in den letzten Jahren stetig zugenommen. Gründe dafür sind gesteigerte Auslandsaktivitäten realwirtschaftlicher Unternehmen, die Einführung einer gemeinsamen Währung im Euroraum sowie die Deregulierung der Finanzmärkte. Ein Indikator für das Zusammenwachsen von Finanzmärkten sind zum Beispiel die drastisch gestiegenen Auslandsaktivitäten deutscher und französischer Banken. Diese internationalen Verflechtungen können einerseits positive Auswirkungen haben: Kapital kann dorthin fließen, wo es gebraucht wird, und Risiken können über nationale Grenzen hinweg gestreut werden. Andererseits können grenzüberschreitende Aktivitäten im Finanzsektor Ansteckungseffekte verursachen, indem sie Schocks international übertragen.
