Cross-border Interbank Networks, Banking Risk and Contagion

Journal of Financial Stability,

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.

Financial Stability and Central Bank Governance

International Journal of Central Banking,
Nr. 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.

Should I Stay or Should I Go? Bank Productivity and Internationalization Decisions

Abstract
Differences in firm-level productivity explain international activities of non-financial firms quite well. We test whether differences in bank productivity determine international activities of banks. Based on a dataset that allows tracking banks across countries and across different modes of foreign entry, we model the ordered probability of maintaining a commercial presence abroad and the volume of banks’ international assets empirically. Our research has three main findings. First, more productive banks are more likely to enter foreign markets in increasingly complex modes. Second, more productive banks also hold larger volumes of foreign assets. Third, higher risk aversion renders entry less likely, but it increases the volume of foreign activities conditional upon entry.

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.

Changing Forces of Gravity: How the Crisis Affected International Banking
Claudia M. Buch, Katja Neugebauer, Christoph Schröder
ZEW Discussion Paper, No. 14-006,
2014
Abstract
The global financial crisis has brought to an end a rather unprecedented period of banks’ international expansion. We analyze the effects of the crisis on international banking. Using a detailed dataset on the international assets of all German banks with foreign affiliates for the years 2002-2011, we study bank internationalization before and during the crisis. Our data allow analyzing not only the international assets of the banks’ headquarters but also of their foreign affiliates. We show that banks have lowered their international assets, both along the extensive and the intensive margin. This withdrawal from foreign markets is the result of changing market conditions, of policy interventions, and of a weakly increasing sensitivity of banks to financial frictions.

Abstract
Am 2. und 3. Dezember 2013 fand am IWH in Zusammenarbeit mit dem Centre interuniversitaire de recherche en économie quantitative (CIREQ), Montréal, und der Martin-Luther-Universität Halle-Wittenberg der 14. IWH-CIREQ Macroeconometric Workshop statt. Im Rahmen des Workshops stellten Wissenschaftler und Wissenschaftlerinnen europäischer Universiäten und internationaler Organisationen, wie z. B. der Europäischen Zentralbank und der Europäischen Kommission sowie der spanischen, kanadischen und japanischen Zentralbanken, ihre neuesten Forschungsergebnisse im Bereich makroökonometrischer Modellierung und Prognose unter Berücksichtigung großer und komplexer Datenbanken vor. Auch wurden weitere makroökonomische Themen wie beispielsweise die Wirkung geldpolitischer Schocks oder Wechselkurs-Volatilitäten diskutiert.

Sovereign Credit Risk, Banks' Government Support, and Bank Stock Returns around the World: Discussion of Correa, Lee, Sapriza, and Suarez

Abstract
In the years leading up to the 2008–09 financial crisis, many banks around the world greatly expanded their balance sheets to take advantage of cheap and abundantly available funding. Access to international funding markets, in particular, made it possible for banks to reach a size that in some cases was a large multiple of their home countries’ gross domestic product (GDP). In Iceland, for example, assets of the banking system reached up to 900% of GDP in 2007. Similarly, by the end of 2008, assets in UK and Swiss banks exceeded 500% of their countries’ GDPs, respectively. Banks may also have grown rapidly because they may have wanted to reach too-big-to-fail status in their country, implying even lower funding cost (Penas and Unal 2004).
The depth and severity of the 2008–09 financial crisis and the subsequent debt crisis in Europe, however, have cast doubts on the ability of governments to bail out banks when they experience severe difficulties, in particular, in financially fragile environments and faced with large budget imbalances. This has resulted in as what some observers have dubbed a “doom loop”: the combination of weak public finances and weak banks results in a vicious cycle, in which the funding cost of banks increases, as the ability of governments to bail out banks is called into question, in turn increasing the funding cost of these banks and making the likelihood that the government will actually have to step in even higher, which in turn increases funding cost to the government and so forth.
Against this background, the paper by Correa et al. (2014) explores the link between sovereign rating changes and bank stock returns. They show large negative reactions of stock returns in response to sovereign ratings downgrades for banks that are expected to receive government support in case of failure. They find the strongest effects in developed economies, where the credibility of government bail outs is higher ex ante, while the effects are smaller in developing and emerging economies. In my view, the paper makes a number of important contributions to the extant literature.
