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.

Kommentar: Manövriert sich die EZB in eine Falle?

Nr. 1,

Abstract
Die EZB hat am 22. Januar 2015 beschlossen, in großem Umfang Anleihen öffentlicher Institutionen aus dem Euroraum, darunter auch der Nationalstaaten, zu kaufen. Es gibt gute Gründe für diese Maßnahme: Marktbasierte mittelfristige Inflationserwartungen sind zuletzt deutlich gesunken, die Inflationsrate ist tendenziell rückläufig und war zuletzt sogar negativ. Die Wahrscheinlichkeit einer deflationären Spirale hat sich erhöht, mit unabsehbaren Folgen für die wirtschaftliche Entwicklung. Die schwache Verbraucherpreisentwicklung im Euroraum basiert auf mehreren Faktoren: der schleppenden Konjunkturentwicklung, fallenden Ölpreisen und fiskalpolitischer Konsolidierung in einigen Euroländern (Spanien, Portugal, Irland).

EZB-Staatsanleihekäufe: Langfristig sehr riskant – aber angesichts der akuten Gefahren für die Preisstabilität vertretbar
Die Europäische Zentralbank hat sich für den Kauf von Staatsanleihen in großem Umfang entschieden. Durch den damit verbundenen Rückgang der Umlaufsrendite von Staatsanleihen ist es wahrscheinlich, dass auch die Unternehmenszinsen gesenkt werden können. Dadurch würden mehr realwirtschaftliche Projekte rentabel und die Unternehmensinvestitionen zunehmen. Käufe von Staatsanleihen durch die Notenbank bringen zwar erhebliche Risiken mit sich, sind aber mit Blick auf die akuten Gefahren für die Geldpolitik vertretbar.

Financial Integration, Housing, and Economic Volatility
Elena Loutskina, Philip E. Strahan
Journal of Financial Economics,
Nr. 1,
2015
Abstract
The Great Recession illustrates the sensitivity of the economy to housing. This paper shows that financial integration, fostered by securitization and nationwide branching, amplified the positive effect of housing price shocks on the economy during the 1994–2006 period. We exploit variation in credit supply subsidies across local markets from government-sponsored enterprises to measure housing price changes unrelated to fundamentals. Using this instrument, we find that house price shocks spur economic growth. The effect is larger in localities more financially integrated, through both secondary loan market and bank branch networks. Financial integration thus raised the effect of collateral shocks on local economies, increasing economic volatility.

Switching to Exchange Rate Flexibility? The Case of Central and Eastern European Inflation Targeters
Andrej Drygalla
FIW Working Paper,
Nr. 139,
2015
Abstract
This paper analyzes changes in the monetary policy in the Czech Republic, Hungary, and Poland following the policy shift from exchange rate targeting to inflation targeting around the turn of the millennium. Applying a Markovswitching dynamic stochastic general equilibrium model, switches in the policy parameters and the volatilities of shocks hitting the economies are estimated and quantified. Results indicate the presence of regimes of weak and strong responses of the central banks to exchange rate movements as well as periods of high and low volatility. Whereas all three economies switched to a less volatile regime over time, findings on changes in the policy parameters reveal a lower reaction to exchange rate movements in the Czech Republic and Poland, but an increased attention to it in Hungary. Simulations for the Czech Republic and Poland also suggest their respective central banks, rather than a sound macroeconomic environment, being accountable for reducing volatility in variables like inflation and output. In Hungary, their favorable developments can be attributed to a larger extent to the reduction in the size of external disturbances.

Financial Stability and Central Bank Governance

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.

Taxes, Banks and Financial Stability

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.

Abstract
Die Zinsspanne ist die Differenz zwischen den Soll- und Habenzinsen. Dies sind also die Zinserträge, welche Banken für Anlagen, z. B. Kredite, relativ zu den Zinsaufwendungen erzielen können, welche sie für ihre eigene Refinanzierung, z. B. in Form von Einlagen, aufwenden müssen.

The Dynamics of Bank Spreads and Financial Structure
Reint E. Gropp, Christoffer Kok, J.-D. Lichtenberger
Quarterly Journal of Finance,
Nr. 4,
2014
Abstract
This paper investigates the effect of within banking sector competition and competition from financial markets on the dynamics of the transmission from monetary policy rates to retail bank interest rates in the euro area. We use a new dataset that permits analysis for disaggregated bank products. Using a difference-in-difference approach, we test whether development of financial markets and financial innovation speed up the pass through. We find that more developed markets for equity and corporate bonds result in a faster pass-through for those retail bank products directly competing with these markets. More developed markets for securitized assets and for interest rate derivatives also speed up the transmission. Further, we find relatively strong effects of competition within the banking sector across two different measures of competition. Overall, the evidence supports the idea that developed financial markets and competitive banking systems increase the effectiveness of monetary policy.
