Macroprudential Policy and Intra-group Dynamics: The Effects of Reserve Requirements in Brazil
Chris Becker, Matias Ossandon Busch, Lena Tonzer
Abstract
This paper examines whether intra-group dynamics matter for the transmission of macroprudential policy. Using novel bank-level data on the Brazilian banking system, we investigate the effect of reserve requirements targeting headquarter banks’ deposit share on credit supply by their municipal bank branches. For identification purposes, we exploit that reserve requirements are adjusted following global economic cycles. Our results reveal a lending channel of reserve requirements for branches whose parent banks are more exposed to targeted deposits. Branch ownership and exposure to internal liquidity are central in explaining the results. Our findings reveal limitations in current macroprudential policy frameworks.

Central Bank Transparency and Cross-border Banking
Stefan Eichler, Helge Littke, Lena Tonzer
Journal of International Money and Finance,
2017
Abstract
We analyze the effect of central bank transparency on cross-border bank activities. Based on a panel gravity model for cross-border bank claims for 21 home and 47 destination countries from 1998 to 2010, we find strong empirical evidence that a rise in central bank transparency in the destination country, on average, increases cross-border claims. Using interaction models, we find that the positive effect of central bank transparency on cross-border claims is only significant if the central bank is politically independent and operates in a stable economic environment. Central bank transparency and credibility are thus considered complements by banks investing abroad.

Do Conventional Monetary Policy Instruments Matter in Unconventional Times?
Manuel Buchholz, Kirsten Schmidt, Lena Tonzer
Abstract
This paper investigates how declines in the deposit facility rate set by the European Central Bank (ECB) affect bank behavior. The ECB aims to reduce banks’ incentives to hold reserves at the central bank and thus to encourage loan supply. However, given depressed margins in a low interest environment, banks might reallocate their liquidity toward more profitable liquid assets other than traditional loans. Our analysis is based on a sample of euro area banks for the period from 2009 to 2014. Three key findings arise. First, banks reduce their reserve holdings following declines in the deposit facility rate. Second, this effect is heterogeneous across banks depending on their business model. Banks with a more interest-sensitive business model are more responsive to changes in the deposit facility rate. Third, there is evidence of a reallocation of liquidity toward loans but not toward other liquid assets. This result is most pronounced for non-GIIPS countries of the euro area.

Drivers of Systemic Risk: Do National and European Perspectives Differ?
Claudia M. Buch, Thomas Krause, Lena Tonzer
Abstract
In Europe, the financial stability mandate generally rests at the national level. But there is an important exception. Since the establishment of the Banking Union in 2014, the European Central Bank (ECB) can impose stricter regulations than the national regulator. The precondition is that the ECB identifies systemic risks which are not adequately addressed by the macroprudential regulator at the national level. In this paper, we ask whether the drivers of systemic risk differ when applying a national versus a European perspective. We use market data for 80 listed euro-area banks to measure each bank’s contribution to systemic risk (SRISK) at the national and the euro-area level. Our research delivers three main findings. First, on average, systemic risk increased during the financial crisis. The difference between systemic risk at the national and the euro-area level is not very large, but there is considerable heterogeneity across countries and banks. Second, an exploration of the drivers of systemic risk shows that a bank’s contribution to systemic risk is positively related to its size and profitability. It decreases in a bank’s share of loans to total assets. Third, the qualitative determinants of systemic risk are similar at the national and euro-area level, whereas the quantitative importance of some determinants differs.

On the Nonexclusivity of Loan Contracts: An Empirical Investigation
Hans Degryse, Vasso Ioannidou, Erik von Schedvin
Management Science,
Nr. 12,
2016
Abstract
We study how a bank's willingness to lend to a previously exclusive firm changes once the firm obtains a loan from another bank ("outside loan") and breaks an exclusive relationship. Using a difference-in-difference analysis and a setting where outside loans are observable, we document that an outside loan triggers a decrease in the initial bank's willingness to lend to the firm, i.e., outside loans are strategic substitutes. Consistent with concerns about coordination problems and higher indebtedness, we find that this reaction is more pronounced the larger the outside loan and it is muted if the initial bank's existing and future loans retain seniority and are protected with valuable collateral. Our results give a benevolent role to transparency enabling banks to mitigate adverse effects from outside loans. The resulting substitute behavior may also act as a stabilizing force in credit markets limiting positive comovements between lenders, decreasing the possibility of credit freezes and financial crises.

Taxing Banks: An Evaluation of the German Bank Levy
Claudia M. Buch, Björn Hilberg, Lena Tonzer
Journal of Banking and Finance,

2016
Abstract
Bank distress can have severe negative consequences for the stability of the financial system. Regimes for the restructuring and resolution of banks, financed by bank levies, aim at reducing these costs. This paper evaluates the German bank levy, which has been implemented since 2011. Our analysis offers three main insights. First, revenues raised through the levy were lower than expected. Second, the bulk of the payments were contributed by large commercial banks and by the central institutions of savings banks and credit unions. Third, for those banks, which were affected by the levy, we find evidence for a reduction in lending and higher deposit rates.

Monetary-fiscal Policy Interaction and Fiscal Inflation: A Tale of Three Countries
Martin Kliem, Alexander Kriwoluzky, Samad Sarferaz
European Economic Review,
2016
Abstract
We study the impact of the interaction between fiscal and monetary policy on the low-frequency relationship between the fiscal stance and inflation using cross-country data from 1965 to 1999. In a first step, we contrast the monetary–fiscal narrative for Germany, the U.S., and Italy with evidence obtained from simple regression models and a time-varying VAR. We find that the low-frequency relationship between the fiscal stance and inflation is low during periods of an independent central bank and responsible fiscal policy and more pronounced in times of non-responsible fiscal policy and accommodative monetary authorities. In a second step, we use an estimated DSGE model to interpret the low-frequency measure structurally and to illustrate the mechanisms through which fiscal actions affect inflation in the long run. The findings from the DSGE model suggest that switches in the monetary–fiscal policy interaction and accompanying variations in the propagation of structural shocks can well account for changes in the low-frequency relationship between the fiscal stance and inflation.
