Crises, rescues, and policy transmission through international banks
Claudia M. Buch
Bundesbank Discussion Paper 15/2011,
2011
Abstract
The World Financial Crisis has shaken the fundamentals of international banking
and triggered a downward spiral of asset prices. To prevent a further meltdown of
markets, governments have intervened massively through rescues measures aimed at recapitalizing banks and through liquidity support. We use a detailed, banklevel dataset for German banks to analyze how the lending and borrowing of their foreign affiliates has responded to domestic (German) and to US crisis support schemes. We analyze how these policy interventions have spilled over into
foreign markets. We identify loan supply shocks by exploiting that not all banks
have received policy support and that the timing of receiving support measures
has differed across banks. We find that banks covered by rescue measures of the
German government have increased their foreign activities after these policy
interventions, but they have not expanded relative to banks not receiving support.
Banks claiming liquidity support under the Term Auction Facility (TAF) program
have withdrawn from foreign markets outside the US, but they have expanded
relative to affiliates of other German banks.

Size, Productivity, and International Banking
Claudia M. Buch, C. T. Koch, Michael Koetter
Journal of International Economics,
No. 2,
2011
Abstract
Heterogeneity in size and productivity is central to models that explain which manufacturing firms export. This study presents descriptive evidence on similar heterogeneity among international banks as financial services providers. A novel and detailed bank-level data set reveals the volume and mode of international activities for all German banks. Only a few, large banks have a commercial presence abroad, consistent with the size pecking order documented for manufacturing firms. However, the relationship between internationalization and productivity also yields two inconsistencies with recent trade models. First, virtually all banks hold at least some foreign assets, irrespective of size or productivity. Second, some fairly unproductive banks maintain commercial presences abroad.

Stock Market-Induced Currency Crises: A New Type of Twins
Stefan Eichler, Dominik Maltritz
Review of Development Economics,
No. 2,
2011
Abstract
This paper explores the link between currency crises and the stock market in emerging economies. By integrating foreign stock market investors in a currency crisis model, we reveal a new fundamental inconsistency as a potential crisis trigger: since emerging economies' stock markets often have high returns, whereas central bank reserves grow slowly or decline, the amount of reserves foreign investors can deplete when selling their stocks and repatriating the proceeds grows over time and is considerably higher than funds that have been invested in the stock market. Capital withdrawals of foreign stock market investors can trigger currency crises by depleting central bank reserves, particularly in successful countries with booming stock markets and large foreign investment.

Central and Eastern European Countries in the Global Financial Crisis: A Typical Twin Crisis?
Diemo Dietrich, Tobias Knedlik, Axel Lindner
Post-Communist Economies,
No. 4,
2011
Abstract
This paper shows that during the Great Recession, banking and currency crises occurred simultaneously in Central and Eastern Europe. Events, however, differed widely from what happened during the Asian crisis that usually serves as the model case for the concept of twin crises. We look at three elements that help explaining the nature of events in Central and Eastern Europe: the problem of currency mismatches, the relation between currency and banking crises, and the importance of multinational banks for financial stability. It is shown that theoretical considerations concerning internal capital markets of multinational banks help understand what happened on capital markets and in the financial sector of the region. We discuss opposing effects of multinational banking on financial stability and find that institutional differences are the key to understand differing effects of the global financial crisis. In particular, we argue that it matters if international activities are organized by subsidiaries or by cross-border financial services, how large the share of foreign currency-denominated credit is and whether the exchange rate is fixed or flexible. Based on these three criteria we give an explanation why the pattern of the crisis in the Baltic States differed markedly from that in Poland and the Czech Republic, the two largest countries of the region.

Do Banks Benefit from Internationalization? Revisiting the Market Power-Risk Nexus
Claudia M. Buch, C. T. Koch, Michael Koetter
Abstract
Recent developments on international financial markets have called the benefits of
bank globalization into question. Large, internationally active banks have
acquired substantial market power, and international activities have not
necessarily made banks less risky. Yet, surprisingly little is known about the
actual link between bank internationalization, bank risk, and market power.
Analyzing this link is the purpose of this paper. We jointly estimate the
determinants of risk and market power of banks, and we analyze the effects of
changes in terms of the number of foreign countries (the extensive margin) and
the volume of foreign assets (the intensive margin). Our paper has four main
findings. First, there is a strong negative feedback effect between risk and market
power. Second, banks with higher shares of foreign assets, in particular those held
through foreign branches, have higher market power at home. Third, holding
assets in a large number of foreign countries tends to increase bank risk. Fourth,
the impact of internationalization differs across banks from different banking
groups and of different size.

International Bank Portfolios: Short- and Long-Run Responses to Macroeconomic Conditions
S. Blank, Claudia M. Buch
Review of International Economics,
No. 2,
2010
Abstract
International bank portfolios constitute a large component of international country portfolios. Yet, banks’ response to international macroeconomic conditions remains largely unexplored.We use a novel dataset on banks’ international portfolios to answer three questions. First, what are the long-run determinants of banks’ international portfolios? Second, how do banks’ international portfolios adjust to short-run macroeconomic developments? Third, does the speed of adjustment change with the degree of financial integration?We find that, in the long-run, market size has a positive impact on foreign assets and liabilities. An increase in the interest differential between the home and the foreign economy lowers foreign assets and increases foreign liabilities. Foreign trade has a positive impact on international bank portfolios, which is independent from the effect of other macroeconomic variables. Short-run dynamics show heterogeneity across countries, but these dynamics can partly be explained with gravity-type variables.

Macroeconomic Shocks and Banks' Foreign Assets
Claudia M. Buch, K. Carstensen, A. Schertler
Journal of Money, Credit and Banking,
No. 1,
2010
Abstract
Recent developments in international financial markets have highlighted the role of banks in the transmission of shocks across borders. We employ dynamic panel methods for a sample of OECD countries to analyze whether banks' foreign assets react to macroeconomic shocks at home and abroad. We find that banks reduce their foreign assets in response to a relative increase in domestic interest rates, and they increase their foreign assets when the growth rate of world energy prices rises. The responses are characterized by a temporal overshooting and a dynamic adjustment process that extends over several quarters.

Margins of international banking: Is there a productivity pecking order in banking, too?
Claudia M. Buch
Bundesbank Discussion Paper 12/2009,
2009
Abstract
Modern trade theory emphasizes firm-level productivity differentials to explain
the cross-border activities of non-financial firms. This study tests whether a
productivity pecking order also determines international banking activities. Using
a novel dataset that contains all German banks’ international activities, we
estimate the ordered probability of a presence abroad (extensive margin) and the
volume of international assets (intensive margin). Methodologically, we enrich the
conventional Heckman selection model to account for the self-selection of banks
into different modes of foreign activities using an ordered probit. Four main
findings emerge. First, similar to results for non-financial firms, a productivity
pecking order drives bank internationalization. Second, only a few non-financial
firms engage in international trade, but many banks hold international assets, and
only a few large banks engage in foreign direct investment. Third, in addition to
productivity, risk factors matter for international banking. Fourth, gravity-type
variables have an important impact on international banking activities.

Do Weak Supervisory Systems Encourage Bank Risk-taking?
Claudia M. Buch, G. DeLong
Journal of Financial Stability,
2008
Abstract
Weak bank supervision could give banks the ability to shift risk from themselves to supervisors. We use cross-border bank mergers as a natural experiment to test changes in risk and the impact of supervision. We examine cross-border bank mergers and find that the supervisory structures of the partners’ countries influence changes in post-merger total risk. An acquirer from a country with strong supervision lowers total risk after a cross-border merger. However, total risk increases when the target bank is located in a country with relatively strong supervision. This result is consistent with strong host regulators limiting the risky activities of their local banks. Foreign-owned competitors could then engage in the risky projects, especially if the foreign banks’ supervisors are not strong. An acquirer entering a country with strong supervision appears to shift risk back to its home country. The results suggest that bank supervisors can reduce total banking risk in their countries by being strong.
