Crises, rescues, and policy transmission through international banks

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have withdrawn from foreign markets outside the US, but they have expanded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.

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.

Cross-border Exposures and Financial Contagion

International Review of Finance,
No. 2,
2010
Abstract
Integrated financial markets provide opportunities for expansion and improved risk sharing, but also pose threats of contagion risk through cross-border exposures. This paper examines cross-border contagion risk over the period 1999–2006. To that purpose we use aggregate cross-border exposures of 17 countries as reported in the Bank for International Settlements Consolidated Banking Statistics. We find that a shock that affects the liabilities of one country may undermine the stability of the entire financial system. Particularly, a shock wiping out 25% (35%) of US (UK) cross-border liabilities against non-US (non-UK) banks could lead to bank contagion eroding at least 94% (45%) of the recipient countries' banking assets. We also find that since 2006 a shock to Eastern Europe, Turkey and Russia affects most countries. Our simulations also reveal that the ‘speed of propagation of contagion’ has increased in recent years resulting in a higher number of directly exposed banking systems. Finally, we find that contagion is more widespread in geographical proximities.

A New Metric for Banking Integration in Europe
Reint E. Gropp, A. K. Kashyap
Europe and the Euro,
2010
Abstract
Most observers have concluded that while money markets and government bond markets are rapidly integrating following the introduction of the common currency in the euro area, there is little evidence that a similar integration process is taking place for retail banking. Data on cross-border retail bank flows, cross-border bank mergers and the law of one price reveal no evidence of integration in retail banking. This paper shows that the previous tests of bank integration are weak in that they are not based on an equilibrium concept and are neither necessary nor sufficient statistics for bank integration. The paper proposes a new test of integration based on convergence in banks' profitability. The new test emphasises the role of an active market for corporate control and of competition in banking integration. European listed banks profitability appears to converge to a common level. There is weak evidence that competition eliminates high profits for these banks, and underperforming banks tend to show improved profitability. Unlisted European banks differ markedly. Their profits show no tendency to revert to a common target rate of profitability. Overall, the banking market in Europe appears far from being integrated. In contrast, in the U.S. both listed and unlisted commercial banks profits converge to the same target, and high profit banks see their profits driven down quickly.

Cross-border Diversification in Bank Asset Portfolios
Claudia M. Buch, J.C. Driscoll, C. Ostergaard
International Finance,
forthcoming
Abstract
We compute optimally diversified international asset portfolios for banks located in France, Germany, Italy, the United Kingdom and the United States using the mean–variance portfolio model with currency hedging. We compare these benchmark portfolios with the actual cross-border asset positions of banks from 1995 to 2003 and ask whether the differences are best explained by regulations, institutions, cultural conditions or other financial frictions. Our results suggest that both culture and regulations affect the probability of a country's being overweighted in banks' portfolios: countries whose residents score higher on a survey measure of trust are more likely to be overweighted, while countries that have tighter capital controls are less likely to be overweighted. From a policy standpoint, the importance of culture suggests a limit to the degree of financial integration that may be achievable by the removal of formal economic barriers.

International Banking and Liquidity Allocation: Cross-border Financial Services versus Multinational Banking
Diemo Dietrich, Uwe Vollmer
Journal of Financial Services Research,
2010
Abstract
Diese Studie untersucht den komparativen Vorteil multinationaler Banken gegenüber dem grenzüberschreitenden Handel mit Finanzdienstleistungen hinsichtlich der Fähigkeit, vom globalen Zugang zu Finanzierungsquellen zu profitieren. Es wird argumentiert, dass der komparative Vorteil durch Nutzen und Kosten einer besonderen Kenntnis lokaler Märkte bestimmt wird. Für multinationale Banken liegt der Nutzen darin, eine höhere Produktivität zu erreichen und mehr Liquidität bereit zu stellen. Die Kosten bestehen darin, dass bestehdne Interessenskonflikte nur aufgrund der Spezifität des Wissens auch zu Ineffizienzen auf den bankinternen Kapitalmärkten führen; diese sind aber erforderlich, um Liquidität grenzüberschreitend zu alloziieren. Es werden die Bedingungen analysiert, unter denen multinationale Banken einen komparativen Vorteil haben, und es wird gezeigt, dass Mindesteigenkapitalvorschriften einen Einfluss hierauf ausüben, da sie das Ausmaß der Ineffizienzen interner Kapitalmärkte für verschiedene Organisationsformen unterschiedlich beeinflussen.

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.

Cross-Border Bank Contagion in Europe
Reint E. Gropp, M. Lo Duca, Jukka M. Vesala
International Journal of Central Banking,
No. 1,
2009
Abstract
We analyze cross-border contagion among European banks in the period from January 1994 to January 2003. We use a multinomial logit model to estimate, in a given country, the number of banks that experience a large shock on the same day (“coexceedances”) as a function of common shocks and lagged coexceedances in other countries. Large shocks are measured by the bottom 95th percentile of the distribution of the daily percentage change in distance to default of banks.We find evidence of significant cross-border contagion among large European banks, which is consistent with a tiered cross-border interbank structure. The results also suggest that contagion increased after the introduction of the euro.

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.
