The regulator’s trade-off: Bank supervision vs. minimum capital

We develop a simple model of banking regulation with two policy instruments: minimum capital requirements and the supervision of domestic banks. The regulator faces a trade-off: high capital requirements cause a drop in the banks’ profitability, whereas strict supervision reduces the scope of intermediation and is costly for taxpayers. We show that a mix of both instruments minimises the costs of preventing the collapse of financial intermediation. Once we allow for cross-border banking, the optimal policy is not feasible. If domestic supervisory effort is not observable, our model predicts a race to the bottom in capital requirement regulation. Therefore, countries are better off by harmonising regulation on an international standard.     

Macro-Networks: An application to euro area financial accounts

This paper develops a financial network, designated the “Macro-Network”, that depicts the connections between the main financial and non-financial sectors of the economy in the various financial instruments of the euro area. The Macro-Network comprises of linkages across financial and non-financial sectors in each country. These country-level sector networks are then connected by the cross-border links between the individual banking sectors. Using the Macro-Network to simulate financial shocks, we find that the propagation effects depend on the underlying network structure, which evolves over time. After the financial crisis, bilateral linkages contracted sharply, reflecting the surge in counterparty risk and the de-leveraging processes. Nonetheless, our analysis suggests that even after this process, vulnerabilities remained in the euro area financial system, while a more diversified portfolio of cross-border exposures might mitigate the shock effects. We identify sectors which are most relevant for the propagation of financial shocks in the Macro-Network.     

Financial crises and the composition of cross-border lending

We examine the composition and drivers of cross-border bank lending between 1995 and 2012, distinguishing between syndicated and non-syndicated loans. We show that on-balance sheet syndicated loan exposures, which account for almost one third of total cross-border loan exposures, increased during the global financial crisis due to large drawdowns on credit lines extended before the crisis. Our empirical analysis of the drivers of cross-border loan exposures in a large bilateral dataset leads to three main results. First, banks with lower levels of capital favor syndicated over other kinds of cross-border loans. Second, borrower country characteristics such as level of development, economic size, and capital account openness, are less important in driving syndicated than non-syndicated loan activity, suggesting a diversification motive for syndication. Third, information asymmetries between lender and borrower countries became more binding for both types of cross-border lending activity during the recent crisis.     

The mix of international banks’ foreign claims: Determinants and implications

We analyze the cross-country determinants and financial stability implications of the mix of international banks’ foreign claims. We distinguish between local claims – extended by host country affiliates – and cross-border claims – booked outside the receiving country. Using data on Italian, Spanish, and US banks’ foreign claims, we find that the share of local claims is driven by restrictions on banking sector openness and by local scale economies/business opportunities. The impact of limits on property rights, entry requirements, start-up and informational costs is less robust. Finally, foreign claim volatility is lower in countries with a larger share of local claims.     

Cross-border banking,bank market structures and market power: Theory and cross-country evidence

Patterns in cross-border banking have changed since the global financial crisis. This may affect domestic bank market structures and macroeconomic stability in the longer term. In this study, I theoretically and empirically analyze how different modes of cross-border banking impact bank concentration and market power. I use a two-country general equilibrium model with heterogeneous banks developed by DeBlas and Russ (2010a) to grasp the effect of cross-border lending and foreign direct investment in the banking sector on bank market structures. The model suggests that both cross-border lending and bank FDI mitigate concentration. Empirical evidence from a panel dataset of 18 OECD countries supports the theoretical predictions: higher volumes of bank FDI and of cross-border lending coincide with lower Herfindahl-indexes in bank credit markets.     

Foreign banks in syndicated loan markets

Foreign banks play a prominent role in syndicated loan markets. In this paper we examine foreign banks’ motives in participating in cross-border deals in 25 European countries. We find that usual explanations of foreign banking activities can only account partly for the high rate of foreign involvement in syndicated loan markets. The usual argument is that foreign banks are at a disadvantage because they lack soft information and thus they tend to lend to more transparent firms compared to their domestic counterparts. We find that this relationship only holds in relatively small financial systems. We illustrate different motivations for the large amount of cross border lending in large developed markets. In these markets foreign banks tend to lend to especially risky borrowers and projects.     

Competition in fragmented markets: New evidence from the German banking industry in the light of the subprime crisis

Of all of the EU member states, Germany has the largest banking market. However, not all German banking institutions necessarily face fierce competition. Because the industry is highly fragmented, strict separation of the three existing banking pillars may impede competition, with negative effects on financial stability. We assess the competitive stances of 1,888 universal banks from 2001 to 2009 by using the Panzar–Rosse revenue test. We find evidence that measuring competition at an average country level does not necessarily generate valid evaluations of fragmented markets. In addition, we find no clear indication that either the particular objectives of cooperative and savings banks or the legal protection of these institutions impedes competition or discriminates against private banks. Therefore, as long as the relationship between competition and financial stability is dubious, the overall effect and the social costs or benefits of political measures that influence the structure of the German banking market are at least questionable.     

Cross-border interbank networks,banking risk and contagion

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.

Multinational banking and the international transmission of financial shocks: Evidence from foreign bank subsidiaries

Using bank-level data on 368 foreign subsidiaries of 68 multinational banks in 47 emerging economies during 1994–2008, we present consistent evidence that internal capital markets in multinational banking contribute to the transmission of financial shocks from parent banks to foreign subsidiaries. We find that internal capital markets transmit favorable and adverse shocks by affecting subsidiaries’ reliance on their own internal funds for lending. We also find that the transmission of financial shocks varies across types of shocks; is strongest among subsidiaries in Central and Eastern Europe, followed by Asia and Latin America; is global rather than regional; and becomes more conspicuous in recent years. We also explore various conditions under which the international transmission of financial shocks via internal capital markets in multinational banking is stronger, including the subsidiaries’ reliance on funds from their parent bank, the subsidiaries’ entry mode, and the capital account openness and banking market structure in host countries.     

Banking integration and growth: Role of banks' previous industry exposure

Using U.S. interstate banking deregulations, we identify the effect of market-entering banks’ prior industry exposures on the manufacturing sector growth in the new state that they enter. We create banking integration and industry specialization measures that consider both direct (state-pair) as well as indirect (tertiary-state) links created by expanding multi-bank holding company networks. First, consistent with the economic mechanism we have in mind, we observe that banks’ home state's industrial specialization is positively correlated with their lending specialization when participating to in-state as well as out-of-state syndicated loan markets. Then, focusing on industry value added at the state-industry-level, we find evidence consistent with the positive impact of market-entering banks’ prior exposure to a sector on the growth of that industry in the newly-entered state. The observed effect is larger when the state-pair-level discrepancy in sector-specialization is greater. Our findings are robust and hold in capital-related components of industry-level value added. We observe that the above results are more prominent in sectors that are more external finance dependent, have lower amounts of physical capital that can be pledged as collateral, generate more valuable patents, are durables-producers, and have a higher risk. Our findings suggest that a bank integration channel helps shape states’ industrial landscape.     

A compound option approach to model the interrelation between banking crises and country defaults: The case of Hungary 2008

We analyze the Hungarian financial crisis of 2008 in a stochastic framework that advances structural credit risk models for country defaults: by applying compound option theory we consider payments for bailing-out the banking sector together with debt service payments in a joint crisis model. We estimate the model parameters by applying the time series maximum-likelihood approach of Duan (1994) on yield spreads of Hungarian Bonds. We find that difficulties in acquiring funds for debt servicing in combination with high outstanding debt triggered the crisis, rather than problems in the domestic banking sector. The estimated crisis probabilities dramatically rise during 2008.     

Hierarchical determinants of capital structure

We analyze the influence of time-, firm-, industry- and country-level determinants of capital structure. First, we apply hierarchical linear modeling in order to assess the relative importance of those levels. We find that time and firm levels explain 78% of firm leverage. Second, we include random intercepts and random coefficients in order to analyze the direct and indirect influences of firm/industry/country characteristics on firm leverage. We document several important indirect influences of variables at industry and country-levels on firm determinants of leverage, as well as several structural differences in the financial behavior between firms of developed and emerging countries.     

Estimating systemic risk in the international financial system

This paper develops three distinct methods to quantify the risk of a systemic failure in the global banking system. We examine a sample of 334 banks (representing 80% of global bank equity) in 28 countries around five global financial crises. Our results suggest statistically significant, but economically small, increases in systemic risk. Although policy responses are endogenous, the low estimated probabilities suggest that the distress of central bankers, regulators and politicians about the events we study could be overstated and that current policy responses to financial crises could be adequate to handle major macroeconomic events.     

Testing the fire-sale FDI hypothesis for the European financial crisis

Using a panel of corporate transactions in 27 EU countries from 1999 to 2012, we investigate the impact of the financial crisis on the market for corporate assets. In particular, we test the ‘fire-sale FDI’ hypothesis by analyzing the number of cross-border transactions, the price of corporate assets and the impact of credit and macroeconomic conditions. According to the fire-sale FDI hypothesis, countries affected by a crisis attract foreign buyers selling assets at a discount. We find a dampening effect of the crisis on cross-border transactions in all EU countries. Although countries with higher sovereign default risk and lower economic demand attracted more foreign buyers in the crisis, lower domestic credit is associated with less cross-border transactions. Corporate assets in crisis countries are cheaper, particularly if domestic credit is low; however, these findings are not limited to the crisis period. This pattern is strikingly different from the East Asian and Latin American financial crises. Overall, we find little evidence for ‘fire-sale FDI’ suggesting an integrated European market without significant frictions.     

Transatlantic systemic risk

In this paper we study systemic risk for the US and Europe. We show that banks’ exposures to common risk factors are crucial for systemic risk. We come to this conclusion by first showing that relations between US and European banks are smaller than within each region. We then show that European banks react more strongly to the onset of the financial crisis than US banks. Regarding the consequences of systemic risk, we show that dependence between the banking sector and a wide range of real sectors is limited. Our results imply that regulators and supervisors should address international bank dependencies arising from common risk factors, while recessions in real sectors due to bank defaults should be a secondary concern.     

Can European bank bailouts work?

Cross-border banking needs cross-border recapitalisation mechanisms. Each mechanism, however, suffers from the financial trilemma, which is that cross-border banking, national financial autonomy and financial stability are incompatible. In this paper, we study the efficiency of different burden-sharing agreements for the recapitalisation of the 30 largest banks in Europe. We consider bank bailouts for these banks in a simulation framework with stochastic country-specific bailout benefits. Among the burden sharing rules, we find that the majority and qualified-majority voting rules come close to the efficiency of a bailout mechanism with a supranational authority. Even a unanimous voting rule works better than home-country bailouts, which are very inefficient. If we assume additional systemic risk benefits, the efficiency of burden sharing rules comes close to the supranational solution.     

Financial market integration and the value of global diversification: Evidence for US acquirers in cross-border mergers and acquisitions

In contrast to the previously documented cross-border discount, we find that there is positive cross-border effect for US acquirers during late 1990s and early 2000s. This is especially particular the case for those that acquire/merge with targets from segmented financial markets where acquirers experience significantly higher positive abnormal returns than those that acquire targets from integrated financial markets. Furthermore, firms acquiring segmented-market targets are also characterized by significantly higher post-merger operating performance improvement. The results indicate that the observed positive cross-border effect is mainly due to the increase in the number of transactions involving targets from segmented markets, in which the average firm experience significant financial constraints. We contend that value is created by a combination of firms with different financial market integration status, in which funds are provided to high cost firms. The finding that the value creation is even higher within the group of acquirers with a lower cost of capital provides additional support for our conjecture.     

FDI versus exports: Evidence from German banks

We use a new bank-level dataset to study the FDI-versus-exports decision for German banks. We extend the literature on multinational firms in two directions. First, we simultaneously study FDI and the export of cross-border financial services. Second, we test recent theories on multinational firms which show the importance of firm heterogeneity [Helpman, E., Melitz, M.J., Yeaple, S.R., 2004. Export versus FDI. American Economic Review 94 (1), 300–316]. Our results show that FDI and cross-border services are complements rather than substitutes. Heterogeneity of banks has a significant impact on the internationalization decision. More profitable and larger banks are more likely to expand internationally than smaller banks. They have more extensive foreign activities, and they are more likely to engage in FDI in addition to cross-border financial services.     

Mergers and Long-Term Corporate Performance: Evidence from Cross-Border Bank Acquisitions

We provide evidence on operating performance changes at a sample of U.S. banks acquired by non-U.S. banking organizations over the 1980–2001 period. Our sample allows us to compare directly the preacquisition performance of the targets with their postacquisition performance, a comparison that has not been possible in prior studies. We find that these cross-border acquisitions produce improved target performance. Cash flow profitability at the target increases, labor utilization improves, and loan losses do not rise. We also find evidence that the improvement in target operating performance primarily takes place for those acquisitions that occur following passage of the Reigle–Neal interstate branching legislation.
