We show that local banks provide corporate recovery lending to firms affected by ad-verse regional macro shocks. Banks that reside in counties unaffected by the natural disaster that we specify as macro shock increase lending to firms inside affected counties by 3%. Firms domiciled in flooded counties, in turn, increase corporate borrowing by 16% if they are connected to banks in unaffected counties. We find no indication that recovery lending entails excessive risk-taking or rent-seeking. However, within the group of shock-exposed banks, those without access to geographically more diversified interbank markets exhibit more credit risk and less equity capital.

The global financial crisis of 2007-08 and its adverse effects on economic activity have put financial stability back on the agenda of both researchers and policymakers. The regulatory debate has since then revolved around the question which reforms are needed to effectively reduce the likelihood and costs of future systemic financial crises. By now, the debate has led to an update of regulatory frameworks on the national, European, and global level. This thesis contributes to the empirical research on the risks to financial stability and to the debate on the regulation of international financial markets. It builds on some of the key insights from the recent global financial crisis and the respective policy responses. Chapter 1 of the thesis analyzes the reasons behind the strong co-movements of credit risk in sovereign bond markets during the financial crisis and the subsequent euro area debt crisis. In addition, it investigates to what extent high co-movements might be the outcome of contagion and through which channels contagion occurs. Chapter 2 investigates how uncertainty in banking affects banks’ loan supply, and it analyzes if the lending behavior is heterogeneous across different types of banks. Turning to the analysis of actual policies, Chapter 3 studies the effect of liquidity provided by the Eurosystem on macroeconomic adjustment in European crisis countries. Finally, Chapter 4 of the thesis assesses the effectiveness of a macroprudential policy instrument, caps on banks’ leverage, in stabilizing credit growth during financial downturns.

Mortgage companies (MCs) do not fall under the strict regulatory regime of depository institutions. We empirically show that this gap resulted in regulatory arbitrage and allowed bank holding companies (BHCs) to circumvent consumer compliance regulations, mitigate capital requirements, and reduce exposure to loan-related losses. Compared to bank subsidiaries, MC subsidiaries of BHCs originated riskier mortgages to borrowers with lower credit scores, lower incomes, higher loan-to-income ratios, and higher default rates. Our results imply that precrisis regulations had the capacity to mitigate the deterioration of lending standards if consistently applied and enforced for all types of intermediaries.

We document for a set of Latin American emerging countries that the different nature of foreign funding accessed by foreign and local banks affected their lending performance after September 2008. We show that lending growth was weaker for shock-affected foreign banks compared to shock-affected local banks. This evidence represents valuable policy information for regulators concerned with the stability and well-functioning of banking sectors.

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.

We analyze the inward and outward transmission of regulatory changes through German banks’ (international) loan portfolio. Overall, our results provide evidence for international spillovers of prudential instruments, these spillovers are however quite heterogeneous between types of banks and can only be observed for some instruments. For instance, foreign banks located in Germany reduce their loan growth to the German economy in response to a tightening of sector-specific capital buffers, local reserve requirements and loan to value ratios in their home country. Furthermore, from the point of view of foreign countries, tightening reserve requirements was effective in reducing lending inflows from German banks. Finally, we find that business and financial cycles matter for lending decisions.

In a proposed model of a multinational bank, interest margins determine local lending by foreign affiliates and the internal funding by parent banks. We exploit detailed parent-affiliate-level data of all German banks to empirically test our theoretical predictions in pre-crisis times. Local lending by affiliates depends negatively on price margins, the difference between lending and deposit rates in foreign markets. The effect of funding cost margins, the gap between local deposit rates faced by affiliates abroad and the funding costs of their parents, on internal capital market funding is positive but statistically weak. Interest margins are central to explain the interaction between internal capital markets and foreign affiliates lending.

Using exogenous liquidity windfalls from oil and natural gas shale discoveries, we demonstrate that bank branch networks help integrate U.S. lending markets. Banks exposed to shale booms enjoy liquidity inflows, which increase their capacity to originate and hold new loans. Exposed banks increase mortgage lending in nonboom counties, but only where they have branches and only for hard‐to‐securitize mortgages. Our findings suggest that contracting frictions limit the ability of arm's length finance to integrate credit markets fully. Branch networks continue to play an important role in financial integration, despite the development of securitization markets.

We analyze the impact of credit default swap (CDS) trading on bank syndication activity. Theoretically, the effect of CDS trading is ambiguous: on the one hand, CDS can improve risk-sharing and hence be a more flexible risk management tool than loan syndication; on the other hand, CDS trading can reduce bank monitoring incentives. We document that banks are less likely to syndicate loans and retain a larger loan fraction once CDS are actively traded on the borrower’s debt. We then discern the risk management and the moral hazard channel. We find no evidence that the reduced likelihood to syndicate loans is a result of increased moral hazard problems.

In this note we document political lending cycles for German savings banks. We find that savings banks on average increase supply of commercial loans by €7.6 million in the year of a local election in their respective county or municipality (Kommunalwahl). For all savings banks combined this amounts to €3.4 billion (0.4% of total credit supply in Germany in a complete electoral cycle) more credit in election years. Credit growth at savings banks increases by 0.7 percentage points, which corresponds to a 40% increase relative to non-election years. Consistent with this result, we also find that the performance of the savings banks follows the same electoral cycle. The loans that the savings banks generate during election years perform worse in the first three years of maturity and loan losses tend to be realized in the middle of the election cycle.
