The Impact of Public Guarantees on Bank Risk-taking: Evidence from a Natural Experiment

Abstract
In 2001, government guarantees for savings banks in Germany were removed following a lawsuit. We use this natural experiment to examine the effect of government guarantees on bank risk-taking. The results suggest that banks whose government guarantee was removed reduced credit risk by cutting off the riskiest borrowers from credit. Using a difference-in-differences approach we show that none of these effects are present in a control group of German banks to whom the guarantee was not applicable. Furthermore, savings banks adjusted their liabilities away from risk-sensitive debt instruments after the removal of the guarantee, while we do not observe this for the control group. We also document that yield spreads of savings banks’ bonds increased significantly right after the announcement of the decision to remove guarantees, while the yield spread of a sample of bonds issued by the control group remained unchanged. The evidence implies that public guarantees may be associated with substantial moral hazard effects.

Abstract
In October 2006, Dominion Bond Rating Service (DBRS) introduced new ratings for banks that account for the potential of government support. The rating changes are not a reflection of any changes in the respective banks’ credit fundamentals. We use this natural experiment to evaluate the consequences of bail out expectations for bank behavior using a difference in differences approach. The results suggest a striking difference between the effects of bail out probabilities during calm times (“ex ante”) versus during crisis times (“ex post”). During calm times, higher bail-out probabilities result in higher risk taking, consistent with the moral hazard view and much of the empirical literature. However, in crisis times, we find that banks with higher bail out probabilities tend to increase their risk taking less compared to banks that were ex ante unlikely to be bailed-out. Charter values are one part of the explanation: Supported banks may have a funding advantage relative to non-supported banks during the crisis. However, we cannot rule out that other factors also may be playing a role, including tighter supervision of supported banks in crisis times.

Competition, Risk-shifting, and Public Bail-out Policies

Review of Financial Studies,
Nr. 6,
2011
Abstract
This article empirically investigates the competitive effects of government bail-out policies. We construct a measure of bail-out perceptions by using rating information. From there, we construct the market shares of insured competitor banks for any given bank, and analyze the impact of this variable on banks' risk-taking behavior, using a large sample of banks from OECD countries. Our results suggest that government guarantees strongly increase the risk-taking of competitor banks. In contrast, there is no evidence that public guarantees increase the protected banks' risk-taking, except for banks that have outright public ownership. These results have important implications for the effects of the recent wave of bank bail-outs on banks' risk-taking behavior.

Die Entwicklung der Corporate Governance deutscher Banken seit 1950

Bankhistorisches Archiv,
Nr. 2,
2011
Abstract
The present paper gives an overview of the development of Corporate Governance of German banks since the 1950s. The focus will be on economic analysis. The most striking changes in Corporate Governance occurred with the ownership structure of commercial banks, in particular with the major joint-stock banks. In addition to that, the capital market has become a core element of Corporate Governance in all major German banks, which have replaced their prior concentration on the interests of a broadly defined circle of stakeholders by a one-sided concentration on shareholders’ interests. In contrast, with savings banks and cooperative cooperative banks, Corporate Governance has remained unchanged for the most part. Exceptions to this are the regional state banks: in their case, after they had turned away from traditional business models and in particular following the discontinuation of the guarantee obligation, the problems of their Corporate Governance, which were already discernible beforehand, became quite obvious. If you include the financial crisis, beginning in 2007, in the analysis, it becomes evident that it was precisely a Corporate Governance unilaterally geared to shareholders’ interest and the efficiency of the capital market that materially contributed to the evolution and widening of the crisis.

Korean Unification and Banking System - An Analysis in View of German Experiences and Korean Differences

IWH Discussion Papers,
Nr. 139,
2001
Abstract
One of the reforms that have to be launched in a future unification process in Korea, which seems possible after the political negotiations last year, is the transformation of the North Korean banking system. The question arises whether Korea could profit from the German experience where banking transformation was one of the rather few success stories in unification. In 1990 the East German banking transformation was achieved relatively fast and uncomplicated due to considerable direct investments of the West German banks compounded with state guarantees for bad loans resulting from the credit business with existing GDR-corporations. Unfortunately, South Korea currently lacks some major prerequesites that contributed to the German banking unification, among them – and probably the most important one – is the lack of a sound and efficient banking
system that could become active in the North. Consequently, depending on the circumstances of a future Korean unification either a more gradual process is recommended or, if inner-Korean migration requires a more dynamic transition, considerable investment by foreign banks and assistance from international organisations is recommended.
