Das deutsche Bankensystem ruht seit Jahrzehnten auf drei Säulen: den privaten Kreditbanken, den öffentlichen Banken des Sparkassensystems und den genossenschaftlichen Banken. Das Drei-Säulen-System scheint ursächlich für die Stabilität im deutschen Bankensystem zu sein. Gerade die Krise hat gezeigt, dass es für ein Bankensystem vorteilhaft ist, wenn es darin nicht nur einen Typus von Banken gibt. Wir müssen eine Pluralität von Organisationsformen im Bankwesen erhalten und weiterentwickeln.
The recent financial crisis has led to a major debate about fair-value accounting. Many critics have argued that fair-value accounting, often also called mark-to-market accounting, has significantly contributed to the financial crisis or, at least, exacerbated its severity. In this paper, we assess these arguments and examine the role of fair-value accounting in the financial crisis using descriptive data and empirical evidence. Based on our analysis, it is unlikely that fair-value accounting added to the severity of the current financial crisis in a major way. While there may have been downward spirals or asset-fire sales in certain markets, we find little evidence that these effects are the result of fair-value accounting. We also find little support for claims that fair-value accounting leads to excessive write-downs of banks’ assets. If anything, empirical evidence to date points in the opposite direction, that is, towards overvaluation of bank assets.
This paper deals with the proposed use of sovereign credit ratings in the "Basel Accord on Capital Adequacy" (Basel II) and considers its potential effect on emerging markets financing. It investigates in a first attempt the consequences of the planned revisions on the two central aspects of international bank credit flows: the impact on capital costs and the volatility of credit supply across the risk spectrum of borrowers. The empirical findings cast doubt on the usefulness of credit ratings in determining commercial banks' capital adequacy ratios since the standardized approach to credit risk would lead to more divergence rather than convergence between investment-grade and speculative-grade borrowers. This conclusion is based on the lateness and cyclical determination of credit rating agencies' sovereign risk assessments and the continuing incentives for short-term rather than long-term interbank lending ingrained in the proposed Basel II framework.
