We provide insights into determinants of the rating level of 371 issuers which defaulted in the years 1999 to 2003, and into the leader-follower relationship between Moody's and S&P. The evidence for the rating level suggests that Moody's assigns lower ratings than S&P for all observed periods...

In den letzten Jahren wurden verschiedene Modelle entwickelt, um das Ausfallrisiko von Banken unter Berücksichtigung von Portfolioeffekten zu quantifizieren. Bisher hat sich kein Ansatz als allgemein akzeptierter Standard durchsetzen können. Da die Modelle grundlegende konzeptionelle...

Under a new Basel capital accord, bank regulators might use quantitative measures when evaluating the eligibility of internal credit rating systems for the internal ratings based approach. Based on data from Deutsche Bundesbank and using a simulation approach, we find that it is possible to...

Vergleichende Analyse alternativer Kreditrisikomodelle In den letzten Jahren wurden verschiedene Modelle entwickelt, um das Ausfallrisiko von Banken unter Berücksichtigung von Portfolioeffekten zu quantifizieren. Bisher hat sich kein Ansatz als allgemein akzeptierter Standard durchsetzen...

This study looks at potential windfall profits for the four banking acquisitions in 2023. Based on accounting figures, an FT article states that a total of USD 44bn was left on the table. We see accounting figures as a misleading analysis. By estimating marked-based cumulative abnormal returns...

We provide an assessment of the Basel Committee on Banking Supervision (BCBS) proposal to restrict the internal ratings-based approach on bank risk and to introduce risk-weighted asset floors. If well enforced, risk-sensitive capital regulation results in a more efficient credit allocation...

In this note, we first highlight different developments for banks under direct ECB supervision within the SSM that may prompt further investigation by supervisors. We find that banks that were weakly capitalized at the start of direct ECB supervision (1) still face elevated levels of...

Nach der 2008 startenden Finanzmarktkrise sind Maßnahmen zur Regulierung und Stabilisierung der Finanzmärkte in das Zentrum der politischen und der gesellschaftlichen Aufmerksamkeit gerückt. Insbesondere die hohen fiskalischen Kosten der Staaten zur Stützung ihrer Bankensysteme sowie die...

In this paper we argue that the own findings of the SSM THEMATIC REVIEW ON PROFITABILITY AND BUSINESS MODEL and the academic literature on bank profitability do not provide support for the business model approach of supervisory guidance. We discuss in the paper several reasons why the regulator...

This briefing paper describes and evaluates the law and economics of institution(al) protection schemes. Throughout our analysis, we use Europe's largest such scheme, that of German savings banks, as paradigm. We find strengths and weaknesses: Strong network-internal monitoring and early warning...
