Over the last four decades the literature on bond rating changes and its effects on security prices increased significantly with almost all studies not controlling for the respective reason for those. We therefore investigate the impact of rating events on the stock and the credit default swap (CDS) market incorporating rating reviews and rating changes together with the reason mentioned by the rating agency. Our results for the general effects are in line with prior findings but conditioning on the respective reason shows that the markets’ anticipation of rating actions is largely driven by events due to changes in firms’ operating performance. Furthermore, we provide empirical evidence for the hypothesis in prior literature that a surprise downgrade does not necessarily have to be bad news for stockholders when wealth is transferred from bondholders, but negative rating actions are always bad news for bondholders. The results additionally reveal increasing rating announcement effects by declining credit quality of firms for both rating reviews and changes. JEL Classification: D82, G14, G20.

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 Unterschiede aufweisen und unterschiedliche empirische Inputdaten verwenden, hat die Auswahl eines Kreditrisikomodells unter Umständen einen erheblichen Einfluß auf die Kreditportfoliosteuerung der Bank. In diesem Beitrag soll deshalb geklärt werden, ob die Modelle systematisch abweichende Value-at-Risk-Werte berechnen und worin die Ursachen für auftretende Abweichungen liegen. Zunächst wird gezeigt, daß die bestehenden Kreditrisikomodelle in zwei grundlegende Klassen eingeteilt werden können: Assetwert-basierte Modelle und auf Ausfallraten basierende Modelle. Am Beispiel eines Musterportfolios von Krediten an deutsche Baufirmen werden zwei Vertreter der Modellklassen (CreditMetrics und CreditRisk+) verglichen und der Effekt der unterschiedlichen empirischen Inputparameter auf die Risikoergebnisse abgeschätzt. Die Analyse zeigt erhebliche Unterschiede zwischen den Modellen. Eine Analyse der Abweichungsursachen ergibt allerdings, daß der Grund für die großen Value-at-Risk-Unterschiede in erster Linie in den unterschiedlichen empirischen Inputdaten liegt, welche zu unterschiedlichen impliziten Korrelationsannahmen führen. Es wird gezeigt, wie die Modellparameter gewählt werden müssen, um identische Korrelationen zu erzeugen. Bei konsistenten Korrelationsannahmen stimmen die Ergebnisse beider Modelle weitgehend überein. Keywords: Credit Risk Models, credit risk correlation
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 identify strongly inferior rating systems out-of time based on statistics that measure either the quality of ranking borrowers from good to bad, or the quality of individual default probability forecasts. Banks do not significantly improve system quality if they use credit scores instead of ratings, or logistic regression default probability estimates instead of historical data. Banks that are not able to discriminate between high- and low-risk borrowers increase their average capital requirements due to the concavity of the capital requirements function.
The paper describes the legal and economic environment of mergers and acquisitions in Germany and explores barriers to obtaining and executing corporate control. Various cases are used to demonstrate that resistance by different stakeholders including minority shareholders, organized labour and the government may present powerful obstacles to takeovers in Germany. In spite of the overall convergence of European takeover and securities trading laws, Germany still shows many peculiarities that make its market for corporate control distinct from other countries. Concentrated share ownership, cross shareholdings and pyramidal ownership structures are frequent barriers to acquiring majority stakes. Codetermination laws, the supervisory board structure and supermajority requirements for important corporate decisions limit the execution of control by majority shareholders. Bidders that disregard the German preference for consensual solutions and the specific balance of powers will risk their takeover attempt be frustrated by opposing influence groups.

The paper explores factors that influence the design of financing contracts between venture capital investors and European venture capital funds. 122 Private Placement Memoranda and 46 Partnership Agreements are investigated in respect to the use of covenant restrictions and compensation schemes. The analysis focuses on the impact of two key factors: the reputation of VC-funds and changes in the overall demand for venture capital services. We find that established funds are more severely restricted by contractual covenants. This contradicts the conventional wisdom which assumes that established market participants care more about their reputation, have less incentive to behave opportunistically and therefore need less covenant restrictions. We also find that managers of established funds are more often obliged to invest own capital alongside with investors money. We interpret this as evidence that established funds have actually less reason to care about their reputation as compared to young funds. One reason for this surprising result could be that managers of established VC funds are older and closer to retirement and therefore put less weight on the effects of their actions on future business opportunities. We also explore the effects of venture capital supply on contract design. Gompers and Lerner (1996) show that VC-funds in the US are able to reduce the number of restrictive covenants in years with high supply of venture capital and interpret this as a result of increased bargaining power by VC-funds. We do not find similar evidence for Europe. Instead, we find that VC-funds receive less base compensation and higher performance related compensation in years with strong capital inflows into the VC industry. This may be interpreted as a signal of overconfidence: Strong investor demand seems to coincide with overoptimistic expectations by fund managers which make them willing to accept higher powered incentive schemes.
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 before the default event. Furthermore, we observe two-way Granger causal-ity, which signifies information flow between the two rating agencies. Since lagged rating changes influence the magnitude of the agencies’ own rating changes it would appear that the two rating agencies apply a policy of taking a severe downgrade through several mild down-grades. Further, our analysis of rating changes shows that issuers with headquarters in the US are less sharply downgraded than non-US issuers. For rating changes by Moody’s we also find that larger issuers seem to be downgraded less severely than smaller issuers.
The syndicated loan market, as a hybrid between public and private debt markets, comprises financial institutions with access to valuable private information about borrowers as a result of close bank-borrower relationships. In this paper, we seek empirical evidence for the costs of these relationships in a sample of UK syndicated loan contracts for the time period 1996 through 2005. Using detailed financial data for both borrowers (private and public companies) and for financial institutions, we find that undercapitalized banks charge higher loan spreads for loans to opaque borrowers using various measures for borrower opaqueness and controlling for bank, borrower and loan characteristics. We further analyze this hold-up effect over the business cycle and find that it only prevails during recessions. In expansion phases, however, we do not find evidence for banks exploiting their information monopoly. This finding is consistent with theories on bank reputation in bank loan commitments. Ambiguity about borrower financial health, which induces the information monopoly in the first place, also gives banks the discretion to exploit or not exploit informational captured borrowers. Our findings are both statistically and economically significant and robust to alternative bank and macroeconomic risk proxies. We address potential concerns about unobserved borrower heterogeneity exploiting the panel data nature of our sample. Using firm-bank fixed effect regressions, we find supporting evidence for our theoretical framework.

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 seems to be an important contributor to IPS network success. Similarly, the geographical quasi-cartel encourages banks to build a strong client base, including SME, in all regions. Third, the growth of the IPS member institutions may have benefitted from the strictly unlimited protection offered, in terms of euro amounts per account holder. The counterweighing weaknesses encompass the conditionality of the protection pledge and the underinvestment risk it entails, sometimes referred to as blackmailing the government, as well as the limited diversification potential of the deposit insurance within the network, and the near-incompatibility of the IPS model with the provisions of the BRRD, particularly relating to bail-in and resolution. Consequently, we suggest, as policy guidance, to treat large IPS networks similar to large banking groups, and put them as such under the direct supervision of the ECB within the SSM. Moreover, we suggest strengthening the seriousness of a deposit insurance that offers unlimited protection. Finally, to improve financial stability, we suggest embedding the IPS model into a multi-tier deposit re-insurance scheme, with a national and a European layer.

Do we need a bad bank?
(2009)
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 volkswirtschaftlichen Kosten infolge des Einbruchs des Wirtschaftswachstums in den Jahren nach der Insolvenz der US Investmentbank Lehman Brothers hatten einen globalen Konsens über die Notwendigkeit neuer Regulierungsmaßnahmen zur Folge. Im Ergebnis wurden das internationale Regulierungswerk Basel III sowie weitere nationale Maßnahmen zur Stabilisierung des Finanzsektors neu konzipiert und in Europa im Wege einer in nationales Recht umzusetzenden Richtlinie (die Capital Require-ments Directive IV - CRD IV) sowie einer Verordnung (die Capital Requirements Regulation CRR, welche unmittelbar geltendes Recht darstellt) eingeführt.
Vor diesem Hintergrund analysiert das vorliegende interdisziplinäre Gutachten die Auswirkungen der Regulierungsmaßnahmen, die zwischen 2008 bis zu Beginn des Jahres 2018 umgesetzt wurden auf dem deutschen Finanzsektor.
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 should stay away from intervening in management practices. We conclude that by taking the role of a coach instead of a referee, the supervisor generates a hazard for financial stability.
European households face tremendous obstacles when intending to open a savings account outside their home country. The shortage of deposits has become a major reason for banks’ declining loan supply and ultimately is responsible for a substantial part of the investment weakness and GDP decline in affected European countries.
Policy makers have made important efforts to promote European deposit market integration and to stimulate cross border flows of savings within the European Union. But these efforts will only yield the intended benefits if a number of additional non-tariff trade barriers are removed. Currently, these barriers prevent households in surplus countries to transfer their savings to banks in deficit countries where their deposits are most urgently needed.
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 compared to the standard approach. Thus, the internal ratings-based approach should be maintained. Further, the use of internal ratings-based output floors potentially results in unintended negative side effects. Input floors are likely a valuable tool to achieve risk-weighted assets comparability. Finally, the proposed measures have a potential detrimental impact for European banks as compared to others.
New provisioning rules introduced by IFRS 9 are expected to reduce the procyclicality of provisioning. Heterogeneity among banks in the procyclicality of provisioning may not only reflect the formal accounting rules, but also variation in discretionary provisioning policies. This paper presents empirical evidence on the heterogeneity of provisioning procyclicality among significant banks that are directly supervised by the ECB. In particular, this paper finds that provisioning is relatively procyclical at banks that have i) high loans-to-assets ratios, ii) high shares of non-interest income in total operating income, iii) low capitalization rates, and iv) low total assets. Supervisory guidance provided to banks on how to implement IFRS 9 has mostly been of a qualitative nature, and may prove inadequate to prevent an undesirably wide future variation in provisioning among EU banks.

How demanding and consistent is the 2018 stress test design in comparison to previous exercises?
(2018)
Bank regulators have the discretion to discipline banks by executing enforcement actions to ensure that banks correct deficiencies regarding safe and sound banking principles. We highlight the trade-offs regarding the execution of enforcement actions for financial stability. Following this we provide an overview of the differences in the legal framework governing supervisors’ execution of enforcement actions in the Banking Union and the United States. After discussing work on the effect of enforcement action on bank behaviour and the real economy, we present data on the evolution of enforcement actions and monetary penalties by U.S. regulators. We conclude by noting the importance of supervisors to levy efficient monetary penalties and stressing that a division of competences among different regulators should not lead to a loss of efficiency regarding the execution of enforcement actions.
This paper discusses policy implications of a potential surge in NPLs due to COVID-19. The study provides an empirical assessment of potential scenarios and draws lessons from previous crises for effective NPL treatment. The paper highlights the importance of early and realistic assessment of loan losses to avoid adverse incentives for banks. Secondary loan markets would help in this process and further facilitate bank resolution as laid down in the BRRD, which should be uphold even in extreme scenarios.
Die vorliegende empirische Studie analysiert die Vertragsgestaltung zwischen Investoren und europäischen Venture Capital-Fonds. Im Zentrum steht die Analyse der Vergütung des Fondsmanagements sowie der zum Einsatz kommenden Vertragsklauseln. Deren Ausgestaltung ist entscheidend für die Überwindung der Prinzipal-Agenten-Beziehung innewohnenden Agency-Probleme. Hierzu werden 122 Fondsprospekte sowie 46 Gesellschafterverträge von europäischen Venture Capital-Fonds ausgewertet, die in den Jahren 1996 bis 2001, der ersten großen Boomphase des europäischen Venture Capital-Marktes, aufgelegt wurden. Während die jährliche Vergütung des Fondsmanagements auf den ersten Blick sehr standardisiert erscheint, ergeben sich bei einer Barwertbetrachtung aller zu leistenden Management Fees über die gesamte Fondslaufzeit deutliche Anzeichen für Preisdifferenzierung. In Bezug auf den Einsatz von Vertragsklauseln kann eine Zunahme im Zeitablauf und mithin eine zunehmende Komplexität des Vertragsdesigns festgestellt werden. Vor dem Hintergrund der Erfahrungen aus dem US-amerikanischen Venture Capital-Markt kann diese Entwicklung jedoch noch nicht als abgeschlossen gelten. Der europäische Markt bewegt sich in Bezug auf die Verwendung vertraglicher Restriktionen auf dem Niveau, das in den USA bereits Anfang der neunziger Jahre erreicht war.
WE STUDY WHETHER PRIVATE EQUITY (PE) FIRMS HAVE A POSITIVE IMPACT ON THE FINANCIAL PERFORMANCE OF THEIR GERMAN PORTFOLIO COMPANIES BEFORE AND AFTER THE IPO. OUR EMPIRICAL ANALYSIS IS BASED ON A UNIQUE AND LARGE DATASET OF ALL IPOS IN GERMANY BETWEEN 2000 AND 2007. WE FIND THAT PE FIRMS SELECT COMPANIES WITH BELOW AVERAGE PERFORMANCE AND THEN IMPROVE PERFORMANCE SUBSTANTIALLY UNTIL THE IPO DATE AND IN MANY CASES ALSO THEREAFTER. THIS IMPLIES THAT PE FIRMS FILL A VOID ALSO IN GERMAN FINANCIAL MARKETS AND THAT THEY WILL ALSO PLAY A FUTURE ROLE IN FINANCING GERMAN ENTERPRISES.
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 non-performing loans, (2) are less cost-efficient and (3) reduced their share of subordinated debt financing over the last years. We then stress the importance of continuous and ongoing cost-benefit analysis regarding banking supervision in Europe. We also encourage processes to question existing supervisory practices to ensure a lean and efficient banking supervision. Finally, we underline the need of continuous and intensified coordination among regulatory bodies in the Banking Union since the efficacy of European bank supervision rests on its interplay with many different institutions.

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 (CAR), we find positive abnormal returns in all four cases which when made quantifiable, are around half of the FT’s accounting figures. Furthermore, we argue that transparent auctions with enough bidders should be preferred to negotiated bank sales.
