Basel III Capital Requirements and Heterogeneous Banks
IWH Discussion Papers,
I develop a theoretical model to investigate the effect of simultaneous regulation with a leverage ratio and a risk-weighted ratio on banks‘ risk taking and banking market structure. I extend a portfolio choice model by adding heterogeneity in productivity among banks. Regulators face a trade-off between the efficient allocation of resources and financial stability. In an oligopolistic market, risk-weighted requirements incentivise banks with high productivity to lend to low-risk firms. When a leverage ratio is introduced, these banks lose market shares to less productive competitors and react with risk-shifting into high-risk loans. While average productivity in the low-risk market falls, market shares in the high-risk market are dispersed across new entrants with high as well as low productivity.
Transposition Frictions, Banking Union, and Integrated Financial Markets in Europe
G20 Insights Policy Brief, Policy Area "Financial Resilience",
In response to the financial crisis of 2007/2008, policymakers implemented comprehensive changes concerning the regulation and supervision of banks. Many of those changes, including Basel III or the directives pertaining to the Single Rulebook in the European Union (EU), are agreed upon at the supranational level, which constitutes a key step towards harmonized regulation and supervision in an integrated European financial market. However, the success of these reforms depends on the uniform and timely implementation at the national level. Avoiding strategic delays to implement EU regulation into national laws should thus constitute a main target of the G20.

Banken-Stresstest 2016: Deutsche und italienische Banken mit ähnlichen Ergebnissen
Europäische Bankenaufsicht (EBA) und Europäische Zentralbank (EZB) haben die Ergebnisse ihres Banken-Stresstests 2016 vorgelegt. Der Test zeigt, dass die meisten europäischen Banken unter den angenommenen Stressszenarien recht stabil bleiben würden. „Bedenklich stimmt allerdings, dass die italienischen Banken nicht schlechter abschneiden als die deutschen Großbanken“, kommentiert IWH-Präsident Reint E. Gropp. „Eine Aufstockung des Eigenkapitals der beiden deutschen Großbanken scheint angeraten zu sein. Außerdem hat der Stresstest leider zwei entscheidende Faktoren nicht berücksichtigt: Erstens wurde eine lang anhaltende Niedrigzinspolitik der EZB nicht simuliert. Und zweitens berücksichtigt der Test nicht die Möglichkeit, dass viele kleine Institute gleichzeitig in Schwierigkeiten geraten könnten, was wiederum im Kontext der schwindenden Zinsmargen immer wahrscheinlicher werden könnte“, sagt Gropp. Der Stresstest sollte auch nicht davon ablenken, dringend die Probleme der italienischen Banken zu lösen.
The Role of Investment Banking for the German Economy: Final Report for Deutsche Bank AG, Frankfurt/Main
ZEW-Dokumentationen, Nr. 12-01,
The aim of this study is to assess the contributions of investment banking to the economy with a particular focus on the German economy. To this end we analyse both the economic benefits and the costs stemming from investment banking.
The study focuses on investment banks as this part of banking is particularly relevant for financing companies as well as the development and use of specific products to support the needs of private and professional clients. The assessment of benefits and costs of investment banking has been conducted from a European perspective. Nevertheless there is a focus on the German economy to allow a more detailed analysis of certain aspects as for example the use of derivatives by German companies, the success of M&As in Germany or the effect of securitization on loan supply and GDP in Germany. For comparison purposes other European countries and also the U.S. have been taken into account.
The last financial crisis has shown the negative impacts of banks on the financial system and the whole economy. In a study on the contribution of investment banks to systemic risk we quantify the negative side of the investment banking business.
In the last part of the study we assess how the effects of regulatory changes on investment banking. All important changes in banking and capital market regulation are taken into account such as Basel III, additional capital requirements for systemically important financial institutions, regulation of OTC derivatives and specific taxes.
Bank Market Discipline
ECB Monthly Bulletin,
This article reviews the conceptual issues surrounding market discipline for banks and describes to what extent market discipline could complement supervisory activities. The potential of market discipline has been explicitly recognised in the New Basel Accord. In addition to capital requirements (Pillar I) and supervisory review (Pillar II), the Accord provides for a greater role of financial markets in complementing traditional supervisory activities by asking banks for increased transparency with regard to their operations (Pillar III). This article puts Pillar III in the broader context of direct and indirect market discipline. It is argued that both direct and indirect market discipline should be enhanced by the transparency requirements of the New Capital Accord, but that other conditions may also need to be met in order for market discipline to become more effective. Nevertheless, the article also shows that aggregated market prices can play a useful role in monitoring banking sector stability.
