Die Allokation des ökonomischen Kapitals stellt sowohl in der Theorie als auch in der Praxis ein zentrales Problem der Banksteuerung dar. Insbesondere Handelsentscheidungen und die Organisation von Handelsabteilungen in Kreditinstituten sind ein weit gehend unerforschtes Feld, das aber in der...

Risk parity is an asset allocation strategy designed so each asset class contributes equally to overall portfolio risk (as measured by volatility). While risk parity offers potential advantages, its success hinges on key assumptions and a favorable environment for bonds. Like the traditional...

We study capital requirements for bounded financial positions defined as the minimum amount of capital to invest in a chosen eligible asset targeting a pre-specified acceptability test. We allow for general acceptance sets and general eligible assets, including defaultable bonds. Since the...

This study shows that the statistical property of the commercial banks' rate of returns can be used to explain the resistance to using Value-at-risk (VaR) and stress tests to determine banks' capital adequacy. We showed that “fat-tail” risk requires more capital than the “normal tail”...

In modern frameworks for financial regulation such as Basel III, IV as well as Solvency II, financial institutions are regulated to maintain a certain level of capital to prepare for potential future losses. In this paper, we take the perspective of a regulator who designs regulatory capital...

This paper investigates systemic risk in the insurance industry. We first analyze the systemic contribution of the insurance industry vis-à-vis other industries by applying 3 measures, namely the linear Granger causality test, conditional value at risk and marginal expected shortfall, on 3...

We study the dependence between the downside risk of European banks and insurers. Since the downside risk of banks and insurers differs, an interesting question from a supervisory point of view is the risk reduction that derives from diversification within large banks and financial...

The simultaneous activation of many sources of risk can slow bank operations and even lead to bankruptcy. Credit risk is the greatest threat to the orderly functioning of a bank. To protect against its materialization banks spend nearly 90% of their total capital requirement. Concentration of...

Rather than taking on more risk, US insurers hit hard by the crisis pulled back from risk taking, relative to insurers hit less hard by the crisis. Capital requirements alone do not explain this risk reduction: insurers hit hard reduced risk within assets with identical regulatory treatment....
