This paper derives indicators of the severity and structure of banking system risk from asymptotic interdependencies between banks’ equity prices. We use new tools available from multivariate extreme value theory to estimate individual banks’ exposure to each other (“contagion risk”) and...

Despite abundant empirical evidence on the merits and limits of early-warning systems for banking crises the day-to-day use of such systems seems to be limited. Reluctance to use such systems may partly be explained by the difficulties to operationalise the proposed models, which are often...

This paper compares four forms of inter-regional financial risk sharing: (i) segmentation, (ii) integration trough the secured interbank market, (iii) integration trough the unsecured interbank market, (iv) integration of retail markets. The secured interbank market is an optimal risk-sharing...

Im Risikomanagement von Banken findet das Value at Risk-Konzept verstärkt Anwendung. Baut die Solvenzpolitik einer Bank auf dem Value at Risk-Konzept auf, müssen Aktiv- und Passivgeschäft der Bank simultan betrachtet werden. In einem Entscheidungsmodell für eine Bank werden die notwendige...

This paper contributes to the economics of financial institutions risk management by exploring how loan securitization a.ects their default risk, their systematic risk, and their stock prices. In a typical CDO transaction a bank retains through a first loss piece a very high proportion of the...

Some have argued that recent increases in credit risk transfer are desirable because they improve the diversification of risk. Others have suggested that they may be undesirable if they increase the risk of financial crises. Using a model with banking and insurance sectors, we show that credit...

Over the term of a securitization transaction, the concept of non-compliance allows a securitizing bank to classify a securitized loan as materially non-compliant with certain transaction requirements. Such a loan becomes unqualified for loss allocation. Therefore, non-compliant loans can...

We study the implications of the value at risk concept for the bank's optimum amount of equity capital under credit risk. The market value of loans is risky and lognormally distributed. We show that the required equity capital depends upon managerial and market factors. Furthermore, the bank's...

Operationelle Risiken stellen für Banken nach dem Kreditrisiko die zweitwichtigste Risikokategorie dar. Ein effektives Risikomanagement der operationellen Risiken dürfte in Zukunft ein entscheidender Wettbewerbsfaktor sein. Im Rahmen der Neuregelung der bankaufsichtsrechtlichen Vorgaben...
