This paper develops an empirical procedure for analyzing the impact of model misspecification and calibration errors on measures of portfolio credit risk. When applied to large simulated portfolios with realistic characteristics, this procedure reveals that violations of key assumptions of the...

Jamshidian and Zhu (1997) propose a discrete grid method for simplifying the computation of Value at Risk (VaR) for fixed-income portfolios. Their method relies on two simplifications. First, the value of fixed income instruments is modeled as depending on a small number of risk factors chosen...

This paper examines the systematic relationship between correlation mis-estimation and the corresponding Value-at-Risk (VaR) mis-calculation. To this end, first a semi-parametric approach, and then a parametric approach is developed. Both approaches are based on a simulation setup. Various...

Contingent credit lines (CCLs) are widely used in bank lending and also play an important role in the functioning of short-term capital markets. Yet, their pricing and hedging has not received much attention in the finance literature. Using a financial engineering approach, the paper analyzes...

We look at the effect of capital rules on a banking system that is connected through correlated credit exposures and interbank lending. The rules, which combine individual bank characteristics and interconnectivity measures of interbank lending, are to minimize a measure of system-wide losses....

This paper looks at the effect of capital rules on a banking system that is connected through correlated credit exposures and interbank lending. Keeping total capital in the system constant, the reallocation rules, which combine individual bank characteristics and interconnectivity measures of...

In this paper it is shown how a Vasicek-model approach and the assumptions in Basel 2 regulatory framework can be used to develop measures of the probability of banks' failure. The Basel 2 framework is based on a Vasicek-model approach. The estimation of the propose measure of bank probability...

We treat the banking system as a traded credit portfolio and calculate systemic risk capital as the amount of capital that insures the portfolio's value against unexpected losses. Using data from the largest global financial institutions, we find evidence of extreme event dependence between...

This paper maps the empirical features of the Loan-to-Deposit (LTD) ratio with an eye on using it in macroprudential policy to mitigate liquidity risk. We inspect the LTD trends and cycles of 11 euro area countries by filtering methods and analyze the interaction between loans and deposits. We...

This paper evaluates the optimal bail-out and bail-in mix in the case of bankruptcy of Banco Espírito Santo (BES), SA, the second largest Portuguese private bank. The solution after the crisis of the BES, was to partition the bank into a good bank (Novo Banco (New Bank)) and keep the toxic...
