The traditional loans pricing methods are usually based on risk measures of individual loan's characteristics without considering the correlation between the defaults of different loans and the contribution of individual loans to the entire loan portfolio. In this study, using account-level...

This paper introduces a multivariate pure-jump Lévy process which allows for skewness and excess kurtosis of single asset returns and for asymptotic tail dependence in the multivariate setting. It is termed Variance Compound Gamma (VCG). The novelty of my approach is that, by applying a...

In this thesis I develop a model for describing the dynamic behavior of Credit Migration Matrices under a Point-in-time Rating Philosophy. Characteristics of the yearly Migration Matrices following a Point-in-Time Philosophy are presented. Through the introduction of the concept of Rating...

Developing analytic techniques for potential future exposure (PFE) of a general type transaction and applying it to credit value adjustment (CVA) and wrong way risk (WWR). The solutions provide a transparent and computationally friendly analytic formulas and good quality analytic estimates of...

This article presents the use of Least Squares Monte Carlo (LSMC) and Copula methodology for derivative option pricing including Counterparty Credit Risk. Since the financial crisis of 2008, the financial industry and the regulatory authorities began adjust the price of derivatives due to...

This paper explores the implications of systemic risk in Credit Structured Finance (CSF). Risk measurement issues loomed large during the 2007-08 financial crisis, as the massive, unprecedented number of downgrades of AAA senior bond tranches inflicted severe losses on banks, calling into...

As observed in the financial crisis, CDS spreads tend to increase simutaneously as a reaction to common shocks. Focusing on the spillover effects triggered by extreme events, we propose a credit risk analysis tool by applying credit default swap spread returns to the concept of 4CoVaR suggested...
