Book excerpt: The current financial crisis has lessons for three areas of credit portfolio management. First, the credit crisis has highlighted the need to manage the funding risk of a bank. Second, it has highlighted the need to manage the underwriting risk of debt syndications. Finally, it has suggested the need to understand the drivers of relationship banking. The first paper in this dissertation develops an empirically grounded model to manage the funding risk of a bank. The second paper develops an option pricing framework to manage the underwriting risk in debt syndications. The last paper in this dissertation uses a proprietary dataset to study the empirical determinants of relationship banking benefits.

Book excerpt: Banks often seek to reduce the default risk exposure associated with their corporate loan portfolios by entering into credit derivative positions. Asset managers seek additional yield through single and multi-name credit derivatives, and must also manage their credit exposures according to disciplined and systematic risk-return analysis. This thesis explores the portfolio selection and risk measurement problem for credit sensitive financial instruments. In comparison to its equity counterpart, the fixed-income portfolio problem presents unique challenges: the risk of issuer default induces skewed return distributions, the correlation of defaults influences the tail of the portfolio return distribution, and credit derivative positions have complex risk-return implications. The first part of this dissertation addresses the static selection problem for a fixed-income portfolio of credit sensitive securities. We optimize the total mark-to-market value of the portfolio at the investment horizon. This value incorporates the intermediate premium and default cash flows of long and short cash and derivative positions, and the survival-contingent market value of these positions at the horizon. The selection problem is cast as a polynomial goal program that involves a two-stage constrained optimization of preference weighted moments of the portfolio mark-to-market. The decision variable is the vector of contract notionals. A capital constraint guarantees the solvency of the investor. The multi-moment formulation addresses the non-Gaussian distribution of the portfolio mark-to-market. It is also computationally tractable, because we obtain analytical expressions for the moments of the portfolio mark-to-market, which are given in terms of nested expectations under risk-neutral and actual probability measures. The expressions are valid for a broad class of intensity-based, doubly-stochastic models of correlated default timing that are widely used in portfolio credit risk and derivatives pricing. Numerical results illustrate the implications for portfolio selection of idiosyncratic default risk and default correlation. They also indicate the robustness of the optimal policies with respect to estimation errors. Although higher moments provide important characterizations of the portfolio risk profile, investment managers often need to compute specific tail percentiles of the profit and loss distribution. In the second part of the thesis we develop an analytical approximation for this distribution. The approximation is based on a small-time expansion of a transform of the portfolio value. The analytical characterization permits tractable computations of Value-at-Risk, and Value-at-risk constrained optimal portfolio selections.

Download or read book Active Credit Portfolio Management written by Jochen Felsenheimer and published by John Wiley & Sons. This book was released on 2006-03-10 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction of the euro in 1999 marked the starting point of the development of a very liquid and heterogeneous EUR credit market, which exceeds EUR 350bn with respect to outstanding corporate bonds. As a result, credit risk trading and credit portfolio management gained significantly in importance. The book shows how to optimize, manage, and hedge liquid credit portfolios, i.e. applying innovative derivative instruments. Against the background of the highly complex structure of credit derivatives, the book points out how to implement portfolio optimization concepts using credit-relevant parameters, and basic Markowitz or more sophisticated modified approaches (e.g., Conditional Value at Risk, Omega optimization) to fulfill the special needs of an active credit portfolio management on a single-name and on a portfolio basis (taking default correlation within a credit risk model framework into account). This includes appropriate strategies to analyze the impact from credit-relevant newsflow (macro- and micro-fundamental news, rating actions, etc.). As credits resemble equity-linked instruments, we also highlight how to implement debt-equity strategies, which are based on a modified Merton approach. The book is obligatory for credit portfolio managers of funds and insurance companies, as well as bank-book managers, credit traders in investment banks, cross-asset players in hedge funds, and risk controllers.

Available in PDF, EPUB and Kindle. Book excerpt: An innovative approach to post-crash credit portfolio management Credit portfolio managers traditionally rely on fundamental research for decisions on issuer selection and sector rotation. Quantitative researchers tend to use more mathematical techniques for pricing models and to quantify credit risk and relative value. The information found here bridges these two approaches. In an intuitive and readable style, this book illustrates how quantitative techniques can help address specific questions facing today's credit managers and risk analysts. A targeted volume in the area of credit, this reliable resource contains some of the most recent and original research in this field, which addresses among other things important questions raised by the credit crisis of 2008-2009. Divided into two comprehensive parts, Quantitative Credit Portfolio Management offers essential insights into understanding the risks of corporate bonds—spread, liquidity, and Treasury yield curve risk—as well as managing corporate bond portfolios. Presents comprehensive coverage of everything from duration time spread and liquidity cost scores to capturing the credit spread premium Written by the number one ranked quantitative research group for four consecutive years by Institutional Investor Provides practical answers to difficult question, including: What diversification guidelines should you adopt to protect portfolios from issuer-specific risk? Are you well-advised to sell securities downgraded below investment grade? Credit portfolio management continues to evolve, but with this book as your guide, you can gain a solid understanding of how to manage complex portfolios under dynamic events.

This book was released on 2011 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis discusses three topics in the area of quantitative finance in relation to risk and credit portfolio management. Chapter 2 investigates the issue of estimating and testing the goodness-of-fit of a model for a dependence break. The dependence is modelled by copulas and an unknown break of dependence structure is allowed for by including a dummy variable in the copula. The model is selected by minimizing the Akaike Information Criterion (AIC) of each candidate breaking point. The candidate models are estimated by a well-established two-step Maximum Likelihood (ML) approach, namely "Inference Function for Margin" (IFM). Moreover, we examine 5 single-factor copulas and compare them to each other by AIC criteria. A parametric bootstrap goodness-of-fit test is also proposed. Empirically, the dependence structures of stock indices between the US-UK and US-Japan markets during the Subprime crisis are examined. We found breaks in both dependence structures. In Chapter 3, a new general approach is developed for optimizing a credit portfolio by minimizing the default risk of a whole credit portfolio subject to a certain target premium. The approach is rooted in concepts from Modem Portfolio Theory. The default risk is measured by a quadratic form of weights and a matrix containing information about default correlations between any two single-names and default intensities of each single-name. The default correlation and the default intensities are modelled by a new binomial intensity model. A Genetic Algorithm (GA) approach is also introduced to optimize a credit portfolio with the purpose of overcoming limitations of the analytical method and the traditional numerical method based on the first order condition. Empirically, the approach is applied to optimize Credit Default Swap (CDS) portfolios consisting of members of iTraxx and CDX indices. In Chapter 4, we focus on modelling counterparty risks of two important financial instruments: the Interest Rate Swap (IRS) and the CDS. Analytical solutions are derived for the theoretical fair prices of the IRS and the CDS under various assumptions of defaults of counterparties. Also a Monte Carlo approach is proposed as a numerical solution for the fair prices. Numerical experiments are designed to study the effects of various factors on the fair price. Empirically, we examine the counterparty risk of a CDS portfolio, composed of randomly selected single-names from iTraxx series 10.

Book excerpt: This dissertation considers the measurement and management of portfolio credit risk. Collateralized debt obligations, which are securities with payoffs that are tied to the cash flows in a portfolio of defaultable assets such as corporate bonds, play a significant role in the financial crisis that has spread throughout the world. Insufficient capital provisioning due to flawed and overly optimistic risk assessments is at the center of the problem. In the first part of the dissertation, we develop stochastic methods to measure the risk of positions in collateralized debt obligations and related instruments tied to an underlying portfolio of defaultable assets. We propose an adaptive point process model of portfolio default timing, a maximum likelihood method for estimating point process models that is based on an acceptance/rejection re-sampling scheme, and statistical tests for model validation. To illustrate these tools, they are used to estimate the distribution of the profit or loss generated by positions in multiple tranches of a collateralized debt obligation that references the CDX High Yield portfolio, and the risk capital required to support these positions. The second part of the dissertation develops maximum likelihood estimators of the term structure of systemic risk in the U.S. financial sector, defined as the conditional probability of failure of a large number of financial institutions. The estimators are based on a new dynamic hazard model of failure timing that captures the influence of time-varying macro-economic and sector-specific risk factors on the likelihood of failures, and the impact of risk spillovers due to contagion or incomplete information about relevant risk factors. The estimation results, which cover the period January 1987 to December 2008, provide strong evidence for the presence of failure clustering not caused by variations in the observable explanatory covariates, which include the trailing return on the S & P 500 index, the lagged slope of the U.S. yield curve, the default and TED spreads, and other sector-specific variables.
