Download or read book Credit Correlation written by Alexander Lipton and published by World Scientific. This book was released on 2008 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent growth of credit derivatives has been explosive. The global credit derivatives market grew in notional value from $1 trillion to $20 trillion from 2000 to 2006. However, understanding the true nature of these instruments still poses both theoretical and practical challenges. For a long time now, the framework of Gaussian copulas parameterized by correlation, and more recently base correlation, has provided an adequate, if unintuitive, description of the market. However, the increased liquidity in credit indices and index tranches, as well as the proliferation of exotic instruments such as forward starting tranches, options on tranches, leveraged super senior tranches, and the like, have made it imperative to come up with models that describe market reality better. This book, originally and concurrently published in the International Journal of Theoretical and Applied Finance, Vol. 10, No. 4, 2007, agrees that base correlation has outlived its usefulness; opinions of how to replace it, however, are divided. Both the top-down and bottom-up approaches for describing the dynamics of credit baskets are presented, and pro and contra arguments are put forward. Readers will decide which direction is the most promising one at the moment. However, it is hoped that, in the near future, models that transcend base correlation will be proposed and accepted by the market. Sample Chapter(s). Introduction (31 KB).

Download or read book Portfolio Credit Risk and Macroeconomic Shocks written by Miguel A. Segoviano Basurto and published by International Monetary Fund. This book was released on 2006-12 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Portfolio credit risk measurement is greatly affected by data constraints, especially when focusing on loans given to unlisted firms. Standard methodologies adopt convenient, but not necessarily properly specified parametric distributions or simply ignore the effects of macroeconomic shocks on credit risk. Aiming to improve the measurement of portfolio credit risk, we propose the joint implementation of two new methodologies, namely the conditional probability of default (CoPoD) methodology and the consistent information multivariate density optimizing (CIMDO) methodology. CoPoD incorporates the effects of macroeconomic shocks into credit risk, recovering robust estimators when only short time series of loans exist. CIMDO recovers portfolio multivariate distributions (on which portfolio credit risk measurement relies) with improved specifications, when only partial information about borrowers is available. Implementation is straightforward and can be very useful in stress testing exercises (STEs), as illustrated by the STE carried out within the Danish Financial Sector Assessment Program.

Download or read book The Analytics of Risk Model Validation written by George A. Christodoulakis and published by Elsevier. This book was released on 2007-11-14 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk model validation is an emerging and important area of research, and has arisen because of Basel I and II. These regulatory initiatives require trading institutions and lending institutions to compute their reserve capital in a highly analytic way, based on the use of internal risk models. It is part of the regulatory structure that these risk models be validated both internally and externally, and there is a great shortage of information as to best practise. Editors Christodoulakis and Satchell collect papers that are beginning to appear by regulators, consultants, and academics, to provide the first collection that focuses on the quantitative side of model validation. The book covers the three main areas of risk: Credit Risk and Market and Operational Risk. *Risk model validation is a requirement of Basel I and II *The first collection of papers in this new and developing area of research *International authors cover model validation in credit, market, and operational risk
Download or read book Portfolio Credit Risk Models written by Michal Rychnovsky and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long before the Global Financial Crisis in the late-2000s, many academics and professionals were discussing the adequacy of using so called Gaussian copula models to evaluate the risk of collateralized debt obligations (CDOs). Many of them pointed out that such models are too simplifying the complicated correlation structure of portfolios. Indeed, this was afterwards identified as one of the key factors spreading the crisis. In this book, we would like to introduce the basic mathematical theory of the copula-based portfolio credit risk models and some of their generalizations. We start by introducing the terms of probability of default and expected loss, as well as some common obligor models. Then we give an example of a duo basket model, followed by mathematical definitions of copulas and various dependence measures. Finally, we focus on threshold models and their limit behavior for the number of loans going to infinity. This book is written in a scientifically rigorous but still easy-to-read style providing many new insights into this topic.
Download or read book Managing Portfolio Credit Risk in Banks written by Arindam Bandyopadhyay and published by Cambridge University Press. This book was released on 2016-05-09 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Credit risk is the risk resulting from the uncertainty that a borrower or a group of borrowers may be unwilling or unable to meet their contractual obligations as per the agreed terms. It is the largest element of risk faced by most banks and financial institutions. Potential losses due to high credit risk can threaten a bank's solvency. After the global financial crisis of 2008, the importance of adopting prudent risk management practices has increased manifold. This book attempts to demystify various standard mathematical and statistical techniques that can be applied to measuring and managing portfolio credit risk in the emerging market in India. It also provides deep insights into various nuances of credit risk management practices derived from the best practices adopted globally, with case studies and data from Indian banks.

Download or read book A Credit Contagion Model for Loan Portfolios in a Network of Firms with Spatial Interaction written by Diana Barro and published by . This book was released on 2012 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This contribution studies the effects of credit contagion on the credit risk of a portfolio of bank loans. To this aim we introduce a model that takes into account the counterparty risk in a network of interdependent firms that describes the presence of business relations among different firms. The location of the firms is simulated with probabilities computed using an entropy spatial interaction model. By means of a wide simulation analysis we use the model proposed to study the effects of default contagion on the loss distribution of a portfolio.
