Stress testing household debt
The authors estimate a county-level model of household delinquency and use it to conduct “stress tests” of household debt.
A FAVAR modeling approach to credit risk stress testing and its application to the Hong Kong banking industry
In this paper, a credit risk stress testing model based on the factor-augmented vector autoregressive (FAVAR) approach is proposed to project credit risk loss under stressed scenarios.
Credit exposure under the new standardized approach for counterparty credit risk: fixing the treatment of equity options
The new standardized approach for measuring counterparty credit risk exposures (SA-CCR) will replace the existing regulatory standard methods for exposure quantification. This paper provides empirical evidence that the SA-CCR parameters are not aligned…
Corporate default risk modeling under distressed economic and financial conditions in a developing economy
The authors create stepwise logistic regression models to predict the probability of default for private nonfinancial firms under distressed financial and economic conditions in a developing economy. Their main aim is to identify and interpret the…
A joint model of failures and credit ratings
The authors propose a novel framework for credit risk modeling, where default or failure information and rating or expert information are jointly incorporated in the model.
The impact of corporate social and environmental performance on credit rating prediction: North America versus Europe
The authors quantify the extent to which the quality of credit rating predictions improves by integrating measures of corporate social performance (CSP) in an established credit risk model. Their analysis provides comprehensive evidence of the…
Elliptical and Archimedean copula models: an application to the price estimation of portfolio credit derivatives
This paper explores the impact of elliptical and Archimedean copula models on the valuation of basket default swaps.
IFRS 9 compliant economic adjustment of expected credit loss modeling
This paper presents an International Financial Reporting Standard 9 (IFRS 9) compliant solution related to expected credit loss modeling.
Covid-19 and the credit cycle
The Covid-19 health crisis has dramatically affected just about every aspect of the economy, including the transition from a record long benign credit cycle to a stressed one, with still uncertain dimensions. This paper seeks to assess the credit climate…
Carbon pricing paths to a greener future, and potential roadblocks to public companies’ creditworthiness
In this paper, the authors introduce a valuation-based approach to estimate how energy transition risk may impact the creditworthiness of public companies globally within the next thirty years.
Art-secured lending: a risk analysis framework
In this study, the authors identify the three types of risks involved in an art-secured lending operation and present a framework to assess their combined effects via a Monte Carlo simulation.
An alternative statistical framework for credit default prediction
This study compares the gradient-boosting model with four other well-known classifiers, namely, a classification and regression tree (CART), logistic regression (LR), multivariate adaptive regression splines (MARS) and a random forest (RF).
Current expected credit loss procyclicality: it depends on the model
This work looks at a wide range of models to test the degree to which CECL is procyclical for different types of model.
A sensitivity analysis of the alpha factor
In this paper, we investigate the alpha factor’s sensitivity to key model parameters under stylized portfolio assumptions in order to better understand its complex characteristics. Our analysis is based on the numerical simulation of alpha sensitivities…
Quantifying systemic risk using Bayesian networks
Creditworthiness of individual entities may offer an insight into systemic risk of financial markets
Interpretability of neural networks: a credit card default model example
Recently developed techniques aimed at answering interpretability issues in neural networks are tested and applied to a retail banking case
One bad apple: default risk at CCPs
One clearing member's disproportionately large position increases the credit risk for all CCP members
Costs of capital under credit risk
In cost-of-capital computations, credit risk is only taken into consideration at the level of the debt beta approach. We show that applications of the debt beta approach in company valuation suffer from unrealistic assumptions about the market index and…
Basel risk weight functions and forward-looking expected credit losses
The authors establish that the combination of lifetime ECL and the Basel Capital Adequacy Framework, which relies on a one-year horizon, results in capital overestimation. Alongside this finding, and in order to alleviate the problem, they propose two…
Credit valuation adjustment wrong-way risk in a Gaussian copula model
In this paper, we present an analytical expression for CVA with WWR under the assumption of the lognormally distributed trade value.
On probability of default and its relation to observed default frequency and a common factor
This paper considers a definition of through-the-cycle as independent from an economic state that can result in a time-varying TTC probability of default.
Asset correlation estimation for inhomogeneous exposure pools
This study investigates the systematic error that is made if the exposure pool underlying a default time series is assumed to be homogeneous when in reality it is not.
An advanced hybrid classification technique for credit risk evaluation
In this paper, the authors employ a hybrid approach to design a practical and effective CRE model based on a deep belief network (DBN) and the K-means method.
