The current financial crisis had its origins in the US subprime mortgage market and led to downturns in global equity, credit and commodity markets. This paper identifies the lack of economic information in risk valuation models as one reason why the financial industry was unable to predict,...

This paper provides an empirical study, which assesses the historical performance of credit rating agency (CRA) ratings for securitizations before and during the financial crisis. The paper finds that CRAs do not sufficiently address the systematic risk of the underlying collateral pools as well...

The mismatch between credit ratings o fstructured finance transactions and their true risks has been a source of the Global Financial Crisis which manifested in criticism of models and techniques applied by credit rating agencies (CRA). This paper provides an empirical study which assesses the...

Financial institutions are faced with the challenge to forecast future credit portfolio losses. It is common practice to focus on portfolio models consisting of a limited set of parameters, such as the probability of default, asset correlation, loss given default or exposure at default. A simple...

Recent studies find a positive correlation between default and loss given default rates of credit portfolios. In response, financial regulators require financial institutions to base their capital on 'Downturn' loss rates given default which are also known as Downturn LGDs. This article proposes...

This paper analyzes the level and cyclicality of bank capital requirement in relation to (i) the model methodologies through-the-cycle and point-in-time, (ii) four distinct downturn loss rate given default concepts, and (iii) US corporate and mortgage loans. The major finding is that less...

The following article develops a simultaneous multi-factor model for defaults and recoveries. Applying this model, risk parameters can be forecast using systematic and idiosyncratic risk fac-tors and their implied correlations. The theoretical framework is accompanied by an empirical analysis in...

This paper provides evidence for the relationship between credit quality, recovery rate, and correlation. The paper finds that rating grade, rating shift, and macroeconomic factors provide a highly significant explanation for default risk and recovery risk of US bond issues. The empirical data...
