The paper argues that it would be natural to replace the standard normal distribution function by the logistic function in the regulatory Basel II (Vasicek's) formula. Such a model would be in fact consistent with the standard logistic regression PD modeling approach. An empirical study based on...

Using supervisory data for US banks, we evaluate the alignment of Basel II/III AIRB (Advanced Internal Ratings Based) risk estimates with portfolio risk. We use loan performance as a direct measure of portfolio risk as well as less direct market-based measures. Our results document that loan...

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...

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...

Basel framework for bank's capital adequacy has been criticized for its over reliance on external credit rating agencies. Moreover, implementation of Minimum Capital Requirement (MCR) under Basel-III is often linked to a decrease in economic growth as it requires banks to maintain a higher...

The extant literature suggests that one of the main causes of the recent financial crisis has been the excessive use of short-term debt by banks [Gorton and Metrick (2012a, b)]. Using a large sample of banks we find that increases in repurchase agreements (repos) was recognized by external...

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 the 'Downturn' loss rate given default which is also known as Downturn LGD. This article...

The paper analyzes a two-factor credit risk model allowing to capture default and recovery rate variation, their mutual correlation, and dependence on various explanatory variables. At the same time, it allows computing analytically the unexpected credit loss. We propose and empirically...

Although banks are required to document their equity capital for loans, corporate bonds, and other receivables, they are currently exempted from the procedure when investing in government bonds: they enjoy an “equity capital privilege.” As part of the Basel III regulatory framework redraft,...
