Innovative Transition Matrix Techniques For Measuring Extreme Risk: An Australian And U.S. Comparison, David Allen, Akhmad Kramadibrata, Robert Powell, Abhay Singh
Research outputs 2011
Comparing Australia and the U.S. both prior to and during the Global Financial Crisis (GFC), using a dataset which includes more than six hundred companies, this paper modifies traditional transition matrix credit risk modelling to address two important issues. Firstly, extreme credit risk can have a devastating impact on financial institutions, economies and markets as highlighted by the GFC. It is therefore essential that extreme credit risk is accurately measured and understood. Transition matrix methodology, which measur es the probability of a borrower transitioning from one credit rating to another, is traditionally used to m easure Value at Risk (VaR), …

Credit Risk Measurement Methodologies, David Allen, Robert Powell
Research outputs 2011
The significant problems experienced by banks during the Global Financial Crisis have highlighted the critical importance of measuring and providing for credit risk. This paper will examine four popular methods used in the measurement of credit risk and provide an analysis of the relative shortcomings and advantages of each method. The study includes external ratings approaches, financial statement analysis models, the Merton / KMV structural model, and the transition based models of CreditMetrics and CreditPortfolioView. Each model assesses different cr iteria, and an understanding of the merits and disadvantages of the various models can assist banks and other credit modellers …
Measuring Real Capital Adequacy In Extreme Economic Conditions: An Examination Of Swiss Banking Sector, David E. Allen, Robert Powell
Measuring Real Capital Adequacy In Extreme Economic Conditions: An Examination Of Swiss Banking Sector, David E. Allen, Robert Powell
Research outputs 2011
The global financial crisis (GFC) has placed the creditworthiness of banks under intense scrutiny. In particular, capital adequacy has been called into question. Current capital requirements make no allowance for capital erosion caused by movements in the market value of assets. This paper examines default probabilities of Swiss banks under extreme conditions using structural modeling techniques. Conditional Value at Risk (CVaR) and Conditional Probability of Default (CPD) techniques are used to measure capital erosion. Significant increase in Probability of Default (PD) is found during the GFC period. The market asset value based approach indicates a much higher PD than external …

Are Credit Ratings A Good Measure Of Capital Adequacy?, David Allen, Akhmad Kramadibrata, Robert Powell, Abhay Singh

Focus on capital adequacy intensified since the onset of the Global Financ ial Crisis (GFC), with many US and other global banks experiencing capital shortages over this time. The Basel standardised approach uses credit ratings as a determinant for corporate capital adequacy requirements. A problem with credit ratings is that they were designed to be a measure of relative, as opposed to absolute credit risk, and do not ratchet up or down with changes in economic circumstances. This paper examines how credit risk as indicated by credit ratings (and thei r associated capital requirement) changed pre and post Global Financial …
