This study develops a framework for stress testing the credit exposures of Hong Kong's retail banks to macroeconomic shocks. Macro stress testing is performed with the framework to assess the vulnerability of banks' overall loan portfolios and mortgage exposures. A variety of shocks, similar to...

Empirical findings and theoretical studies suggest that firms adjust towards time-varying target leverage ratios. This paper studies the performances of the default probabilities generated from two stationaryleverage models with time-dependent and constant target ratios respectively. The...

This paper presents a benchmarking model for validation of default probabilities of listed companies for Basel II purposes. The model is based on the recent studies on the predictive capability of structural credit risk models. Benchmark ratings and one-year default probabilities are assigned to...

This paper studies the discriminatory power and calibration quality of the structural credit risk models under the 'exogenous default boundary' approach including those proposed by Longstaff and Schwartz (1995) and Collin-Dufresne and Goldstein (2001), and 'endogenous default boundary' approach...

This paper presents a theoretical model in which the supply of international dollar credit by a global bank is responsive to unconventional monetary policies (UMPs) both in the US and its home country, the functioning of the FX swap market and the bank's default risk. The theoretical model is...

Empirical findings and theoretical studies suggest that firms adjust toward time-varying target leverage ratios. This paper studies the performances of the default probabilities generated from two structural credit risk models (one with time-dependent leverage ratios and one with constant target...
