Rating, Credit Spread, and Pricing Risky Debt: Empirical Study on Taiwan's Security Market
This paper focuses on evaluating the credit risk of corporate bond in the fixed income market of Taiwan. We apply Vasicek (1977) model into Merton's (1974) option framework and obtain a closed-form solution of the options model. The solution algorithm employs the Newton-Raphson method in combination with the inverse quadratic interpolation and bisection technique of Dekker (1967) to find out the roots and calculate the credit spread. The result shows that the average credit spread is 1.346%, and the credit spread of TSE (Taiwan Stock Exchange) listed firm is higher than that of OTC firms, while the one with bank guarantee is higher than the one without. We find negative correlation between VaR rating, TEJ (Taiwan Economic Journal) rating and credit spread, implying that the higher the market risk is, the lower the required premium is by the bondholders, and credit spread is expected to be lower. Testing the hypothesis of Duffee (1998), we find a negative correlation between the Taiwan Stock weighted index and credit spread. It implies that the term structure of interest rate is an upward type. As firm's equity value rises, the index return follows suit. While the bond default probability decreases, and the credit spread is expected to decrease.
