Abstract: This paper develops a corporate bond pricing model following the structural approach in which the dynamics of the instantaneous risk-free interest rate is governed by the double square-root (DSR) process. Credit spreads generated from the pricing model depend explicitly upon the levels of interest rates via the non-linear effect arising from the DSR process. Given a positive correlation between the interest rates and leverage ratios, the credit spreads generated by the pricing model have negative relationship with the interest rates, that is consistent with empirical findings using bond market data during 2008–2013 when interest rates were low.
