A basket default swap is a derivative security tied to an underlying credit portfolio subjecting to various credit risks. The main challenge in valuing a BDS is to model the joint default times of all underlying assets’ efficiently. This study proposes a new algorithm to address this problem and price the BDS based on the conditional Monte Carlo method and the t-copula model. Several numerical experiments are conducted to evaluate the efficiency and the stability of the proposed conditional Monte Carlo algorithm. Results show that, compared with the famous Joshi-Kainth algorithm and the modified Joshi-Kainth algorithm, the proposed algorithm in this paper is more stable, offers substantial variance reduction and outperforms the plain Monte Carlo algorithm as well.
