國際板債券之再投資風險估計

Estimation of Reinvestment Risk of International Bonds

摘要


本研究將可贖回零息債券所有贖回情境下的最大預期損失與其再投資風險做連結,以歷史資料校正建立基於指數Lévy過程的國際板債券隱含年利率隨機模型,利用Fang and Oosterlee(2008, 2009)提出的COS法計算不同起始隱含年利率值下國際板債券於屆滿評估期限時的再投資風險與可贖回時點臨界利率。實證計算結果顯示,國際板債券之十年期再投資風險落在113至189基點間。

並列摘要


The reinvestment risk of the international bonds is associated with the maximum expected loss in all redemption scenarios, and the underlying stochastic internal rate of return model of international bonds follows the exponential Lévy process. The evaluation of the reinvestment risk is equivalent to the pricing of a certain non-standard Bermudan option and efficient numerical method such as the COS method proposed in Fang and Oosterlee (2008, 2009) can be applied. Under current market condition the reinvestment risk is estimated to be 113 - 189 bps, depending on the initial internal rate of return.
