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.
