    Abstract: 本文探討符合勞退新制下的GMxB變額年金商品之選擇權價值及避險方法,其中勞退新制下平均收益率不低於兩年期定存利率之保證是透過Vasciek模型預測短率後,透過Affine Term Structure Models將短率推回兩年期零息債券價格,並以此計算兩年期定存利率。本研究假設變額年金商品之投資連結標的為台灣大盤指數,以幾何布朗運動進行預測,並考慮利率和投資標的間之相關性。
    This article discusses the option value and hedging methods of GMxB products under the Taiwan new pension system. The average rate of return under the new pension system is not less than the two-year deposit rate. To value such interest rate guarantee, this research uses Vasciek model to capture the dynamics of short rate and obtain the future two-year deposit rate. We assume the underlying of the GMxB product is invested in the Taiwan Capitalization Weighted Stock Index. We then adopt the GBM model to project the future returns. The correlation between the underlying asset and the interest rate is considered.
    The traditional hedging methods for GMxB products are usually to buy options from investment banks, or use reinsurance. However, these methods are very expensive. Instead, this article considers futures as the hedging instruments. This article can provide a new method for insurance companies to hedge the guarantee risk when selling GMxB products, and activate the futures market in Taiwan.
