Abstract: | 隨著利率頻頻走低,壽險業過去發行的保單皆面臨利差損問題,因應未來可能的龐大給付責任,勢必須關注準備金對利率變化的敏感度。本研究以不同保單年度與不同預定利率條件下,以遞延年金與終身壽險商品為例,分析利率波動對保險公司負債面影響,推估準備金分佈及衡量準備金價值變動之風險。 本文以Orthogonal-GARCH模型估計利率動態,取代表性因子配適時間序列模型,再利用蒙地卡羅模擬利率隨機情境,長期利率採Smith-Wilson法配適,得到完整的利率期限結構。以VaR(Value at Risk)量化未來責任之風險,結果顯示預定利率高的情況下,需承擔較多的風險,而隨時間經過,準備金風險對整體負債影響性會降低。此外,在保單年度中期時,利率波動對準備金影響效果較明顯,視為保險商品生命週期的關鍵時期,此時對於利率風險的管理更為重要。 With interest rates falling frequently, the life insurance company previously issued the policy is facing the problem of interest loss. In response to the possibility of future large payment of responsibility, it is important to pay attention to the sensitivity of the reserve to interest rate changes. With deferred annuity and whole life insurance products as an example, we analyze the impact of interest rate fluctuations on the liability of insurance companies, estimates the distribution of reserves and the risk of changes in reserve value based on different policy year and different actuarial assumption interest rate. In this paper, the Orthogonal-GARCH model is used to estimate the interest rate dynamics by selecting the representative factor to fit the time series model. The Monte Carlo method is used to simulate the interest rate stochastic situation, and the long-term interest rate is adopted by Smith-Wilson method to obtain the complete interest rate term structure. To quantify the risk of future liability by VaR, the results show that the high actuarial assumption interest rate policy to bear more risk, and over time the impact of reserve risk on overall liability will be reduced. In addition, in the middle of the policy year, the impact of interest rate fluctuations on the reserve effect is obvious, as a critical period of insurance product life cycle, so this period is more important for the management of interest rate risk. |
