近年來台灣的市場利率持續下滑，可能造成保險公司無法實現對被保險人之高預定利率的保單給付承諾，利率風險已經成為壽險公司是否能繼續經營之重要關鍵。壽險公司如未能衡量利率變動風險而貿然推出保單，將對財務造成極大的負擔，不但會影響公司清償能力，亦會對社會造成衝擊，因此壽險公司應先衡量現在及未來將面臨多大的利率風險，做適當資產負債管理，以避免將來失卻清償能力。
本研究利用財務上平均存續期間（duration）觀念與Barney（1997）所提出之K值來衡量利率風險，以民國87-89年財務報表資料，實證研究利率風險會對那些經營指標產生影響，以喚起業界對於利率風險之重視。研究結果發現：
1.利率風險對於壽險公司之投資報酬率、股東權益報酬率有顯著的影響，並且呈負相關。
2.利率風險對於壽險公司之流動比率無顯著相關；與負債比率有顯著之正相關。
3.利率風險對於新契約保費成長率、保單繼續率無顯著影響，顯示國內並無明顯之逆中介情況。
4.壽險公司可藉由投資較長期之公債、公司債及減少保單貸款、不動產投資與固定資產項目之利率敏感度，以增加壽險公司之獲利性。 / The interest rates have been decreasing recently. Under this circumstance, it might be difficult for insurance companies to gain sufficient investment returns to fulfill the commitment of insurance policies. The interest-rate risk has become one of the critical factors for the solvency of life insurance companies. Therefore, life insurance companies should evaluate the impact of interest-rate risk and perform asset-liability management to prevent insolvency.
This study applies the concept of duration and K value (Barney 1997) to measure interest-rate risk and its impact on the operations of life insurance companies in Taiwan. The empirical analysis is conducted based on the financial data of life insurance companies in Taiwan during the period of 1998-2000. The empirical findings are listed as follows:
1.Interest-rate risk has a significantly negative impact on both investment return and ROE..
2.Interest-rate risk does not have significant impact on current ratio of the life insurance companies, but it is positively related to debt ratio.
3.Interest-rate risk does not have significant impact on either new contract growth rate or policy renewal rate, which indicates that the process of disintermediation does not happen in life insurance industry in Taiwan.
4.By investing in the long-term government bonds and corporate bonds and reducing the interest-rate sensitivity of policy loans、investment on real estates and fixed assets , life insurance companies may be able to increase their profits.
