Taiwan has an ageing population, with more people in the concern of not having sufficient income stream during retired life. This study investigates the ageing issue through socioeconomic perspectives. It is recommended that apart from low interest-bearing term deposits, Interest-Sensitive Annuity is the most suitable solution for countering longevity risk. Through case studies, it has been found that 1, due to Annuity Puzzle sentiment, term depositors will continue to invest in Interest-Sensitive Annuities, regardless of the low interest rate environment. 2, Interest-Sensitive Annuity investors are as risk-averse as term depositors, implying that they do not necessarily choose the surrender option upon expiry. 3, due to customer sentiment, the Interest-Sensitive Annuity policy fees charged are inversely correlated to customers¡¦ willingness to invest. 4, by selling low-commission products, namely one- and two-year Interest-Sensitive Annuities through bancassurance channel, insurance companies enjoy the benefit of low cost capital and are able to reduce interest spread risk through efficient investments. Moreover, customers have their retirement needs covered while insurance salespeople of different channels are able to meet respective sales targets. It is therefore shown that Interest-Sensitive Annuities have the following benefits. For investors, it is the product type that best meets their needs. For insurance salespeople, they enjoy a diverse and complete product portfolio and for insurance companies, it maximizes operation efficiency. Unfortunately, after the termination of one- and two-year Interest-Sensitive Annuities on the market, insurance company capital costs have been negatively impacted, with retirement and longevity risks unsatisfied and insurance salespeople having less products to choose from. It is suggested that the regulator considers re-introducing one- and two-year Interest-Sensitive Annuities, using Risk-Based Capital as a complement in monitoring insurance companies.

銀行保險通路近年來成為壽險公司主要保險通路之一，因此壽險公司在銀行保險通路所承擔的風險逐漸加重。近年來金融市場處在一個低利環境下，儲蓄型商品（例如：利率變動型年金）為銀行定存商品替代品之一，故，儲蓄型商品逐漸成為銀行保險通路吸引銀行客戶的主力商品。因此可知，壽險公司對銀行保險通路，尤其是，儲蓄型商品之風險管理日漸重要。主管機關為了確保壽險公司清償能力，近年來針對儲蓄性商品制定相關策略，希望藉由限制儲蓄型商品之銷售比例，加強壽險公司之風險管理，防止壽險公司因為銷售過多儲蓄型商品而造成財務負擔。 本研究以商品組合互補效果的概念達到風險管理，其中儲蓄型商品以利率變動型年金作代表；傳統型商品以傷害保險與定期壽險作代表。本研究使用現金流量分析法，透過壓力測試和敏感度分析，嘗試在不同情境下，尋找一個規律，並簡易設算銀行保險通路下主力商品之最適銷售比例。 模擬結果發現，傳統型商品可有效彌補儲蓄型商品帶來的風險；而銷售比例之訂定，應該依照壽險公司在不同壓力測試、可控制之利差之下，設算出最適可銷售比例；只要壽險公司將其資本額大小、預計總保費收入、預計銷售商品、宣告利率策略及各項利率關係在不同情境下作設算，即可求出在不發生盈餘虧損下，商品組合之最適銷售比例。 另外本研究也發現，傷害保險與利率變動型年金保險之替代效果，比定期壽險與利率變動型年金保險佳，因此可作為商品組合搭配之參考。 本研究貢獻在於透過簡易的測試，設算出實際數值，可望提供壽險公司在資產負債管理方面的新思維。 / In recent year, baccasurance has become one of the major channels for life insurance companies. Therefore, adding up the risk the baccasurance channel imposes, life insurance companies has undertaken heavier risks. Due to the fact that the interest rate has been comparably low for the last ten years, more and more consumers choose to buy deposit insurance (EX：interest sensitive annuity ) the substitute for periodic deposit. As the vital product in baccasurance channel, managing the risk of deposit insurance become more and more important. This study adopted the idea of mixing products to achieve complementary effect, so that the risks might be better managed. Interest Sensitive Annuity was chosen to represent deposit-oriented products, and Injury Insurance and Periodical Annuity Life Insurance to represent traditional commodities. The method used for analysis was Cash Flow Test, in which stress test and sensitivity analysis were included, through which the researcher attempted to induce a rule from various situations and compute out the optimum ratio of the major products on the bancassurance channel. The simulation result showed that traditional insurance products are able to compensate the deposit-oriented insurance, and the maximum percentage this product accounts for should be computed abiding by to controllable interest gain under various kinds of stress tests, for which the companies need to take into account its capital size, total premium, products being promoted, declared interest rate, and interest rates to help simulate all kinds of situations. It is possible to compute out the optimum ratio for the products when the goal surplus more than or equals to zero. In addition, it was also found that injury insurance is a better substitute for interest sensitive annuity insurance than term life insurance. It is suggested that insurance companies to carefully gauge the respective proportion for Periodical Annuity Life Insurance, Injury Insurance, and Interest Sensitive Annuity Insurance. Finally, it is hoped that the numerical number tested out by the current study provides insurance companies a new insight in asset liability management.

保險法第146條之4規範國外投資總額最高不得超過各該保險業資金45%，而2014年修正增列保險業依保險法規定投資於國內證券市場上市或上櫃買賣之外幣計價股權或債券憑證之投資金額，可不計入其國外投資限額。且因我國市場長期處於低利環境，壽險業即大量以台幣作為融資貨幣買入國外高利率環境下之標的貨幣進行利差交易，本研究擬以經濟資產模型進行資產與負債之模擬，衡量壽險公司的經濟資本與清償風險。 依據現行壽險公司資金運用決定投資之標的，並以Cox-Ingersoll-Ross (1985)模型模擬國內外短期利率，在無拋補利率平價說下建立匯率模型，以Heston (1993)隨機過程描述資產的變化，並考量壽險公司投資策略決定投資比率，再加入資產之相關性進行模擬；以與壽險公司投資連結之利率變動型年金為商品，加入各項風險因子進行負債價值模擬，諸如死亡率、解約率等因子；資產與負債皆在風險中立測度下以蒙地卡羅法進行模擬10,000次，探討公允價值下壽險公司之清償能力。 而現行清償能力指標為資本適足比率，但此標準下尚無法完整考慮各風險之相關性，本研究除考量資本適足比率中風險資本總額，亦加入經濟資本進行分析，可得以下結果： I.現行RBC風險資本總額介於VaR 99.5%與95%所計算之經濟資本間。 II.當匯率波動度與國外投資比例增加時，經濟資本亦將顯著增加。 III.隨國外債券投資比例增加，風險資本總額增加之幅度亦會加速成長。 IV.利率變動型年金商品宣告利率之擬定將顯著影響公司面臨之違約風險。 / The amendment of Article 146-4 of Insurance Act extended the overseas investment ceiling in 2014 that the International Bond was not included to be counted in overseas investment. Since we have been suffering from the low interest rate for a long time, life insurance industry often uses carry trade to enlarge their earnings. In this paper, the investment targets are chosen on the basis of the current life insurance industry. We simulate the short-term interest rate based on Cox-Ingersoll-Ross (1985) model, establish the exchange rate model by Uncovered Interest Rate Parity, and use Heston (1993) model to simulate stochastic process of assets. Then we consider the life insurance industry’s investment strategy to determine the investment ratio and also import the asset correlation into our models. The interest sensitive annuity policies we used to evaluate the liabilities are linked with life insurance companies’ investment. Some risk factors are also been considered, such as mortality, surrender rate and other factors. Through Monte Carlo simulations by 10,000 times, we analysis the life insurance companies’ solvency under risk neutral measurement by using Risk-Based Capital and Economic Capital. The results show that： I.Risk-Based Capital is between Economic Capital calculated by VaR 99.5% and 95%. II.When the volatility of exchange rate and overseas investment ratio increase, the Economic Capital will also increase significantly. III.With the increase in the proportion of foreign bond investment, the increase in the Risk-Based Capital will accelerate the growth. IV.The declaring interest rate of interest sensitive annuity policy will significantly affect the default risk faced by the life insurance company.
