台灣保險業另類投資工具風險控制與監理研究

Abstract

台灣壽險業的利差損問題持續存在，但若想要進一步開放新投資項目，應先檢視新投資工具之特性以及研究對應之保險監理規範之修訂。\n本研究針對國外另類投資進行實證分析，考慮風險與報酬之間的抵換關係(Trade-Off)，以Rockafeller and Uryasev (2000)以及Campbell,Huisman and Koedijk (2001)提出之投資組合模型，建立平均值-風險 值(Mean-Value-at-Risk)之 效 率 前 緣 和 平 均 值-條 件 風 險 值(MeanConditional Value-at-Risk)之效率前緣，探討另類投資對投資組合效率的影響，並檢視相關保險監理規範的適宜性。\n實證結果顯示不同資產類別(Assets Class)之間的相關性低，加入另類投資的標的能夠提升投資組合的效率，因此建議可以開放一些另類投資的項目，或是設定門檻進行監理。

Recently, many insurance companies in Taiwan increased their investments in foreign countries substantially due to the inadequacy of domestic investment markets. Some insurers started or have been preparing to invest in emerging alternative investment tools such as private equity funds and hedge funds. However,there is a trade-off between return and risk. In this study we utilized the methods developed by Rockafeller and Uryasev (2000) and Campbell, Huisman, and Koedijk (2001) to conduct risk-return analyses for the insurance companies who are interested in alternative investments. Our approach extends the traditional Mean-Variance approach by introducing value at risk (VaR) and conditional VaR as risk measures. We found that the correlations among asset classes were low and alternative investments could enhance the investment efficiency of insurance companies. We suggest loosening some regulations accordingly.
