中文摘要

本文討論恐慌指數(VIX)的變動,對於壽險業投資型保險業務的影響。國內的投資型保險商品,佔整體壽險業收入15%左右,為壽險公司第三大保費收入來源,此項業務深受金融市場變化所影響;惟現有文獻鮮少討論恐慌指數變動對金融機構業務層面衝擊的主題,本文藉此補充現有研究的不足。研究期間為2008年至2015年,以美國及臺灣兩地的恐慌指數(VIX_CBOE及VIX_TW)作為解釋變數,分為整體壽險業及個別壽險公司兩部分進行實證。實證結果發現:(一)就整體壽險業來說,VIX_CBOE及VIX_TW對投資型保險商品保費收入及投資型保險保費收入占總保費收入之比率,具有顯著負向影響,顯示在恐慌心理蔓延時,投資人將減少投資型保險之投入;在控制相關總體變數的情況下,當VIX_CBOE(或VIX_TW)每上升一單位,將導致整體壽險業投資型保險保費收入每月平均減少8.89(或11.79)億元新臺幣。而相對而言,VIX_CBOE比VIX_TW具有較強之解釋能力。(二)個別公司之投資型保單保費收入,亦受恐慌指數負向影響,惟影響程度不同:規模較大或為外商壽險公司者,受影響較小;屬於金控旗下者,則受影響較大。綜合來看,恐慌指數對於整體壽險業之解釋能力,較對於個別公司為高,顯示VIX較適合做為解釋整體市場變動因子的角色。

英文摘要

This article explores the effect of the volatility index (VIX) to life insurance industry in Taiwan, focus on the influence of the premium income of investment -linked products. Our sample period is 2008 to 2015, and the VIX indices published by Chicago Board Opt ions Exchange (VIX_CBOE) and Taiwan Futures Exchange (VIX_TW) are employed as explanatory variables to discuss two major issues. The first part analyzes the impact of VIX changes on the whole industry, and the second focuses on individual companies. The major findings include: (1) For whole life insurance industry, VIX_CBOE and VIX_TW have significant negative impact on the premium income of investment -linked products, and also the ratio of investment -linked product premium income over total insurance premium. It shows when the value of VIX higher, the investment -linked product premium income will be significantly declined. When the VIX_CBOE (or VIX_TW) increases 1 unit, the premium income of investment -linked products of whole industry will decrease 0.889 (or 1.179) billion New Taiwan dollars each month on average under controlled relative macroeconomic variables. VIX_CBOE has stronger explanatory power than VIX_TW. (2) For individual companies, the VIX_CBOE and VIX_TW still have negative impact on the investment -linked products premium income, moreover, the influence is smaller for large scale companies and foreign ones, but more severe for the those under financial holding companies. The explanatory power of VIX on whole industry is significant higher than on individual companies, indicating that VIX is more suitable to play as a factor for explaining the variation of whole industry.
