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.
