摘要

寿险公司出售带有退保期权的储蓄合同，允许投保人提前获得保证的退保价值。当利率上升时，这些退让期权向货币方向移动。因此，更高的利率提高了退保率，正如我们通过利用货币政策中看似合理的外生变化的经验证明的那样。本文利用一个校准模型，考察了利率上升期间退保期权对保险公司流动性和投资组合再平衡的影响。我们展示了资产出售是如何从保险公司的资产负债表动态中产生的，并探讨了它们与投资策略和退保价值保证的相互作用。

Life insurance convexity

Life insurers sell savings contracts with surrender options, which allow policyholders to prematurely receive guaranteed surrender values. These surrender options move toward the money when interest rates rise. Hence, higher interest rates raise surrender rates, as we document empirically by exploiting plausibly exogenous variation in monetary policy. Using a calibrated model, we examine the impact of surrender options on insurers’ liquidity and portfolio rebalancing during an interest rate rise. We show how asset sales result from insurer balance sheet dynamics and explore their interaction with investment strategies and surrender value guarantees.
