TY - JOUR T1 - A Key Rate Approach to Replicating Annuities with US Treasury Funds JF - The Journal of Fixed Income SP - 65 LP - 79 DO - 10.3905/jfi.2021.1.115 VL - 31 IS - 1 AU - Joseph R. Prendergast Y1 - 2021/06/30 UR - https://pm-research.com/content/31/1/65.abstract N2 - Prendergast (2021) develops a methodology that enables retail investors to structure annuities using commonly available US Treasury Exchange Traded Funds (ETFs). This article extends that methodology through the use of key rate durations. Back tests and stress tests show that the use of key rate durations substantially enhances the ability of the portfolio of ETFs to replicate an annuity in an environment where yield curves undergo a variety of slope and curvature changes over time.TOPICS: Fixed income and structured finance, exchange-traded funds and applications, statistical methodsKey Findings▪ Relative to using single durations, the use of key rate durations dramatically improves the ability of an annuity replicating portfolio to provide the desired annuity payments while achieving a zero-ending balance.▪ This article provides a means for retail investors, or their advisors, to design an annuity that is robust to interest rate changes without paying sizable fees to life insurance companies and other annuity providers.
