Natural delta gamma hedging of longevity and interest rate risk
The paper presents closed-form Delta and Gamma hedges for an- nuities and death assurances, in the presence of both longevity and interest-rate risk. Longevity risk is modelled through an extension of the classical Gompertz law, while interest rate risk is modelled via an Hull-and-White process. We theoretically provide natural hedg- ing strategies, considering also contracts written on di erent genera- tions. We provide a UK-population and bond-market calibrated exam- ple. We compute longevity exposures and explicitly calculate Delta- Gamma hedges. Re-insurance is needed in order to set-up portfolios which are Delta-Gamma neutral to both longevity and interest-rate risk.
