Longevity Basis Risk

A research project jointly commissioned by the IFoA and Life and Longevity Markets Association (LLMA) has developed a readily-applicable methodology for quantifying the basis risk arising from the use of population-based mortality indices for managing longevity risk.

Longevity basis risk arises because different populations, or subpopulations, will inevitably experience different longevity outcomes. This is a significant issue for those wishing to hedge longevity risk using a published mortality index – whether they be pension schemes, insurers, reinsurers, or banks.

This work will be beneficial to a wide variety of organisations and individuals, including pension schemes and their members as well as insurance companies, which write annuity business. These and other institutions which are exposed to, or would like to invest in, longevity risk will gain from a new methodology for quantifying risk related to longevity.

Phase 2: 2016/2017

The purpose of Phase 2 has been to:

  • determine the most relevant metrics for measuring longevity basis risk and hedge effectiveness;
  • apply the approach in Phase 1 to realistic worked examples based on appropriate data;
  • present a robust quantification of basis risk to third parties such as regulators; and
  • investigate the potential limitations of the time series processes.

    Phase 1: 2013/2014

    Phase 1 of this research focused on producing a methodology that could be used to quantify longevity basis risk and assess the level of risk reduction that might be brought about through the use of an index-based longevity hedge. It resulted in a framework that recognised the fact that different practitioners will have different portfolios, different volumes and histories of experience data, and different constraints of the models that they can use in practice.

    • Cass Event – New Thinking about Deferred Annuities

      Cass Business School, Executive Education Facilities 200 Aldersgate St, London EC1A 4HD
      21 June 2019

      Spaces available

      Our motivation for discussing this important subject comes from some exciting recent research which has analysed the impact of behavioural factors on the decision to purchase an annuity. This work has shown that behavioural factors can explain the well-known low demand for immediate annuities but this research also identifies an important opportunity in relation to deferred annuities (DA). The research suggests that these factors lead to positive incentives to purchase a DA and that, for longer deferred periods, a DA could be an attractive product for both consumers and insurers.
