Abstract:
BACKGROUND : Many retirees in South Africa face the challenge of either outliving their
retirement savings or living below their means. Studies suggest a ‘safe’ withdrawal rate of
between 4% and 5%, which is below the average fund size-weighted drawdown rate of
approximately 6.66%.
AIM : To provide a scientific basis for the success rate of a ‘hybrid’ retirement strategy, whereby
a retiree invests a proportion of their savings in a life annuity and the remaining proportion in
a living annuity, to increase the success rate for South African retirees.
SETTING : Historical asset class returns (equities, bonds and inflation) for South Africa were
sourced for the period 1900–2020.
METHOD : Bootstrap sampling of historical asset returns was employed to simulate 10 000
random scenarios to investigate the success rate of various compositions of the ‘hybrid’
retirement strategy.
RESULTS : The success rate of all ‘hybrid’ portfolio compositions is significantly greater than
the success rate of a pure living annuity when the withdrawal rate is less than 8%.
CONCLUSION : In a South African context, a ‘hybrid’ retirement portfolio increases the
probability of success for retirees withdrawing less than 8% from their portfolio – which
constitutes approximately 50% of the current annuatised population – and may increase the
inheritance of a retiree’s heir.
CONTRIBUTION : Where other studies have focussed solely on the success rate of a living
annuity, we have shown that a ‘hybrid’ retirement strategy increases a South African retiree’s
likelihood of retiring successfully when the withdrawal rate is less than 8%, which is
approximately 50% of the annuatised population.
