The beauty of such an income stream, otherwise known as an annuity, is that it goes on for as long as the person lives. It is helpful for those who need expensive long-term care at the end of life and, while there is a transfer from those who die young to those who live the longest, this kind of sharing is needed to reduce the pressure of paying for the old away from the young.
In the past, employer pensions were either paid by the firm, or employees were required to use their accumulated saving from their super scheme to buy an annuity from an insurance company. These annuities were fixed in dollar terms and lost value over time.
Those in the Government Superannuation Fund could take up to a quarter of their superannuation as a lump sum, with the rest as an inflation-adjusted annuity. While capital had to be given up to buy an income stream, it was better than worrying about the future, scrimping and saving, and then maybe dying early, leaving unintended bequests.
Those days have long gone for Generation-X. What will today's 48-year-old do with her KiwiSaver when she reaches retirement in 2031? How will she make her nest egg last?
There are real problems with expecting the private sector to come up with credible annuity products. Not least is the almost total unfamiliarity of New Zealanders with the concept of annuities, and a deep suspicion of the financial sector.
Other countries have a greater tradition of turning retirement savings into income for life. Nevertheless, all is not well in these countries. A recent UK report was very critical of the kind of annuities that people have been forced to buy with their tax-subsidised retirement savings.
It is time we listened, learned and debated these issues.
With KiwiSaver, New Zealand has done two things right that put us potentially well ahead. First, the individual is in control of his or her KiwiSaver saving, not the employer. We have also cleared the way to have a much fairer system.
Instead of subsidising the build-up of funds, we could have a well-designed subsidy for those who turn their savings pots into a modest additional income stream. Let's call this annuity "KiwiSpend". It might be offered by KiwiSaver providers, but would have certain characteristics. It could be inflation-proofed, with low fees, the same capital cost for women and men, inclusive of long-term care insurance and regulated by the Financial Markets Authority (FMA).
KiwiSpend would need to be carefully underwritten by the State with subsidies to make it attractive enough to achieve the social objectives intended. It won't make the costs of the coming tsunami of the old any less, but it could provide more security for Generation X and begin to share the costs more fairly.
