Imagine you are reviewing a client’s portfolio transition plan during an annual review. You observe that the client has targeted a corpus depletion age of 80, based on standard actuarial life expectancy tables. However, you note the client’s family history and health metrics suggest a high probability of reaching 95. As an analyst, realizing your model relies on a static mortality assumption is a red flag; you are effectively discounting the probability of a ‘ruin scenario’ where the client’s purchasing power vanishes while they are still active and requiring liquidity.
Longevity risk is the distinct financial hazard of outliving one’s assets. In the Indian context, where traditional social security frameworks are limited and healthcare costs for the elderly often track well above CPI inflation, this risk is exacerbated. To mitigate it, financial advisers must move beyond simple linear projections and incorporate ‘buffer assets’ and diversified income streams. This includes utilizing products like Immediate Annuities or systematic withdrawal plans (SWPs) that provide longevity hedges by pooling mortality risk with other participants.
From a valuation perspective, ignoring longevity risk is akin to ignoring a terminal value in a DCF model; it misrepresents the total resource requirement. When modeling a retirement corpus, an analyst should conduct a sensitivity analysis on the withdrawal rate.
For example, if a client intends to withdraw 6% of their initial capital annually, the sequence of returns risk—the risk of poor market performance early in the retirement phase—compounded by the potential for an extended lifespan, creates an unsustainable depletion curve.
By shifting the model to assume a 95-plus age horizon, you may find that the client must reduce current discretionary spending or increase their equity allocation to ensure the real rate of return remains sufficient for an additional fifteen years.
Practical mitigation also involves tactical asset allocation changes as the client ages. While de-risking into debt is standard, one must ensure a portion of the portfolio remains in inflation-hedging assets like equity or real estate investment trusts (REITs). This ‘bucket strategy’ approach, where the initial years of retirement are funded by liquid, low-risk assets and the later years are supported by growth-oriented assets, creates a robust defense against both inflation and excessive longevity.
Ultimately, your recommendation must shift from a ’target sum’ mindset to an ‘income replacement’ mindset, ensuring that the portfolio’s structure remains resilient even if the client significantly outperforms actuarial life expectancy.1

Sequence of returns risk is the danger that a major market downturn occurs early in the retirement distribution phase, which forces the liquidation of assets at low prices, thereby permanently reducing the portfolio’s growth potential. ↩︎
