The Conventional Focus on Corpus
For most of our working lives, the primary financial goal is accumulation. We are taught to save diligently, invest systematically through SIPs, and watch our retirement corpus grow. The logic is simple and sound: the larger the nest egg, the more comfortable
the retirement. This has led to an almost singular focus on the target number—that magical figure we believe will secure our future. All energy is channelled into maximising this lump sum through disciplined saving and long-term investment growth. While building a substantial corpus is undeniably the foundation of a secure retirement, it represents only the first half of the financial journey. The second half, the decumulation or withdrawal phase, requires a completely different mindset and strategy.
The Hidden Danger: Sequence of Returns Risk
The single biggest threat to a retirement portfolio is something called 'sequence of returns risk'. This is the risk that you will face poor or negative market returns in the first few years after you retire. Why is the timing so important? When you are accumulating wealth, a market downturn is a buying opportunity. But when you are withdrawing money to live on, a downturn can be devastating. If you are forced to sell assets in a falling market to cover your living expenses, you are 'locking in' those losses. This means you have to sell more units of your investments to get the same amount of cash, which permanently depletes your capital. This reduced capital then has a smaller base from which to recover and grow when the market eventually bounces back.
A Tale of Two Retirees
Imagine two friends, Anand and Brijesh, who both retire with an identical corpus of ₹2 crore. Both plan to withdraw ₹8 lakh (4% of their corpus) in their first year of retirement. In Anand's first year of retirement, the market delivers a strong 15% return. His portfolio grows to ₹2.28 crore before his withdrawal, leaving him with ₹2.20 crore. In contrast, Brijesh retires just as the market enters a downturn, and his portfolio loses 15% in the first year. His ₹2 crore corpus shrinks to ₹1.7 crore. After he withdraws his necessary ₹8 lakh, he is left with just ₹1.62 crore. Even if both Anand and Brijesh achieve the same average return over the next 20 years, Brijesh is at a significant disadvantage. His portfolio was damaged so early in retirement that it may never catch up, and he faces a much higher risk of running out of money.
Strategies to Manage Post-Retirement Risk
The good news is that you are not helpless against this risk. Several strategies can help insulate your retirement income from market volatility. One popular method is the 'bucket strategy'. This involves dividing your retirement corpus into three distinct buckets. The first holds one to three years of living expenses in very safe, liquid assets like cash or short-term fixed deposits. This is your income source during a market downturn, so you are not forced to sell equities at a loss. The second bucket holds three to seven years of expenses in a balanced mix of debt and hybrid funds. The third, long-term bucket holds the rest in growth assets like equity mutual funds, designed to beat inflation over the long run.
Rethinking Your Withdrawal Plan
Beyond the bucket strategy, adopting a flexible withdrawal plan can make a huge difference. The traditional '4% rule'—withdrawing 4% of your initial corpus each year, adjusted for inflation—can be too rigid in volatile markets. A dynamic withdrawal strategy is often more resilient. This means you might withdraw a smaller percentage (say, 3%) after a year of poor market performance, and a slightly larger percentage (perhaps 5%) after a year of strong returns. This flexibility allows your portfolio more breathing room to recover from downturns. The goal is to avoid selling assets at the worst possible time. This total-return approach, which considers the whole portfolio as a source of funds rather than just relying on dividends or interest, is a more robust way to plan your retirement cash flow.
