Sequence of returns risk: the biggest risk after early retirement

Here is a fact that quietly terrifies anyone who understands it: two people can retire with the exact same corpus, earn the exact same average return over their retirement, follow the exact same withdrawal rule, and yet one dies wealthy while the other runs out of money. Nothing separates them except luck, specifically the order in which their good and bad years arrived. That is sequence of returns risk, and it is the single most dangerous force in the first decade of any early retirement.

The reason it is so misunderstood is that we are all taught to think in averages. "Equity returns about 11% over the long run," we say, and we plan as if we will receive 11% every year like a salary. But you never actually earn the average. You earn a jagged, unpredictable sequence, up 20% one year, down 25% the next, and when you are pulling money out of the pot, the sequence matters far more than the average.

Why the order flips from friend to enemy

While you are still building your corpus, a crash early on is almost a gift. You have little invested to lose, and every SIP you make during the downturn buys units cheaply that soar when the market recovers. A young accumulator should almost cheer a bear market.

The moment you retire and start withdrawing, that logic inverts completely. Now a crash early on is a slow-motion disaster. To fund your spending you are forced to sell units at depressed prices, which means you sell more of them to raise the same rupees. Those units are gone, so when the market recovers, it recovers on a permanently smaller base. You have locked in the loss and handed away the recovery.

Picture two retirees who both average 9% over 30 years. One hits a brutal three-year slump right at the start; the other hits the identical slump near the end. The first can be broke decades before the second, from the same average return, purely because of when the pain landed.

This is also why early retirees are more exposed than traditional ones. A 40-year-old has a 45-year retirement, so there are simply more early years in which a badly-timed crash can do lasting damage, and less institutional support to fall back on. It is a big reason FIRE plans lean cautious.

How to defend yourself

You cannot control when a crash arrives, but you can build a plan that survives a bad one:

• Hold a cash or short-debt buffer so that in a downturn you spend from that instead of selling equity at a loss. This is the whole logic of the bucket strategy, and it is the most effective single defence.
• Use a slightly lower withdrawal rate, so there is margin to absorb a rough start.
• Stay flexible. Trim spending in bad years rather than mechanically withdrawing the same inflated amount into a falling market.

The FIRE Planner lets you run your plan through good, expected and weak markets side by side, so you can see how fragile or robust it is before your money, rather than your spreadsheet, finds out.
