What a 2008-style crash at retirement actually does
Everyone who retires with a stock-heavy portfolio eventually asks the same question: what if 2008 happens again — the year I stop working? The honest answer is more interesting than the fear. A crash at retirement is genuinely the worst-timed crash you can have, but what it does to a plan is specific, measurable, and worth simulating rather than dreading.
What 2008 actually was
In calendar 2008, US stocks (S&P 500, dividends included) returned −36.6%. But the rest of the row matters just as much: 10-year Treasury bonds returned +20.1%, cash earned +1.4%, and inflation was a mild +3.8%. A 60/40 portfolio lost about 13.9% — painful, not fatal. And 2009 followed with stocks up +25.9%. The 2008 experience for a diversified retiree was a deep one-year dent with a strong bond cushion and a fast partial rebound. Contrast 2022, when stocks fell 18.0%, bonds fell 17.8% at the same time, and inflation ran 8.0% — shallower headline losses, but nowhere to hide and every withdrawn dollar worth less.
Why timing is the whole story
Sequence-of-returns risk is the observation that two retirees can earn the same average return over 30 years and end up in completely different places depending on the order. The mechanism is withdrawals. A portfolio nobody touches recovers fully when prices recover — the same shares are still there. A retiree, though, sells shares every year to eat. Selling into a trough turns a temporary price decline into a permanent loss of shares, and those shares are the ones that would have done the recovering. A crash in year 25 lands on a portfolio that has already carried the plan most of the way; a crash in year one taxes every subsequent year of the plan.
A worked year one
Take a $1,000,000 portfolio at 60/40, spending $40,000 a year — the classic 4% starting point. Replay 2008 as the first retirement year: stocks fall to $380,700, bonds grow to $480,400, and after the $40,000 withdrawal the portfolio sits near $821,000. Nothing has failed — but next year’s $40,000 is now a 4.9% withdrawal rate, and the portfolio needs roughly +22% just to get back to its starting dollars while withdrawals continue. An all-stock retiree fares far worse: down to about $594,000 after the withdrawal, a 6.7% effective rate — deep in the territory where historical plans start failing. The same crash 25 years in barely moves either plan’s success rate. That asymmetry — the early years matter enormously, the late years barely at all — is sequence risk in one sentence, and it is why the first five to ten years of retirement are called the “fragile decade.”
What actually defends a plan
Three defenses show up repeatedly in the research. Bonds and cash held near the retirement date (a “bond tent”) mean the early withdrawals come from assets that didn’t crash — exactly what saved diversified 2008 retirees. Flexible spending rules that trim withdrawals a few percent after bad years keep share-selling out of the trough. And a lower starting withdrawal rate buys margin against any sequence. None of them show up in average-return arithmetic; all of them show up clearly in a Monte Carlo simulation, which is the point of running one.
Try it in Deorbit Plan
The Market assumptions panel’s Stress test section has a toggle — Replay the 2008 crash in one year — that forces one simulated year on every path to 2008’s actual returns. Choose the timing: the first year of retirement (the classic worst case), one random year per path, or a specific calendar year, and optionally replay the 2009 recovery the following year. The injected crash appears as a marker in the event lane under the Fan chart. Run it with and without the crash — or with the crash in year one versus year 25 — and compare success rates in Compare scenarios to see sequence risk in your own numbers.
