Sequence of Returns Risk

Risque lié à la séquence des rendements in French

Quick definition

Sequence of returns risk is the danger that poor market returns arrive early in retirement, just as withdrawals begin. Two retirees can earn the same average return, in a different order, and end up in wildly different financial shape.

Same average return, very different retirements

For decades of saving, what matters is roughly the average return you earn. The moment you start spending from the portfolio, a second variable takes over: the order in which those returns arrive. A bad stretch early in retirement, combined with withdrawals, can permanently damage a plan that the exact same returns, arriving in a different order, would have left comfortably intact.

The mechanism is simple. When markets fall and you sell anyway to fund spending, you sell more units at depressed prices. Those units are gone; when the recovery comes, it compounds on a smaller base. Losses plus withdrawals lock in damage that later gains cannot fully repair.

The mirror-image example

Take two retirees who each start with $500,000 and withdraw $25,000 at the start of every year. Their portfolios earn the identical three annual returns, -15%, -5% and +30%, but in mirror-image order. The average return is the same for both, about 3.3% per year.

Two retirees, same returns in opposite order (rough figures, illustrative only)
End of yearRetiree A: -15%, then -5%, then +30%Retiree B: +30%, then -5%, then -15%
Year 1$403,750$617,500
Year 2$359,800$562,900
Year 3$435,300$457,200

What the numbers say

After only three years, retiree A sits about $22,000 behind retiree B, despite identical withdrawals and an identical average return. Retiree A sold into two down markets, so the +30% rebound had less to work with. Stretch the same effect over a 30-year retirement with a real bear market up front, and the gap becomes the difference between a plan that lasts and one that runs dry.

Why savers are mostly immune

Sequence risk is a retirement problem, not an investing problem. During accumulation, with no withdrawals, the order of returns does not change the destination at all: $500,000 left untouched through -15%, -5% and +30% ends at about $524,900 in either order, to the dollar. Someone contributing regularly actually benefits from early declines, since dollar-cost averaging buys more units while prices are low.

The danger zone is the transition: roughly the last few working years and the first several years of retirement, when the portfolio is at its largest and withdrawals begin. Planners sometimes call it the retirement risk zone.

How retirees defend against it

You cannot control what markets do in your first retirement years, but you can control how exposed your spending is to them. The common defences all follow one idea: avoid selling depressed assets to buy groceries.

  • A cash wedge: keep 1 to 3 years of planned spending in cash, high-interest savings or GICs, and draw on it in bad markets so investments are left alone to recover.
  • Flexible spending: skip the inflation raise or trim withdrawals after a losing year. Small cuts made early have outsized effects on how long the money lasts.
  • A guaranteed income floor: deferring CPP and OAS, or buying a partial life annuity, covers fixed expenses with income no market can touch, shrinking the withdrawals that sequence risk acts on.
  • Bond allocation: a meaningful bond allocation dampens the depth of early losses, which matters more in this window than at any other point in your investing life.
  • One more year: delaying retirement, or working part-time through a downturn, skips the most damaging withdrawals entirely.

The 4% rule connection

The famous 4% rule from US retirement research is, at heart, a sequence-of-returns artifact: the "safe" starting withdrawal rate was set by history's worst orderings of returns, not by average ones. Guidance in that tradition is approximate and much debated, but its underlying lesson stands: a retirement plan should be built to survive a bad order of returns, not just a bad average. Our Retirement Payout Calculator lets you test how long a portfolio lasts under different return and withdrawal assumptions.

In Canada

Canadian retirees meet sequence risk with a particular twist: RRIF rules force a minimum withdrawal every year, so registered money cannot simply sit untouched through a bear market. Two features soften this. The minimum is a percentage of the account's value, so the dollar amount falls automatically after a bad year, and withdrawals can be made in kind, moving investments to a TFSA or taxable account without selling them.

On the other side of the ledger, Canada's guaranteed income layer, CPP or QPP and OAS, both indexed to inflation, gives every retiree a sequence-proof floor, and deferring those benefits strengthens it.

Worked example

Nadia retires at 65 with $600,000 and plans to draw $30,000 per year. She keeps $60,000, two years of withdrawals, in GICs and a high-interest account, and holds 40% bonds in the rest. Markets drop 18% in her first retirement year. Instead of selling depressed equities, she spends her cash wedge and skips her planned inflation raise. Two years later, with markets recovered, she refills the wedge from the portfolio. Her investments took the same hit as everyone else's, but her plan never converted a temporary loss into a permanent one.
