Sequence of returns risk: why timing is everything

Two retirees can earn the very same average return and still end up worlds apart — one comfortable, one out of money. The reason is sequence of returns risk: when you are withdrawing from a portfolio, the order of good and bad years matters as much as the average. A crash in your first few years of retirement is the single biggest threat to making your savings last. Here is how it works and how to defend against it in 2026.

What is sequence of returns risk?

Sequence of returns risk is simple to state. It is the danger that the order of your investment returns — not just their long-run average — decides whether your retirement savings last. While you are still working and adding money, the order barely matters. Only your final compound return does. But the moment you flip from saving to spending the portfolio, the timing of a bad market becomes critical.

The reason is simple and unforgiving. When markets fall and you still need to withdraw income, you have to sell investments at depressed prices to raise that cash. Those sold-off units are gone — they are not there to recover when the market bounces back. A loss early in retirement is therefore made permanent by your withdrawals. That leaves a smaller base of capital to grow for the rest of your life. Get a great decade first and a bad one later, and you may never feel it. Get the bad decade first, and the same average return can leave you broke.

A sequence of returns risk example

Here is the cleanest way to see it. Take two retirees, Anita and Bruno. Each starts with $100,000 and withdraws $10,000 at the end of every year. Each experiences the identical three returns — +20%, 0%, and −20% — for an average of zero. The only difference is the order: Anita gets the bad year first, Bruno gets it last.

Anita Losses first: −20%, 0%, +20%

Year	Return	After withdrawal
Start	—	$100,000
1	−20%	$70,000
2	0%	$60,000
3	+20%	$62,000

Ends with $62,000

Bruno Gains first: +20%, 0%, −20%

Year	Return	After withdrawal
Start	—	$100,000
1	+20%	$110,000
2	0%	$100,000
3	−20%	$70,000

Ends with $70,000

Same starting balance, same withdrawals, same three returns, same zero average — yet Bruno ends with $8,000 more after just three years, purely because his good year came first. Now stretch this over a 30-year retirement with a real bear market. That gap is no longer $8,000. It becomes the difference between a portfolio that thrives and one that runs dry a decade early.

Why the order only matters once you withdraw

Here is the part that surprises people: if Anita and Bruno never withdrew a cent, the order would not matter at all. Multiplying $100,000 by 0.8, 1.0 and 1.2 gives exactly $96,000 no matter what sequence you use — multiplication does not care about order. Both would finish with the identical $96,000.

Withdrawals are what break that symmetry. Every dollar you pull out during a downturn is a dollar that can never recover, and selling more units at low prices accelerates the damage. That is why sequence of returns risk is fundamentally a decumulation problem — a retirement problem — not a saving problem. While you are still contributing, a rough early market is actually a gift, because you buy in cheaply before the recovery.

When sequence risk is highest: the retirement danger zone

The threat is not spread evenly across retirement. It is concentrated in the five to ten years on either side of your retirement date. Advisers often call this stretch the "retirement danger zone" or the "fragile decade." Two things line up badly in that window. Your portfolio is at its largest, and you have just started drawing it down. A steep drop then forces you to sell the biggest possible pile of assets at the worst possible prices.

The same percentage crash 15 years into retirement is far less dangerous. By then your time horizon is shorter, your balance is smaller, and you have already banked years of successful withdrawals. So the goal of sequence-risk planning is narrow and specific: get through that opening decade without being forced to sell into a deep decline.

How to protect against sequence of returns risk

You cannot control when a bear market shows up, but you can build a plan that survives a bad one early. Four defences do most of the work, and they stack well together.

Hold a cash wedge (or use buckets). Keep one to three years of spending in cash, a high-interest savings account, or a short GIC ladder. When stocks fall, you spend from that safe bucket instead of selling equities low. You refill it once markets recover. This is the heart of the bucket strategy.
Stay flexible and use guardrails. A withdrawal plan that bends survives. Trimming spending modestly in down years — skipping an inflation raise, deferring a big discretionary purchase — dramatically reduces the chance of running out. Flexible retirees can safely start at a higher rate than rigid ones.
Use a bond tent around retirement. Carry more bonds and cash in the years right around your retirement date, when sequence risk peaks. Then let your equity weight drift back up as you leave the danger zone. The extra ballast cushions an early crash exactly when it would hurt most.
Lean on guaranteed, inflation-linked income. Every dollar of spending covered by CPP, OAS, or a workplace pension is a dollar your portfolio does not have to produce in a down market. Maximizing that floor — including by delaying CPP — is one of the most powerful sequence-risk defences available to Canadians.

Sequence risk and Canadian retirees

Canadians face one extra wrinkle that U.S.-centric explanations miss: mandatory RRIF minimum withdrawals. Once your RRSP becomes a RRIF, the government requires you to withdraw a rising percentage every year, whether markets are up or down. In a bad year, that forced withdrawal can compel you to sell investments at a loss, precisely when you would rather leave them alone. It is sequence risk with a legal mandate attached.

A couple of levers help. Holding part of your RRIF in cash or short bonds means the mandatory minimum can come from the safe sleeve in a downturn (you can also take the withdrawal in-kind, moving securities to a TFSA or non-registered account rather than selling). Canada's guaranteed-income base helps too. CPP and OAS are both fully indexed to inflation. They give most retirees a built-in cushion that carries part of their spending, no matter what the market does. See our guides on converting your RRSP to a RRIF and the tax-efficient withdrawal order for how to sequence the accounts themselves.

Frequently asked questions

What is sequence of returns risk in simple terms?

It is the danger that the order of your investment returns — not just the average — decides whether your money lasts. Two retirees can earn the exact same average return over retirement. But the one who hits a market crash in the first few years can run out of money, while the one who hits the same crash later does fine. The difference is timing. Early losses are made permanent when you sell investments to fund withdrawals, so you have less capital left to recover when markets rebound.

When is sequence of returns risk highest?

It is highest in roughly the first five to ten years of retirement. This stretch is sometimes called the "retirement danger zone" or "fragile decade." That is when your portfolio is largest and you have just started withdrawing. A deep market drop then forces you to sell a big chunk of assets at low prices. A crash in your first or second year of retirement does far more lasting damage than the identical crash 15 years in, once your portfolio and time horizon are both smaller.

How do you protect against sequence of returns risk?

There are four main defences. First, keep one to three years of spending in cash or GICs, so you never have to sell stocks in a downturn (a cash wedge or bucket strategy). Second, stay flexible and trim withdrawals in bad years (the "guardrails" approach). Third, hold more bonds in the years right around retirement and let equities grow back later (a bond tent). Fourth, lean on guaranteed, inflation-linked income from CPP, OAS, and any pension, so your portfolio carries less of the load. Using a slightly lower starting withdrawal rate also builds in a margin of safety.

Does sequence of returns risk affect the saving years too?

Far less. While you are still contributing and not withdrawing, the order of returns barely matters. Only your average compound return and final balance do, because you are never forced to sell at a loss. In fact, a saver actually benefits from poor early returns, since they buy more shares cheaply before a later run-up. Sequence risk is fundamentally a withdrawal-phase problem. It only bites once you start drawing income from the portfolio.

How many years does sequence of returns risk last?

The acute risk is concentrated in the decade surrounding your retirement date. That means the last few working years and the first several retirement years, when your balance is at its peak. After about ten years of successful withdrawals through normal markets, your portfolio is usually well established. Later downturns, while unpleasant, are then unlikely to sink the plan. That is why so much retirement planning focuses on protecting that opening stretch.

Does the 4% rule account for sequence of returns risk?

Yes — it is the whole reason the rule lands near 4% rather than something higher. The original research deliberately tested withdrawals against the worst historical sequences, including retirements that began just before major crashes. A 4% starting rate survived even those bad-timing scenarios over 30 years. So the 4% rule is essentially sequence of returns risk baked into a single number. The catch is that it was built on U.S. history, which is why many Canadians shade a little lower.
