WealthSequence of returns risk — the silent retirement trap
| Retiree | Starting capital | Average return (30 yrs) | Year 1 return | Ending capital |
|---|---|---|---|---|
| Retiree A | $1M | 7% | positive years first | $2.5M |
| Retiree B | $1M | 7% | -30% | $0 |
Two retirees with identical $1M starting capital and identical 7% average return over 30 years end up in opposite places — purely because of when the -30% year happened.
1. What is sequence risk?
Even with identical average returns, the order of returns massively affects your capital if you withdraw money.
Example: 2 retirees with $1M, 7% average return over 30 years, but reversed order. One ends at $2.5M, the other at $0 — simply because of a -30% year 1.
2. Why critical for FIRE
You withdraw 4% annually per Trinity rule. If market drops 40% year 1, capital drops to $600k while you withdraw $40k — 6.7% of capital, unsustainable.
| Strategy | Key figure |
|---|---|
| Cash buffer | 2-3 years of expenses in cash or GICs, at 5% interest |
| Variable withdrawal (Guyton-Klinger) | Drop to 3.5% instead of 4% if market falls 20% |
| Pension bridge | Delaying CPP to age 70 increases benefit by 42%; combined with OAS at 70, up to $30-40k/yr |
| Conservative allocation | Shift to 60/40 or 50/50; costs 5-6% return instead of 7-8% |
Each strategy trades some upside (interest lost on cash, lower withdrawal, delayed pension income, lower average return) for protection against a bad first-five-years sequence.
3. Strategy 1: 2-3 year cash buffer
Keep 2-3 years of expenses in cash or GICs before retirement (5% interest). In a crash, live off cash without selling stocks.
4. Strategy 2: variable withdrawal
Instead of fixed 4%, adjust by performance. If market drops 20%, withdraw 3.5% instead. Guyton-Klinger guardrails method.
5. Strategy 3: pension bridge
In Canada, delaying CPP to age 70 increases benefit by 42%. Combined with OAS at 70, can generate $30-40k/yr pension income.
6. Strategy 4: conservative allocation at retirement
Move from 100% stocks to 60/40 or 50/50 as you approach FIRE. Less volatility = less sequence risk. Cost: 5-6% return instead of 7-8%.

Frequently Asked Questions
Which year is riskiest?
First 5 years of retirement. After 10 positive years, risk drops dramatically.
Should I abandon FIRE in a bear market?
No. Adjust withdrawals (Guyton-Klinger) or temporarily resume work. FIRE remains valid long-term.
Does cash buffer lose to inflation?
Slightly. But savings from avoiding a crash sale far outweigh 2-3 years inflation loss.
How do I know I’m ready?
Test: if your capital drops 30% tomorrow, can you live 3 years without selling? If yes, ready.
