Ep 179 - How to Stress Test Your Retirement Plan in 2026 (Before It Breaks)
Most retirement plans look fine - until inflation, markets, taxes, and ‘real life’ hit. In this episode of Your Retirement Planning Simplified, Joe Curry explains how to stress test your retirement plan in 2026, why Monte Carlo projections can create false confidence, and how guardrails help you make calmer, tax-smart retirement income decisions when markets get volatile.
Key Takeaways
A retirement plan isn’t “set it and forget it.”
Your plan must evolve as markets, inflation, tax rules, and your life change. Otherwise it’s a snapshot, not a strategy.
Assumptions become outdated almost immediately.
The issue isn’t that you used “bad” assumptions - it’s that inflation, interest rates, and returns don’t behave in straight lines.
Sequence of returns matters more than long-term averages.
Poor returns and high inflation early in retirement can do more damage than people realize, even if the long-term average looks fine.
Monte Carlo is useful, but it’s not a plan.
It may show a “success rate,” but it doesn’t account for how you’ll behave emotionally when markets drop or uncertainty spikes.
Guardrails create a decision framework before things get scary.
By setting triggers and responses ahead of time, you reduce emotion and make small adjustments early instead of big ones later.

Stress Testing Your Retirement Plan in 2026: How to Build a Plan That Bends Without Breaking
Most retirement plans look great on paper - until real life shows up.
Markets move. Inflation surprises. Tax rules change. And your own life evolves in ways you can’t predict. That’s why retirement income planning in Canada can’t be treated like a one-time project. A plan you created a few years ago might still be “technically correct,” but that doesn’t mean it’s prepared for what 2026 and beyond might bring.
A retirement plan isn’t a masterpiece you lock in and follow for 30 years. It’s a living document—one that needs updates and flexibility built in.
Why Assumptions Don’t Age Well
Assumptions aren’t the enemy. They’re necessary. The real issue is that the day after you set them, they start drifting away from reality.
Think about the last decade: inflation surged to levels we hadn’t seen in a long time, interest rates climbed and then started coming down, and markets swung hard in both directions. Even when long-term returns look strong, the ride is never a straight line.
And here’s the part many people underestimate: it’s not just how much return you get—it’s when you get it. If you face low returns and high inflation early in retirement, it can put real pressure on your plan, regardless of what the “30-year average” says.
Longevity Changes the Whole Math
People are living longer—and staying healthier longer. That means retirement isn’t 15–20 years for many Canadians anymore. It could easily be 30–40 years.
That’s not meant to scare you. It’s meant to highlight why flexibility matters. Longer retirements require more planning around sustainable withdrawals, tax-efficient investing, and income strategies that can adapt over time.
Why Monte Carlo Can Create False Confidence
Monte Carlo analysis is a helpful tool because it runs thousands of possible market outcomes. It’s better than a straight-line projection.
But it still has a problem: it doesn’t account for behaviour.
It doesn’t tell you how you’ll react when your portfolio drops 20% or 30%. It doesn’t capture the emotional decisions people make when uncertainty hits. And those decisions can matter just as much as the math.
So the better question isn’t “Will this plan work forever?” It’s: How does this plan adapt when things change?
Guardrails: A Practical Way to Reduce Emotion
Guardrails are a way to pre-plan your responses before markets get scary.
For example, you might set a target withdrawal range. If withdrawals rise above a certain level, that’s a signal to make a small adjustment early—rather than a painful adjustment later. Or you might use a plan-based approach where you monitor your probability range and only make changes if you move outside your “green zone.”
The point isn’t perfection. It’s preparedness.
Because the best retirement plan isn’t one that predicts the future—it’s one that bends without breaking.
