Why Understanding Risk Matters
Leveraged strategies can be attractive when rates are low and markets are rising, but the impact of a prolonged downturn, higher borrowing costs, or job loss can be severe. A realistic view of risk is essential before committing.
Market Risk and Sequence of Returns
Investment returns rarely arrive as a smooth average. A poor sequence of returns early in your plan can reduce your ability to recover even if long-term averages look acceptable on paper.
A large HELOC-funded portfolio that drops 30% in year two means you are paying interest on borrowed capital that is now worth far less — a hole that takes years of positive returns to escape.
Interest-Rate and Product Risk
HELOC and mortgage rates can rise faster and stay higher for longer than most people expect. Product terms, limits, and lender policies can also change over time.
A lender can reduce your available HELOC limit, change the rate structure, or require principal repayment — none of which are reflected in any calculator projection.
Behavioural and Cash Flow Risk
Seeing a large investment loan alongside a volatile portfolio can be stressful. Emotional decisions under pressure, such as selling low or abandoning a plan at the worst possible time, are among the most common and costly risks with leverage.
HELOC interest is also a real, annual cash obligation. In a year when your income drops or the market is down, you still owe the interest — and if you cannot pay it, it capitalises and compounds against you.
Using SmithCalc to Stress-Test Risks
You can use the calculator to model lower return assumptions, higher HELOC rates, and shorter time horizons to see how sensitive your projections are. If modest changes in assumptions dramatically change the outcome, proceed with caution.
Try these specific stress tests before making any decision:
- Set HELOC rate 3–4% higher than your current rate
- Cut your annual return assumption by half
- Shorten the projection to 10–15 years
- Switch to the Conservative risk profile
Risk-Focused FAQ
Should I still consider the Smith Manoeuvre if I have high-interest consumer debt?
In many cases, paying down high-interest consumer debt first is a higher priority than adding leverage. Discuss priorities with a qualified planner before layering in additional risk.
How conservative should my assumptions be?
Many people model a base case plus more conservative scenarios with lower returns and higher rates. If you would be uncomfortable with the conservative outcome, the strategy may not be suitable.
