Fixed vs variable loans in a rate-cutting era

Last summer, we wrote a blog analyzing the costs and benefits of taking out a fixed or variable-rate loan. With the Bank of Canada (BoC) set to begin cutting interest rates soon, we reconduct the assessment considering today’s economic environment and different forward-looking scenarios.

Our hypothetical loans

As was the case last summer, the starting point for this analysis is two hypothetical loans – one fixed-rate, and one variable-rate. To complete the analysis, we needed to make some assumptions common to both:

• The mortgage amount is $500,000

• The terms of the loans are five years (five years being the most common term at FCC, regardless of interest rate type).

• Amortization is 25 years

• Payments are monthly

• Both are closed

• We do not make assumptions about the individual borrower’s creditworthiness

• For the variable-rate loan, the borrowing rate is prime plus 1.0%

• For the fixed-rate loan, the borrowing rate is the five-year Government of Canada bond yield plus 2.5%.

With our assumptions set, we can look at cash flow under different scenarios.

Our different economic scenarios

For our fixed rate loan, we use a rate of 6.25%. This is assuming a five-year government bond yield of 3.75% plus a spread of 2.5%. For our variable rate loan, we do not know with certainty what the path of variable rates – more specifically, the overnight rate set by the BoC – will be over the next five years. Here we rely on Moody’s Analytics for some guidance. Moody’s Analytics provides us with forecasts of where the overnight rate could move under different scenarios. Each scenario has a different probability of occurring.

1. Baseline scenario. This is the most likely scenario according to Moody’s. Under this scenario, the BoC cuts the overnight rate three times in 2024 given slowing inflation and weak GDP growth.
2. Upside scenario. Under this scenario, current geopolitical conflicts ease and/or end, and the supply side of the economy expands strongly. This supply side expansion offsets inflationary pressures, allowing the BoC to still lower the overnight rate in the latter half of 2024 (though at a more gradual pace than the baseline scenario).
3. Downside scenario. Under this scenario, current geopolitical conflicts worsen. The pullback in global trade deals a blow to the export-dependent Canadian economy. Consumer and business sentiment declines, causing inflationary pressures to slow. The BoC begins cutting rates almost immediately as the prospect of a recession are imminent.

The path of the overnight rate in the baseline and upside scenarios are similar, though again, the pace of cuts is more gradual in the upside scenario. In both these scenarios, by mid-2026 the BoC stops cutting rates once the rate hits 2.5%. The situation is quite different in the downside scenario: the overnight rate is cut in half by the end of 2024 (from 5.0% to 2.5%) and is further lowered in 2025 as the Canadian economy enters a recession. As the economy recovers, the BoC starts increasing the overnight rate. Movements in the overnight rate correspondingly cause movements in the prime rate (Figure 1).
