The Bank of Canada Rate Your Mortgage Actually Follows Isn't the One You're Watching
The Bank of Canada raised rates seven times in 2022, and most homeowners felt nothing. Their mortgage payment stayed flat. The rate that moved was the overnight rate, which the Bank uses as a tactical lever to steer the economy month to month. Variable-rate borrowers saw their payments climb. Fixed-rate borrowers, who had locked in at 3.89% three years earlier, saw nothing until renewal day arrived.
That gap between policy moves and household impact is the structural reason most renewal shocks happen. The overnight rate is a short-term signal. The neutral rate is the floor.
The neutral rate, sometimes called R-star, is the interest rate at which the economy operates at full employment with inflation stable at the Bank of Canada's 2% target. The Bank estimates it based on demographics, productivity trends, and capital flows. As of mid-2024, the Bank of Canada pegged the neutral rate at 2.25% to 3.25%, up from the 1% to 3% inflation control range it maintained before the pandemic. That shift matters more for your mortgage than any single rate cut.
Why the Neutral Rate Sets the Floor
Bond markets price five-year Government of Canada bonds based on where they expect rates to settle over the next half-decade, not where they sit this month. Mortgage lenders price fixed rates by adding a spread, typically 150 to 200 basis points, to those bond yields. If the bond market believes the neutral rate is 3%, a "normal" five-year fixed mortgage sits near 4.5% to 5%, not 2.5%.
The overnight rate can sit below neutral when the Bank is trying to stimulate growth, or above neutral when it is fighting inflation. Both are temporary positions. The neutral rate is the anchor. When the overnight rate is 4.5% and the neutral rate is estimated at 3%, the policy stance is restrictive. The overnight rate will eventually fall toward 3%, where the economy balances.
Homeowners renewing in 2026 often assume that rates will return to the 2020-2021 lows once inflation is under control. They will not, because the neutral rate itself has moved. Sub-2% fixed mortgages disappeared because the underlying conditions that allowed ultra-low rates reversed: aging populations stopped parking capital in safe assets, globalization stopped suppressing costs, and capital flows shifted.
What This Means for Renewal Strategy
If you are renewing a five-year fixed mortgage in 2026 and the overnight rate is 2.25%, that looks expensive compared to the 1.79% you locked in back in 2021. But with the neutral rate estimated at 2.25% to 3.25%, the overnight rate is at or slightly below the bottom of the neutral range. The Bank is no longer restrictive. It is close to equilibrium. A borrower waiting for rates to fall further is waiting for the overnight rate to go below neutral, which would signal a weakening economy and rising unemployment. This is possible but unlikely.
Compare the rate you are offered to the neutral rate plus a typical mortgage spread. If five-year bond yields are trading at 3.2% and your quoted rate is 4.8%, that is a 160-basis-point spread, which is inside the historical norm. The rate is not cheap. When the neutral rate is 3%, this is what mortgages cost.
Variable rates offer a different calculus. When the overnight rate sits well above the neutral range, say, 4.5% against a 3% neutral estimate, a variable rate gives you exposure to the rate cuts that will eventually bring policy back to neutral. When the overnight rate is already near neutral, that downside protection shrinks. The gamble is no longer "will rates fall," but "will they fall below neutral and stay there."
The Structural Shift No One Mentions
Statistics Canada reported in September 2026 that mortgage debt servicing costs remained elevated even as the overnight rate fell from its 2023 peak. The reason is structural. Renewals from 2021 are rolling into a different neutral-rate environment. The policy rate is lower than it was in 2023, but higher than the pre-pandemic floor. It will only return to that floor if the neutral rate itself falls again.
The overnight rate is weather. The neutral rate is climate. Watching the weather tells you whether to bring an umbrella today. Watching the climate tells you whether to buy a house with a furnace or an air conditioner. Renewal decisions are climate decisions. Most borrowers treat them like weather.
