2026 Interest Rate Scenarios: If the Bank of Canada Cuts Rates, Will Affordability Reach a Turning Point or Face a Second Surge?
A recent RBC report clearly outlines a baseline scenario: the Bank of Canada will hold rates steady throughout 2026. However, market expectations for a rate-cutting cycle have never fully dissipated. This article uses official RBC data to simulate affordability evolution under two distinct rate paths, revealing the fundamental shift from a "price-driven" to a "payment-driven" market, and warns of the potential double-edged sword effect of rate cuts.
📌 Introduction: The Interest Rate Question Hidden Behind "National Improvement"
On March 31, 2026, RBC released its latest housing affordability report. The headline data appears optimistic: the national affordability indicator fell to 52.4% in Q4 2025, marking the eighth consecutive quarter of improvement, down 10.6 percentage points from the peak of 63% in late 2023. However, the report subtly signals a concerning trend: the pace of improvement has become "weaker and more sparse."
Over the past two quarters, the national indicator has only declined by an average of 0.4 percentage points, far less than the 1.6-point average seen in the previous year and a half. RBC attributes this slowdown to regional divergence—Vancouver and Toronto account for most of the national improvement, while affordability in other markets (like Montreal and Quebec City) continues to worsen.
But the report contains a key assumption often overlooked: the Bank of Canada will hold rates steady throughout 2026. RBC writes, "We expect the BoC to remain on the sidelines through 2026, meaning only price declines in some markets and continued household income growth will ease ownership cost burdens."
This means that in RBC's baseline scenario, affordability improvement relies solely on two factors: price declines in specific markets (mainly Vancouver and Toronto, with high inventory) and household income growth (which is already slowing). Yet, market expectations for a rate cut persist. If the central bank unexpectedly pivots in 2026, what would happen to Canada's housing market? Would affordability finally reach a true turning point, or would it trigger a second surge due to overheated demand?
Based on official RBC data and CMHC's renewal outlook, this article simulates affordability evolution under two distinct rate paths, providing a multi-scenario decision-making framework for homebuyers, investors, and policymakers.
📊 Baseline Scenario Key Data
- Policy Rate: 2.25% (unchanged)
- National Affordability Indicator: 52.4% (Q4 2025)
- Improvement Pace: Average of 0.4 percentage points over the last two quarters, vs. 1.6 points previously
- Improvement Drivers: Solely reliant on price declines in select markets + household income growth
The RBC report clearly states that without further policy easing, the "recovery period" for affordability improvements is nearing its end. The national indicator is likely to stagnate around 52%, and the market will enter a stalemate characterized by regional divergence. Stable mortgage rate trends will make payment stress tests a core consideration for buyers, with the 2026 market forecast leaning toward regional differentiation rather than a broad-based recovery.
Direct Quote from RBC: "We expect the BoC to remain on the sidelines through 2026, meaning only price declines in some markets and continued household income growth will ease ownership cost burdens."
Interpretation: In the baseline scenario, the scope for affordability improvement is very limited. If rates remain unchanged through 2026, the national indicator will likely oscillate around 52%, with regional divergence intensifying. Buyers should abandon hopes of a "national recovery" and focus on local market supply-demand dynamics and SNLR changes.
📐 Rate-Cut Scenario Assumptions
Assumptions: The Bank of Canada cuts the policy rate by a cumulative 75 to 100 basis points in 2026. Consequently, 5-year fixed mortgage rates fall by approximately 1 percentage point. Current 5-year fixed rates are around 4.5%-5%, dropping to the 3.5%-4% range post-cut.
Core Logic Shift: The market transitions from being "price-driven" (relying on price declines) to "payment-driven." Lower rates directly reduce mortgage principal and interest payments, immediately improving affordability without waiting for price adjustments.
| Indicator Dimension | Baseline (Rates Unchanged) | Rate-Cut Scenario (75-100 bps cut) |
|---|---|---|
| Affordability Improvement Path | Slow improvement reliant on price declines + income growth | Immediate improvement driven by lower monthly payments |
| Affordability Sensitivity | Quarterly improvement of 0.2-0.4 ppts | One-time improvement of 4-5 ppts (e.g., from 52.4% to 47%-48%) |
| Transaction Volume | Sluggish or hovering at lows | Moderate recovery as sidelined buyers re-enter |
| Price Trend | Modest declines in Toronto/Vancouver, increases in Quebec | Stabilization in high-inventory markets, rebound risk in tight-supply markets |
| Renewal Pressure | 1.15M renewals face payment jumps | Rate cuts partially offset payment jumps, easing pressure |
💰 Interest Rate Sensitivity Calculation Example
Using a baseline national affordability indicator of 52.4%, assume the 5-year fixed mortgage rate falls by 1 percentage point (from 4.8% to 3.8%). With a 20% down payment, 25-year amortization, and median household income unchanged, the monthly payment burden would decrease significantly. According to RBC's indicator formula, a 1-point drop in rates could directly lower the indicator by about 4 to 5 percentage points (exact impact depends on the price-to-income ratio).
Example: 52.4% → approx. 47%-48%. This improvement far exceeds the 0.4-point average seen over the last two quarters, offering substantial relief to sidelined buyers. The RBC report emphasizes that rate cuts would directly lower ownership costs (with mortgage payments being the largest component), particularly benefiting renewing households and first-time buyers.
If Bank of Canada rate cut expectations materialize, the 2026 housing market forecast would shift toward a moderate recovery: higher sales and price stabilization in some markets. However, the magnitude and pace of cuts are critical—small, gradual cuts are more conducive to a smooth transition, while large, rapid cuts could amplify market volatility.
Historical Lesson: Accommodative monetary policy is often accompanied by rapid asset price appreciation. During the 2020-2021 pandemic period, ultra-low rates ignited a nationwide price surge, driving the affordability indicator from around 40% to a peak of 63%. While rate cuts lower the cost of new loans, the actual experience for renewing households depends on price trends. A combination of rate cuts and price rebounds could strain the cash flow of highly leveraged households again.
📊 Affordability Evolution Under Two Paths
- Path A (Moderate cuts + Supply response): Rate cuts activate demand, new supply comes online simultaneously, prices rise moderately, and affordability continues to improve → a true turning point.
- Path B (Rapid cuts + Supply lag): Demand is released in a concentrated manner, markets with tight inventory see prices surge first, the affordability indicator worsens again after a temporary improvement → a second surge.
RBC warns that if rate cuts cause buyers to flock to the market, rising prices could partially or fully offset the payment relief from lower rates, turning an anticipated affordability "turning point" into "secondary deterioration." While falling mortgage rate trends lower the cost of new loans, the actual experience for households with renewals depends on price trajectories. Payment stress tests must account for worst-case scenarios.
📦 Renewal Volume & Rate Jump Magnitude
According to CMHC data, Canada will experience a peak in mortgage renewals in 2026, with approximately 1.15 million mortgages coming up for renewal—a significant portion of the outstanding mortgage stock. Most renewing households will transition from ultra-low rates of 1.5%-2% secured during the pandemic to current levels of 4.5%-5% (or 3.5%-4% even after a 75-100 bps rate cut).
Payment Jump Calculation: For a $500,000 mortgage balance, a rate increase from 2% to 4% raises the monthly payment (25-year amortization) from approximately $2,120 to $2,640—an increase of about 25%. If rates are cut to 3.5%, the payment would be about $2,500, still an 18% increase.
📊 Significant Regional Disparities
- High-Price Markets (Toronto, Vancouver): Ample inventory (months of inventory >3.5) can absorb renewal-related supply shocks, with downward price pressure likely persisting.
- Mid-Price Markets (Montreal, Quebec City): Tight inventory makes renewing households more vulnerable to cash flow stress. If rate cuts trigger a demand surge, these markets face the dual risk of accelerating prices combined with renewal payment pressure.
- Balanced Markets (Calgary, Edmonton): Affordability has normalized, making the renewal shock relatively more manageable, though local employment and income trends still warrant attention.
A key uncertainty for the 2026 market forecast is the timing overlap between the renewal peak and any rate cuts. If cuts occur before the peak, they could preemptively hedge against payment jumps. If cuts are delayed until after the peak, the risk of short-term defaults increases.
💡 Three Core Conclusions
1. Under the baseline scenario, the momentum for improvement is exhausted.
RBC clearly states that without further policy easing, the "recovery period" for affordability is nearing its end. The national indicator will likely stagnate around 52%, with the market entering a stalemate of regional divergence.
2. Rate cuts would fundamentally shift the logic driving affordability.
The market would transition from being "price-driven" to "payment-driven," with the affordability indicator potentially improving by 4 to 5 percentage points in one go—much faster than via price declines. However, the magnitude and pace of cuts are critical, with small, gradual cuts favoring a smoother transition.
3. Beware of the double-edged sword effect where "price rebounds offset payment relief."
While rate cuts activate demand, they could also trigger a second price surge in inventory-tight markets, causing any affordability "turning point" to vanish quickly. Historical experience shows that accommodative monetary policy is often accompanied by rapid asset price appreciation; risks must be proactively managed.
In a nutshell: Bank of Canada rate cut expectations are the most critical variable for the 2026 housing market. They will directly determine whether affordability reaches a true turning point or faces a second surge due to overheated demand. Homebuyers and investors should conduct multi-scenario payment stress tests, closely monitoring central bank meeting signals and SNLR changes. The 2026 housing market will feature "rate-driven regional divergence"—the more uncertain the rate path, the more cautious the decision-making must be.

Primary Source: RBC Economics, "Canada's Housing Affordability Improvement Is Weaker and More Sparse," released March 31, 2026. Author: Robert Hogue, Assistant Chief Economist.
Renewal Data: Canada Mortgage and Housing Corporation (CMHC), 2025 Mortgage Industry Outlook.
Rate Sensitivity Calculation: Simulation by HousingAI based on RBC's indicator definition. Affordability indicator = ownership costs (mortgage principal + interest + property taxes + utilities) divided by median pre-tax household income. Assuming property taxes and utilities are constant, a 1 percentage point drop in rates can reduce mortgage principal and interest payments by approximately 10%-12%, leading to a 4-5 percentage point improvement in the indicator (exact impact depends on loan size and income ratio).
