Housing affordability has been improving. It’s not enough and may not last much longer

RBC’s aggregate housing affordability index shows ownership costs consumed just over 50% of median household income in Q3 2025 (60% for single-detached; ~35% for condos). The Bank of Canada rate has been cut from 5.00% to 2.25% since June 2024 but remains above 2019's 1.75%; RBC and National Bank expect no BoC hikes in 2026 with increases likely in early 2027, although the Iran war and higher oil/bond yields could prompt earlier tightening. National Bank data: median-income households would need >10 years to save a minimum down payment in Vancouver (assuming saving 10% of pre-tax income), eight years in Toronto (minimum down ≈ $85k; implied mortgage ≈ $5,400/month or ~65% of pre-tax income), and shorter but rising timelines in Ottawa (4 years) and Quebec City (3 years).

Analysis

A geopolitical-driven oil shock is the most likely near-term accelerator of Canadian rates: sustained higher crude will lift global bond yields, feed into swap curves used to price fixed-rate mortgages, and compress the time window before central bank tightening. Mechanically, a persistent $8–$15/bbl upside in oil could push 2–10yr Canada yields 20–60bp higher inside 1–3 months, materially raising fixed mortgage quotes and repricing the large cohort of mortgages set to renew over the next 12–24 months.

Canadian banks have asymmetric exposure to this path. On the positive side, rising short- and mid-term yields expand NIMs quickly through variable-rate books and reset mortgage renewals; on the negative side, higher servicing costs, slower origination volumes and concentrated regional credit stress will bite. The net outcome will differ by balance-sheet mix: franchises with more variable-rate and commercial lending should outperform those overweight long-duration fixed-rate held assets.

Second-order winners include provincially exposed energy suppliers and regional landlords in energy-producing provinces as migration and wage spillovers re-anchor demand; losers are urban condo owners and REITs where liquidity and cap-rate sensitivity are highest. Construction-sector knock-on effects — material price volatility and labour reallocation to energy jurisdictions — will slow new supply, limiting any rapid correction in unit prices and making selective idiosyncratic opportunities more attractive than broad thematic bets.

Consensus currently prices gradual improvement in affordability; what’s missing is the interaction of a rate spike with the renewal cliff and regional migration flows. That creates an environment for relative-value trades across banks, REITs and fixed-income, where timing (6–12 months) and convexity to rates will determine winners.

Key Decisions for Investors

• Long RY (Royal Bank of Canada) equity — 6–12 month horizon. Size 2–4% NAV by buying stock or 12–18 month call spreads to capture NIM expansion from higher short- to mid-term yields. Target +15–25% upside if 30–80bp forward curve steepening; downside: -10% stop if 10y Canada yield falls >30bp or unemployment rises materially (credit stress).
• Pair trade: Long RY / Short XRE.TO (Canadian REIT ETF) — 3–9 months. Expect banks to reprice loans faster while REIT cap rates reprice wider on higher yields. Use 60/40 dollar-neutral weights; target 5–12% relative outperformance; stop-loss if spread tightens by 50% intraday or national 10y Canada yield drops >20bps.
• Short Canada 10-year duration — via sell futures or buy an inverse Canada government bond ETF — tactical 0–6 month hedge. Size to offset portfolio duration by 25–50%. Target 20–60bp yield rise; cap losses if yield falls >30bp (cut to flat).
• Selective long in well-capitalized regional energy-exposed mortgage lenders or small-cap landlords (research candidate list) — 6–18 months. These should capture provincial wage/migration tailwinds and avoid overheated urban condo exposures. Keep position small (1–2% NAV) and monitor regional employment and net migration data monthly; trim if national credit spreads widen >50bp.
