Familiarity over value: the hidden cost of Canada’s mortgage habits

Canadians disproportionately use brand-specific mortgage searches while U.S. consumers search generically — U.S. generic 'mortgage rates' queries are roughly 15x the volume of Canadian generic searches, yet Canadians search big-bank brand rates (e.g., 'RBC mortgage rates') more than U.S. equivalents. This brand dependence helps explain why Canada’s largest banks have increased residential mortgage share over the past decade, limiting uptake by credit unions and fintechs and weakening competitive pressure that would lower rates and improve products. The piece is a cautionary view that consumer inertia plus incumbents' advertising, distribution and regulatory advantages create modest negative outcomes for consumer welfare, though it is unlikely to move markets immediately.

Analysis

Incumbent banks are sitting on an economic moat that looks behavioral rather than structural: small persistent frictions in consumer search and dealer visibility can translate into 5–15 bps of effective mortgage spread stickiness that compounds over time. For a large bank, that magnitude delivered through mortgage balances and cross-sell can move EPS by mid-single-digit percentages over a 12–24 month window without any change to credit quality or macro inputs.

Second‑order effects amplify the incumbents’ advantage: funding cost asymmetry (deep retail deposits and wholesale programmes) makes it expensive for challengers to scale even if they match pricing, while distribution lock‑in raises acquisition costs for fintechs and credit unions. Expect acceleration of partnership models (fintechs selling through banks), selective M&A of niche lenders, and concentrated advertising spend — all of which preserve market share absent an exogenous shock.

Regulatory and technological catalysts are the primary paths to reversal: consumer‑facing price transparency tools or targeted switching regulations could compress incumbent premiums within 12–36 months; conversely, slower fintech customer acquisition curves imply a multi‑year incumbency tailwind. The asymmetric outcome is clear — the upside for incumbents is steady and realized through cashflows, while the downside is binary (regulatory/structural reset) and therefore should be priced accordingly into multiples.

Key Decisions for Investors

• Overweight RY (Royal Bank) — buy RY common stock with a 6–12 month horizon. Size 2–4% of portfolio; target 12–18% total return driven by NIM resilience and market‑share stickiness. Risk: regulatory intervention or an outsized mortgage credit shock; set a 12% stop‑loss and take profits at 15–20%.
• Relative trade: long RY / short RKT (Rocket Companies) — 12 month pair to capture incumbents’ structural distribution advantage vs. digital origination platforms. Expect 15–25% relative outperformance if consumer inertia persists; risk is faster digital adoption or better-than‑expected scale for platforms, cap relative loss at 20% of notional.
• Income trade: sell covered calls on RY (3–6 month expiries, strike ~10% above spot) to monetize entrenched premium while retaining upside. Generates 4–8% yield over the period in stagnant market conditions; downside limited to equity decline below strike plus foregone upside if a structural reversal occurs.
• Event hedge: buy protection on Canadian bank basket (put spread on RY/BNS/TD) with 9–18 month expiry to guard against regulatory/regime change risk. Cost is modest vs one‑off binary loss; pay up if your book is levered to mortgage assets or if you anticipate policy headlines within 12 months.
