    Direct vs. indirect rate impact

    ProductImpact TypeWhen You Feel It
    HELOCDirect (Prime + spread)Next billing cycle
    Variable mortgageDirect (Prime + spread)Next payment or trigger
    Personal line of creditDirect (Prime + spread)Next billing cycle
    Fixed mortgageIndirect (via bond yields)At renewal or new application
    Fixed personal loanIndirect (market trends)New applications only
    Credit cardsNone directlyLender discretion

    How the math works

    A 0.25% rate hike on a $300,000 variable mortgage adds approximately $40/month to the payment. A 1.00% hike adds ~$165/month.

    For a $50,000 HELOC at Prime + 1% (~8.20%), a 0.25% hike adds about $10/month in interest-only payments.

    Fixed-rate borrowers — how rates reach you

    5-year fixed mortgage rates track the 5-year Government of Canada bond yield plus a lender spread (~1.50%–2.00%). Bond yields move on Bank of Canada signals, but also inflation data, US Fed moves, and global risk events.

    Strategy in different rate environments

    EnvironmentBest Strategy
    Rates risingLock fixed; convert variable to fixed
    Rates flatModest savings on variable; fixed for certainty
    Rates fallingStay variable; defer locking fixed
    Highly uncertainSplit mortgage (50% fixed / 50% variable)

    Tip

    Use LoanIQ's scenario controls to model how a +/- 1% rate change affects your strategy.
