HELOC Rate Spread Narrows to Prime Plus 0.5% to 1.0% in 2026
The margin lenders charge above Prime on revolving credit has compressed. A HELOC that would have carried Prime plus 1.25% eighteen months ago now prices at Prime plus 0.5% to 1.0%. That's a 25 basis point drop on the upper end, and it matters more than most people realize when the credit is being used to invest.
What changed and when
WealthNorth tracked the shift through September 2026. Where the competitive range previously ran from Prime plus 0.5% to Prime plus 1.25%, the ceiling has fallen. The tightest pricing stayed where it was. The expensive end moved down.
This isn't a rate cut. Prime hasn't changed. What changed is the spread, the markup each lender adds to Prime when they set the rate on the revolving portion of a HELOC. That spread is negotiated between lender and borrower, and it has narrowed across the market. The borrower with average credit and a standard application who would have been quoted Prime plus 1.25% a year ago is now seeing Prime plus 1.0% or better.
Why the ceiling matters more than the floor: most people don't get the floor. The advertised best rate goes to the applicant with strong credit (typically 720+), a metropolitan property, minimal other debt, and a loan-to-value ratio under 65%. That describes a small share of the market. The pricing the majority of borrowers actually receive sits closer to the middle or top of the range. When that top number drops by 25 basis points, it's a real cost reduction for real people.
What this means for readvanceable structures
A readvanceable mortgage pairs a declining-balance mortgage with a revolving HELOC. As the mortgage pays down, the HELOC limit rises by the same amount, keeping total credit constant. The structure turns a routine principal payment into borrowing capacity you can redeploy. If that redeployed capital goes into a non-registered investment account, the interest on the HELOC becomes tax-deductible. This is the mechanics underneath the Smith Manoeuvre™.
The cost of running that structure is the spread between the mortgage rate and the HELOC rate. When the HELOC rate drops, the spread narrows, and the drag from carrying the borrowed amount shrinks. A 25 basis point reduction on a $50,000 invested balance is $125 per year. That's after-tax dollars, so the equivalent pre-tax income required to cover it is roughly $175 to $200 depending on your marginal rate.
Over a typical mortgage amortization, the cumulative effect compounds. The savings aren't incidental. They change the math on whether the strategy clears the return hurdle.
What to do if you already have one
If you opened a readvanceable mortgage more than 18 months ago, your HELOC rate was set then. It doesn't automatically adjust when the market spread narrows. You're still paying the rate you agreed to.
Call the lender. Ask what rate applies to your HELOC today. If it's outside the current range, if you're still at Prime plus 1.25% or higher, ask what it would take to reprice it. Some lenders will adjust on request if the file is in good standing. Others require a formal application or a switch to a current product. The conversation costs nothing, and the answer determines whether you're leaving money on the table.
If the lender won't move and the rate difference is meaningful, compare what a switch would cost. The penalty to break the mortgage portion, the legal fees, any discharge or setup costs. Do the arithmetic. A quarter-point spread reduction on $80,000 over 15 years is several thousand dollars. The break-even on a $1,200 switch cost is approximately six years.
This applies whether you're running the Smith Manoeuvre™ or simply using the HELOC for renovations, tuition, or liquidity. The interest you're paying is the interest you're paying. When the market rate drops and your rate doesn't, the gap is real money.
If you're considering a readvanceable structure now, the current spread makes it cheaper to operate than it was a year ago. That doesn't make it appropriate for everyone, leverage still carries risk, and the tax deduction only helps if you have income to shelter, but the cost side of the equation has improved.
If you want to walk through whether this applies to your situation, or whether repricing makes sense given your current terms, that's the kind of conversation I have with clients regularly. Start here: https://indebtonpurpose.ca/contact
