This article explains how the new stress test rule will lower your mortgage approval maximum. Then we run the numbers to show you how potential interest rate increases will affect your monthly mortgage payments.

The CMHC Mortgage Stress Test

To get approved for a home mortgage in Canada, all homebuyers need to pass the CMHC stress test. The stress evaluates how well you can manage financial shocks to your mortgage situation such as reductions in your household income or increases to your mortgage rate.

To pass the test, you need to prove that you can afford your monthly mortgage payments at the benchmark rate, which is increasing from 4.79% to 5.25% on June 1st, 2021. Let’s see how this 0.46 percentage point increase affects Kelowna homebuyers.

Right now the Bank of Canada is afraid that Canadian households will not be able to afford their monthly mortgage payments if interest rates go up, which could lead to a wave of mortgage defaults similar to the 1980s

How the Benchmark Rate Increase Affects Buyers

Before the June 1st, 2021 change, a Kelowna homebuyer with a household income of $125,000 paying 20% down could afford a maximum home price of $671,292 at the benchmark rate of 4.79%. When the benchmark rate rises to 5.25% on June 1st, the same homebuyer with a $125,000 income would be able to afford a maximum purchase price of $645,753; a decrease in the maximum purchase price of $25,539 or ~4%*.

The Benchmark Rate for Uninsured Mortgages

Your mortgage is considered uninsured if your down payment is less than 20%. For uninsured mortgages, CMHC calculates your stress test using the higher number of either 5.25% or your mortgage rate plus 2%.

How Interest Rate Increases Affect Your Payments

While many economists are predicting low rates for the long-term, we’ve seen the 5-year fixed rate in Canada rise to 19.2% in the 1980s, which forced many households into mortgage default.

But for the purpose of illustration, let’s see how increases in the mortgage rate will affect Kelowna’s 2020 and 2021 homebuyers.

As we can see in the table above, each percentage point increase in the fixed 5-year rate translates into an increase in monthly payments of approximately $328 to $420, and an increase in total interest of $98,445 to $126,038.

Due to the magnitude of outstanding global debt, it’s highly unlikely rates will ever rise this fast again; it would be far too punishing for western economies. It’s also worth mentioning that interest rates typically rise by half or quarter percentage points.

But it’s always important to prepare for unforeseen events.
