What are mortgage Trigger Rates?

As inflation continues to send prices higher, the Bank of Canada (BoC) has been raising interest rates in an effort to get things back under control. So far this year, the prime rates of most lenders have more than doubled, from 2.45% to 5.45%. This dramatic leap has prompted public concern about mortgage borrowers reaching their “trigger rate.”

If you have a fixed-rate mortgage, nothing will change for you until it’s time to renew. But if you have a variable-rate mortgage, these rate hikes have a direct and immediate effect – and you could be at risk of reaching your trigger rate. Not all variable-rate mortgage holders have to worry about trigger rates, however. Read on to learn about whether you might be affected, and what to do if you are.

Two Triggers

There are actually two triggers at risk of being pulled: your trigger rate and your trigger point. To understand these terms, we need to first take a look at how variable-rate mortgages work.

Each mortgage payment is made up of two parts: principal and interest. The principal is the portion of your payment that goes toward your balance owing, while interest is the bank’s fee for letting you use their money.

When you have a variable-rate mortgage, your interest rate is defined relative to your lender’s prime rate. For example, your mortgage rate might be something along the lines of prime minus 1.20%. When the prime rate goes up, your mortgage rate goes up along with it – increasing the amount of interest you need to pay each month.

To help keep things predictable, many lenders offer variable-rate mortgages with fixed payments. Instead of changing the size of your payment every time the prime rate changes, your lender will continue to collect the same amount and allocate a larger or smaller portion of your payment to interest.

If you have a variable-rate mortgage with adjustable payments, you have nothing to worry about. But if your variable-rate mortgage has fixed payments, rising interest rates can cause trouble. As your mortgage rate rises, a larger portion of your payment is put toward interest and a smaller portion of your payment goes toward principal. The trade-off for not increasing your payment is that it will take longer to pay off your mortgage.

What is the trigger rate?

Your trigger rate is the point at which your regular payment is no longer enough to pay all of the interest you’ve accrued since your last payment. In other words, your entire mortgage payment is going to interest and none of it is going to your principal. This is the first of two triggers you can reach.

When you reach your trigger rate, what’s actually being “triggered” is an increase to your balance owing. Because your regular payment is no longer enough to cover the cost of borrowing, the entire payment is applied to interest. Any amount still owing is termed deferred interest and added to your balance to be paid sometime down the road.

When you’ve reached your trigger rate, you’ve stopped paying off your mortgage and started borrowing more. Those in the know call this “negative amortization.”

What happens when you reach the trigger rate?

While no intervention is necessary when you reach your trigger rate, your lender or mortgage broker will likely give you a courtesy call to let you know your payments are no longer big enough to pay down your mortgage. They’ll explain your options and help you reach an informed decision about how to proceed.

Just because you can carry on with the same monthly payment you’ve been making, however, that doesn’t mean you should. With every month that passes, you’ll owe more and more money on your home. Your rising balance will demand a rising interest payment, making the problem worse as time goes on.

If it’s at all possible, increase the size of your monthly mortgage payment well before you reach your trigger rate. Otherwise, you risk reaching an even worse threshold: your trigger point.

What is the trigger point?

Your trigger point is the time at which you can no longer carry on with the same monthly payment you’ve been making. 

There isn’t a single overarching rule that defines the trigger point. Rather, your trigger point will be spelled out in your mortgage contract.

A common trigger point is the time when the balance owing on your mortgage exceeds the amount you borrowed in the first place. For example, if you took out a $500,000 variable-rate mortgage and reached your trigger rate after paying the balance down to $490,000, the interest amount your payment didn’t cover would start being added back to your balance. You would reach your trigger point if and when your balance got back up to $500,000.

Your trigger point could also be described as a percentage of your property’s value. For example, you could reach your trigger point when your mortgage balance exceeds 100% of your home’s appraised value.
