Analyst Warns of Potential 'Mortgage Renewal Cliff' in 2027 as Yields Rebound
Financial analyst Robert McLister suggests that a 'mortgage renewal cliff' may return in 2027 as Canada's five-year government yield rebounds toward four per cent. If rates rise significantly, mortgage payments on average homes could increase by approximately $232 monthly, stress test requirements would tighten, and home prices might fall. However, fewer borrowers will be exposed to this shock compared to previous cycles due to thinning renewals, and economic constraints may limit the duration of any rate hikes.
Financial analyst Robert McLister has suggested that the term "mortgage renewal cliff," originally coined in 2023 to describe the impact of COVID-era borrowers facing higher rates upon renewal, may become relevant again in 2027. This potential resurgence is linked to Canada’s five-year government yield, which has recovered 63 per cent of its decline from October 2023 to April 2025 and is currently pointing toward four per cent.
If the five-year yield breaks above four per cent, it could test its post-2008 financial crisis high of 4.42 per cent. A 75 basis point increase in the five-year yield would likely coincide with multiple Bank of Canada rate hikes. Under such a scenario, mortgage payments on an average $668,351 home—assuming a 30-year amortization period and a 20 per cent down payment—would jump by approximately $232 a month if leading rates rose by 75 basis points.
The bank regulator’s mortgage stress test rate could also climb from 5.6 per cent to 6.35 per cent or more under a significant rate hike scenario. Qualifying for an average home under these higher stress test rates would require at least another $8,000 to $9,000 in income. Borrowers renewing mortgages taken out in 2022, which averaged in the high threes, would face rates in the fives in 2027, leading to double-digit percentage increases in payments.
However, the scale of exposure differs from previous cycles. Renewals are expected to thin out sharply from the latter half of 2027 onward compared with the past few years. Additionally, historical data indicates that hiking cycles have lasted just over 2.5 years on average, with the central bank raising rates by roughly 2.75 percentage points. Statistics Canada data show that real disposable incomes have fallen from their pandemic peak, creating budgetary stress for homeowners facing renewals or adjustable rates.
Real estate accounts for 20 per cent of Canada’s economy. Consequently, if buyer confidence wanes, listings could accumulate, sales might weaken, and home prices could fall. The combination of falling real disposable incomes and rising costs could drive up mortgage arrears. While some analysts suggest recommended buffers for payment planning, the broader economic context suggests that constraints may limit the duration of any future rate hikes.
