Big Six impaired loans hit $37.5 billion: what 'manageable' means for your bank

The Big Six hold capital buffers roughly double their regulatory minimums, with Common Equity Tier 1 ratios running between 12.5% and 13.5%. That cushion is what Morningstar DBRS is pointing to when it calls $37.5 billion in gross impaired loans "manageable." The word choice matters. It doesn't mean painless. It means the system can absorb it without fracturing.

Gross impaired loans across Canada's largest banks have reached levels not seen since well before the pandemic, nearly tripling from the cyclical troughs of 2021 and 2022. The Office of the Superintendent of Financial Institutions classifies a loan as impaired once it's 90 days past due or otherwise in significant credit distress. The $37.5 billion figure, reported in recent quarterly filings, reflects what always happens after interest rates move sharply: the failures arrive 12 to 24 months later.

The Bank of Canada's tightening cycle peaked in 2023. By mid-2026, the delayed consequences are showing up as Stage 3 assets, loans officially in default or significantly credit-impaired, on the banks' balance sheets. The sharpest increases have come from two places: commercial real estate, particularly office and retail properties facing both high rates and structural demand shifts, and unsecured consumer credit like credit cards and auto loans.

The mortgage cliff didn't break the system

Residential mortgages, the largest component of Canadian household debt, remain relatively stable. Delinquency rates are low by historical standards. That stability is not accidental. It reflects the way Canadian households prioritize debt. When borrowers face payment shock, the reality of renewing a five-year fixed mortgage originated in 2020 or 2021 at rates now two to three percentage points higher, they cut spending elsewhere first. Credit card balances go unpaid. Auto loans slip. The mortgage stays current.

This creates a bifurcated credit crisis. The household is under stress, but the home is protected. For the banks, that means losses are concentrating in unsecured portfolios, where recovery rates are lower but exposure is smaller. The commercial real estate book is a different story. Office vacancy rates in major cities have not recovered to pre-pandemic levels. Retail landlords face ongoing pressure from e-commerce. High borrowing costs turn projects that penciled at 3% into projects that don't pencil at 7%. Commercial real estate impairments reflect permanent shifts in how tenants use office and retail space, not temporary swings in the credit cycle.

What provisions tell you

Banks began increasing their Provisions for Credit Losses two years ago, anticipating this trend. PCLs are the forward-looking estimate of how much capital the bank needs to set aside to cover expected defaults. The fact that impaired loans are rising while bank solvency remains intact is evidence the provisioning worked. It hit earnings. The rising impaired loans did not force the banks to shrink their balance sheets or stop lending.

Capital regulation exists for this moment. OSFI's requirements, which force banks to hold substantial equity buffers even in good times, are designed to let banks absorb losses without cutting lending or triggering systemic risk. The CET1 ratios above 12.5% mean that even if impaired loans rise further, the banks can cover the losses and keep operating normally.

The employment picture has helped. Canada's job market through mid-2026 has remained stable enough to prevent a catastrophic spike in residential defaults. If unemployment rises sharply, the current "manageable" assessment could change quickly. The Bank of Canada's timing on rate cuts becomes critical. Move too slowly, and more households reach the breaking point. Move too quickly, and inflation reaccelerates, forcing another tightening cycle.

For individual borrowers, $37.5 billion in impaired loans is thousands of personal insolvencies. For the financial system, it's a stress test the architecture was built to pass.
