Mortgage arrears are rising unevenly, and that is the part worth reading closely. A national arrears rate blends millions of loans into one number. The stress sits in specific pockets, and the pockets tell you who is likely to struggle next, and how lenders will react.
The starting point is simple. Some loans are falling behind at a higher rate than the rest of the mortgage market. That is the public line from the latest coverage, and it matches what lender and ratings agency reporting has shown for some time. This piece is about what sits behind it. It does not rest on one borrower’s story.
Mortgage arrears are a cohort story, not a national one
Arrears are usually measured as loans 30 or 90 days past due. Both measures tend to climb first in groups that carry thin buffers. Four cohorts are the usual suspects.
- Recent vintage loans. Borrowers who bought or refinanced near the peak of prices carry the biggest debts against the least equity. They also never had the benefit of years of repayments or wage growth.
- High loan-to-value ratio (LVR) borrowers. Less equity means fewer options. Selling or refinancing out of trouble is harder when the loan is close to the property’s value.
- Investors. Rising rates hit cashflow directly, and rent does not always keep pace. Investors usually have other options, such as selling, so their arrears can stay contained.
- Regional and outer-suburban borrowers. Smaller local economies, softer price growth and fewer buyers can leave less room to exit.
The cohorts overlap. A recent, high-LVR, first-home buyer in an outer suburb is the profile lenders watch most closely.
Why recent loans are the pressure point
Here is the mechanics in plain English. A loan written when rates were low was assessed with a buffer, but the buffer was set against income at that time. Since then, repayments have risen and living costs have too. Wage growth has helped, but not evenly.
Older loans have a cushion that newer ones lack. Years of repayments and price growth mean owners from earlier cycles often sit on healthy equity and lower balances. A borrower from the last few years may have none of that. That gap is why arrears rise in one group while the national figure still looks manageable.
Refinancing: the escape hatch is narrowing for some
Refinancing is the usual way out of a high rate. It works only if a new lender will say yes.
A borrower who is already behind, or who has little equity, can fail the serviceability test on a new loan. They are often stuck with their current lender, which may be charging a higher rate than the best on offer. This is sometimes called a mortgage prisoner problem.
If you are in one of the exposed groups, the practical steps are:
- Check your LVR using a recent valuation, not the purchase price.
- Ask your current lender for its best retention rate before you apply elsewhere.
- If you are struggling, call early. Lenders have hardship arrangements, and they work better before missed payments pile up.
The catch
A temporary hardship arrangement can reduce pressure now, but it is not free. Interest can keep accruing and repayments can step back up later. Read the terms.
How lender risk appetite shifts
Lenders do not treat all arrears equally. When a cohort starts to show stress, credit policy tends to tighten at the margin. Expect tougher assessment of high-LVR applications, closer scrutiny of investor loans and more caution with some regional postcodes.
The second-order effect matters. Tighter lending for those groups can reduce buyer demand in the same areas, which can soften prices there. Softer prices push LVRs higher for existing owners, which can raise arrears risk further. It is a feedback loop, and it tends to play out slowly rather than suddenly.
What the data cannot tell you yet
A few things are unknown. Arrears figures lag, so today’s data reflects stress from several months ago. Most borrowers in arrears also cure their position, and many never reach a forced sale. A rise in arrears is a warning, not a forecast of widespread losses.
Borrowers are also not a single type. Employment is the biggest swing factor. If the job market holds up, most households can absorb the pressure. If unemployment rises materially, the picture changes quickly, and the cohorts above would be hit first.
