APRA's New DTI Cap: What It Means for Australian Expat Borrowers in 2026

TL;DR: From 1 February 2026, APRA capped how many high debt-to-income loans Australian lenders can write. For expats, this stacks on top of the existing foreign income shading problem — meaning your borrowing capacity may be lower than you expect. This article explains how the cap works, why expats are disproportionately affected, and what to do about it.

A new rule that most brokers haven't explained properly

Since February 2026, the Australian Prudential Regulation Authority has been actively limiting high debt-to-income lending. Specifically, lenders can't have more than 20% of their new home loan approvals exceed a 6x income DTI ratio.

On its own, this affects plenty of buyers. But for Aussie expats, it compounds a problem that already exists: foreign income shading.

Here's the sequence. You earn in Singapore dollars or Hong Kong dollars or AED. Your Australian lender takes that income and discounts it — typically 10–20% — to account for currency risk. They then convert the remainder to Australian dollars at current exchange rates. The 6x DTI cap is applied to that already-reduced figure.

So if you earn SGD 200,000 a year and the lender shades it to SGD 160,000 before converting, you're working with a smaller income base before the cap even kicks in. The ceiling is lower than your actual earnings would suggest.

A concrete example

Let's say you're earning SGD 200,000 base salary in Singapore. A common lender assessment looks something like this:

• SGD 200,000 income shaded to SGD 160,000 (20% discount)
• Converted to AUD at ~1.10: approximately AUD 145,000
• 6x DTI cap applied: maximum loan of AUD 870,000

Before the DTI cap, that same income and lender policy might have supported a loan of AUD 1.0–1.1M depending on living expenses. The cap has taken around AUD 200,000–230,000 off the ceiling.

For someone targeting a $1M property with a 20% deposit, that gap matters a lot.

Not every lender applies it the same way

The DTI cap is a macro-prudential tool, not a hard statutory rule applied identically everywhere. APRA sets the system-level limit, but each lender manages their own allocation. Some lenders have used more of their high-DTI headroom than others. Some have tightened their internal policies ahead of the formal cap. Others are still approving loans above 6x where they have room.

The practical upshot: lender choice matters more than ever. Submitting to the wrong lender — one that's already hit its DTI ceiling for the month — doesn't just slow things down. It may result in a declined application that leaves a mark on your credit file.

This is where lender policy knowledge becomes genuinely valuable, rather than just a differentiator people claim to have. If your broker doesn't know which lenders currently have capacity in their high-DTI allocation, they can't tell you where to submit.

What components of income can help?

The DTI calculation uses assessed income. So the more of your income that gets properly included — and at the right shading rate — the better your position.

Most expats have income components beyond base salary: bonuses, RSUs, housing allowances, company car allowances, school fee allowances. Australian lenders vary significantly in how they treat each of these. Some will include 100% of regular bonuses. Some will include 50%. Some will exclude allowances altogether.

Getting the income pack right — which components to include, how to evidence them, which lenders will count them — is where a specialised broker adds real money to the outcome. Not because they know a secret, but because they've done enough expat submissions to know what each lender's credit team will and won't accept.

It's also worth checking your borrowing capacity with current income figures before you go any further. The AEXPHL calculator gives you a starting point — and flags where the foreign income piece affects the output.

What about refinancing?

The cap applies to refinances as well. If you're an existing borrower looking to move to a better rate, the new lender will apply the DTI test to your current loan amount against your assessed income.

For some expats, this means a like-for-like refinance (same loan amount, different lender) will still go through — the loan isn't increasing so the DTI isn't worsening. Others, particularly those who took out large loans relative to income during lower-rate periods, may find that refinancing to a better product requires staying with their current lender and negotiating rate there instead.

Neither outcome is necessarily bad. But knowing which situation you're in before you start the process saves time and avoids unnecessary credit enquiries.

What to do now

If you're planning to buy Australian property in 2026, a few practical steps:

1. Get a current capacity assessment — using your actual income including all components, with current lender shading policies and the DTI cap applied. Don't rely on a capacity figure you got 12 months ago.
2. Reduce other debts — credit cards, personal loans, and car loans all reduce your assessed serviceability. Paying down or cancelling unused credit limits before applying can move the numbers meaningfully.
3. Choose the right lender — not all lenders assess your income type the same way, and not all have the same DTI headroom right now. This is not a "submit to your bank and see" moment.
4. Have your income documentation tight — payslips, employment contracts, bonus history, proof of allowances. Lenders under DTI pressure scrutinise applications more carefully, not less.

If you want to talk through where the DTI cap specifically affects your situation — whether that's borrowing for a new purchase, refinancing, or just understanding what you can realistically target — book a call and we'll run through it. No forms, just a conversation.

Frequently Asked Questions

What is APRA's DTI cap and when did it start?

APRA's debt-to-income cap limits how many high-DTI loans banks can write. From 1 February 2026, no more than 20% of a lender's new home loan book can exceed a 6x income DTI ratio. This applies across all borrowers, but hits expats harder because their foreign income is already discounted before the cap is applied.

How does the DTI cap affect expats specifically?

Expat income is shaded (discounted) 10–20% by most Australian lenders before it's assessed for serviceability. So an expat earning SGD 200,000 might have their income assessed at AUD 130,000–140,000 after shading and conversion. The 6x DTI cap is then applied to that lower figure — meaning the maximum loan size is capped lower than the expat's actual earnings would suggest.

Can I still borrow above 6x my income as an expat?

In most cases, no. With APRA's cap in place, lenders are limiting new loans above 6x the assessed income. Some lenders have headroom within the 20% high-DTI allocation, but this varies by lender and changes monthly. A specialist broker can tell you which lenders currently have capacity in that allocation.

Does the DTI cap apply to refinancing as well?

Yes, it applies to both new purchases and refinances. If your existing loan-to-income ratio already exceeds 6x under the lender's assessment methodology, refinancing to a new lender may be difficult. Some lenders have more flexibility for like-for-like refinances where the loan amount isn't increasing.

What can expats do to maximise borrowing capacity under the new rules?

The main levers are: choosing a lender with a more favourable income shading policy, correctly including all income components (base salary, bonuses, RSUs, allowances) in the assessment, reducing other debts before applying, and timing the application when the target lender has headroom in its DTI allocation. A broker who understands both foreign income policy and the DTI cap mechanics is essential.
