The Quiet Migration: Why Prime Borrowers Are Flowing to Non-Banks — And What It Means for Your Panel

Two and a half months into APRA’s debt-to-income cap, the shift everyone predicted is happening — just faster and more broadly than most brokers expected. Non-bank lenders are no longer the fallback for impaired credit. They’re becoming the go-to for prime borrowers with solid incomes and clean histories who simply own too much property for the major banks to touch.

If your lender panel still treats non-banks as a last resort, you’re not just behind the curve — you’re losing deals to brokers who moved months ago.

What Changed on 1 February

APRA’s DTI limit, activated on 1 February 2026, caps authorised deposit-taking institutions (ADIs) at issuing no more than 20 per cent of new residential mortgage lending at a debt-to-income ratio of six or above. The cap applies separately to owner-occupier and investor portfolios.

The rationale is sound — containing systemic risk at a time when two consecutive RBA hikes have pushed the cash rate to 4.10 per cent, investment lending jumped 31.8 per cent over 2025, and investors now account for 39.7 per cent of all new lending by value. APRA wants to prevent a concentration of high-leverage borrowers inside the banking system.

But here’s the detail that matters most for brokers: the cap applies only to ADIs. Non-bank lenders, private lenders, and specialist credit providers are not subject to it.

The Numbers Tell the Story

Non-ADI mortgage volumes surged 25.3 per cent in 2025, compared to just 3.9 per cent growth across the major banks, according to The Adviser. That gap was already widening before the DTI cap kicked in. Now, with the cap firmly in place and banks actively managing their high-DTI allocation, the acceleration is real.

The RBA’s February 2026 Bulletin noted that the broker-originated share of mortgages has risen from around 50 per cent in 2019 to approximately 65 per cent in 2025. Combined with the structural deepening of Australia’s securitisation market — which has lowered non-bank funding costs — the conditions are set for non-banks to capture an even larger share of broker-originated loans this year.

Meanwhile, private credit assets under management in Australia have reached approximately $224 billion, with APRA itself acknowledging it will “closely monitor any spillover effects, including shifts of lending activity toward non-ADI lenders.”

Who’s Actually Being Turned Away?

This is the part that should concern every broker running a client book heavy on investors or self-employed borrowers. The DTI cap doesn’t just catch stretched applicants — it catches successful ones.

A dual-income household earning $250,000 with an existing $1.2 million mortgage and a $300,000 investment loan already sits at a DTI of six. Add another $200,000 top-up for a renovation or a new investment purchase and they’re well past the threshold. Credit score: excellent. Serviceability: fine. Bank answer under the DTI cap: declined — not because they can’t afford it, but because the bank has hit its 20 per cent allocation.

As Pepper Money CEO Mario Rehayem put it in his January outlook: “Every week, brokers present us with significant examples where creditworthy borrowers are turned down by banks’ strict tick-box criteria.” With the DTI cap now live, those examples are multiplying.

How Non-Banks Are Filling the Gap

Non-bank lenders assess these borrowers differently. Without the DTI cap constraint, they evaluate the full picture — income, equity, asset quality, loan-to-value ratios, and exit strategy. A high DTI ratio alone doesn’t trigger an automatic decline.

Approval timelines are another differentiator. Several non-bank lenders are issuing indicative terms within 24 to 48 hours, with some completing settlement within two to three weeks — a meaningful advantage when bank turnaround times remain stretched.

The pricing gap is narrowing too. While non-bank rates still sit above major bank offerings — first mortgage products typically start around the mid-6 per cent range for prime borrowers, with specialist products higher — the spread has compressed as securitisation markets have deepened and non-bank funding costs have fallen. For borrowers who can’t get a bank approval at all, the rate premium is academic.

Customer acceptance has also shifted dramatically. Around 85 per cent of mortgage customers expressed willingness to consider a non-bank lender in 2025. The old stigma of “if you’re with a non-bank, something must be wrong” is fading fast.

What This Means for Your Brokerage — Practically

The DTI cap creates a structural, ongoing flow of prime borrowers who will be declined by ADIs. This isn’t a one-off policy adjustment — it’s a permanent feature of the lending landscape. Brokers who build deep relationships with non-bank lenders now will capture this flow. Those who don’t will watch clients walk to competitors who can get the deal done.

Here’s what to review this week:

Audit your lender panel. How many non-bank lenders do you have active accreditations with? If the answer is fewer than three, you’re underweight. Look beyond the obvious names. Specialist lenders servicing investors, trust structures, and self-employed borrowers are where the DTI overflow is landing.

Re-segment your pipeline. Any client with existing property debt and a household DTI above 5.5 is a candidate for non-bank placement, even if they’d previously have gone straight to a major. Flag these in your CRM now rather than discovering the issue at pre-approval stage.

Update your client conversations. Many borrowers still assume “the bank” is the default. Proactively educating clients about the DTI cap — and positioning non-bank options as a legitimate, regulated alternative rather than a consolation prize — is a Best Interest Duty obligation as much as a business development opportunity. Under BID, you need to demonstrate that you’ve considered the borrower’s full range of options, not just the lender with the lowest rate.

Understand the pricing conversation. Non-bank rates are higher. But a slightly higher rate on an approved loan beats a perfect rate on a declined one. Help clients understand the total cost of delay — six months of waiting, rental costs, missed capital growth — against a 30 to 50 basis point rate premium.

Watch APRA’s next move. APRA has signalled it will monitor non-ADI spillover closely. If non-bank lending grows too fast or concentrates risk, further intervention is possible — potentially extending some form of DTI oversight to non-banks via ASIC or Treasury. Brokers should be prepared for the rules to evolve.

The Bigger Picture

The DTI cap is part of a broader shift in how credit is allocated in Australia. Banks are retreating from segments they once dominated — high-DTI lending, trust structures, complex self-employed income, small business finance. Non-banks are stepping in, backed by a maturing securitisation market and growing broker and borrower acceptance.

For brokers, this isn’t a threat — it’s an expansion of your value proposition. The borrowers being turned away by banks are often the most complex, highest-value clients. They need a broker who understands the non-bank landscape, can explain the trade-offs, and can place the loan efficiently. That’s the work banks can’t automate and borrowers can’t do themselves.

The non-bank shift isn’t coming. It’s here. The only question is whether your brokerage is set up to capture it.
