A broker-backed non-bank lender just raised $1.2 billion through a residential mortgage-backed securities transaction, matching the same lender’s record from February and settling on 29 September. That’s the 21st deal from this program since it started, taking total issuance to $13.1 billion.
The detail that matters: investor demand came from both domestic and offshore buyers, the deal priced across nine tranches with the two largest senior notes carrying triple-A ratings, and more than half the lender’s outstanding funding now comes from long-term securitisation rather than short-term warehouse lines.
That last point is the shift. When a non-bank moves from rolling short-term funding to locking in multi-year capital through RMBS, it gains the runway to compete on price without watching the warehouse limit every week. For borrowers, that means another lender with capacity to write new loans and chase refinancing volume when the major banks pull back.
Why securitisation appetite stayed strong
Investors keep buying Australian RMBS because the underlying loans are performing. Arrears across non-bank portfolios have ticked up from 2023 lows but remain well below long-run averages, and loss rates are still minimal.
The other driver: yield. The largest tranche in this deal priced at 103 basis points over the bank bill swap rate with a weighted average life of 2.9 years. That margin sits in the middle of the range seen across the past 18 months, not cheap, not expensive, just steady. For a global bond investor hunting yield in a market where central bank cuts are still months away, triple-A Australian residential paper at 100-plus basis points looks functional.
In plain English
- RMBS is a way for non-bank lenders to turn their loan book into bonds that investors buy, giving the lender cash to write more mortgages
- The triple-A rating on the senior tranches means ratings agencies view default risk as extremely low, based on loan-to-value ratios, borrower income buffers and historical performance
- BBSW is the benchmark rate banks charge each other for short-term loans, the margin over BBSW is the extra return investors demand for credit risk
What happens when funding stays open
Non-banks now write roughly one in nine Australian home loans. When their funding lines stay open and priced at levels that allow a margin, they keep competing for volume. That shows up as lower advertised rates on refinancing offers, faster turnaround on pre-approvals, and willingness to take on borrowers the major banks decline because of complex income or minor credit events.
The pressure flows backward: if a non-bank is offering a three-year fixed rate 15 basis points cheaper than a major bank, the major bank either matches or accepts it will lose that customer. Rate competition doesn’t require every lender to cut, it just requires enough lenders with capacity to make the others respond.
Over the past 12 months, refinancing rates have dropped below 6 per cent as lenders chased market share in a slower origination environment. Non-bank securitisation appetite is part of the reason that price war didn’t fizzle out when new lending volumes fell.
The part most people miss
Securitisation appetite is a trailing indicator, not a leading one. Investors are buying bonds backed by loans already written and performing well. If arrears spike or property prices fall sharply enough to push loan-to-value ratios above comfort levels, the next deal either prices wider or doesn’t get done.
That hasn’t happened yet, but the scenario is straightforward: unemployment rises above 4.5 per cent, mortgage stress moves from the edges into the middle of the borrower distribution, and arrears jump. At that point, the RMBS market reprices or pulls back, non-banks lose funding capacity, and rate competition evaporates.
The timeline for that scenario depends on how long the RBA holds rates at current levels and whether wage growth keeps serviceability buffers intact. Base case is another six to nine months of steady but slower property market activity, with funding markets open but not loose. Downside case is a sharper downturn triggered by an external shock or faster-than-expected job losses, and the funding window narrows quickly.
What changes the picture
Three things would tighten non-bank funding conditions before arrears force the issue:
- A major offshore credit event that spooks bond investors globally and makes them pull back from all non-domestic assets, including Australian RMBS
- A ratings downgrade on a large non-bank portfolio due to underwriting quality concerns, which would reprice the entire sector wider
- Regulatory intervention that changes capital treatment or disclosure requirements for RMBS investors, reducing demand
None of those are imminent, but the first one is the wildcard, it’s outside Australian control and can happen fast.
If you’re refinancing or buying
The practical take: non-bank lenders still have funding capacity and are competing for volume. If you’re refinancing, get quotes from at least one non-bank alongside the major banks, the gap can be 20 to 40 basis points, which is $80 to $160 a month on a $500,000 loan.
If you’re buying and a major bank knocked you back because of borderline serviceability or a past default, a non-bank may still write the deal. The trade-off is usually a slightly higher rate and less flexibility on features like offset accounts or unlimited redraws, but the difference between getting a loan and not getting one is binary.
One red flag: if a non-bank is offering a rate materially below the rest of the market with no obvious trade-off, ask what changes after the honeymoon period ends. Some deals load the real cost into year two or three.
