Australian investors who held only public fixed income over the last decade earned a coupon for taking duration risk they were never properly compensated for. Investors who allocated to Australian business lending through well-structured private credit vehicles earned a materially higher running yield, with lower drawdowns and almost no exposure to interest-rate beta. The difference is not a matter of taste. It is a matter of structure.
Between 2015 and 2025, Australian fixed-income investors lived through one of the most difficult environments the asset class has experienced since the early 1990s. The cash rate fell from 2.50% to a record low of 0.10%, then climbed to 4.35% inside eighteen months as the Reserve Bank confronted post-pandemic inflation. The AusBond Composite, the most widely held benchmark for Australian core fixed income, delivered its worst calendar year on record in 2022 — a drawdown of over 9% that was driven almost entirely by duration, not credit.
For investors and their advisers, the lesson was uncomfortable. The defensive sleeve in a balanced portfolio was supposed to serve as ballast. Instead, it was the source of loss in the same year that growth assets sold off. Correlation moved exactly the wrong way at exactly the wrong moment, and the conventional 60/40 model was tested in a way clients had never experienced. The implicit assumption that bonds would always cushion equity drawdowns was revealed for what it had always been: an assumption built on the experience of a particular regime, not a permanent feature of the asset class.
Behind the headline drawdown sits a structural issue that is easy to overlook in steady markets. The Australian public fixed income universe is dominated by long-duration government and semi-government paper, with credit spreads on investment-grade corporate debt that are persistently tight relative to the risk of multi-year capital losses if rates move against you. Yield, in other words, has been the smaller share of the total return equation. Price has been the larger one — and it has worked in both directions.
Even after the painful repricing of 2022 and the partial recovery in the years since, an investor sitting in a conventional Australian fixed income index today is being asked to take roughly six years of duration risk to earn a yield that, after fees, is barely a percentage point above the cash rate. That is a poor trade for an asset that is supposed to be defensive. It is an even poorer trade when investors can access floating-rate alternatives that pay a meaningfully higher running yield without the same exposure to the inflation path.
While the public bond market wrestled with duration, Australian private credit grew from a niche allocation into a mainstream asset class. The market expanded from roughly $80 billion in 2015 to a figure now comfortably above $200 billion1, depending on how you count the various sleeves — corporate direct lending, real estate debt, consumer and SME warehouse facilities, and specialty finance. That growth has been driven not by speculative enthusiasm but by a structural withdrawal of bank capital from segments of the economy that still need funding. The borrowers were always there. The question was who would lend to them on appropriate terms.
The performance experience for investors who chose carefully was different in three important ways. Returns were higher on a running-yield basis, typically delivered net to investors at a margin of 2.5% to 5% over the bank bill swap rate . Volatility was lower, because the assets being held are floating-rate loans with contractual cashflows, not bonds priced daily against a moving discount curve. And drawdowns were largely a function of credit losses rather than rate moves — meaning that disciplined origination and structuring did most of the work to keep returns intact.2
The contrast with public fixed income is sharpest precisely when investors most need their defensive sleeve to perform. In 2020, when COVID dislocated markets and high-yield indices saw double-digit drawdowns, well-structured Australian business lending pools held their value. In 2022, when government bonds delivered their worst result in a generation, those same pools continued to pay coupons close to their stated targets. The asset class did not promise to be uncorrelated with everything — it promised to behave differently from public bonds when rates moved. It delivered on that promise.
"The defensive sleeve of a balanced portfolio is supposed to be the ballast. In 2022, for many Australian investors, it was the source of loss."
It is tempting to look at the last decade and conclude that private credit simply benefited from a benign credit environment. That reading misses the architecture of how returns are built in the two asset classes.
Public fixed income is, at its core, an instrument for taking interest-rate risk. The yield to maturity on a ten-year Commonwealth Government bond is the price of locking in that rate against a future inflation path. When inflation surprises, the price moves. The investor is not paid a premium for credit selection or origination skill — they are paid for accepting duration.
Private credit, particularly in the form of Australian business lending delivered through securitised warehouse structures, is the opposite. The investor is paid for accepting credit risk on a diversified pool of contractual cash flows, with the rate they receive resetting each month against the bank bill rate. There is no duration to speak of. The yield is the yield. If the loans perform, the return is largely what was advertised on day one — and if loans default, the structural protections built into the warehouse decide how much, if any, of that loss reaches the investor.
These are two different jobs. They are priced in two different ways. Comparing them on returns alone misses the point. The right comparison is on the economic risk being taken — and on that basis, well-structured Australian business lending has compensated investors more fairly than public fixed income has across the last decade.
Within the broader private credit universe, Australian business lending sits in a particularly attractive corner. The borrowers are operating businesses — established SMEs, asset-backed lenders, equipment financiers, and specialty finance platforms — that need working capital to grow. The loans are typically short-duration, secured against contractual receivables or hard collateral, and originated by experienced platforms with deep underwriting capability.
The Australian banking sector has been pulling back from this segment for over a decade, driven by Basel 3 capital rules, APRA's tightened lending standards, and the post-Royal Commission reset of risk appetite. The major banks have concentrated their balance sheets on residential mortgages and large corporate relationships, leaving a structural funding gap in the SME and specialty finance space. That gap is now being filled by non-bank lenders — and the most capital-efficient way to fund those non-bank lenders is through securitised warehouse facilities.
For investors, this is where the opportunity becomes interesting. Investing in a warehouse structure is not the same as investing in a single loan. It is investing in a diversified pool of loans, with senior funders ahead of you absorbing first-loss risk, with regular cash flow distributions, and with mark-to-market protection that public bondholders do not enjoy. When done well, this is, in our view, one of the most compelling risk-adjusted return profiles available to Australian investors today.
It is worth pausing on what a securitised warehouse actually does for the investor, because it is the structural feature that distinguishes thoughtful Australian private credit from less disciplined alternatives. A warehouse is a special purpose vehicle that holds a defined pool of receivables. It is funded by a senior bank facility — typically from a major Australian bank (Once the lender reaches a certain stage of maturity. If they are smaller and have less track record, private credit funds will fill this senior piece) — that sits ahead of the equity and mezzanine investors. The senior facility provides leverage and discipline because the bank performs its own credit review of every asset that enters the pool. The mezzanine and equity investors enjoy enhanced yield, but they also benefit from the bank's first-loss protection and from the eligibility criteria the bank enforces. The result is an asset that, properly executed, delivers attractive returns inside a structure that institutional senior lenders have already underwritten.
A useful exercise for any adviser is to lay the cashflow profile of a generic Australian government bond next to that of a securitised business lending facility. The bond pays a fixed semi-annual coupon, and returns face value at maturity. Its present value is recalculated continuously as the discount curve shifts, introducing mark-to-market noise unrelated to the borrower's ability to repay. The business lending pool, by contrast, pays a monthly distribution that resets against the bank bill rate, with principal returning gradually as underlying loans amortise. There is no terminal repricing event because there is no fixed-rate principal to discount. The investor receives a stream of cash that closely tracks what the underlying borrowers actually pay.
From an asset-liability matching perspective, the second profile is often the more useful one. Many Australian retirees and pre-retirees do not need a lump-sum return of capital at a particular date. They need a reliable monthly income stream that keeps pace with short rates. That is exactly what well-structured business lending provides. The fact that it does so with credit enhancement and senior bank discipline embedded in the structure is the second-order benefit that pushes it ahead of competing income alternatives.
We resist the temptation to draw simple conclusions from a single decade of data. The next ten years will not look like the last ten. But the structural arguments hold across regimes. A floating-rate asset paid a credit margin will outperform a fixed-rate asset paid a duration premium whenever credit losses are well managed, and rates are anywhere other than falling sharply. That has been the case for most of the last decade, and we believe it will be the case for most of the decade ahead.
What the last decade also tells us is that allocation matters more than ever. Investors who treated private credit as a single, undifferentiated bucket — and who chose managers without scrutinising structure, origination quality, or alignment of interests — discovered that not all private credit is the same. The dispersion of outcomes across managers has been wider than in almost any other asset class. We will take that point up in detail in our companion paper, Private Credit — A Broad Church.
For the financial adviser building a defensive sleeve in 2026, the conventional answer of "add duration" deserves to be challenged. Duration is one tool. It is not the only tool. A meaningful allocation to high-quality Australian business lending — accessed through funds with robust securitised structures, transparent underwriting, and conservative leverage — can deliver the income that bonds were supposed to deliver, with markedly less interest-rate sensitivity and a different correlation profile to risk assets.
We are not arguing for the abandonment of public fixed income. Government bonds still play a role in extreme stress, and liquid investment-grade credit still has a place in many portfolios. We are arguing that the defensive sleeve of an Australian portfolio in 2026 should look different from the defensive sleeve of 2015 — because the world it operates in has changed, and the menu of available risk premia has changed with it.
"A floating-rate asset paid a credit margin outperforms a fixed-rate asset paid a duration premium across most regimes. That is not an opinion. It is arithmetic."
At Aura Private Credit, we have built our platform around exactly that view. We invest in Australian business lending through securitised warehouse structures because we believe in a disciplined and capital-efficient way to access this opportunity. The combination of short-duration, floating-rate exposure, structural credit protection, and diversified borrower pools is, in our view, the closest thing to a structural improvement on the traditional defensive sleeve that the Australian market currently offers.
The decade ahead will not be easy. Inflation, interest rate uncertainty, and economic cycles are part of the territory. But the architecture of well-built Australian private credit is designed to carry investors through those cycles with their capital intact and their income flowing. That is, ultimately, what investors want from their defensive allocation. The last decade has shown that the public fixed-income market has not always delivered. The opportunity is to allocate toward what does.
When evaluating a private credit allocation against an existing fixed income sleeve, we believe five questions cut through the noise. First, what is the duration of the underlying assets, and how does that compare to your client's actual liability profile? Second, what is the floating-rate share of the income stream, and how will that income behave if the cash rate moves another two percentage points in either direction? Third, who originates the underlying loans, what is their multi-cycle track record, and how do they get paid? Fourth, what structural protections sit between your client's capital and the first dollar of credit loss — and who has underwritten those protections? Fifth, what is the manager's policy on leverage, valuation, and liquidity, and how does that policy hold up under genuine stress rather than the stress that has actually been observed?
These questions do not have a single right answer. Different managers will give different answers that reflect different strategies, and many of those strategies will be reasonable. But the act of asking the questions — and being satisfied with the answers — is what separates a thoughtful private credit allocation from one that is driven by yield-chasing alone. We believe Australian business lending through securitised structures, when delivered by an experienced manager, gives advisers comfortable answers to all five questions.
The conclusion is not that private credit replaces public fixed income. The conclusion is that the share of an Australian portfolio's defensive sleeve that should be held in floating-rate, well-secured, structurally protected business lending is meaningfully larger today than it was a decade ago — and meaningfully larger than most balanced portfolios currently hold. Closing that gap is, in our view, one of the more meaningful portfolio adjustments available in 2026.
