The RBA's October Financial Stability Review judged that non-bank lenders do not pose a system-wide threat, pointing to one deciding factor: their relatively small size.

Not every loan in Australia comes from a bank. Lenders operating outside the banking system also provide credit to households and businesses, and the Reserve Bank of Australia (RBA) keeps a close eye on them as part of its regular check on financial stability.

In its October 2026 Financial Stability Review (FSR), released on 1 October, the RBA's verdict on this part of the market was brief and specific: "system-wide risks to stability posed by non-bank lenders remain contained by their relatively small size".

That single sentence does a lot of work. It acknowledges that risks exist, limits the concern to the system-wide level, and names the reason the RBA is not more worried. This article looks at each of those elements and at the wider backdrop against which the judgement was made.

Unpacking a carefully worded sentence

Central bank language is usually chosen with care, and this finding is a good example. Three phrases stand out.

  • "system-wide risks": the RBA is assessing whether non-bank lenders could threaten the stability of the financial system as a whole. That is a different question from whether any individual lender, or any individual borrower, could run into difficulty.
  • "remain contained": the word "remain" signals that this describes an ongoing state of affairs rather than a new development. The word "contained" implies the risks are present but limited in their reach.
  • "by their relatively small size": the RBA identifies size as the reason the risks do not spread to the wider system.

The structure of the sentence also implies a condition. If size is what keeps the risks contained, then the size of the non-bank sector relative to the rest of the system is a natural thing to keep watching.

Why size is the deciding factor

In general terms, a lender's problems become a stability issue when they are large enough to affect a big share of borrowers, markets or other institutions at once. A small lender that runs into trouble can cause real hardship for its own customers without disrupting the flow of credit across the economy.

That distinction sits at the heart of how financial stability reviews work. They are less concerned with whether every institution is sound in every circumstance, and more concerned with whether problems in one part of the system could cascade into others.

By pointing to size, the RBA is saying that even if non-bank lenders came under strain, the scale of their lending is not large enough, relative to the system, to pose a system-wide threat on current settings.

The contrast with the banks is instructive. The Review found that "Australian banks are well positioned to continue lending, even in a downturn". Given that the RBA describes non-bank lenders as relatively small, the resilience of the banks carries far more weight for overall stability. For non-banks, the RBA's reassurance rests on a different basis: not that they are immune to stress, but that their footprint is small.

The same lens, applied overseas

The RBA's global chapter shows why it pays close attention to lending and leverage outside traditional banks. Several of the vulnerabilities it flagged sit in non-bank parts of the international financial system.

  • Private credit funds have used redemption limits, known as "gates", which the RBA said "have so far helped to contain liquidity pressures and the need for forced asset sales".
  • "Hedge fund leverage is near record highs, with total repo borrowing by US hedge funds over US$3 trillion" – around 10 per cent of US GDP, according to the Review.
  • "Risk premia in global equity and credit markets remain low by historical standards".

These are not Australian non-bank lenders, and the RBA did not draw a direct link between them. But they illustrate why the scale of activity outside banks matters. Overseas, some of these sectors feature prominently in the RBA's assessment of global risks. At home, the RBA's judgement is that non-bank lenders remain small enough for their risks to be contained. Those are two different questions, but they rest on the same principle: scale and leverage determine whether trouble in one corner of finance can spread.

Overall, the RBA concluded that "Australia's financial system has a good degree of resilience, but global and operational vulnerabilities continue to mount", citing "elevated threats from ongoing geopolitical tensions, growing vulnerabilities in global financial markets", as well as "advances in artificial intelligence and critical service provider disruptions".

The domestic backdrop

The RBA's view of non-bank lenders sits within a broadly steady picture of Australian borrowers. On households, it found that "Most Australian households with mortgages remain well placed to manage more difficult conditions". The share of variable-rate owner-occupier borrowers in cash-flow shortfall "remains relatively low at around 2 per cent", and 90-day-plus arrears remain around pre-pandemic levels despite edging up over the year to date.

Housing credit growth has eased recently, particularly for investors. On businesses, the Review said "Most businesses should be able to manage elevated cost pressures, although conditions are more challenging in some sectors", with stress still elevated in hospitality, construction and transport. Non-performing commercial real estate loans remain low. Assistant Governor (Economic) Sarah Hunter said on 22 September that she saw no signs of systemic financial distress, though individuals can struggle if their income changes.

All of this is unfolding as interest rates rise. The RBA's Monetary Policy Board lifted the cash rate target by 25 basis points to 4.60 per cent on 29 September, its fourth increase in 2026. Governor Michele Bullock acknowledged that day: "I know this decision is difficult for households with a mortgage and businesses with loans."

The bottom line

The October FSR concluded that "system-wide risks to stability posed by non-bank lenders remain contained by their relatively small size". The judgement does not say non-bank lenders are risk-free; it says their scale is too small to threaten the system as a whole.

What to watch: the relative size of non-bank lending in future Reviews, developments in global private credit and hedge fund leverage, and the RBA's next policy decision at 2.30 pm AEDT on 3 November.
