RBA Financial Stability Review October 2026: How Much Price Fall Can Australian Households Absorb?

Related tracker: the Cotality Home Value Index tracker carries the monthly price series this analysis draws on.

The Reserve Bank released its October 2026 Financial Stability Review on 1 October, the same morning Cotality reported a sixth straight monthly fall in national home values. Its verdict on borrowers was measured: “Most Australian households with mortgages remain well placed to manage more difficult conditions, even if housing prices were to fall sharply, although there are pockets of stress.”

Behind that sentence sit the numbers investors need: fewer than 1% of mortgage borrowers in negative equity, about 5% under a further uniform 20% fall, about 2% of variable-rate owner-occupiers in cash-flow shortfall, a median buffer of more than a year of repayments, and about 5% of mortgagors in shortfall under the Review's very adverse scenario, just above the 2023 peak.

In one sentence: on the RBA's evidence, the price fall so far and the one most forecasters expect are inside what household balance sheets can carry, so the floor for this cycle is more likely to be set by buyer demand and investor choice than by forced sales.

Our September Home Value Index analysis summarised the Review in one table; this piece works through the mechanics and where the reassurance stops.

What Does the October 2026 FSR Say About Households?

Real household disposable income per capita “declined slightly over the first half of 2026, but remains higher on average than in 2023 and 2024”; National Debt Helpline enquiries “increased modestly”, formal hardship “increased but remains low”, and severe financial stress is expected to “remain well below its 2024 peak”.

Set against the March Review, three things moved and one did not. The cash-flow shortfall share roughly doubled, from about 1% to about 2%. Arrears for lower-income, high-LVR and high loan-to-income borrowers stayed higher than for others “but have not picked up significantly since the start of the year”. Investor credit growth “has slowed recently and is expected to moderate further”. Negative equity did not move: still less than 1%.

The timing matters. The Review's figures predate the 29 September decision that took the cash rate to 4.60%, and its cash-flow projection rests on the August Statement outlook. The big four's variable rates rose 0.25 percentage points on 9 October, about $125 a month on a $600,000 interest-only loan. The 2% figure is the RBA's estimate on that August outlook, not a measurement of borrowers' position after the hike, and the Review does not say how much, or whether, the share moves from here.

How Much Can Prices Fall Before Negative Equity Spreads?

The dynamic LVR distribution

The RBA estimates negative equity from its Securitisation System, which tracks loan balances against updated values rather than purchase prices. Years of growth leave most loans far below 80% of current value, which is why the Review can report “less than 1 per cent of borrowers estimated to owe more on their loan than the value of their property” with Sydney already 8.6% below its February peak.

Graph 2.6 shows the modelled shift. “Even in a scenario involving a large uniform fall in housing prices of 20 per cent from current levels, only around 5 per cent of mortgages would fall into negative equity.” The March Review ran a harsher test, a 40% fall, and found “around 80 per cent of mortgagors are estimated to have positive equity”. Read together, the two Reviews sketch a ladder: roughly 1% now, 5% at a 20% fall, 20% at a 40% fall.

Who is exposed

The Review is specific about where the thin equity sits: “Recent buyers and those who took out higher LVR loans are more likely to be in negative equity. This includes first home buyers participating in the Australian Government 5% Deposit Scheme.” Risks from that group are “mitigated by the structure of the scheme”, and bank liaison suggests their hardship and arrears “remain contained”.

High-LVR lending has risen since the scheme's expansion in October 2025 “but remains low overall”; APRA's June-quarter data put loans funded at an LVR of 80% or more at 29.7% of new lending (APRA, released 17 September 2026).

Who Is Under Cash-Flow Stress Now, and Who Would Be in a Real Downturn?

The current reading

The Review estimates “around 2 per cent” of variable-rate owner-occupier borrowers are in cash-flow shortfall, a share that “increased a little over the first half of 2026, but remains relatively low”. Most of them “are estimated to have savings that would enable them to cover their cash flow shortfall for at least six months” (Graph 2.4). Across all borrowers, “the median borrower [is] able to cover over a year of scheduled mortgage payments at current interest rates from these buffers”, and “there has not been a meaningful increase in the share of borrowers who are persistently drawing down on these buffers” (Graph 2.5).

APRA's June-quarter statistics give the system-wide version: non-performing housing loans at 1.01% of credit, loans 30 to 89 days past due at 0.54%, offset balances of about $340 billion (13.3% of housing credit), and serviceability exceptions at 5.8% of new lending, up from 4.6% at the end of 2024, the one indicator moving the wrong way (APRA June 2026 highlights, 17 September; offsets and exceptions as reported by Mortgage Professional Australia, 29 September).

The very adverse scenario

The Review's Focus Topic 4.2 runs the household data through a scenario in which “current geopolitical tensions worsen and risks materialise, leading to further negative supply shocks”. Its inputs, in the Review's words: the “unemployment rate increases to 6.3 per cent, GDP falls by 1.4 per cent, housing prices fall by 20 per cent from current levels, inflation increases to 7 per cent and the cash rate increases to 5.6 per cent”.

The household outcome is contained. The share of mortgagors in cash-flow shortfall “increases to about 5 per cent”, which “just surpass[es] the peak observed in 2023”. About two-thirds of those borrowers “have sufficient savings buffers to cover at least six months of mortgage payments and essential expenses”. The group that combines a shortfall, low savings and negative equity, the borrowers who would actually default and crystallise a loss, is “less than 1 per cent”. Chapter 2.1 describes the same result as the share “at a higher risk of defaulting on their loans” rising to around 5%, “only a little higher than the peak in 2023”.

The scenario is a stress test, not a forecast. The scenario measure is run on Securitisation System mortgagors; the current 2% is the Review's variable-rate owner-occupier series, so the two columns are not on an identical base.

What Does the Review Say About Investors and Interest-Only Loans?

Investors: equity, arrears and behaviour

The Review's investor passage points two ways. “Like other borrowers, most investors have considerable equity positions in their properties and have historically exhibited lower rates of arrears and default than owner-occupiers.” Then: “In periods of declining housing prices, investors may be less willing to enter the market and more inclined to sell properties to limit losses. This can amplify price declines and contribute to a more pronounced downturn than would otherwise occur.”

A footnote runs the other way: grandfathered negative gearing (preserved for any residential property contracted before 7:30pm AEST on 12 May 2026) “could motivate some borrowers to hold on to their properties to maintain this ability”. The Review does not estimate which behaviour dominates.

On the demand side, investor credit growth “has slowed recently and is expected to moderate further in the period ahead in response to tax changes, tighter monetary policy settings and softer housing prices” (Graph 2.9); ABS Lending Indicators had investor commitments down 10.2% in the June quarter (ABS, 14 August 2026), and high-DTI loans were 8.9% of new investor lending, well inside APRA's 20% limit.

Interest-only: rising, and tolerated

“The share of new lending issued on interest-only terms has increased over the past year, though by itself this increase is not cause for concern.” APRA's June-quarter data put interest-only at 23.5% of new housing lending, up from 20.5% at the end of 2024. The Review's footnote explains the tolerance: interest-only terms let borrowers build larger liquidity buffers, at the cost of slower equity accumulation. That trade-off is the subject of our companion guide to interest-only versus principal-and-interest loans after the 4.60% hike.

Can the Banks Keep Lending Through a 20% Fall?

Chapter 3.1 reports a system Common Equity Tier 1 (CET1) ratio “well above regulatory requirements at 12.4 per cent in June 2026”. In “a very adverse economic downturn scenario that includes a 3 percentage point fall in GDP growth and a sharp 20 per cent collapse in housing prices” (its endnote adds unemployment at 6.3 per cent and a cash rate of 5.6 per cent; the household analysis in Focus Topic 4.2 frames the same scenario as a 1.4 per cent fall in the level of GDP), the ratio “is estimated to decline to around 11.6 per cent”, leaving “sufficient capital to continue lending to households and businesses”.

Loan quality supports that: “Over 90 per cent of housing NPLs … were considered well secured”, and banks “hold loss provisions of around 0.7 per cent of total credit outstanding”. Non-bank lenders “still only account for around 6 per cent of financial system assets”. The Review's one caution on lending sits in its Financial Stability Assessment: “It is important that lending standards remain sound in the face of continued strong competition in lending so that resilience is not eroded in an environment more prone to shocks.”

Where the Reassurance Stops: Four Gaps

1. The cut-off predates the hike. As above, the projection rests on the August Statement rate path and the cash rate has since risen to 4.60%. Westpac and ANZ expect 4.85% on 3 November and CBA and NAB expect a hold (bank calls as published 30 September to 6 October, compiled by Aussie; the primary notes are listed in our forecast review); markets priced about a 20% to 25% chance of a November rise between 30 September and 2 October. Each 0.25 points adds about $21 a month per $100,000 of interest-only debt. A higher rate path than August's would, other things equal, push the shortfall share above the projection, but the Review does not quantify that, and other things (income, rents, employment) are not equal.

2. The cash-flow measure is owner-occupier only. An investor's ability to hold depends on rent plus income less interest and costs. On our interest-cover table, a new 80% LVR investor loan in every capital except Darwin fails to cover even its interest from gross rent, and the Review's aggregate does not separate 2024 and 2025 buyers at 80% to 90% LVR from long-term holders.

3. A uniform fall is not this downturn. Sydney is 8.6% below its February peak and 97% of capital-city suburbs fell over the quarter. A uniform 20% fall understates the exposure of recent high-LVR buyers where values are falling fastest, and the Review does not publish negative equity by city.

4. A stress test is not a forecast, and behaviour is not in it. The scenario tests balance sheets under an assumed shock. The Review says its framework “does not routinely incorporate behavioural adjustments or feedback loops between the financial system and real economy”, so it models neither tighter lending standards nor the investor selling it says “can amplify price declines”. That loop runs through listings, days on market and clearance rates, not arrears. Sales are already 19.1% below a year ago and median days on market have gone from 23 to 39. If investor listings rise while buyers stay away, prices can fall further than household stress implies, with arrears low throughout.

What Does the October FSR Mean for Property Investors?

The Bottom Line

The October 2026 Financial Stability Review answers the question most investors are asking in October 2026, which is not how far prices will fall but whether the fall turns into forced selling. On the RBA's data, not at a system-wide scale under the conditions it modelled; individual defaults and mortgagee sales remain possible. Fewer than 1% of borrowers are under water after a 5.2% national fall, the median borrower is more than a year ahead on repayments, and a further 20% fall, beyond every published forecast, would put about 5% of mortgages into negative equity and about 5% of mortgagors into cash-flow shortfall. On the stress test, banks would keep lending through it.

What the Review does not do is measure investor cash flow, model investor selling or quantify the hike it was written before, and those are where an investor's own risk sits. Gross rent covers between about two-thirds and four-fifths of the interest on a new 80% LVR investor loan in every capital except Darwin, before holding costs, so holding is a decision about income, buffers and loan structure. The floor for this cycle is more likely to be set by buyers and by investors choosing to sell than by banks forcing them to, which makes listings, days on market, clearance rates and the 15 October unemployment figure more informative than arrears.
