Key Highlights

• About 2% of variable-rate owner-occupier borrowers were in cash-flow shortfall, according to the Financial Stability Review.

• That share rose a little over the first half of 2026 but remains relatively low.

• The Review said the financial system remains resilient, but there is no room for complacency.

• The next Financial Stability Review is scheduled for 25 March 2027.

One statistic in the Reserve Bank's October Financial Stability Review – the share of variable-rate owner-occupiers spending more than they earn – does much of the work behind the central bank's measured tone on household stress.

When interest rates rise, the question many people ask is simple: how many borrowers are actually in trouble? The Reserve Bank of Australia (RBA) tries to answer that with a specific measure, and in its Financial Stability Review (FSR) of October 2026 the answer was "around 2 per cent". That figure, roughly two borrowers in every hundred, sits behind the RBA's view that household finances are under pressure but not, in aggregate, breaking.

What a "cash-flow shortfall" means

The measure focuses on variable-rate owner-occupier borrowers – people with a Mortgage on the home they live in, whose repayments move with interest rates. Broadly, a borrower in cash-flow shortfall is one whose regular income is not enough to keep up with their mortgage and essential costs, so the gap has to be met some other way, such as from savings.

According to the FSR, the share of these borrowers in shortfall "increased a little over the first half of 2026, but remains relatively low at around 2 per cent."

That sentence contains two messages. The direction is up: more households slipped into shortfall during the first half of the year. The level, though, remains small relative to the whole population of variable-rate owner-occupiers.

Buffers and Equity do the heavy lifting

A shortfall does not automatically mean missed payments. Many borrowers hold savings that can carry them through a period when income falls short. The FSR addresses this directly, estimating that the median borrower can cover "over a year of scheduled mortgage payments at current interest rates" from those buffers.

The word "median" is important. It describes the borrower in the middle of the distribution, which means half hold less than that and half hold more. Some households in shortfall will have deep buffers and be able to absorb the gap for a long time; others will have little to fall back on. The aggregate number cannot show which group a particular household belongs to.

Still, the combination of a low shortfall rate and sizeable median buffers explains why the RBA judged: "Most borrowers appear well placed to manage ongoing cost pressures amid declining housing prices."

A second line of defence is equity in the home. A borrower who gets into difficulty but owes less than the property is worth generally has more Options than one who owes more. The FSR estimates that "less than 1 per cent of borrowers" are in Negative equity – the situation in which the Loan exceeds the value of the home.

This is relevant because housing prices have been falling. The November Statement on Monetary Policy says "housing prices have declined by more than expected", and that "Housing prices have declined further from their peak in March". Falling prices erode equity, so the negative equity share is a figure to watch. As at the October FSR, however, it remained very small.

Why the timing matters

The October FSR was published on 1 October 2026, and its shortfall estimate relates to the first half of the year. That means it predates the Board's decision on 3 November to raise the cash rate target by 25 basis points to 4.85 per cent, from 4.60 per cent.

A higher cash rate, if passed on by lenders, raises scheduled repayments on variable-rate loans and would be expected to push some additional borrowers towards shortfall. The FSR's own phrasing – buffers covering payments "at current interest rates" – is a reminder that the estimate is tied to the rates prevailing when the analysis was done.

To give a sense of scale, consider an illustration using hypothetical rates rather than any RBA or lender figure. On a 30-year principal-and-interest loan of $550,000, a rise in an assumed rate from 6.10 per cent to 6.35 per cent would lift repayments from about $3,333 to about $3,422 a month – roughly $89 more. Actual lender rates and how much of any cash rate change they pass on vary, so this is an illustration only.

The next FSR, due on 25 March 2027, will be the first to capture the effect of the November decision on this measure.

Calm, but not complacent

The RBA's overall assessment in October was: "Our latest assessment is that the Australian financial system remains resilient, but there's no room for complacency." It added that "The principal risks are increasingly coming from abroad", and it flagged operational and cyber risk as areas of concern.

That framing helps explain the shortfall figure's role. The RBA is not saying household stress is absent; it is saying the domestic household sector, taken as a whole, does not currently look like the main threat to the financial system. The Board's monetary policy decisions are made on a different basis – the goal of returning Inflation to target – and Governor Michele Bullock acknowledged the cost of that approach when she said: "Some pain now will prevent even worse pain down the track."

The labour market is the other variable that could change the picture. Shortfalls often begin with a fall in income rather than a rise in repayments. The November SMP reports that "The Unemployment rate rose by more than expected to average 4.6 per cent in the September quarter", and forecasts it to reach 5.1 per cent by December 2028. A softer jobs market is one channel through which the 2 per cent figure could drift higher.

The bottom line

"Around 2 per cent" is a small number with a large job. It underpins the RBA's judgement that most variable-rate owner-occupiers can absorb current cost pressures, supported by median buffers worth more than a year of repayments and very low negative equity. But the figure was rising in the first half of 2026, it predates the November rate rise, and it depends on employment holding up. It is a measure of resilience at a point in time, not a guarantee about the months ahead.
