Borrowers are adjusting to higher rates by trimming discretionary purchases rather than draining reserves, according to quarterly transaction-level data covering thousands of households. Average consumer spending dipped 0.2% in the three months to May 2026, the first quarterly fall in a year, while savings balances climbed 1.2% over the same period.
Mortgage buffers, measured as months of essential expenses covered by current account balances, eased slightly to 22 months from 22.5 months in the prior quarter. That remains well above the 19.2-month low recorded during the previous rate cycle. The median buffer, a better proxy for typical borrowers, sits at six months, matching pre-2022 levels.
Where the spending cuts are landing
The pullback is not uniform. Transport spending fell sharply, partly due to airfare refunds tied to Middle East travel disruptions. Stripping out transport, spending rose 0.5%, in line with the previous quarter.
Recreation and dining took the bulk of the remaining cuts. Mortgage holders reduced discretionary outlays more sharply than non-mortgage households, signalling that borrowing costs are reshaping choices at the margin. Younger customers aged 18 to 34 bucked the trend, lifting spending on dining, recreation and household furnishings.
Annual spending growth slowed to 2.9%, below recent quarters but still positive. Inflation ran at 4% for the year to May 2026, according to ABS quarterly estimates, above the RBA’s 2–3% target band but down from the peak.
Savings balances climb as rate expectations harden
Savings balances rose 8.3% year-on-year, with mortgage holders adding 1.8% over the quarter compared to 1.1% for those without a mortgage. The gap reflects expectations: over 72% of mortgage holders surveyed expect rates to rise further in the next 12 months.
The build in savings while spending slows suggests households are rationing discretionary purchases to maintain liquidity buffers, not burning through reserves to sustain consumption. That is consistent with controlled adjustment, not distress.
The risk is duration. If rates stay elevated for longer than borrowers anticipate, the capacity to keep trimming discretionary budgets without touching savings will narrow. Buffers provide runway, but they don’t eliminate the constraint.
Callout: The catch
Median buffers sit at six months, not 22. The average is pulled higher by wealthier households with large balances. For half of borrowers, the cushion is thinner, and another rate rise would compress discretionary spending further.
Rate expectations versus rate reality
The data supports a view that current restrictiveness is already tempering demand, reducing the case for further tightening in the near term. Inflation expectations, however, ticked higher for three consecutive weeks through late June, driven by renewed Middle East tensions and fuel price volatility.
The RBA’s August decision will settle which signal carries more weight: the household spending slowdown visible in transaction data, or the uptick in inflation expectations visible in survey data. The board retains a hawkish bias, and the gap between 4% inflation and the 2–3% target band leaves room for another move if expectations keep drifting.
Base case: rates hold in August, with the next move delayed until household spending data and inflation prints converge more clearly. Upside risk: inflation expectations harden and the board moves pre-emptively. Downside risk: spending cuts accelerate faster than anticipated, and the focus shifts to how quickly buffers erode if discretionary cuts exhaust their room.
What this means for serviceability
Borrowers with buffers above six months have scope to absorb another 25-50 basis point rise without material stress, assuming employment holds. Those closer to the median are already trimming non-essential spending and have less flexibility if rates move again.
If you are refinancing or extending, stress-test your cashflow against another rate rise and model how long your current buffer would last if discretionary cuts maxed out. The data shows households are adjusting rationally so far, but the adjustment is ongoing, not complete.
For property investors, serviceability will tighten further if rates rise, even if buffers remain adequate. Lenders are already applying higher assessment rates, and another move would push more borrowers into the zone where new purchases or refinances require either higher income or lower debt. If you are holding and rates stay flat, the pressure eases gradually as wages catch up. If rates rise again, the window for leveraging into additional stock narrows further.
Mortgage rate cuts hit 6.04%, but only if you switch lenders covers the refinancing trade-offs in detail.
The practical take
Mortgage buffers are holding, but the margin for error is shrinking. If you have a buffer below six months, treat the next 12 months as a window to build liquidity rather than increase leverage. If you are above the median, you have time, but another rate rise compresses that time faster than a flat-rate environment.
The household spending slowdown is visible, controlled and rate-sensitive. The question is whether it is enough to keep inflation on the path back to target without another RBA move. The answer will be clearer by August.
