Results come in materially stronger than expected, but what's driving the surge?
The Australia Bureau Statistic (ABS) Monthly Household Spending Indicator (MHSI) for September 2026 showed spending rose 0.6% for the month, against market forecasts of 0.2%, and was up 6.8% year-on-year.
The result was materially stronger than the zero monthly growth forecast of one major bank and broader market expectations – a surprise that has complicated the rate outlook heading into the new year.
The drivers behind the rise
A large chunk of September’s gain came from fuel, which jumped 5.4% in the month after the federal fuel excise relief ended in early August, and from transport costs tied to interstate AFL finals travel.
Health spending also spiked, mostly due to a late flu season pushing people toward GP clinics and pharmacies. These are not signs of a household feeling flush. They are unavoidable costs that happened to land in September.
CreditorWatch chief economist Ivan Colhoun (pictured) offered a nuanced read of the data. “Petrol price rises and interstate AFL finals flatter September household spending,” he said, adding that the transport component in particular “can’t be interpreted as strength”. He noted that food, clothing, and homewares were all soft, though some of that weakness likely reflects consumers holding off ahead of Black Friday, a seasonal shift that is increasingly skewing monthly reads.
Discretionary spending remained solid at 6.9% annually, with households still willing to spend on live entertainment and recreation. But the composition of September’s result points to spending driven by necessity and event-linked activity, not broad consumer confidence.
CBA senior economist Ashwin Clarke said the result was “materially stronger than both we and the market expected” – and the continued strength in annual discretionary spending is likely to keep the RBA concerned that even tighter monetary policy may be needed heading into the new year.
A consumer that continues to spend above trend reduces the RBA’s urgency to ease, after all, and if the spending resilience continues into the December quarter, the case for cuts in early 2027 weakens further.
For brokers’ clients, holding variable rate loans or approaching refinancing will need to plan around a higher-for-longer environment for longer than many had hoped.
The rate question every broker is asking
Here is what makes this data complex to read for the mortgage industry: the September MHSI almost entirely predates both the September and November RBA rate rises. In other words, Australian households had not yet felt the full impact of those increases when these figures were recorded.
As Colhoun observed, the key question is how consumer spending fares over coming months – not what it did before the latest tightening cycle landed. Higher fuel prices, reduced housing turnover, and squeezed household disposable income are all expected to slow growth in discretionary spending categories from here.
CBA’s Clarke echoed that view, noting that households are only beginning to absorb higher mortgage repayments from the September rate rise, with the November increase still feeding through. The full picture will only become clear in the data that follows.
The RBA, for its part, is expected to remain on hold at its December 2026 meeting, with the Governor’s recent press conference signalling the Board intends to observe how the economy performs in the wake of the two most recent increases before moving again.
The September spending data is a reminder that the economy is more resilient than many expected, but that resilience is part of the problem. It reduces the pressure on the RBA to ease and keeps the case for rate cuts further out on the horizon.
Borrowers on variable rates, or those refinancing in the near term, should be counselled accordingly. The data that matters most will arrive over the next two to three months, as the full weight of 2026’s rate rises begins to show up in household budgets.
