Three Key Factors That Will Shape the RBA's Interest Rates Decision Next Week

Millions of Australian mortgage holders will be watching closely on Tuesday when the Reserve Bank of Australia hands down its latest interest rates decision, with the cash rate currently sitting at 4.35 per cent. While Australia's major banks broadly expect the RBA board to hold steady, a leading mortgage analyst says the call is closer than many assume — and three economic indicators will be central to the outcome.

The RBA has already raised rates three times this year, and governor Michele Bullock has declined to rule out further increases as inflation continues to sit above the central bank's target band of 2 to 3 per cent. For borrowers already under pressure, the stakes heading into Tuesday's announcement are high.

Why Inflation Remains the RBA's Biggest Concern

Inflation is the first and most closely watched indicator ahead of the interest rates decision. The most recent data from the Australian Bureau of Statistics showed headline inflation eased from 4 per cent to 3.8 per cent in June, while the trimmed mean — which strips out volatile price movements — held steady at 3.6 per cent.

Data insights director at Canstar, Sally Tindall, described the June figures as "perhaps better than we were expecting, but still a long way from target." She warned that time is becoming a critical factor in the RBA's fight to bring prices under control.

"They've got a clock ticking in the background, particularly when it comes to inflation," Tindall said. "The RBA board has repeatedly said that time is a factor in this battle with inflation because the longer we take to get back down, the harder it becomes, and the more entrenched inflation becomes."

The RBA noted in June that higher fuel and commodity costs were flowing through into housing and construction. Governor Bullock acknowledged Australia was already dealing with an inflation problem before fresh global pressures — including conflict in the Middle East — added further complexity. Geopolitical uncertainty affecting global oil supply has been a notable complicating factor in inflation forecasts; for background on how international financial flows intersect with such disruptions, see the Foreign exchange market. Our earlier coverage of the prospect of an interest rate rise amid budget relief measures also outlined some of the broader economic pressures at play.

Unemployment Figures Are Higher Than Expected

The second major indicator is the labour market. Australia's unemployment rate reached 4.4 per cent in June — just below a recent peak of 4.5 per cent recorded in April, which represented the highest point forecast through to 2026. Governor Bullock has publicly noted that unemployment figures have come in above expectations.

Tindall described the unemployment rate as "a critical data set for the RBA," but cautioned that the current level of 4.4 per cent is not high enough on its own to trigger an alarm. The RBA's mandate requires it to support full employment — meaning as many Australians in work as possible — without stoking excessive inflation, a balance that becomes increasingly difficult to strike as both indicators remain elevated.

Household Spending Offers a Mixed Picture

The third factor is household spending, which provides the RBA with a gauge of how ordinary Australians are managing their finances under the weight of cost-of-living pressures and higher mortgage repayments. In June, household spending rose 0.8 per cent month-on-month.

However, Tindall cautioned that this data can be difficult to read clearly. "It's difficult to isolate in this data the families that are doing it incredibly tough versus the ones that aren't really sweating from the economic pressures at the moment," she said. The aggregate figure can obscure sharp divergences in financial experience across Australian households.

What to Expect on Tuesday

All four of Australia's major banks — Commonwealth Bank, Westpac, NAB and ANZ — are forecasting that the RBA board will keep the cash rate on hold at 4.35 per cent when it meets Tuesday. Despite that consensus, Tindall's assessment suggests the decision is not a foregone conclusion, with persistent inflation, a softening labour market, and patchy household data all adding layers of uncertainty to the board's deliberations.
