According to realestate.com.au, underlying inflation is creeping toward a two-year high, reigniting genuine concern that the Reserve Bank of Australia may need to lift the cash rate above its current 4.35% — a prospect that only weeks ago seemed firmly off the table.
What the Inflation Data Actually Shows
The latest figures show that underlying inflation — the measure favoured by the RBA precisely because it strips out volatile items like fuel and fresh food — is creeping back toward levels not seen in roughly two years. This is the measure that drove the RBA's rate hiking cycle in the first place, and it is the one that will determine whether the Board reaches for the lever again. The live cash rate currently sits at 4.35%, and with underlying inflation moving in the wrong direction, the Board's next decision carries more weight than markets had recently been pricing in.

The significance of underlying inflation moving higher at this point in the cycle cannot be overstated. The RBA's preferred trimmed-mean measure is designed to cut through noise and reveal the true direction of price pressure in the economy. When it rises after a hiking cycle has theoretically ended, it tells the Board that demand has not been cooled sufficiently — that households and businesses are still spending, and that the full effect of previous hikes has not yet transmitted through the economy in the way the Board modelled. A hike back on the table is not hysteria; it is the data doing its job.
Historical context matters here. The last time underlying inflation was at or near this trajectory, the RBA was actively hiking. The Board has shown repeatedly that it is willing to move when the data compels it, even if market pricing and bank economists are forecasting holds. That precedent is now front of mind for every borrower with a floating rate.
How Property Markets Are Pricing the Risk
Australian property markets had been operating on an implicit assumption: that 4.35% was the ceiling, and that rate cuts were a matter of when, not if. That assumption is now materially in question. When the prospect of further tightening enters the market, buyer confidence softens and vendors find the pool of qualified, finance-approved buyers thinner than expected. These are not abstract dynamics — they play out at the street level, suburb by suburb, in the weeks following any credible hike signal.
Investor calculations are acutely sensitive to the rate environment. Gross rental yields across most Australian capital cities are already compressed relative to the cost of debt at 4.35%. If borrowing costs rise further, negatively geared property becomes harder to justify on a cash-flow basis, and the pipeline of investor demand that has supported prices in tightly held inner-city and middle-ring markets begins to thin. The current inflection point is one of the more consequential in recent memory for those assessing Australian asset allocation.
Owner-occupiers in the market right now face a genuine strategic question. Those with pre-approvals based on current serviceability assessments may find their borrowing capacity recalculated if the RBA moves. APRA's serviceability buffer requires lenders to assess borrowers at the prevailing rate plus 3 percentage points — but that buffer does not eliminate the real-world impact of higher repayments on household budgets. Buyers stretching to their approved limit should model for a scenario where their variable rate rises by at least a further 25 basis points from here.
When underlying inflation resists the full weight of a hiking cycle and starts climbing again, the conventional assumption that rates have peaked deserves serious scrutiny. With the cash rate sitting at 4.35%, the RBA's track record of acting on data rather than market consensus means no borrower should treat the current rate as a guaranteed ceiling.
Background: The RBA's Inflation Target and Why It Matters for Sellers
The RBA's mandate is to keep underlying inflation within a 2–3% target band over the medium term. When inflation drifts toward the upper bound or beyond, the standard policy response is tighter monetary conditions — higher rates — until demand eases enough to bring price growth back under control. This cycle has been unusually prolonged by post-pandemic supply disruptions, persistent services inflation, and a tight labour market that has kept wages growing faster than historical norms. Understanding this framework is essential for anyone selling property in the current environment, because the rate outlook directly shapes buyer borrowing capacity and therefore the prices vendors can realistically achieve.
Sellers considering their timing would do well to assess their position carefully. A property sold before any further RBA action is marketed into a buyer pool with today's borrowing capacity; a property listed after a hike faces a pool that is by definition more constrained. This dynamic is one reason that experienced vendor advocates — as explained in the APF guide to Vendor Advocacy Explained — emphasise the importance of timing strategy rather than simply selecting the first available agent. Market conditions that shift mid-campaign can be costly if the campaign strategy was not calibrated to absorb that risk.
What Buyers, Sellers, and Investors Should Do Now
The most constructive response to genuine rate uncertainty is preparation, not paralysis. Buyers should model their repayment capacity at 4.60% and at 4.85% — not because either outcome is certain, but because knowing your personal floor is essential before committing to a purchase at current prices. Those using offset accounts should be maximising balances now; even modest offset balances reduce effective interest exposure and provide a buffer if rates move higher. For a detailed breakdown of broader market context for positioning decisions, the APF guide on Australian property statistics is a useful reference point.
Investors with existing portfolios should reassess their debt serviceability under a higher-rate scenario. Properties that were marginally cash-flow positive at 4.35% may tip negative at 4.60%, changing the tax and holding-cost calculus. Selling into the current market — before any further rate action — may be preferable to holding through another hike for investors whose portfolios are already stretched. For those considering new purchases, the risk-reward of buying at current prices into a potential
