SYDNEY, NSW – 29 Sept, 2026 – The Reserve Bank of Australia’s decision on 29 September to lift the cash rate by 25 basis points to 4.60 per cent — its fourth increase this year and the highest level since 2011 — has been widely framed as more pain for borrowers and a further blow to an already softening housing market. That reaction is understandable. Yet from a longer-term perspective, this move is precisely the kind of discipline the Australian property market has required.
For too long, residential values in many markets operated on the assumption that prices could only move in one direction. Easy credit, strong population growth and successive waves of investor demand created conditions in which speculative excesses were allowed to build. The current tightening cycle is forcing a necessary reset: it is squeezing out the froth and returning the market to something closer to sustainable fundamentals.
Cooling an overheated narrative
A market that rises without interruption is not a healthy market. It becomes one in which first-home buyers are progressively priced out, investors chase capital growth rather than yield or utility, and household balance sheets become increasingly leveraged against optimistic assumptions. The series of rate rises through 2026, culminating in this week’s move to 4.60 per cent, is cooling that dynamic. Borrowing capacity has been reduced, auction clearance rates have stayed subdued, and vendors in overheated segments are being forced to adjust expectations.
This is not a crash engineered by policy error. It is the deliberate removal of excess. Prices that had run well ahead of incomes and rents are now facing a more realistic cost of capital. In that sense, the RBA is performing a public service that pure market forces alone might have delayed until a more disorderly correction arrived.

Squeezing the speculative bubble
The most valuable outcome of higher rates is the pressure they place on purely speculative positions. Investors who bought on the premise of endless capital growth with minimal cash-flow support are finding the arithmetic less attractive. Highly leveraged purchasers are discovering that serviceability buffers exist for a reason. The result is a gradual deflation of the speculative premium that had attached itself to many assets, particularly in the upper end of Sydney and Melbourne.
A cooler market also improves the quality of new supply decisions. When the cost of capital is artificially low, marginal projects proceed that later struggle. When rates are restrictive, only the stronger proposals stack up. Over time, that should support a healthier development pipeline rather than another cycle of overbuilding followed by distress.
The necessary discomfort
None of this is painless. Mortgage holders will feel higher repayments. Transaction volumes will remain muted for a period. Some households will face genuine stress. Yet the alternative — allowing inflation to remain embedded while property prices continued their previous trajectory — carried greater long-term risks to financial stability and intergenerational equity.
The RBA has made clear that further tightening remains possible if inflation does not respond. That hawkish stance itself reinforces the message: the era of assuming that rates would always accommodate rising house prices is over. For the property market, that clarity is ultimately constructive.
Healthy markets do not only go up. They adjust, reprice, and clear excesses. Tuesday’s decision advances that process. The discomfort is real, but so is the opportunity to rebuild on more solid ground.
