RBA Rate Hike to 4.60%: Why History Says Don’t Panic
Quick answer: No — a rate rise is not a reason to stop buying property. The RBA’s cash rate hit 4.60% on 29 September 2026, the highest level since 2011. But 50 years of RBA and property-price data show interest rates and house prices don’t move in opposite directions — from 2009 to 2011, the cash rate rose steadily while Sydney and Melbourne house prices rose alongside it. The real risk isn’t buying during a hike. It’s waiting indefinitely for a rate that feels “safe”.
What Happened: The RBA’s September 2026 Rate Decision

For a mortgage holder, each rise adds to monthly repayments, and the immediate reaction across the market is predictable: headlines about buyers pulling back and advice to “wait until rates come down”. That advice isn’t grounded in what actually happens to property prices when the cash rate rises — it’s grounded in how the rise feels.
The Myth: “Rate Hikes Crash Property Prices”
Most people assume the relationship works like this: rates go up → borrowing gets more expensive → demand falls → prices fall. It’s intuitive, and it’s backwards.
In The Housing Bubble Myth, property investment author and Integrity Property Investment founder Daimien Patterson makes the case using RBA cash rate history alongside CoreLogic price data: house prices are a factor the RBA reacts to when setting rates, not a result the RBA controls by moving them. As Patterson puts it, “It’s not interest rates affecting house prices; it’s house prices affecting interest rates.” The cash rate is set with reference to inflation, and housing costs are a contributor to that inflation figure — so a hot property market is often a cause of rate rises, not a casualty of them.
The Evidence: What Actually Happened Last Time Rates Rose Like This
The clearest test of the myth is the period right after the Global Financial Crisis. From 2009 to 2011, the RBA cash rate climbed steadily as the economy recovered — and Sydney and Melbourne house prices climbed at the same time, not in spite of it.
2009–2011: Cash rate rising. Sydney & Melbourne prices rising alongside it.
2026: Cash rate at 4.60%, rising, the highest since 2011. History says the same pattern holds.
Zoom out further, and the pattern isn’t limited to one cycle. Over the past 50 years, the cash rate has moved up and down through recessions, the GFC, and mining booms — and house prices have kept trending in one direction: up. A single rate decision, including this one, has never been enough on its own to reverse that trend.
A Real Example: Investing Through the GFC
Daimien Patterson didn’t just study this period — he invested through it. In 2009, during the Global Financial Crisis, one of the most uncertain economic periods in living memory, he made $260,000 in capital growth in a single year, driven by declining interest rates and continued house price growth in the same window that the broader rate cycle was about to turn upward again.
The lesson isn’t “uncertainty is good”. It’s that uncertainty and opportunity have coexisted before, repeatedly, and waiting for the uncertainty to fully clear has historically meant waiting past the opportunity.
What Actually Protects You Through a Rate Hike
Rates will keep moving — up, then down, then up again. That’s not a forecast; it’s the RBA’s job description. The only outcome that’s guaranteed is what happens if an investor waits indefinitely for a rate that feels safe: nothing.
What protects an investor through a hike isn’t timing the market. It’s two things:
- A property that pays for itself from day one — positive cash flow means a rate rise is an inconvenience, not a threat to holding the asset.
- A cash buffer sitting in an offset account — built specifically to absorb repayment increases on exactly a day like this one.
That’s the whole strategy. Not timing. Preparation.
Frequently Asked Questions
Should I buy property when interest rates are rising in Australia? Yes, if the property is fundamentally sound. Historical RBA and property-price data show rate rises have not reliably caused price falls — from 2009 to 2011, rates and Sydney/Melbourne prices rose together. The decision should rest on the property’s cash flow and your buffer, not on the direction of the cash rate.
Do rising interest rates cause house prices to fall? Not reliably. House prices are one of the inputs the RBA considers when setting the cash rate, alongside broader inflation. Over the past 50 years, the cash rate has moved up and down through multiple economic cycles, while Australian house prices have continued to trend upward.
What happened to house prices the last time the RBA raised rates repeatedly (2009–2011)? The cash rate rose steadily over that period as the post-GFC economy recovered. Sydney and Melbourne house prices rose over the same period rather than falling.
What is the RBA cash rate as of September 2026? 4.60%, set on 29 September 2026. It was the fourth rate rise of 2026 and the highest cash rate since 2011.
What should property investors do instead of trying to time interest rate movements? Focus on buying a property that is cashflow-positive from settlement, and hold a cash buffer in an offset account sized for rate increases. This protects an investor through a hike regardless of when it happens, rather than depending on predicting it.

A rate rise doesn’t need to change your plans — but it’s worth understanding exactly what it means for your specific numbers before you decide either way.
