Catching up for early morning coffee with locals, it is almost impossible to avoid the topic of interest rates.
One person at the table had a loan of around $2 million. He said another rate rise would cost him thousands more each year. The exact number depends on the loan structure, but the point is simple: when rates move, household budgets move with them.
That conversation raises a bigger question.
How can Australia talk about a housing shortage, affordability, and the need to build more homes, while also using higher interest rates to slow demand, reduce borrowing capacity, and make development harder?
That is the contradiction sitting at the centre of the Australian property market.
The Reserve Bank of Australia’s Monetary Policy Board meets eight times a year to decide the cash rate. The cash rate is the overnight rate banks pay to borrow funds from each other, and it influences other interest rates in the economy, including mortgage and deposit rates. The RBA’s objectives are to keep inflation between 2% and 3% and support sustained full employment.
From a central banking perspective, the system has logic.
From a property market perspective, it creates a different problem: housing is a long-term asset being managed through short-term rate decisions.
The Cash Rate Is Powerful — But Blunt
The cash rate is not your mortgage rate, but it is the starting point.
When the RBA raises the cash rate, banks generally raise home loan rates. Borrowers have less disposable income. Buyers can borrow less. Businesses become more cautious. Demand slows.
That is the intended mechanism.
At its May 2026 meeting, the RBA lifted the cash rate by 25 basis points to 4.35%. The RBA said inflation had picked up materially in the second half of 2025, with higher fuel and commodity prices adding to inflation pressure. The RBA also noted early signs that firms facing cost pressure were looking to increase prices.
The difficulty is that housing is not like most other consumer spending.
You can delay buying a new car. You can reduce discretionary spending. But people still need somewhere to live.
That is why interest rates hit property so directly. They do not just reduce spending. They change who can buy, what they can pay, whether investors can hold, and whether developers can make projects work.
The Wealth Boom That Changed Australia
Since I began my real estate career, I have watched property create enormous wealth for ordinary Australians.
Many owners who bought well and held through different cycles have become multi-millionaires, not because they were speculators, but because they owned property through one of the strongest wealth-creation periods Australia has seen.
The COVID period accelerated that wealth effect.
According to the Australian Bureau of Statistics, the total value of Australia’s residential dwellings rose from $7.849 trillion in December 2020 to $12.307 trillion by December 2025. In plain English, this is the estimated combined value of all residential property in Australia — houses, units, townhouses, villas and apartments. Over that five-year period, the national housing asset pool increased by about $4.46 trillion.
By December 2025, Australia had approximately 11.45 million residential dwellings. When the ABS divides the total value of the housing stock by the number of dwellings, the mean, or average, dwelling value comes to $1.074 million. That does not mean every home is worth $1.074 million. It is an average across the entire country and every property type — from regional units to Sydney waterfront houses.
The million-dollar-home figure tells the story even more clearly. Cotality data reported by the ABC found that 34.4% of Australian dwellings were valued at $1 million or more in April 2025, compared with just under 10% in April 2015. Using the ABS dwelling count of 11.45 million, that suggests roughly 3.94 million Australian homes are now valued at $1 million or more. This is an estimate, because the Cotality percentage is from April 2025 and the ABS dwelling count is from December 2025, but it gives the scale of the shift.
In Sydney, the numbers are more striking. The same Cotality analysis found that 64.4% of Sydney dwellings were worth $1 million or more in April 2025.
That is the positive side of property. It created equity, funded retirements, helped parents support children into the market, and turned many ordinary homes into multi-million-dollar assets.
But it also created the affordability problem we are now living with.
When millions of homes sit above $1 million, the market becomes heavily dependent on credit. Buyers are no longer just asking whether they like a property. They are asking whether the bank will allow them to borrow enough to buy it.
That is why the cash rate matters.
Higher interest rates do not change the house, the street or the view. They change the buyer’s borrowing power. And when borrowing power changes, the market changes with it.
When the Market Turns, Forced Sellers Feel It First
A rising market makes people feel wealthier.
They borrow against equity. They upgrade. They buy first and sell later. They help children with deposits. Investors accept thinner yields because they expect future capital growth. Developers buy land at prices that only work if values keep rising.
Then the cost of money changes.
A vendor who chooses to sell has control. A vendor who is forced to sell often does not.
That pressure can come from higher repayments, a failed refinance, business stress, divorce, death, a bridging loan, a stalled development, or a buyer who cannot settle.
This is where the market becomes unforgiving.
The property may be the same. The street may be the same. The view, the land, and the floorplan may all be the same.
But if the buyer’s finance has changed, the value conversation changes as well.
The Serviceability Problem — What It Means in Real Life
A home loan is not approved simply because a borrower can afford the repayment at today’s interest rate.
Banks test whether the borrower could still manage the loan if rates were higher. This is called serviceability. The bank looks at income, tax, living expenses, existing debts, credit cards, dependants, and then applies a higher assessment rate to see whether the loan is still affordable.
APRA has also tightened the rules around highly leveraged borrowing. From February 2026, banks must limit new residential mortgage lending where a borrower’s total debt is six times their income or more. These higher debt-to-income loans can make up no more than 20% of new lending, measured separately for owner-occupiers and investors.
A simple example explains it.
If a couple earns $200,000 per year before tax, six times their income is $1.2 million. If they want to borrow $1.3 million, they are above that threshold.
That does not automatically mean the bank must say no. But it does mean the loan falls into a more restricted category. The bank may reduce the approved loan amount, require a larger deposit, apply stricter conditions, or decline the loan if it has already reached its limit for higher-debt lending.
This is where the property market feels the impact.
A buyer may like the property. They may have a deposit. They may even feel comfortable with the repayment. But if the bank will not support the loan, they cannot pay the price they intended to pay.
That is how serviceability affects property values.
It does not change the home, the street, or the view. It changes the buyer’s borrowing power.
Mortgage Stress — The Pattern Beneath the Market
Mortgage stress does not usually appear all at once. It builds in stages.
First, households absorb higher repayments by cutting discretionary spending. Holidays are postponed. Renovations are delayed. Dining out reduces. Retail spending weakens. This is often the first sign that rate rises are working through the economy.
The second stage is more serious. Borrowers draw down savings, reduce extra repayments, use offset buffers, refinance, extend loan terms, or try to move from principal-and-interest to interest-only.
The final stage is where stress becomes a property-market issue: forced selling. This usually occurs when a borrower cannot refinance, cannot reduce spending further, and cannot maintain repayments without selling the asset.
The RBA’s March 2026 Financial Stability Review was measured rather than alarmist. It said most households and businesses were generally well placed to weather higher interest payments and cost pressures. It also said severe mortgage stress had declined since mid-2024 and remained small, with housing loan arrears low and around pre-pandemic levels.
That matters.
Mortgage stress does not mean the whole banking system is about to fail. It means a growing group of households may be forced to make harder decisions if rates stay higher for longer.
For property, the pattern is important. Buyer behaviour changes first. People become more cautious. They borrow less. They negotiate harder. They delay decisions.
Then seller behaviour changes. Some owners hold back because they do not want to meet the market. Others have no choice because they need to reduce debt.
That is when the market becomes more selective.
The Housing Shortage Contradiction
Australia says it needs more homes.
The National Housing Accord target is 1.2 million new well-located homes over five years from 1 July 2024. The Commonwealth has also committed funding to help states and territories support additional housing delivery.
That ambition is necessary. Australia does have a housing shortage.
But here is the contradiction.
Higher rates may reduce buyer demand, but they also raise development finance costs. They make projects harder to fund, presales harder to secure, and land values harder to justify. They reduce the very feasibility needed to deliver new supply.
The National Housing Supply and Affordability Council warned in its 2025 report that new supply was falling short of demand. It estimated 177,000 dwellings were completed in 2024, compared with underlying demand of 223,000, and forecast 938,000 new dwellings over the Housing Accord period — leaving a projected shortfall of 262,000 against the 1.2 million target.
So we are trying to solve a housing shortage with a tool that can make housing delivery harder.
That does not mean the RBA is wrong to fight inflation.
It means the cash rate cannot be the only lever.
The Eight-Times-a-Year Problem
The RBA’s Monetary Policy Board meets eight times a year after key economic data on inflation and activity. The decision is announced publicly after each meeting.
That may be appropriate for monetary policy.
But property ownership is not an eight-meetings-a-year decision.
People buy homes on 25- or 30-year mortgages. Developers plan projects over many years. Families make decisions around schools, work, children, ageing parents and retirement. Investors calculate long-term income and capital growth.
Yet every few weeks, the market waits for another rate decision.
Will repayments rise again?
Will buyers pull back?
Will banks change assessment rates?
Will confidence hold?
Will developers pause?
That uncertainty has consequences.
Property needs confidence. Development needs certainty. Households need to plan.
When the entire market is repeatedly waiting for the next cash-rate signal, long-term decision-making becomes harder.
Why Australia Feels Rate Rises Faster
Australia is not alone in fighting inflation, but our mortgage system makes households more exposed than in some other countries.
In the United States, 30-year fixed-rate mortgages are common. A homeowner who locked in a low fixed rate during COVID may not feel higher rates unless they refinance or move.
Australia does not have that structure in any meaningful way. Most local fixed-rate home loans run for much shorter terms, and long-term 20- or 30-year fixed-rate products are not generally available in the same way they are in the US.
This is why Australian households feel the cash rate so quickly.
In the United States, the central bank can raise rates and many existing borrowers are protected.
In Australia, rate changes move through household budgets much faster.
That is not just a banking detail. It shapes the entire property market.
Are There Smarter Ways to Control Inflation?
Yes — but they require political discipline.
The cash rate is powerful, but it is blunt. It reduces demand by making money more expensive. That can work when inflation is driven by excessive spending.
But not all inflation is driven by excessive spending.
If inflation is coming from fuel, energy, insurance, construction costs, supply chains, weak competition, labour shortages or housing shortages, higher mortgage rates do not directly fix the source of the problem.
They slow demand.
They do not build homes.
They do not make builders more productive.
They do not reduce planning delays.
They do not create more tradespeople.
They do not lower insurance premiums.
That is why the inflation conversation needs to be broader than the RBA.
Government has other tools: fiscal discipline, supply-side reform, better infrastructure delivery, competition policy, targeted cost relief and macroprudential lending rules.
The RBA can change the price of money.
Government must fix the structure around it.
What This Means for Buyers
For buyers, the question is no longer simply, “What can I buy?”
The better question is, “What can I safely afford if rates stay higher for longer?”
A buyer needs to understand repayments, bank assessment rates, insurance, strata, land tax, maintenance, income risk and resale liquidity.
In a cheap-money market, mistakes were often hidden by growth.
In today’s market, mistakes are more expensive.
What This Means for Sellers
For sellers, this market requires realism.
The buyer today is not the buyer of 2021.
They are more cautious, more finance-constrained and more selective. They are not just asking whether they like the property. They are asking whether the bank will support the number.
Good property still sells.
But pricing must reflect today’s borrowing environment, not yesterday’s emotion.
What This Means for Developers
Developers are facing one of the hardest combinations I have seen.
Land is expensive. Construction is expensive. Finance is expensive. Buyers are more cautious. Presales are harder. Government wants more supply, but the numbers often do not work.
This is why we may see more developer stress.
Not because Australia does not need housing.
It does.
But needing housing and being able to deliver housing profitably are two different things.
The Real Contradiction
Australia is trying to do three things at once.
It wants to reduce inflation.
It wants to improve housing affordability.
It wants to build more homes.
Higher interest rates may help with the first goal, but they can work against the second and third. They reduce borrowing power, which makes affordability harder for buyers. They increase development finance costs, which makes new supply harder to deliver. They reduce confidence, which makes households and builders more cautious.
That is the contradiction.
The RBA is doing its job with the tool it has.
But the country needs more tools than that.
Conclusion
The cash rate is not just an economic number.
In Australia, it reaches directly into the property market.
It changes borrowing capacity, repayments, sentiment, feasibility and what buyers can pay.
But housing is a long-term asset being managed through a short-term rate cycle.
That is the problem.
We need more homes, but higher rates can make them harder to build. We need affordability, but higher rates reduce borrowing power. We need inflation under control, but interest rates alone cannot fix housing supply, construction costs, planning delays, weak competition or productivity.
After 35 years in real estate, I have seen the same lesson repeat across different cycles.
When credit expands, markets rise.
When credit tightens, the market becomes more selective.
The next stage of the property market will not be about hype. It will be about income, serviceability, debt, quality, location and timing.
And for buyers, sellers, investors and developers, understanding how the cash rate moves through the property system is no longer optional.
