THE RBA’S MORTGAGE HAMMER: HOW MUCH MORE CAN AUSTRALIA’S PROPERTY MARKET TAKE?

PROPERTY NOISE ANALYSIS: Another rate rise. Falling property values. Fewer sales. Australians are being asked to absorb more financial pain while the housing market is already retreating. Is the Reserve Bank applying necessary medicine, or pushing the adjustment too far?

The Reserve Bank of Australia has raised the cash rate another 0.25 percentage points to 4.85%, delivering a fresh blow to borrowers and prospective buyers.

The 3 November decision takes the benchmark to its highest level since 2008. For households already balancing mortgage repayments against rising living costs, the distinction between a widely expected decision and an affordable one is painfully clear.

An expected rate rise still costs money.

It still reduces what some buyers can borrow.

And it arrives in a property market that was losing momentum well before this latest announcement.

The uncomfortable question is whether the RBA is successfully cooling demand or increasing the risk of a deeper housing downturn than Australia needs.

Australian property prices were already falling before this hike

The latest housing figures give that question urgency.

Cotality’s national dwelling value index fell 1.2% in October. Values were 2.8% lower than a year earlier and 6.7% below their March peak, according to Westpac’s analysis.

Preliminary sales estimates were also weak: transactions over the rolling three-month period were down 22.5% from a year earlier.

That is a market experiencing pressure on both prices and activity.

Those measures describe different problems.

Falling values affect equity and expectations. Falling sales affect the ability of households to move and the income of businesses that depend on transactions.

A homeowner might tolerate a lower valuation while staying put. Someone who needs to relocate, separate, settle an estate or sell because their circumstances have changed has less flexibility.

For those households, the downturn is a practical financial problem, rather than a number in a monthly report.

Why the RBA is still raising interest rates

Inflation remains the central bank’s problem.

Australian Bureau of Statistics figures show annual CPI inflation increased to 4.3% in September, from 4.0% in August.

The trimmed mean, which seeks to reduce the influence of unusually large price movements, also rose to 3.6%, from a revised 3.5%.

Those figures complicate the argument that the RBA should simply stop tightening because housing is weakening.

Persistent inflation damages purchasing power. It makes household budgets harder to manage and can leave businesses uncertain about costs and pricing.

However, recognising the inflation problem does not settle the question of how much additional tightening is appropriate.

The legitimate debate is about the balance of risks: whether another increase delivers enough additional inflation control to justify its effects on households, investment and employment.

Housing pain is one way higher rates affect the economy

The RBA’s own explanation of monetary policy describes how changes in interest rates flow through spending and investment.

Higher borrowing costs can discourage purchases and reduce demand. The effects take time, and their size is uncertain.

Housing is particularly exposed because large purchases usually depend on substantial debt.

A higher mortgage rate can change whether a buyer qualifies, what they can offer and how much income remains after repayments.

For an existing borrower, the same increase can mean less spending elsewhere.

That creates a difficult political and economic reality: household restraint is part of how monetary policy works.

But households are entitled to ask how much restraint is enough.

What another 0.25 percentage points can cost

The cash rate is not the mortgage rate. Lenders determine their own pricing, and individual borrowers will experience changes differently.

Still, an illustration shows why another apparently small increase matters.

Assume a principal-and-interest mortgage with 30 years remaining, monthly repayments and a mortgage rate increasing from 6.00% to 6.25%.

Property Noise calculations, rounded to the nearest dollar. These are illustrative mortgage rates, not lender quotes. They assume the full increase is passed through and exclude fees, offsets and other loan features.

For the hypothetical A$750,000 borrower, that is approximately A$1,450 more each year.

Some households can absorb it. Others must cut spending, draw down savings or reconsider plans.

The effect depends heavily on the borrower’s starting position. The same increase can be manageable for one family and deeply disruptive for another.

The first-home buyer trap: cheaper homes, tighter borrowing

Falling prices should help aspiring owners. But lower prices do not automatically make buying easier when mortgage rates are increasing.

Consider a hypothetical buyer whose target property falls from A$800,000 to A$760,000.

The price is lower. Yet if their approved borrowing limit falls, living expenses rise or their savings are being consumed by rent, the purchase may remain out of reach.

That is the frustration at the centre of this downturn.

A market can become cheaper while remaining difficult to enter.

Buyers with substantial deposits and secure incomes may gain negotiating power. Buyers relying on maximum borrowing capacity may find that the opportunity disappears when the lender assesses the application.

Calling every price decline an affordability victory overlooks that difference.

Sydney, Brisbane and Perth show the downturn is spreading

The weakness is not confined to one city.

Westpac’s October analysis recorded monthly dwelling value falls of:

• Brisbane: 2.0%.
• Perth: 1.7%.
• Sydney: 1.6%.
• Adelaide: 1.2%.
• Melbourne: 0.8%.

Sydney values were down 9.4% over the year, while Melbourne was down 7.6%. Adelaide remained 3.7% higher annually despite its October fall.

These differences matter.

A monthly decline in a city following substantial earlier growth is not equivalent to the experience of a market that has struggled for years.

There is no single Australian homeowner’s experience. Purchase date, location, debt and personal circumstances determine how much financial pressure a falling market creates.

Nevertheless, weakness across several major cities makes it harder to dismiss the downturn as an isolated local correction.

Falling equity can make moving harder

A property price fall is not automatically a realised loss. Owners who stay in their homes do not receive a bill for the change in valuation.

But equity still matters.

Imagine a property purchased for A$900,000 with a A$720,000 mortgage. Ignoring transaction costs and subsequent repayments, the buyer begins with A$180,000 in equity.

If the property’s value falls 10% to A$810,000 while the loan remains A$720,000, that equity falls to A$90,000.

The property has declined 10%. The illustrative equity position has declined 50%.

That is how leverage magnifies the effect.

It can complicate refinancing, reduce the deposit available for another purchase and leave a household with fewer options.

This example does not establish that widespread negative equity is occurring. It explains why even an orderly downturn can matter greatly to recent buyers.

Investors face a cash-flow squeeze

Investors also have to reconcile falling asset values with the cost of holding the property.

Higher interest expenses can reduce the amount left after rent, maintenance, insurance, rates and management costs.

An investor may remain confident about long-term demand and still decide that purchasing another property makes little financial sense today.

Others may delay renovations or reassess whether to retain an existing investment.

It is equally important not to assume landlords can simply pass every interest increase to tenants. Achievable rents depend on local demand, supply, tenant affordability and applicable rules.

A landlord’s higher mortgage payment does not automatically create an equivalent increase in rental income.

The financing squeeze can therefore affect investment decisions even where demand for accommodation remains substantial.

The damage spreads beyond homeowners

A quieter property market reaches well beyond the vendor and purchaser.

A delayed transaction can mean delayed work for conveyancers, mortgage brokers, inspectors, removal companies and other businesses.

Some buyers postpone furniture purchases or renovations when they do not move. Some existing borrowers cut discretionary spending to protect mortgage repayments.

Property Noise has previously examined how a housing correction can put real estate agents under pressure.

The important issue is transaction dependence. Businesses built around regular sales can face pressure even when most homeowners remain financially secure.

A housing market does not need a banking crisis to produce serious consequences for people working around it.

Even wealthy sellers must adjust expectations

At the other end of the market, substantial wealth does not guarantee that a buyer will meet a seller’s preferred price.

Property Noise’s coverage of Simon Beard resetting expectations for his Gold Coast penthouse illustrates the distinction between a price ambition and a completed deal.

One luxury campaign cannot prove what is happening across Australia.

It does, however, highlight a principle that becomes more important in a weaker market: sellers compete for buyers whose willingness and ability to pay may have changed.

A previous valuation, an earlier offer or a neighbour’s boom-time result cannot compel today’s purchaser to pay the same amount.

Could higher rates also weaken future housing supply?

The potential impact on construction deserves attention.

More expensive finance can make development harder to justify, particularly when expected selling prices are weakening.

If a project’s funding costs increase while its likely revenue falls, the developer may delay, redesign or abandon it.

That creates a potential tension. Tighter policy can weaken current housing demand while also making some future supply less viable.

It does not follow that every delayed project would have been built profitably at lower rates. Land costs, infrastructure, approvals, labour and materials also influence delivery.

But the risk warrants scrutiny, especially when long-term housing availability remains part of the affordability debate.

Interest rates cannot resolve those supply constraints on their own.

The strongest criticism is about timing

The most credible argument against further tightening is not that inflation should be ignored.

It is that monetary policy operates with delays.

Households and businesses adjust over time. The RBA acknowledges uncertainty around both the timing and strength of those effects.

That means policymakers must make decisions before the full consequences of earlier decisions are visible.

Wait too long and inflation may become harder to control. Tighten too far and the eventual reduction in demand may be greater than intended.

The October housing figures cannot settle that debate. They do show why the risk of excessive tightening deserves serious consideration.

Falling sales and values are evidence that an important part of the economy is already adjusting.

Is the RBA destroying Australia’s property market?

“Destroying” captures the anger of borrowers who feel they are being squeezed from every direction.

As a factual description of the entire market, it goes further than the evidence supports.

Australia still has buyers, sellers, functioning lenders and substantial differences between regions and households. Lower property prices can also create opportunities and reduce the entry cost for some purchasers.

The RBA is not the sole influence on housing. Employment, incomes, taxation, lending decisions, population changes and housing supply also matter.

But higher interest rates are a powerful source of pressure, and another increase adds to that pressure at a vulnerable point in the cycle.

The harder question is whether the additional economic benefit will justify the additional household cost.

Property Noise’s view: borrowers deserve more than another dose of pain

The RBA has a genuine inflation problem to address. It should not be expected to protect every property valuation or guarantee capital gains.

Equally, a housing downturn should not be treated as painless simply because it remains orderly.

Recent buyers can lose financial flexibility. Would-be buyers can lose borrowing capacity. Businesses can lose transactions. Households can cut spending long before they miss a mortgage payment.

Our concern is that repeated tightening risks deepening those pressures before the full effect of earlier increases is understood.

The housing market is already responding.

The RBA must now demonstrate that the benefits of demanding still more restraint outweigh the risk of pushing that response too far.
