RBA Rate Hike September 2026: What Past Hiking Cycles Did to Property Prices

Published 30 September 2026 · RBA decision 29 September 2026 · Housing data to August and September 2026 · Lender announcements as at 4pm AEST 30 September 2026 · Market pricing 29 September 2026

The last time Australia's cash rate sat this high, in October 2011, capital-city home values were a year into a 19-month slide. It ended only after the Reserve Bank started cutting. The RBA's September 2026 rate hike, announced on Tuesday, lifted the cash rate 25 basis points to 4.60%, the fourth rise this year. National values are already 3.6% below their March peak (Cotality), Sydney is 7.1% below its February peak, and the Board said it will raise again "if needed".

History gives investors a useful guide to what happens to property prices when the RBA raises rates, but not a rule. In the 1999–2000 cycle, house prices kept rising through 150 basis points of rises. In the other four cycles since 1994, headline price indexes fell between 0.9% and 9.1%, depending on the cycle and the index, and in 2010–12 and 2022–23 some capitals fell 12% to 20%. Prices peaked at or before the final rise in three of those four, and troughs often came around the time rate cuts became credible, though 1994–95 and 2022–23 show that isn't a reliable rule.

That guide has limits in 2026. The conditions that shortened the 2022–23 downturn are materially weaker: population growth is 1.4% against a 2.5% peak, unemployment is 4.6% against a 3.4% low, and fewer than 5% of loans are fixed against almost 40%. No earlier cycle had a legislated negative gearing change for new purchases of established homes, as 2026 does. Below, we set out the record cycle by cycle, test each condition against today, and turn the result into decisions for investors.

Then vs now: the conditions that shaped past downturns

Against 2022–23, five of the thirteen rows point to a deeper or faster downturn, four to a shallower one, and debt is about the same. Our view is that the labour market will decide which set dominates.

What did the RBA decide on 29 September 2026, and what does it cost investors?

What the Board said

"Inflation remains elevated and some of the upside risks flagged in August are materialising," the Board wrote, citing energy prices "much higher than had been assumed in the August forecasts". It noted that "housing prices have fallen in most capital cities and new housing loans have declined noticeably", and kept a tightening bias, ready to act "including increasing the cash rate target further if needed".

At the press conference (as reported in ABC News' live coverage), Governor Michele Bullock named housing as one of "a couple of downside risks", said "part of the downturn in the housing market has been related to interest rates", and called a recession "not our base case".

The day after the decision, the ABS monthly CPI for August (released 30 September) showed headline inflation jumping to 4.0% from 3.5%, driven by electricity (up 13.2% over the year) and automotive fuel (up 13.5%). The trimmed mean held at 3.6% for a fourth month, and rose 0.2% in the month after July's 0.5%. Our reading: the energy shock is lifting headline inflation, while the softer monthly core gives the Board some room before the September-quarter CPI on 28 October.

Who has passed the rise on

As at 4pm AEST on 30 September, Macquarie had confirmed a 0.25-point rise in variable home loan rates from 15 October, and Australian Mutual Bank, Teachers Mutual Bank and UniBank from 8 October. The big four (CBA, Westpac, NAB and ANZ) had not yet announced. After the May hike, all four passed the rise on in full, effective 15 May.

What it costs

Source: our calculations. Interest-only = loan × rate change ÷ 12. P&I uses a 30-year remaining term, 6.40% rising to 6.65% for this rise and an illustrative 5.65% rising to 6.65% for the four rises. Assumes full pass-through.

What it does to borrowing capacity

Cotality estimates the four 2026 rises have cut the borrowing capacity of a median-income household by "almost $90,000, equivalent to around a 9% decline in purchasing power". For a new investor loan the typical assessment rate moves from about 9.40% to 9.65% (a new-loan rate near 6.65% plus APRA's 3-point serviceability buffer). Holding income and expenses fixed, that lowers the maximum 30-year loan by about 2.1% (our calculation); actual results vary by lender, income, expenses, existing debt and loan term.

In 2022 the RBA's Jonathan Kearns noted that "only around 10 per cent of borrowers take out a loan close to their maximum possible size", which is why capacity arithmetic overstates the direct price effect.

What markets and economists expect next

After the decision, Reuters reported market pricing of roughly a one-in-three chance of a November rise, with a further rise by February 2027 almost fully priced. BetaShares' David Bassanese now has 4.85% in November as his base case and HSBC's Paul Bloxham expects a rise "most likely in November", while AMP's Shane Oliver expects a hold as the economy cools.

1994–95: the fastest rise, the smallest fall

The RBA lifted the cash rate from 4.75% to 7.50% in four months from August 1994, pre-emptively: underlying inflation was about 2% and unemployment 9.4%. Eight-capital house prices (ABS) slipped just 0.9%, and credit took the hit instead, with housing loan approvals falling "by about a third from their peak in mid 1994" (RBA Bulletin, September 1995). Housing debt was only about 46% of disposable income (June 1994), against 135% today, and the RBA blamed much of the softness on an earlier building boom. Prices regained their peak a month before the first cut in July 1996.

1999–2000: rate rises, rising prices

The RBA raised the cash rate five times between November 1999 and August 2000, from 4.75% to 6.25%. Prices kept rising: established house prices across the eight capitals were 7.4% higher in 2000–01 than in 1999–2000 (ABS), with Melbourne up 10.0% and Sydney 7.0%. The tightening showed up elsewhere. Loan approvals were 20% below their peak by late 2000, and dwelling investment collapsed after the GST started in July 2000, having pulled building work into the first half of the year (RBA, November 2000). By May 2001 the RBA reported "a marked slowing in dwelling price growth", and it had cut three times between February and April 2001, to 5.00%, alongside an extended First Home Owner Grant.

This cycle is the clearest evidence that rate rises don't mechanically produce national price falls. The rises were modest, credit growth slowed without a price fall, and a tax change drove the timing of the housing cycle, which is relevant again in 2026.

2002–08: a long cycle, a Sydney correction and a peak at the final rise

Twelve rises between May 2002 and March 2008 took the cash rate from 4.25% to 7.25%. The early rises targeted what the Board called "the current overheating in the housing market". Sydney peaked in late 2003 and fell 8.4% by early 2006 (ABS RPPI), taking four years to recover, while Perth rose 68% on the resources boom.

The second half of the cycle looks the most like 2026: rises into a commodity and oil surge, with the trimmed mean reaching 4.8% by the September quarter 2008, and banks adding about 55 basis points beyond the cash rate after the 2007 credit crunch. Eight-capital prices (ABS RPPI) peaked in the quarter of the final rise and fell 4.6% to March 2009, or 6.1% across the combined capitals on CoreLogic's measure (March to December 2008). Housing finance fell 25.5%, and in May 2008 APM recorded clearance rates of 44% in Sydney. The fall ended after 425 basis points of cuts and a boosted First Home Owner Grant. Unemployment rose only from 4.0% to 5.9%, so forced selling stayed limited.

2009–10: a normalisation, then an 18-month grind

From the emergency 3.00% of the GFC, seven rises took the cash rate to 4.75% by November 2010, as the first home buyer boost ended and first home buyer lending fell 59%.

Prices peaked 8 to 12 months after the first rise, a month before the final one, then slid 7.4% across the capitals to May 2012 (CoreLogic). Darwin fell 19.7%, Hobart 14.3% and Brisbane 11.7%, while Sydney fell 5.0%. Rents kept rising and unemployment held near 5%, so the adjustment came through turnover, which the RBA put close to its early-1990s low by mid-2012, rather than forced sales. The trough came within months of the first cut in November 2011, and the capital-city index set a new record in September 2013.

2022–23: the biggest rise, and a fall cut short

The fastest tightening in a generation took the cash rate from 0.10% to 4.35% in 18 months. The RBA's April 2022 Financial Stability Review had estimated, with a model it stressed was not a forecast, that a 200 basis point rise could lower real housing prices by around 15% over two years.

CoreLogic's national index fell 9.1% to February 2023 as first published, or 7.5% in today's revised series. Sydney fell 13.8%, Brisbane 11.0% and Melbourne 9.6%, while Adelaide fell 2.3% and Perth 0.9%. Capital-city clearance averaged 56.4% in the September quarter 2022, and new lending fell 33% from its record.

Then prices turned up with 100 to 125 basis points of rises still to come, depending on which trough month is used. The RBA's May 2023 explanation was that "strong underlying fundamentals for housing, such as population and income growth, have offset the effects of the higher cost of credit". Net overseas migration hit a record 518,000 (as first published), unemployment fell to 3.4%, listings sat about 26% below average, and fixed rates delayed the repayment shock. The national index set a record in November 2023; Melbourne remains 6.8% below its March 2022 peak.

What patterns repeat across hiking cycles?

Prices turn before the RBA finishes

Where prices fell, headline indexes peaked about seven months after the first rise in 1994–95, in the quarter of the final rise in 2008, 8 to 12 months in during 2009–10, and at the first rise in 2022 (table above). In 1999–2000 growth slowed without a fall. Buyers price in expected rises, and the turn has come early in recent cycles. The March 2026 peak fits that pattern; it says nothing yet about the depth.

Headline falls are modest; city falls aren't

No headline index has fallen by double digits in a hiking cycle since 1994; the largest national fall on CoreLogic's record before 2022 was the credit-driven 8.4% of 2017–19, when APRA tightened lending. City falls reached 13.8% (Sydney, 2022) to 19.7% (Darwin, 2010–12). In 2026 Sydney is already 7.1% below its February peak, against 6.6% at the same stage of the 2022–23 fall (Cotality; see our Home Value Index tracker).

Troughs often come as cuts become credible, but not always

In 2008 the trough came about six months after the first cut (ABS), and in 2011–12 within one to seven months of it. But in 1994–95 prices recovered a month before the first cut, after 19 months at 7.50%, and in 2023 the market turned while rates were still rising, on migration and a very tight labour market. The pattern is common, not reliable.

Rents rose in every cycle

CPI rent growth rose from 0.7% to 2.9% over 1994–96, peaked at 8.4% in 2008, ran at 4% to 5% in 2010–11 and near 10% a year in 2022–23 (Cotality). In 2026 vacancy is 1.3% and advertised rents are 7.3% higher than a year ago, though flat over the month (SQM; see our August vacancy analysis). Rent growth supports yields but didn't stop prices falling in any cycle.

Lending and auction results fall first

New lending fell by a fifth to a third in every cycle, and where auction data exists (2008, 2022), clearance rates dropped into the 40s and 50s in the weakest months. In 2026, investor lending fell 10.2% in the June quarter (ABS; our lending analysis), and Andrew Wilson's figures, reported by PropertyUpdate, put the national clearance rate at 49.5% for September, against 72.1% a year earlier.

Is 2026 like past cycles? What is the same and what is different

Debt: the same rise hurts more

Household debt is 178% of disposable income and housing debt 135% (RBA, June 2026), a little below 2022 (185% and 139%) but far above 1994 (about 80% and 46%). Scheduled mortgage repayments were already 9.42% of disposable income in the March quarter 2026 (RBA Table E13), close to the June 2024 record of about 10.1%, before the September rise. As Tim Lawless of Cotality put it on Tuesday: "Household indebtedness is much more significant now than it was back in 2011, so households feel the pain of interest rate hikes much more acutely."

Source: RBA Table E2 (June quarter of each year; 1994 value June 1994).

No fixed-rate delay this time

In 2022–23 fixed loans spread the shock over three years: about 880,000 expired during 2023, and outstanding mortgage rates rose only about 75% as much as the cash rate (RBA). In 2025 fewer than 5% of outstanding home loans were fixed, a record low (RBA Bulletin, May 2026), so nearly every borrower now reprices within weeks of each rise.

The 2023 support conditions are materially weaker

Migration and jobs carried the 2023 recovery. Today population growth is 1.4% (+392,700 in the year to March 2026) and net overseas migration 292,100, against a 2.5% growth peak and about 556,000 NOM in the year to September 2023 (ABS). Unemployment is 4.6% and rising, from a 3.4% low in October 2022. In 2008 unemployment was near 4% and in 2010 near 5%. A labour market that keeps loosening is the condition most likely to turn a 2010-style grind into something deeper.

Tax and lending rules that no earlier cycle had

Under the Treasury Laws Amendment (Tax Reform No. 1) Act 2026 (Royal Assent 26 June 2026), net rental losses on established dwellings acquired after 7.30pm (AEST) on 12 May 2026 are quarantined from the 2027–28 income year: they offset only residential property income and capital gains, and the rest is carried forward. New dwellings are exempt. Separately, the CGT discount changes from 1 July 2027: gains accrued to 30 June 2027 keep the 50% discount through a deemed sale and reacquisition (with the tax deferred until you actually sell), later gains on established property get cost-base indexation with a 30% minimum tax, and eligible new residential dwellings keep the 50% discount, with an option to use indexation. Our CGT transition guide covers the detail. The RBA's August Statement on Monetary Policy cited "recently announced tax changes", alongside higher rates, in the fall in investor lending.

APRA's rules are also tighter than in any earlier cycle. Lenders assess new loans at the product rate plus 3 percentage points, and since 1 February 2026 no more than 20% of each lender's new owner-occupier or investor lending can be at a debt-to-income ratio of six or more (new builds and bridging loans are exempt). The cap isn't binding yet, with 8.9% of new investor lending at that level in the June quarter (APRA), but it limits how fast credit can re-accelerate.

What cushions 2026

Three things argue against a forced-sale correction. Offset balances are 13.3% of housing credit (APRA), and the RBA estimates the median borrower in even the lowest income quartile could meet almost a year of repayments from offset and redraw. Arrears remain near pre-pandemic levels. Supply is also scarce: about 173,500 homes were completed in the year to March 2026, the same number as in 1994 for a population 56% larger, or 6.2 per 1,000 residents against 9.7. Bullock warned the downturn "may make it uneconomic for developers to build". Scarce supply supports rents and the medium-term floor, even if it doesn't stop near-term falls.

Which past cycle is the closest match, and what does it imply for prices?

The case for 2008

In both 2008 and 2026 the RBA raised rates late in the cycle into an energy shock, with underlying inflation well above target (4.8% then, 3.6% now). In 2008 the floor came only after the RBA cut hard in a global financial crisis. Without an external shock, the path to cuts in 2026 runs through inflation falling, which takes longer.

The case for 2010–12

The 2010–12 decline had tight rentals, rising rents, unemployment near 5% and buyers stepping back rather than sellers being forced out. It fell 7.4% across the capitals over 19 months, with the biggest falls in the markets that had run hardest. The 2026 market shows the same signs: capital-city days on market are 37 against 25 a year ago and the median capital-city vendor discount is 4.2%, while national total listings are up 18.1% and new listings down 3.1% (Cotality, August).

Three scenarios

These ranges are scenario constructs based on the historical episodes above and current published forecasts; they are not estimates from a formal econometric model.

Source: our analysis, informed by the historical record above and published forecasts: Westpac Housing Pulse, September 2026 (national −7.3% peak to trough; five major capitals −6% in calendar 2026); CBA, 1 September 2026 (national −9% peak to trough, Sydney −13%, Melbourne −12%, trough in 2027); ANZ Research, August 2026 (capital cities −10.6% peak to trough into 2027).

National values are already down 3.6%, so even the first scenario implies a further fall of roughly 2.5% to 5.5% from here.

What would prove this view wrong

Our 2010–12-style reading would be wrong if any of these appear over the next two to three months:

• Unemployment falls back toward 4% instead of rising, removing the main risk of a deeper fall.
• Migration re-accelerates, with quarterly net overseas migration back near 2023 levels.
• Listings drop sharply and clearance rates return above 60% while rates are on hold, the 2023 pattern.
• Markets start pricing rate cuts for the first half of 2027, which history suggests would bring the floor forward.
• On the downside, unemployment above 5% with sticky inflation would point to the higher-for-longer scenario instead.

Where have investors held up best when rates rise?

Interest cover in selected markets

Source: suburbs from our Top 10 Suburbs, September 2026 (Cotality via Your Investment Property; SQM postcode vacancy); cities from Cotality's August 2026 index and September chart pack, and SQM. Interest on an 80% loan at an illustrative 6.65% and 6.90%; gross rent before costs, tax and vacancy.

Illustrative: 80% loan, gross rent before costs. Source: our calculation from Cotality, SQM and our Top 10 Suburbs data.

Worked example: two properties, four rate rises

Take two illustrative investment properties bought with an 80% interest-only loan. Property A is a $750,000 unit at a 3.3% gross yield, similar to the Sydney average. Property B is a $400,000 regional unit at a 6.0% yield, similar to several markets in our Top 10. Holding costs other than interest are $6,000 a year for A and $5,000 for B.

Source: our calculations. Rent: A $24,750, B $24,000 a year. Interest: 80% loan × rate. Before tax, depreciation and vacancy.

Each 25 basis points costs A $1,500 a year and B $800; the four 2026 rises turned B from positive to negative.

If either property were an established dwelling bought after 12 May 2026, the loss would be deductible against wages in 2026–27 but quarantined from the 2027–28 income year, so A's $21,150 loss would be carried forward rather than reducing that year's tax bill.

The risk in high-yield markets

High-yield markets have fallen hard before. In 2010–12 Darwin fell 19.7% and Hobart 14.3%, because smaller, less liquid markets tied to a single industry or to lifestyle demand can move sharply. Several 2026 high-yield markets have run hard (Manunda units +28% and Geraldton units +42% over the year), so check vacancy, supply pipelines and employment concentration as well as the rent.

What should property investors do after the September rate hike?

Profile 1: The existing investor with negative cash flow

Situation: two investment properties in Melbourne and Sydney, $1.2 million of variable debt, both negatively geared, bought before 2026, and about $450 a week negative after four rises.

Reasoning: each further 25 basis points adds about $58 a week. Prices fell for 9 to 19 months in past cycles, so selling now risks crystallising a loss near the bottom. Both properties were bought before 12 May 2026, so their negative gearing is grandfathered while held.

Strategy: check the offset balance against six months of the shortfall and ask the lender for a rate review. If cash flow is unsustainable, sell the weaker asset rather than both, after tax advice. Our mortgage stress guide covers restructuring options.

Profile 2: The growth buyer waiting for the bottom

Situation: $250,000 in savings, pre-approved, targeting a Sydney house to hold for 15 years.

Reasoning: in 2008 and 2011 the trough came after the first cut, and in 2010–12 Sydney fell less than the other large capitals and regained its peak first, by the end of 2012 (ABS). A 4% to 8% discount to recent sales can be worth more than trying to time the exact bottom.

Strategy: buy only when the holding cost works at a 4.85% cash rate without relying on growth, and price offers on stock listed 45 days or more off the last 90 days of sales.

Profile 3: The yield-focused buyer with finance ready

Situation: $120,000 deposit, $150,000 income, looking at $400,000 to $550,000 regional or smaller-capital stock.

Reasoning: tight, high-yield markets fell least in 2022–23, and rent that covers interest reduces exposure to each rise. The risk is buying after a local boom.

Strategy: use the interest-cover test (rent at least 1.1 times interest at 6.90%), check vacancy below 1%, and avoid single-industry towns. New builds avoid the negative gearing quarantine but still need to stack up on price. Our Top 10 Suburbs for September screens for these criteria.

Profile 4: The grandfathered holder thinking about selling

Situation: owns an established unit bought in 2019, negatively geared, and wants to reduce debt.

Reasoning: selling gives up grandfathered negative gearing, which the next buyer can't get. The CGT change doesn't force a sale either: gains built up to 30 June 2027 keep the 50% discount, and later growth gets indexation with a 30% minimum tax. Selling while the median capital-city vendor discount is 4.2% means accepting a weak price.

Strategy: model hold versus sell with your accountant, including how the 2027 CGT transition applies to your gain. If you do sell, launch early in a campaign cycle and price off recent comparable sales rather than the peak.

Profile 5: The first-time investor with an older pre-approval

Situation: pre-approved in August for a $600,000 purchase at a 6.40% rate.

Reasoning: the lender will reassess at the new rate. Holding income and expenses fixed, the rise in the assessment rate from 9.40% to 9.65% lowers maximum borrowing by about 2.1% on a 30-year loan (our calculation), or around $10,000 on an 80% loan.

Strategy: ask the lender to reconfirm the approval at the new rate before bidding, leave headroom rather than borrowing to the maximum, and use our borrowing capacity calculator to test a further rise. Our guide to how much you can borrow explains how lenders assess investors.

Decision framework

• Buying now is better when: your finance is settled with headroom, the rent covers most of the interest at 6.90%, you're buying at a discount to recent sales, and you plan to hold for more than seven years.
• Waiting is better when: the purchase only works if prices rise soon, you'd be borrowing close to your maximum, or your job or income is exposed to a slowing economy.
• Selling is better when: holding costs are unsustainable after a rent review, you wouldn't give up grandfathered tax treatment, or you're buying and selling in the same falling market.

Risks and how to manage them

The Bottom Line

The RBA's fourth rise of 2026 takes the cash rate to 4.60%, and the Board hasn't ruled out more. The five hiking cycles since 1994 suggest a broad path rather than a rule: prices usually turn early, headline falls have stayed in single digits while some cities fell by double digits, and troughs have often come as rate cuts became credible. In 1999–2000 prices didn't fall at all. On that record, national values are likely to fall further from today's 3.6% decline, and published forecasts of a 7.3% (Westpac) to 9% (CBA) national fall sit within the historical range.

The conditions that shortened the 2022–23 fall are materially weaker. Migration is slowing, unemployment is rising, almost no loans are fixed, and new purchases of established homes face a negative gearing quarantine from 2027–28. Record offset buffers and scarce supply make a forced-sale collapse unlikely, but a rebound would still need rate cuts in sight.

The practical lessons are to stress-test at 4.85%, favour rent that covers the interest, negotiate while discounts are wide, and plan for a recovery measured in years. The next tests are the September-quarter CPI on 28 October and the RBA on 3 November. Our September preview and Cotality August 2026 analysis have the detail.
