Australia: RBA Delivers Fourth Hike to 4.60% Into a Six-Month Housing Downturn — the Question Is Whether Forced Selling Follows

The RBA's September 29 decision (watch fired, resolved) landed exactly as the Reuters poll predicted: +25bp to 4.60%, unanimous (9-0), the fourth hike of 2026 (Feb, Mar, May, Sep) and the highest cash rate since 2011. The statement is remarkable for how explicitly it acknowledges it is hiking into a falling housing market: "housing prices have fallen in most capital cities and new housing loans have declined noticeably", and later: "there are uncertainties about the economic effects of the downturn in the housing market." The easing-off language investors look for isn't there — the Board kept the door wide open: "The Board will continue to do what it considers necessary to bring inflation sustainably back to target, including increasing the cash rate target further if needed."

The September data: correction broadening and accelerating

Cotality's (ex-CoreLogic) national Home Value Index, released October 1, fell -1.1% in September — the sixth straight monthly fall — leaving values 5.2% below the March 2026 record high. Sydney is now 8.6% below its February peak, "marginally deeper than the equivalent stage of the 2022-23 downturn". Brisbane fell most among capitals (-1.5%), and 97% of capital-city suburbs were down in value over the three months to September. The volume signals are the contagion-relevant part: home sales over the past three months ran 19.1% below a year ago (Brisbane -27.2%, Sydney -26.5%), while total advertised inventory is 23.1% higher and median days-to-sell blew out to 39 from 23. Cotality's Tim Lawless: "Despite fewer new listings entering the market, inventory levels have risen sharply because the rate of sale has fallen even faster. Capital city homes are now taking a median of 39 days to sell compared with 23 days a year ago." (Cotality HVI, October 1, 2026)

realestate.com.au's own index, covering the same month, shows the same direction but a much milder magnitude: -0.2% m/m, 3.3% below peak, annual growth collapsing from 1.8% to 0.1% — with the sharpest falls now in the previously strongest markets (three-month annualised declines: Adelaide -8.6%, Brisbane -7.9%, Perth -7.4%). Its key judgment on the brief's forced-selling question: "Importantly, softer conditions are not currently being accompanied by widespread forced selling... employment remains resilient and most existing homeowners have substantial equity buffers." It counts 100bp of cumulative 2026 tightening hitting borrowing capacity with lags still to come. (realestate.com.au Home Price Report, September 2026)

Index divergence flag (for the brief's data-quality theme): for the same month, Cotality says national values are 5.2% off peak (-1.1% m/m); realestate.com.au says 3.3% off peak (-0.2% m/m). Both agree on direction (sixth straight fall, Darwin the only riser) but the severity gap — a 1.9pp difference in peak-to-date drawdown — is material for anyone mapping drawdown severity across countries. Cotality is the index institutions and APRA-adjacent work typically cite.

What it means

Australia is the first tracked market where the rate shock has been fully transmitted — variable-rate-heavy mortgages mean the 100bp of 2026 hikes is already in household budgets¹, and the RBA is still hiking with a November follow-up projected by CBA. The preconditions for the forced-selling phase the brief watches for are assembling (sales volumes falling ~5x faster than prices, inventory +23%, days-to-sell +70%), but both index providers say forced selling hasn't started — employment and equity buffers are holding. Watch the November 3 RBA meeting and the October HVI (due ~Nov 1); if a fifth hike lands into a seventh straight monthly fall, the "slowdown → bust" call for Australia becomes live.
