WARNING: Australia’s Inflation Spike Could Hit House Prices (Prepare Now)

Summary

The presenter argues that Australian housing could remain under pressure even if the RBA’s next rate rise is its last. High borrowing costs continue to reduce buyers’ borrowing capacity and strain household cash flow. He cautions that this is a cyclical, uncertain outlook—not a prediction that every area will fall equally.

Inflation and interest rates

• ABS figures cited show annual headline inflation rose to 4.3% in September, from 4.0% in August, compared with economists’ forecast of 4.2%.
• The RBA’s preferred trimmed-mean inflation measure was 3.6% monthly, up from a revised 3.5%, and rose 1.0% in the September quarter, above the RBA’s 0.8% forecast. Both headline and core inflation were above the RBA’s 2–3% target.
• Housing costs were described as the biggest contributor to inflation, with fuel second. The presenter attributed pressure on oil prices to Middle East tensions. He noted that interest-rate rises cannot directly lower oil prices, but the RBA can curb domestic spending by making credit more expensive.
• The RBA had raised the cash rate from 4.35% to 4.60% on September 29, described as the fourth increase of the year. The market was pricing an 80–90% chance of another 0.25-percentage-point increase on November 3, taking the rate to 4.85%. This would be the fifth increase of the year; the presenter said the year’s rises total 1.25 percentage points.
• The RBA’s mandate is inflation and employment, not supporting house prices. The presenter said it may keep tightening despite falling property prices if inflation expectations remain a concern.

Borrowing power and housing-market effects

• A Canstar estimate cited by the presenter suggests each 0.25-percentage-point rise adds about A$114 per month to repayments on a A$750,000 variable-rate loan. He estimates roughly A$450 more per month after four rises and A$570 after five—around A$7,000 a year after five.
• A PIIPA estimate cited suggests each 0.25-percentage-point rise reduces an average dual-income household’s borrowing capacity by about A$18,000. A household approved for A$800,000 earlier in the year could have roughly A$70,000 less capacity after four increases and A$90,000 less after five.
• The presenter describes the resulting dynamic as lower buyer bids and a standoff with sellers anchored to earlier prices. Fixed-rate borrowers may also face repayment increases when their loans roll onto higher rates.
• CoreLogic’s Home Value Index was cited as showing national values down 1.1% in September, the sixth consecutive monthly decline, and 5.2% below the March record. Median time on market was 39 days, compared with 23 days a year earlier.
• Roy Morgan data was cited for mortgage stress at an 18-year high, after rising for six consecutive months.
• As an anecdote, the presenter described a Palm Beach listing that had returned to market at a price roughly 10–15% below its earlier asking price.
• He noted that regional values were still up 5.6% over the year and that Australian national prices remained about 50% above early 2020. He also cited the RBA’s October Financial Stability Review as finding fewer than 1% of borrowers in negative equity.

Cycle framework and overseas comparison

• The presenter uses the 18-year real-estate-cycle theory, associated with Fred Harrison and Phil Anderson: approximately 14 years of growth followed by four years of decline. Counting from a 2012 low, he places a possible peak around 2026.
• He describes the cycle’s late “winner’s curse” phase as especially risky for highly leveraged buyers, investors relying on negative gearing or rental top-ups, and owners who bought expecting rate cuts.
• As a comparison—not a claim that Australia will repeat the same outcome—he cites BNZ analysis using the REINZ House Price Index, which describes a New Zealand decline of roughly 16% or more from late 2021 into 2023. The transcript also mentions estimates of about 18.5–20% for the overall national average.

Suggested actions and indicators

• Borrowers: Know repayment levels and buffers, and stress-test budgets at rates 0.25 and 0.50 percentage points higher. Contact a lender’s hardship team early if repayments are becoming difficult.
• Buyers: Refresh loan pre-approval after the November decision. Base offers on comparable sold prices and time on market rather than asking prices.
• Property investors: Test cash flow at current rates plus another rise, use realistic rent assumptions, and decide how long they can sustain any monthly shortfall.
• Signals to monitor:
  • Trimmed-mean inflation moving back toward 2–3%.
  • New housing lending picking up for several months.
  • Time on market falling from 39 days.

The presenter says improvement across all three would warrant reassessing the outlook.

• Even if rates stop rising, he cautions that pressure can persist until rates fall, credit loosens, and buyers regain financing capacity.
