Australian Housing Market Faces Prolonged Downturn Amidst Rising Interest Rates

Australia's housing market is poised for a more significant and extended downturn than previously experienced, as rising interest rates and decreasing borrowing capacity impact homeowners and potential buyers. The Reserve Bank of Australia recently increased the cash rate to 4.6 percent, the highest in nearly 15 years and the fourth such hike this year. This has led to a more than $450 increase in monthly mortgage repayments for the average Australian homeowner since the beginning of 2026.

Reduced Borrowing Power

Housing data firm Cotality reports that home buyers now have $90,000 less borrowing capacity compared to February. Tim Lawless, head researcher at Cotality, noted that the current economic climate is distinct from past downturns. He stated that higher household indebtedness means individuals feel the impact of interest rate hikes more acutely. In 2011, when interest rates were last at this level, homeowners spent just over one-third of their income on mortgage servicing; today, that figure exceeds half, exacerbating the downturn.

Broadening Price Declines

National dwelling values have already declined by 3.1 percent in the three months leading up to the end of August. The removal of tax concessions for investors in the May budget has also contributed to the slowdown. Lawless anticipates that successive rate increases will cause price falls to become more widespread across the property market.

Reserve Bank governor Michele Bullock indicated that lower house prices are a natural consequence of interest rates working to control inflation, affecting household wealth and potentially influencing consumption. However, the rising cost of construction, driven by material and fuel prices, could lead to more expensive housing in the long term, even as affordability temporarily improves due to price drops. This could reduce the supply of new homes as construction becomes less viable for builders.
