Borrowing Capacity Shrinks as RBA Rate Hike Looms

The Reserve Bank of Australia is set to meet this week, with financial markets and major banks anticipating a fifth interest rate hike for 2026. If confirmed, this would push the official cash rate to its highest level in 15 years, further increasing the cost of mortgage repayments for Australian households.

The cumulative impact of the four rate increases already implemented this year has been substantial. Research indicates that the borrowing capacity of a median-income household has been reduced by approximately $90,000, or 9 per cent, since February.

For existing homeowners, the prospect of another rate rise is heightening concerns regarding mortgage stress. Many households are already managing tighter budgets, and further increases could push the level of mortgage stress to its highest point since 2008, according to recent economic analysis.

Prospective buyers are also feeling the pressure, as reduced purchasing power forces many to reconsider their property search criteria. With economists suggesting that interest rate cuts are unlikely until at least the second half of 2027, the current high-interest environment is expected to remain a major constraint on market demand.
