Australian Banks Face Growing Risks as Credit Growth Slows and Property Prices Weaken
Key Takeaways
- •Australian banks face slowing credit growth and falling mortgage demand, which directly affects their profitability since lending is a major earnings source.
- •The major banks — Commonwealth Bank, Westpac, NAB and ANZ — dominate domestic lending, with residential mortgages forming a substantial share of their loan books.
- •Continued property price declines could leave more recent buyers in negative equity, amplified by Australian households' high debt-to-income levels.
- •Higher interest rates, tax policy changes, and uncertainty are causing buyers and investors, including experienced ones, to delay property purchases.
- •Key indicators to watch include housing credit growth data, auction clearance rates, and property price indices, as falling loan applications could slow bank earnings growth and lower valuations.

On this week's episode of Money & Investing, Mitch Olarenshaw and Andrew discuss the mounting risks confronting Australian banks, examining how slowing credit growth, falling mortgage demand and weakening property prices could carry broader consequences for borrowers, investors and the wider economy.
Australian banks are experiencing a slowdown in credit growth, with fewer people applying for mortgages and overall borrowing activity beginning to weaken. Lending is one of the banks' largest sources of earnings, so a decline in new loan volumes directly affects their profitability. Australia's major banks — the Commonwealth Bank, Westpac, NAB and ANZ — dominate the domestic lending market, and residential mortgages make up a substantial share of their loan books, making them particularly sensitive to shifts in housing credit demand.
A modest fall in property prices may not appear significant on its own, but it can create larger problems for recent buyers. Should property values continue to decline, more Australians could find themselves in negative equity — a situation in which the outstanding loan is worth more than the home securing it. Australian households carry among the highest debt-to-income levels in the developed world, a long-noted feature of the economy that amplifies the impact of falling home values on household balance sheets.
Higher interest rates, changing tax policies and growing uncertainty are leading many buyers and investors to postpone property purchases. Even experienced property investors are choosing to stay on the sidelines rather than transact in the current environment.
For borrowers carrying large mortgages, rising repayment costs increase the likelihood of loan arrears and financial stress. The longer interest rates remain elevated, the greater the pressure on household budgets. Banks typically hold provisions against expected loan losses, so rising arrears would flow through to their reported earnings as well.
If loan applications continue to fall, Australian banks could face slower earnings growth and lower valuations. Andrew and Mitch outline the key economic signals investors should be watching over the coming months, including housing credit growth data, auction clearance rates and property price indices — all of which provide timely readings on the trajectory the discussion centres on.
