Australian banks are engaged in an intense competition to attract home loan customers, leading to significant changes in the mortgage market. This "mortgage war" has resulted in lower interest rates and more favorable terms for borrowers, but it also raises questions about the sustainability of these practices and their long-term impact on the housing market.
In recent months, several major banks have reduced their variable mortgage rates, even before the Reserve Bank of Australia (RBA) adjusted the official cash rate. For instance, 18 banks cut their variable rates within days of a major lender's surprise double cut, despite the RBA cash rate holding steady at 4.35%. This aggressive pricing strategy is driven by competition for market share, as banks aim to attract new customers and retain existing ones.
The average new home loan in Australia now stands at $734,881, with an average interest rate of 5.90% per annum. This translates to monthly repayments of approximately $4,359 over a 30-year term. The total value of new home loans issued between January and March 2026 was $103 billion, indicating a robust demand for housing finance.
However, this aggressive rate-cutting has led to a decline in the net interest margins of banks, raising concerns about the sustainability of such practices. The increased competition has also resulted in a shift in market share among the major banks. For example, Westpac has seen its share of the mortgage market decrease by 3.2 percentage points since March 2019, while the Commonwealth Bank of Australia (CBA) has increased its share over the same period.
Looking ahead, the future of this mortgage war remains uncertain. While borrowers currently benefit from lower rates, the long-term effects on the housing market and the banking sector are yet to be fully realized. Potential borrowers should stay informed about market trends and consider their financial situation carefully before making decisions.
