As of March 2026, Macquarie's mortgage book reached $173.7 billion, accounting for 7% of the total market share among authorised deposit-taking institutions (ADIs). In contrast, the combined market share of the big four banks has decreased from 79% to 73% over the past seven years, indicating a gradual shift in the competitive landscape.

Macquarie's growth can be attributed to its competitive loan offerings and efficient digital platforms, appealing to a broad range of borrowers. This expansion reflects a broader trend of increased competition in the mortgage sector, providing consumers with more options and potentially better terms.

For prospective borrowers, this development underscores the importance of exploring various lenders beyond the traditional big four. Comparing loan products from institutions like Macquarie can lead to more favourable interest rates and loan conditions.

In conclusion, Macquarie Bank's substantial growth in the mortgage market signifies a changing dynamic in Australia's lending landscape. Borrowers are encouraged to consider a diverse range of lenders to secure the best possible mortgage deals.
