Australia’s banking sector has hit a historic milestone, with total outstanding home loans reaching an unprecedented $2.30 trillion in March 2025, according to the latest statistics from the Australian Prudential Regulation Authority (APRA).
This equated to a monthly increase of 0.44 per cent across owner-occupier and investor loan books of Australian authorised deposit-taking institutions (ADIs).
APRA’s latest statistics showed that banks held $1.56 trillion in owner-occupier loans, while investment loans accounted for $737 billion of the $2.3 trillion total.
Mortgage lending rose by approximately $10 billion month on month, pushing annual growth to 5.55 per cent or $120 billion more than the previous year.
This coincided with recent data from PEXA’s latest Mortgage Insights report for the March 2025 quarter, which found annual value for new loans increased by 7.6 per cent year on year and 8.2 per cent for residential only.
However, the aggregate national value of new loans fell by 21.7 per cent from the previous quarter, down to $80.2 billion, the majority of which ($73.5 billion) was for residential property, which fell by 20.6 per cent.
A similar trend was seen in the total volume of new loans that rose 4.4 per cent year on year but fell 18.9 per cent from the December 2024 quarter.
Big 4 record strong yearly growth
The Commonwealth Bank of Australia (CBA) held on to its market share lead with the largest mortgage portfolio of the big four banks, totalling $583 billion.
This included $385.6 billion in loans to owner-occupiers and $197.7 billion for investment properties. CBA’s home loan book has grown 6.13 per cent over the 12-month period to March 2025.
Westpac – still in second place – finished March with $483 billion across its owner-occupier and investor book, an increase of 3.20 per cent year on year. Its lending is split between $320 billion in owner-occupier loans and $162 billion in investment loans.
NAB came in third, with a total loan book of $328 billion as of March 2025. That included $218 billion in owner-occupier loans and $110 billion in investment lending, reflecting annual growth of 3.18 per cent.
ANZ recorded a mortgage book worth $312 billion, with $208 billion in owner-occupier loans and $103 billion in investment loans. ANZ’s total mortgage lending grew by 5.88 per cent compared to March 2024.
