The latest mortgage figures have shown the country’s largest housing lenders still expanding their books, with CBA and Macquarie at the front of the pack.
The Australian Prudential Regulation Authority’s (APRA) Monthly Authorised Deposit‑taking Institution Statistics for June 2026 has revealed that the country’s top‑10 banks substantially lifted their combined housing balances, with the Commonwealth Bank of Australia (CBA) adding the most dollars to its book and Macquarie posting the strongest percentage growth.
Across the top 10 ADIs, total housing loans – combining owner‑occupier and investor balances – continued to grow in June.
CBA, Westpac, National Australia Bank (NAB), Australia and New Zealand Banking Group (ANZ), Macquarie Bank, ING Bank, Bendigo Bank, and HSBC Bank all expanded their books, while Suncorp Bank and the Bank of Queensland (BOQ) recorded net declines.
CBA remains the clear volume leader, seen in its total housing loan book climbing to $635.5 billion, up $5 billion in the month (0.79 per cent).
Owner‑occupier balances rose by $3.47 billion to $413.4 billion, while investor loans increased by $1.54 billion to $222.1 billion, with the figures confirming CBA’s position as a lender still growing at close to 0.8 per cent a month despite a cooler inquiry environment.
Macquarie Bank again posted the strongest percentage growth among the top 10, a pattern that has been evident in APRA’s February, March, and April releases.
Its June housing book jumped $3.39 billion (1.88 per cent) to $183.7 billion, with owner‑occupier and investor balances each rising by 1.88 per cent – to $112.3 billion and $71.4 billion, respectively.
APRA’s earlier data showed Macquarie grew its book by 2.03 per cent in April and 2.1 per cent in March, underpinning year‑on‑year expansion above 25 per cent.
Among the other major banks, Westpac’s total housing book increased by $2.78 billion (0.54 per cent) to $517.6 billion, NAB rose $1.77 billion (0.50 per cent) to $351.5 billion, and ANZ lifted $3.12 billion (0.95 per cent) to $330.9 billion.
Investor tilt persists despite macroprudential clamp
The June statistics highlighted how strongly investor portfolios are driving growth at several institutions.
ANZ’s investor book expanded by $1.71 billion in the month, a 1.53 per cent rise compared with 0.65 per cent growth in owner‑occupier loans.
NAB’s investor balances jumped 0.93 per cent, more than triple its 0.30 per cent owner‑occupier growth.
Meanwhile, ING’s investor portfolio grew 1.45 per cent, outpacing 0.54 per cent for owner‑occupiers, while Macquarie’s investor and owner‑occupier books grew in lockstep at 1.88 per cent.
This investor tilt is occurring under APRA’s new macroprudential rules, which cap the share of new lending with debt‑to‑income ratios of six or above at 20 per cent of flows for each ADI.
Mid‑tiers split: ING and Bendigo edge higher as Suncorp and BOQ shrink
Among the non‑major players, ING’s total housing loans rose to $74.2 billion, up $0.56 billion (0.76 per cent).
Its owner‑occupier book reached $55.4 billion after a $0.30 billion increase (0.54 per cent), while investor balances climbed to $18.8 billion, up $0.27 billion (1.45 per cent).
That performance builds on earlier APRA releases that have consistently shown ING growing at roughly double the majors’ pace.
Bendigo and Adelaide Bank delivered a more subdued result, with its total housing book inching up to $64.5 billion, a $0.11 billion (0.16 per cent) rise, with owner‑occupier balances effectively flat at $49.5 billion (+$0.03 billion; 0.06 per cent) and investor loans at $15.0 billion (+$0.08 billion; 0.51 per cent).
By contrast, Suncorp Bank and BOQ again went backwards.
Suncorp’s total housing book fell to $57.0 billion, down $0.13 billion (-0.23 per cent).
Owner‑occupier balances slipped to $39.8 billion (-$0.07 billion; -0.18 per cent), while investor loans dropped to $17.2 billion (-$0.06 billion; -0.35 per cent).
BOQ’s total book declined to $51.2 billion, a $0.22 billion (-0.42 per cent) contraction, driven by a $0.22 billion (-0.63 per cent) reversal in owner‑occupier loans to $35.6 billion, partially offset by a marginal $0.01 billion (0.04 per cent) uptick in investor balances at $15.6 billion.
APRA’s February and April statistics showed Suncorp and BOQ significantly shrinking, reflecting strategic retrenchment ahead of ANZ’s acquisition of Suncorp and BOQ’s tighter risk and distribution stance.
HSBC edges higher as future transfer looms
HSBC Australia’s housing loan book rose to $35.1 billion in June, up $0.15 billion (0.44 per cent).
Owner‑occupier balances reached $24.4 billion (+$0.13 billion; 0.52 per cent), and investor loans climbed to $10.7 billion (+$0.03 billion; 0.24 per cent).
The June uptick comes ahead of HSBC’s agreed sale of its $36 billion Australian home and personal loan portfolio to Blackstone, announced at the end of July, which will see Pepper Money take on loan management for the book.
Reading June’s numbers in context
Taken together, APRA’s June 2026 MADIS release points to a mortgage market still growing in aggregate, but increasingly defined by two-speed expansion.
The big four continue to add volume at around half to 1 per cent per month, with CBA leading in absolute dollar growth and ANZ strongest on percentage terms among the majors.
Macquarie and ING remain the standout challengers, repeatedly posting growth rates several times higher than their larger rivals, while Suncorp and BOQ continue to cede ground.
