NAB is the fourth big bank to report home loan applications diving

Profit holds, but the mortgage desk is quiet

Cash earnings for the three months ended 30 June 2026 rose 2 per cent to $1.83 billion, with statutory net profit coming in just below at $1.81 billion.^[1] The gap between those two figures is thin, which tells you there were no large one-off items distorting the result either way.

Behind the headline sits a home lending market that has moved sharply in the wrong direction. NAB is far from alone in feeling it.

The mortgage desk goes quiet

Home loan applications fell 15 per cent in the June quarter compared with the March quarter, a drop the bank attributed directly to the federal budget's investor tax changes.^[1] A 15 per cent quarterly fall in applications means fewer customers entering the pipeline, which flows through to settlement volumes and, eventually, net interest income.

Group Chief Executive Officer Andrew Irvine was direct about the cause, saying business credit growth had remained strong but that the Australian home lending market softened in the third quarter, with applications down 15 per cent compared with the second quarter.^[1] The commercial book is holding; the residential side has stalled.

Irvine broadened the frame when describing the environment facing customers. "The combined impacts of the Middle East conflict, higher domestic interest rates and recent tax changes in the federal budget are creating challenges and uncertainties for our customers," he said.^[1] Stacking geopolitical risk alongside a domestic policy shift and an elevated rate environment is a signal that NAB does not expect a quick rebound in housing demand.

The budget's fingerprints are across the whole sector

NAB's 15 per cent drop sits inside a broader pattern that has emerged as the Big Four have reported through August. The federal budget's changes to negative gearing and capital gains tax, taking effect from the 2026-27 income year, have rewired the calculus for property investors at precisely the moment banks need volume growth to offset margin pressure.^[1]

Commonwealth Bank disclosed a 28 per cent fall in investor home loan applications over the same period, a steeper decline that reflects both CBA's larger retail mortgage footprint and the concentration of investor borrowers on its books. Westpac reported a similar post-budget run rate, and the synchronised pullback across four institutions confirms this is a policy-driven demand shock rather than a bank-specific execution problem.

For NAB, the timing adds complexity. NAB has spent the past two years deliberately growing its retail mortgage share after ceding ground to CBA and Westpac, and a broad investor withdrawal tests whether that rebuilt pipeline is deep enough to absorb the drop in one borrower segment without losing overall momentum.

Capital: the buffer that keeps options open

NAB's Common Equity Tier 1 ratio sat at 11.93 per cent as at 30 June 2026, according to its Pillar 3 disclosure.^[2] That number matters for two reasons: it places NAB well above APRA's minimum capital buffers, and a thick capital cushion gives management room to price competitively in mortgages without triggering concerns about capital adequacy.

At 11.93 per cent, NAB can absorb a meaningful deterioration in credit quality before it would need to raise capital or cut dividends.^[2] In an environment where Irvine is flagging geopolitical and domestic rate uncertainty in the same breath, that cushion is the reason NAB can still compete for mortgage business even as application volumes fall.

What this means for borrowers

The immediate read for anyone with a mortgage or a property investment on the drawing board is that the banks are not withdrawing from the market. NAB's capital position and Irvine's explicit statement that business credit remains healthy suggest the institution is open for lending; what has changed is the mix of who is applying.

Investor demand, particularly for new purchases structured around negative gearing, has pulled back sharply across the sector.^[1] Owner-occupiers and refinancers are less directly exposed to the budget's CGT and negative gearing changes, so that segment is likely to stay more active. For those borrowers, a bank sitting on a CET1 ratio of 11.93 per cent and watching competitor volumes fall has every incentive to sharpen pricing and cut approval times to win share.^[2]

The harder question is whether the investor pullback deepens. If the 15 per cent drop in applications does not stabilise by the September quarter, it will begin to compress NAB's net interest income in a way the current profit line does not yet reflect, and Irvine's comments suggest management is watching the same variables the rest of the market is: the direction of domestic rates and whether the budget-driven repricing of property investment proves temporary or structural. NAB's full half-year result will provide the next detailed look at margins, credit quality and cost trends.^[1]
