Credit Surges as Collateral Falls and Real Wages Slip

Australia's housing credit book reached A$2,568 billion as the RBA lifted rates to a 16-year high,¹ while the dwelling stock backing those loans recorded its first quarterly fall since 2022.²

Updated 4 October 2026: source links that no longer worked (an RBA lending page, the ASX rate indicator and an OECD data page) now open the current pages. Correction, 4 October 2026: the timeline title said the rate reversal took 18 months; from the August 2025 low to September 2026 it took just over a year. Source links now open the specific releases cited. Correction, 4 October 2026: an earlier version quoted ASX futures pricing for a 6 October RBA meeting, which is not scheduled; our rate indicator used an outdated meeting calendar. Pricing for the next meeting, on 3 November, as at 4 October: 19.3 per cent chance of a hike, 80.7 per cent hold, no chance of a cut (previously reported as no chance of a hike). Related figures and wording have been corrected; the findings are unchanged. Correction, 3 October 2026: chart titles and a few statements now describe only what the data show over the period shown (for example, where one measure rose while another fell, both now hold over the same period). The findings are unchanged.

Australia's housing credit book reached A$2,568 billion³ as the total value of the nation's residential dwellings fell A$34 billion in the June quarter.²

Three forces have converged: a credit book at a record high and still growing at 7.3 per cent a year, collateral that has begun to shrink, and real wages that turned negative in Q2 2026 as wage growth of 3.2 per cent⁵ trailed consumer price inflation of 3.94 per cent.⁵

Markets lean towards a hold: ASX futures price a 19.3 per cent chance of a hike and no chance of a cut at the 3 November meeting.⁷

The 12-month housing credit growth rate reached 7.3 per cent in August 2026,³ up from 6.1 per cent a year earlier and 4.2 per cent in February 2024.³ Total outstanding household credit stands at A$2,568 billion,³ a record.

Four RBA hikes in 2026 — in February, March, May and September — more than reversed the 75 basis points of cuts delivered in 2025.¹ The cash rate now sits at 4.6 per cent, its highest setting since the post-GFC tightening cycle peaked at 4.75 per cent in November 2010.¹⁰

The RBA's September 2026 board statement¹ said: 'Inflation remains elevated and some of the upside risks flagged in August are materialising. The conflict in the Middle East has broadened and global energy prices are now much higher than had been assumed in the August forecasts.'¹

The board added it would 'continue to do what it considers necessary to bring inflation sustainably back to target, including increasing the cash rate target further if needed.'¹

The ABS total value of residential dwellings series fell to A$9,730 billion in Q3 2022,⁹ then a 30.8 per cent re-inflation to A$12,723 billion by Q1 2026.⁹ The Q2 2026 reading of A$12,689 billion represents a fall of A$34 billion² — the first quarterly decline since Q3 2022.

The mean dwelling price as at Q2 2026 was A$1,100,000.² Credit growing at 7.3 per cent annually³ against an asset recording its first quarterly decline² — that is the divergence.

The household debt-to-income ratio reached 178.4 per cent in Q2 2026,³ up from a trough of 175.7 per cent in Q3 2025 when cut-cycle relief briefly reduced the burden. Three consecutive quarters of re-ascent have fully reversed that relief, though the ratio remains below the 187.5 per cent peak recorded in Q2 2018.³

The real wage position adds a third dimension to the squeeze. The Wage Price Index rose 3.2 per cent annually in Q2 2026,⁵ against CPI of 3.94 per cent,⁵ producing a real wage decline of approximately 0.74 percentage points. This is a derived estimate, not an ABS series.

The trimmed mean CPI — the RBA's preferred underlying measure — reached 3.6 per cent in Q2 2026,⁶ up from 2.7 per cent in Q2 2025.⁶ That acceleration drove the board's decision to resume tightening.

A denominator note is mandatory when reading the debt-to-income data. The RBA series tracks debt against household disposable income and stood at 178.4 per cent in Q2 2026.³ The OECD measures the same concept against net disposable income, producing a figure of 223 per cent for Australia as at 2024.⁴

Australia ranked third of 20 OECD countries on that basis, behind Norway at 236 per cent and Switzerland at 224 per cent.⁴ Both are official figures. They measure different things and should not be treated as interchangeable.

The RBA series is the correct instrument for tracking change over time on a consistent domestic basis; the OECD figure is the correct instrument for international comparison.

The RBA's October 2026 Financial Stability Review judges that 'most households and businesses with loans are well placed to manage a period of softer economic growth and lower housing prices' and that 'Australian banks are well capitalised and are well placed to continue lending, even in the event of a material economic downturn.'⁸ The system-level resilience finding is grounded in stress-test modelling of capital buffers and arrears rates, and it should not be dismissed.

The A$34 billion quarterly fall sits within a stock valued at A$12,689 billion.² The divergence between credit and collateral growth becomes materially dangerous only if the collateral decline accelerates or the credit book stops performing — neither of which has yet occurred.

As at 4 October 2026, ASX futures priced a 19.3 per cent chance of a hike and no chance of a cut at the 3 November meeting,⁷ so borrowers face a likely hold, some risk of further tightening and little prospect of relief. The RBA's next scheduled meeting is in November 2026, with Q3 2026 CPI data due in late October as the key input.

If trimmed mean inflation continues its upward trajectory from 2.7 per cent in Q2 2025 to 3.6 per cent in Q2 2026,⁶ the case for another hike before year-end will strengthen. The Q3 2026 ABS dwelling stock value release will confirm whether the Q2 2026 fall was the start of a sustained decline or a single-quarter correction.²

The credit keeps growing. The house is worth slightly less.

The rate is the highest in 16 years,¹ and the market is not pricing an exit from any of it.⁷

Just saying.
