Reading Inflation for Client Strategy
Clients experience inflation as three separate frustrations: rebuild and insurance quotes that keep rising, rent reviews that outpace their expectations, and construction budgets that do not survive to completion. The certified record of Inflation (21220) explains all three as one system, and it separates two questions clients tend to run together: how high prices are, and how fast they are still rising.
The environment in certified numbers
For the June quarter 2026, the certified composite reads +2.1049σ, with an empirical position of 100.0, ranked against 22 quarters: the highest reading of every quarter in which all five inputs are available, and the first above +2σ. The five inputs:
Housing CPI +2.5220σ, the highest reading in its record since 2011. Headline CPI +2.3236σ. Trimmed Mean CPI +2.3236σ. PPI House Construction +2.1540σ. Consumer inflation expectations +1.2014σ, at 5.47 per cent.
Annual growth over the year to June 2026: housing costs 6.80 per cent, headline CPI 3.94 per cent, trimmed mean 3.65 per cent, house construction producer prices 5.92 per cent.
Level and pace: two different client questions
The Z-scores above describe price levels: how far prices sit above their average over the baseline years. The annual growth rates describe pace. The distinction answers the most common client question, “isn’t inflation coming down?” Headline annual inflation did ease slightly between the March and June quarters of 2026, from 4.09 to 3.94 per cent, and housing cost growth eased from 7.15 to 6.80 per cent. But prices are still rising, so the level keeps moving further above its long-run average. A client can be told, accurately, that the pace has eased a little while the costs they face have not fallen, and households expect prices to keep rising.
Housing costs against the headline
Housing costs are rising 2.9 percentage points a year faster than prices overall. That gap is a current condition, not a permanent feature. It opened in the September quarter 2025. Before that, from the September quarter 2024 to the June quarter 2025, housing costs rose more slowly than headline CPI, and at the widest point in the December quarter 2024 the shortfall was 1.4 percentage points. The previous period of housing costs running ahead lasted from late 2021 to mid-2024. When advising on holding costs, cite the current gap with its date, and do not describe it as a permanent premium.
Construction costs and budget risk
House construction producer prices rose 5.92 per cent over the year to June 2026, up from 0.35 per cent over the year to June 2025. In the March quarter 2026 the index moved above +2σ for the first time in the record, and it rose further in the June quarter. For developers and anyone contracting a build, this is the figure to watch: fixed-price contracts, presales and feasibility studies priced on 2025 cost assumptions carry escalation risk against a cost base now rising at close to 6 per cent a year.
The policy setting
The Reserve Bank raised the cash rate three times in 2026, from 3.60 per cent to 3.85 per cent in February, 4.10 per cent in March and 4.35 per cent in May. From 1 February 2026, APRA limited new residential mortgage lending at a debt-to-income ratio of six or more to 20 per cent of each bank’s new lending. Interest Rates (21210) reads +0.9807σ for the June quarter 2026. Inflation and borrowing costs are both above their baseline averages at the same time.
Practitioner implications
Buyers agents: replacement-cost and insured-value conversations should reference housing costs specifically, now rising 6.80 per cent a year, not the headline inflation figure clients see reported.
Mortgage brokers: clients face elevated prices and a cash rate raised three times this year, alongside a regulatory limit on high debt-to-income lending. Serviceability conversations should allow for both costs and rates staying at current levels for some time.
Property managers: rent-review discussions often cite headline CPI. Housing costs are running well ahead of it, which bears on both the landlord’s holding costs and the tenant’s capacity to pay.
Developers: the acceleration in construction producer prices through the year to June 2026 is the clearest data-backed case for explicit escalation provisions in contracts and feasibilities prepared from here.
