No prior knowledge assumed. Every three months the news reports inflation as a single number: how much prices rose over the past year. That number matters, but it answers only one question. For anyone who owns, rents, builds or buys a home, two more questions matter just as much. How far have prices climbed above what used to be normal? And are the costs of housing rising faster than everything else? #### The simple version Think of the Consumer Price Index as a supermarket trolley filled with everything a household buys: food, fuel, clothing, rent, electricity, a new home. The headline inflation figure tells you how much more that trolley costs than it did a year ago. Inflation (21220) asks a longer question. It looks at five separate measures of prices and asks how far each one now sits above its usual level across the last fifteen years. The five are: the price of the whole trolley; the price of the housing items inside it; the price of the trolley with the most unusual price jumps and falls taken out; the price builders pay to construct a house; and the rate of inflation households expect over the year ahead. APN combines the five into one reading, with each measure counting equally. #### Why this matters for property Inflation is not an abstract statistic for property. It sets what it would cost to rebuild a home from scratch. It sets the starting cost for anyone building new housing. And it changes what a given rent or sale price is really worth once rising prices are taken into account. When housing costs rise faster than prices generally, a dollar of rent or a dollar of sale proceeds buys less than the headline figure suggests. #### What has happened lately In the June quarter of 2026, all five measures sat above their fifteen-year averages, and the combined reading moved more than two standard deviations above average for the first time. A standard deviation is simply the usual distance a reading strays from its average; APN calls a reading two of those distances away a **Two Standard Deviation Event**, because readings that far out are uncommon. Housing is the measure furthest above its normal level. Housing costs are also rising faster than prices overall: up 6.8 per cent over the year to June 2026, against 3.9 per cent for the whole trolley. That gap opened in the second half of 2025. It has not always been there: through late 2024 and the first half of 2025, housing costs rose more slowly than prices overall. Builders' costs have picked up too, rising 5.9 per cent over the year to June 2026, compared with less than half of one per cent a year earlier. The authorities have responded. The Reserve Bank raised the cash rate three times in 2026, in February, March and May, taking it from 3.60 per cent to 4.35 per cent. From 1 February 2026, the banking regulator, APRA, also limited how much new home lending banks can write at six or more times a borrower's income. #### How APN measures this Rather than reacting to each quarter's headline, Inflation (21220) compares today's prices with fifteen years of history and asks whether they are ordinary or unusual. Each measure is compared against its own history first, so that measures on very different scales can be placed side by side, and then the five are averaged. The current answer is that prices are about as far above normal as the record goes: the June quarter 2026 reading is the highest of the 22 quarters in which all five measures are available. #### What this means for you **If you are buying:** the costs that come with a home, including building, repairs, utilities and rates, have risen well above their long-run level. Budget for those costs to stay high rather than fall back quickly. **If you already own:** the cost of rebuilding your home has likely risen faster than the general cost of living, which is why checking your insured value matters more now than it did a few years ago. **If you rent or are a landlord:** housing costs sit on both sides of a lease. For a landlord they are costs to cover; for a tenant they show up in what the home costs to occupy. The same figure pulls in two directions depending on which side of the lease you are on. **If you are selling:** a higher sale price today does not all represent a gain. Part of it reflects the general rise in prices, and part reflects how much more it now costs to build or buy an equivalent home. **The one-sentence version:** prices that shape the cost of housing now sit further above their fifteen-year normal than at any point in the record, and housing costs are rising faster than prices overall.
