The Relief Rebound: Why Australia's Inflation Win Expires on Sunday

The short version: Headline inflation fell because government relief was suppressing measured prices, not because the cost of living got easier. Electricity is up 22.4% precisely because rebates ended, the 16c/litre fuel excise discount dies at midnight on Sunday 2 August, and oil is back above US$100. Underlying inflation didn't move at all. Treat August as a hold, not a turning point.

What the June figures actually said

The ABS released the June CPI on 29 July. Headline inflation came in at 3.8% annually - softer than the 4.0% consensus expected - with a quarterly movement of 0.6%. But the measure the Reserve Bank actually steers by, the trimmed mean, didn't budge: 3.6%, unchanged from May, and still sitting above the top of the RBA's 2-3% target band.

The improvement came almost entirely from one place. Transport inflation collapsed to just 0.1% over the year, down from 3.3% in May, as global oil prices fell through June and the fuel excise discount held pump prices down. Goods inflation eased to a four-month low of 3.5%.

Meanwhile, the parts of the basket that matter most to anyone who owns or rents a home went the other way. Housing was the single largest contributor to annual inflation, up 6.8%, and services inflation accelerated to 4.0%. Inside housing:

• Electricity: +22.4% over the year
• New dwellings: +5.8% - the fastest in nearly three years, as project builders passed through labour and materials costs
• Rents: +3.6%, with the national vacancy rate still around 1.6% against a decade average of 2.5%

The relief rebound: how help becomes inflation later

That 22.4% electricity figure isn't a story about generators suddenly gouging households. As the ABS's head of price statistics Rachael McCririck put it, "electricity remains one of the biggest contributors to annual inflation, with costs 22.4 per cent higher than 12 months ago" - and the driver was the expiry of Commonwealth and state electricity rebates.

This is the mechanism almost nobody names, and it matters enormously for anyone with a home loan. When a government pays part of your power bill, the CPI records a lower price. When that payment stops, the CPI records the rebound as inflation - even though nothing about the underlying cost changed. Relief doesn't remove cost pressure. It defers how the cost pressure gets measured.

And the same machinery is about to run again. The remaining 16 cent per litre fuel excise discount ends at midnight on Sunday 2 August, with full excise applying from Monday. Treasurer Jim Chalmers, confirming the end date, said the relief "has played a really important role helping to take some of the sting out of these cost-of-living pressures". He's right - and that's exactly the problem. The sting was taken out of the numbers as well as the budgets, and it's about to be put back. For a typical tank, it's roughly $10 per fill from Monday.

The oil shock that isn't in the data yet

Now layer on the variable no forecast contained a month ago. Brent crude was back above US$100 a barrel in late July as the conflict in Iran escalated and the Strait of Hormuz was effectively closed. Sustained crude above US$100 usually takes two to four weeks to work through to Australian bowsers.

So the excise restoration and the crude pass-through land in the same fortnight - in August data the RBA won't read until well after its next meeting. The number that just calmed the market describes a month that no longer resembles the one we're about to have.

Why the RBA still can't relax

None of this makes a hike likely on 10-11 August. Markets have it near zero, NAB and ANZ both expect a hold, and Westpac has been the lone major backing a rise. The June labour force figures did show the economy adding 76,300 jobs with unemployment at 4.4%, which is not a picture of an economy buckling - but with underlying inflation flat rather than falling, the board has no reason to move in either direction.

What it does rule out is the thing plenty of borrowers are quietly hoping for. Governor Michele Bullock has been blunt: "if it looks like inflation is not coming down then I think the Board have some difficult decisions to make in terms of raising interest rates". A trimmed mean stuck at 3.6% is not inflation coming down. It's inflation parked outside the target band while the RBA waits.

Here's the uncomfortable circularity. Housing is the biggest contributor to the inflation keeping rates high - and high rates are part of why new dwelling construction costs keep climbing and rental supply stays thin. The problem the RBA is fighting with rates is substantially a problem that rates aren't well designed to fix.

The strategist's view: what to actually do before 11 August

Roy Morgan has mortgage stress at 30.3% of holders, the highest since June 2024, and Equifax has mortgage demand down 14% year-on-year with no state or age group growing. This is a market where fewer people are competing and more people are stretched. That combination rewards preparation, not waiting.

• If you're on a variable rate: don't wait for August to "confirm" anything - it won't. A hold has been the base case for weeks. What's worth doing this fortnight is a proper review of where your rate sits against what's actually available to a borrower with your equity and history, because lenders have kept repricing independently of the RBA all year.
• If you're weighing fixing: understand that fixed pricing moves off swap and bond markets, not the cash rate. Lenders trimming fixed rates are pricing a view about 2027, not offering charity. Fixing is choosing which side of that bet to take - a split can be the honest answer when you genuinely don't know.
• If you're pre-approved: check the expiry date and the assumptions. Assessed living expenses are sensitive to energy and fuel costs, and both are heading up from Monday. An approval issued in autumn may assess differently on a resubmission in spring. Our borrowing power estimator is a quick way to sanity-check the direction.
• If you're on the sidelines: this is the most negotiable market in years - the median vendor discount across the capitals widened to 3.6% in the June quarter. Buyer leverage is real right now, and it exists precisely because most people have stopped looking.
• Everyone: build the August step-up into your own numbers before your lender does. Fuel and power are rising from Monday, and the mortgage calculator is only honest if the rest of the budget around it is.

The lesson of this CPI print isn't that inflation is beaten. It's that a headline built on temporary relief tells you about policy timing, not about your cost of living. Plan off the underlying number - and off your own bills.

Frequently Asked Questions

What was Australia's inflation rate in June 2026?

Headline CPI rose 3.8% in the 12 months to June 2026, down from 4.0% in the year to May, per ABS figures released on 29 July 2026. The trimmed mean - the RBA's preferred underlying measure - was unchanged at 3.6%, still above the 2-3% target band. The quarterly CPI movement was 0.6%.

Why did electricity prices rise 22.4% in Australia?

Electricity was 22.4% more expensive in the year to June 2026 largely because Commonwealth and state government rebates expired. While rebates were being paid they reduced the price households were measured as paying; when they stopped, the measured price rebounded. The ABS named electricity as one of the largest contributors to annual inflation.

When does the fuel excise cut end in Australia?

The remaining 16 cent per litre discount ends at midnight on Sunday 2 August 2026, with full excise applying from Monday 3 August. Treasurer Jim Chalmers confirmed the date. For a typical tank it is worth roughly $10 per fill, and it arrives while Brent crude is above US$100 a barrel.

Will the RBA raise interest rates in August 2026?

Markets cut the probability of an August rise to close to zero after the June CPI release. The board meets on 10-11 August 2026. NAB and ANZ expect a hold; Westpac has been the only major bank backing a hike. The cash rate is 4.35% following three increases in the first half of 2026.

What does the June 2026 CPI mean for mortgage holders?

It lowers the near-term risk of another rise, but it is not a signal that cuts are coming. Underlying inflation is stuck at 3.6% and housing is the largest single contributor to annual inflation at 6.8%. Treat August as a likely hold rather than a turning point, and budget for household running costs to rise as fuel excise relief ends.
