Australian Inflation Jumps to 4.1%, Consumer Prices High
Synopsis
Australia's consumer price index surged 1.4% in Q1 2026, the sharpest quarterly rise since late 2023, pushing annual inflation to 4.1%. Fuel prices jumped almost 33% in March alone as the Iran war and Strait of Hormuz closure drove energy costs higher. Core inflation rose to 3.5% annually, above the RBA's 2-3% target. Markets are pricing a 76% chance of a third RBA rate hike in May. Treasurer Jim Chalmers warned the worst is still ahead as the oil shock flows through the broader economy.
Australia's September inflation surges to its highest level for over a year almost entirely due to the war in the Middle East sending petrol prices flying. Next week's rate hike is now a near-enough lock and the misery isn’t close to ceasing.
Key Highlights
- Australia’s Q1 2026 CPI was up 1.4% (the biggest quarterly jump since late 2023)
- Core inflation, as measured by the trimmed mean, increased to 3.5% year-on-year, well above the RBA target band around 2-3%.
- A third RBA rate hike in May is now seen as a near-sure thing, with markets pricing in a 76% chance the cash rate will rise to 4.35%.
- Treasurer Jim Chalmers said inflation would most likely peak higher in the coming months as the oil shock reverberated through the wider economy.
Australia’s Inflation Increase
The consumer price index soared 1.4% in the March quarter of 2026, its biggest quarterly increase since late 2023, to see annualised inflation push back up to 4.1% from 3.6% the previous quarter. Wednesday’s data from the Australian Bureau of Statistics shows just the initial hit of the Iran war and closure of the Strait of Hormuz.
The biggest single factor was fuel, with petrol prices soaring almost 33 per cent between February and March. And the numbers make for uncomfortable reading for Australian households already stretched to breaking point by two rate hikes this year.
Core Inflation Is Too High Yet, But Not As Bad As Feared
The trimmed mean, the RBA’s preferred measure of core inflation that excludes the 30 per cent most volatile items including petrol, was 0.8 per cent higher in the quarter and gained an annualised 3.5 per cent, up from 3.4 per cent. It was still a bit weaker than the 0.9 per cent quarterly increase that analysts expected, but offered some comfort. Markets reduced their odds on a May rate rise from 85 per cent to 76 per cent on the result, with the Australian dollar retreating 0.2 per cent to US$0.7170. Another 62 basis points of tightening, roughly two and a half more hikes, is still priced in for the rest of the year
Bad News, Worst Still To Come, Treasurer Cautions of Wider Price Shock
This data today only picks up the beginning of the inflation story from the Middle East conflict so far. The Strait of Hormuz remains closed, and oil is around $110 a barrel, nearly 60 per cent higher than before the war started. “Inflation is much more likely to be at the top,” Treasurer Jim Chalmers told reporters. We predict that in a matter of months, the implications of this oil shock should ripple out to broader prices, sufficiently broadly to influence trimmed mean data as well.” Deloitte Access Economics partner Stephen Smith put it bluntly: “The CPI print today is indicative of a rate hike from the RBA next week. That said, Australia’s initial position on inflation as we head into this crisis, probably robs the central bank of much wiggle-room.”
How Economists Make Sense Of The May Rate Decision
Still think ANZ will hike in May, but that will be the last move this cycle. The RBA will be “concerned about how forcefully it can push rates because of the labour market,” Adam Boyton, head of Australian economics said. IG analyst Tony Sycamore said if the RBA believed the peak of the inflation scare was over and trimmed mean inflation would remain within the RBA’s own 3.7% forecast by mid-year, there was an “argument for holding in May”. So far this year, there have been two hikes lifting the cash rate to 4.1% and the May meeting will be one of the most scrutinised for years.
FAQs
- Why is fuel such a huge driver of inflation today?
In March, the Iran war seemed to have proven successful; 33% more automotive fuel was a cost of pumping oil when one-ninth of the globe’s supply on arrival via this route was choked off: 20% of all our oil goes through the Strait of Hormuz.
- What about the reduction in petrol excise, will that make a difference?
The fuel excise was halved from April, so some downward pressure in the Q2 inflation data should occur. However, economists are warning that wider-ranging price increases are still to come.
- How many further rate increases are priced in for this year?
Currently, markets are pricing about two additional and a half hikes prior to year's end pushing the cash towards 4.75%. In a note, ANZ said it believed May would likely be the final rate increase this cycle.
