Australia’s inflation rate accelerated sharply in March, with headline consumer prices rising 4.6 per cent annually, up from 3.7 per cent in February, as surging fuel costs linked to conflict in the Middle East pushed up household expenses.
New data released by the Australian Bureau of Statistics (ABS) showed the Consumer Price Index (CPI) rose 1.1 per cent in March, driven largely by transport costs, which increased 9.2 per cent over the month.
Automotive fuel prices were the standout contributor, rising 32.8 per cent in March following global oil supply disruptions connected to the conflict in the Middle East and interruptions to shipping through the Strait of Hormuz.
Despite the sharp jump in headline inflation, trimmed mean inflation – the Reserve Bank of Australia’s preferred measure of underlying inflation – remained steady at 3.3 per cent, suggesting broader price pressures across the economy have not accelerated at the same pace.
The ABS noted that trimmed mean inflation can provide a clearer picture of long-term inflation trends when highly volatile items such as fuel experience large price swings.
The Reserve Bank of Australia aims to keep inflation around 2.5 per cent over the medium term, meaning the latest figures are likely to intensify debate over future interest rate decisions.
According to a newly released economic commentary from the Bank of Sydney, inflation was already running above target before the latest fuel shock.
Bank of Sydney consulting economist Ivan Colhoun said the March quarter CPI confirmed inflation remains stubbornly high, even before the full impact of rising fuel costs is felt.
“Recent data confirms that Australian inflation remains too high,” he said.
Colhoun said the Reserve Bank’s trimmed mean inflation measure of 3.5 per cent annually still compared unfavourably with the central bank’s target.
“The outcomes were a little better than expected with the important trimmed mean measure printing at 0.8% q/q and 3.5% y/y. This compares unfavourably with the RBA’s 2.5% target for inflation,” he said.
He said inflationary pressure linked to the Strait of Hormuz remained the most important near-term risk for Australia’s economy.
“The situation in the Strait of Hormuz continues to be the most important near-term driver of the economic outlook,” Colhoun said. “An extended disruption could lead to global recession, while a near-term resolution would likely support improving outlooks in both the Australian and US economies.”
The Strait of Hormuz, through which roughly one-fifth of global energy supplies pass each day, has become a critical factor in oil price volatility.
Colhoun said there were two possible paths for Australia’s economy depending on how long disruptions persisted.
If supply interruptions continue, businesses could face higher transport and production costs, while households may reduce spending due to mounting living expenses.
“The increase in business costs would likely lead to recession as consumer demand drops and firms respond by cutting production and staff,” he said.
However, a quicker resolution in the Middle East could see economic conditions stabilise.
“If the period of closure totalled only three months, there would be a good prospect of the re-establishment of the pre-existing more favourable economic outlook,” Colhoun said.
The inflation figures have intensified speculation that the Reserve Bank may consider another interest rate rise at its next board meeting.
Colhoun said that, in normal circumstances, inflation at current levels would likely justify tighter monetary policy.
“If it were not for the Iran conflict, the RBA would likely increase interest rates again to be more confident inflation will return to target, perhaps earlier than the mid-2028 date forecast in February,” he said.
However, he noted that worsening business and consumer confidence, alongside falling auction clearance rates, complicated the Reserve Bank’s decision-making.
“A prudent course of action could also be to await further information on how the conflict might play out for the economy,” he said.
Federal Treasurer Jim Chalmers said the latest figures showed Australians were paying a heavy price for instability overseas, particularly through rising petrol and diesel costs.
The Federal Government’s temporary cut to the fuel excise, introduced in April, is expected to provide some short-term relief, although economists warn inflation could remain elevated in the coming months.
Bank of Sydney also noted that businesses are now confronting a difficult mix of rising operating costs and weaker demand.
“It’s again a very uncertain time and one that for many businesses will include both a drop in consumer demand and a substantial increase in transport and other input costs,” Colhoun said.
Economists continue to forecast inflation could rise closer to 5 per cent in the months ahead, depending on global energy prices and whether oil supply disruptions persist.
For households already grappling with mortgage repayments, food prices and higher utility bills, the latest inflation spike signals further pressure on the cost of living in the months ahead.
