Australia’s inflation rate rose to 4.3% in the year to September, intensifying expectations of a fifth interest rate increase by the Reserve Bank of Australia (RBA) this year. The central bank’s preferred measure of underlying inflation, which excludes volatile items such as fuel and food, was reported at 3.6%, well above the RBA’s target of 2.5%.
The latest data released by the Australian Bureau of Statistics (ABS) on Wednesday highlight persistent price pressures across multiple sectors, with housing costs and transport expenses leading the increases. Housing, the largest single component of the Consumer Price Index (CPI), rose by 5.2%, driven in part by higher costs for building materials and labor. Transport costs surged 8.7%, largely attributed to elevated fuel prices linked to ongoing geopolitical tensions involving the United States, Israel, and Iran. Food prices also climbed by 3.2% over the period.
RBA officials have signaled a willingness to raise borrowing costs further in order to curb inflationary pressures. Deputy Governor Andrew Hauser described the inflation figures as “too high” at Senate estimates shortly after the data release, warning of the risk that longer-term inflation expectations could become entrenched. “We don’t think it is necessarily crystallising yet, but it is a particular risk,” Hauser said, emphasizing the bank’s concerns about maintaining inflation within its target range.
The cash rate currently stands at 4.6%, its highest level in 15 years, following four hikes throughout 2026. Economists widely anticipate that the RBA will announce another increase when it meets on November 3.
The inflation rise has come amid a slowing economy, with subdued household spending, a softening labour market, and a weakening housing sector. Stephen Smith, a partner at Deloitte Access Economics, noted the challenge policymakers face in balancing the need to restrain inflation without further dampening economic growth. “The difficulty is that the economy is already slowing,” Smith said, adding that the central bank has “little appetite to allow inflation expectations to drift higher after such a prolonged period above target.”
The political debate around the inflation surge has intensified, with government officials and opposition figures disagreeing on the causes. Treasurer Jim Chalmers acknowledged the government’s role in addressing inflation but pointed to international factors, including the ongoing conflict in the Middle East, as significant contributors to rising costs. “The most important thing that can happen for Australians under pressure is to see an end to this war in the Middle East,” Chalmers stated, citing its impact on global oil prices and subsequent cost-of-living pressures.
Market analysts warn that inflation is likely to remain elevated for the foreseeable future. Josh Gilbert, a market analyst at eToro, characterized the current environment as a “higher-for-longer” inflation scenario and suggested that relief through interest rate cuts may not materialize soon. With consumer prices rising alongside increasing unemployment, many Australian households continue to face financial strain, fueling political unease ahead of upcoming policy decisions.
