Australia’s inflation and RBA rate hikes amid Iran war oil price shock
Consensus Summary
Australia’s inflation remains stubbornly above the Reserve Bank’s 2-3% target, with February data showing 3.7% annual growth and underlying inflation steady at 3.3%. The RBA raised interest rates in March, anticipating further hikes this year as markets now price in a cash rate peaking near 4.6% by year-end. The escalation of the Iran war on February 28 has intensified concerns, with petrol prices surging 29% since the conflict began, pushing expectations of inflation exceeding 5% by mid-2026. Economists warn the March data, released April 24, will reflect these energy price shocks, potentially derailing the RBA’s earlier forecast of a 4.2% peak. While February’s figures showed housing and food as key inflation drivers, the Iran conflict adds a new supply-side shock, complicating the RBA’s balancing act between curbing inflation and avoiding recession. Treasurer Jim Chalmers has acknowledged the war will worsen costs but declined to interfere with the RBA’s independent decisions, emphasizing the need for a coordinated response to the fifth major economic shock in two decades.

- Westpac’s Luci Ellis noted ‘inflation expectations have surged’ due to fuel price spikes, which the RBA aims to prevent from becoming embedded.
