Australia’s Melbourne Institute Monthly Inflation Gauge rose 0.3% month-on-month in September 2026, slowing from a 0.5% increase in the previous month and marking the softest reading since June. The moderation suggests that tighter monetary policy is helping curb price pressures, with the three cash rate increases since the start of the year tightening financial conditions as economic activity slows. However, inflation remains too high, with some upside risks materialising. Annual inflation accelerated to 4.0% in August from 3.5% in July, the highest in three months and still above the Reserve Bank of Australia’s 2–3% target range. Meanwhile, weak productivity growth continues to constrain potential output, while uncertainty over the economic impact of the housing market downturn adds to the outlook risks. source: Melbourne Institute

Australia Inflation Gauge Hits 3-Month Low

Australia Inflation Gauge Eases
Australia’s Melbourne Institute Monthly Inflation Gauge rose 0.5% month-on-month in August 2026, slowing from a 1.0% increase in the previous month and marking the second straight month of growth. The moderation suggested price pressures are moderating from their March peak, although underlying inflation remains elevated. The Reserve Bank of Australia’s August meeting minutes noted that underlying price growth had eased slightly from late 2025 levels, but inflation remained “too high.” Officials also highlighted upside risks from the Middle East conflict, the global AI boom and weak productivity growth. Meanwhile, annual inflation eased to 3.5% in July from 3.8% in June, the lowest in eight months, but remained above the RBA’s 2–3% target range. The central bank expects inflation to return to target only gradually, by late 2027, keeping the outlook for monetary policy cautious.

Australia Inflation Gauge Rebounds as Core Price Pressures Linger
Australia's Melbourne Institute Monthly Inflation Gauge rose 1.0% month-on-month in July 2026, reversing a 0.4% decline in June and marking its first increase since April, pointing to renewed inflationary pressures. The reading aligns with the Reserve Bank of Australia's June meeting minutes, which indicated that underlying price pressures were expected to intensify in the June quarter. Official data showed headline inflation eased to 3.8% in June from May's 4.0%, mainly due to lower fuel prices. However, underlying inflation remained persistent, with the trimmed mean accelerating to 3.6% from 3.4% as businesses passed through higher costs linked to Middle East tensions. Governor Michele Bullock recently reiterated that underlying inflation remains too high and warned it could rise further as higher oil prices stemming from the Iran conflict feed into broader prices, reinforcing expectations that the RBA will remain cautious on policy easing.
