Australia - Trimmed Mean Inflation Rate

Australia's Reserve Bank of Australia (RBA) trimmed mean inflation rate fell to 2.7% year-on-year (YoY) in Q2 2025. This is the lowest rate since Q4 2021, down from 2.9% in Q1 2025. The quarterly trimmed mean CPI also decreased to 0.6% in the three months to June 2025, from 0.7% in the first quarter. Annual Services inflation slowed to 3.3% in Q2 2025 from 3.7% in Q1 2025, partly due to moderating price rises in financial and insurance services. Annual Goods inflation decreased to 1.1% in Q2 2025 from 1.3% in Q1 2025, driven by a 10.0% annual fall in automotive fuel prices. These disinflationary pressures coincided with a rise in the unemployment rate to 4.3% in June 2025, the highest level since November 2021 and a slowdown in economic growth with Q1 2025 GDP rising by 1.3% year-on-year. These factors provided context for the RBA to consider monetary policy easing. Australia's record low trimmed mean inflation rate was 1.1% in Q1 2021 and its record high was 10.7% in Q1 1983.

Australia - Trimmed Mean Inflation Rate : Definition
Australia's trimmed mean inflation rate is a core inflation measure. It removes the 15% of items with the largest and smallest price changes, focusing on the central tendency of price movements, thus reducing the impact of volatile components on the overall inflation figure.
