AUD Weakened as August Inflation Data Falls Short

The Reserve Bank of Australia (RBA) hiked interest rates on Tuesday, but Wednesday's inflation data threw a curveball. The August consumer price index (CPI) came in below expectations, with overall CPI rising 0.4% month-on-month and core trimmed-mean increasing by just 0.2% month-on-month.

Both figures fell short of forecasts, easing pressure for further rate hikes in the near term. However, the year-on-year increase accelerated from 3.5% to 4.0%, indicating that inflation remains on an upward trajectory.

Housing and transportation were the main contributors to year-on-year inflation, with housing rising 5.7% year over year and transportation increasing 5.6% year over year, driven by fuel prices. Fuel prices surged 14.8% in August alone, driven both by global oil price movements and the full phasing out of government fuel-tax relief measures.

The data indicate that inflation remains above the RBA's 2-3% target range, but the moderation in monthly momentum provides some breathing room for policymakers. The trimmed mean, which excludes highly volatile items such as fuel, apparel, and travel, rose 0.2% month-on-month in August, below the market consensus of 0.3%. Its year-on-year increase remained steady at 3.6%, unchanged for the third consecutive month.
