Australian headline inflation cooled to 4.0% in the year to May, down from 4.2%; the move is mechanical, and the underlying picture did not soften. The RBA’s preferred trimmed mean rose to 3.6% from 3.4%, and the headline fall leans on fuel, where the lower oil prices behind gold’s slide did much of the work.
Automotive fuel fell 11.9% on the month, carrying the 1 April excise halving and the recent drop in world crude. Strip that and the sticky components held; electricity is 21.1% higher over the year as government rebates roll off, and housing rose 6.5%. Headline CPI fell 0.7% in original terms on the month and 0.1% seasonally adjusted.
The read for the RBA is unhelpful. Three cash-rate increases into 2026, a cooler headline driven by a tax change and cheaper oil gives no cover to ease while the trimmed mean climbs; the bank stays restrictive. For the Australian dollar that is supportive at the margin, not the pivot some had positioned for.
