Australia's trimmed mean CPI rose to 3.6% yoy, highest since late 2024, signaling persistent underlying inflation even as headline eased to 4.0%.

Australia's May inflation report offered a split verdict that complicates the RBA's next move. Headline CPI fell 0.7% month-on-month and the annual rate eased from 4.2% to 4.0%, both missing market expectations. The decline was driven almost entirely by fuel: automotive costs plunged 11.9% in May after a 7.0% fall in April, as lower global oil prices combined with the government's excise reduction.
The underlying story was less reassuring. The RBA's preferred trimmed mean measure rose 0.4% month-on-month, above forecasts, and the annual rate accelerated from 3.4% to 3.6% – the highest reading since late 2024. The headline improvement came from energy-related factors, not a broad easing in domestic price pressures. Policymakers focus on whether underlying inflation is becoming embedded, and this report suggests that risk has not diminished.
The split between goods and services inflation highlights the challenge. Goods inflation slowed from 4.7% year-on-year to 4.2% as lower fuel costs filtered through. Services inflation moved in the opposite direction, accelerating from 3.5% to 3.7%. Housing remained the largest contributor to overall inflation, rising 6.5% year-on-year, while food and transport costs stayed elevated.
For the RBA, the report does not provide a clear answer on whether tightening is finished. The case for a pause rests on the headline drop and the lagged pass-through of fuel to other categories. The case for further action rests on the core trend, which shows no sign of bending. Governor Bullock and her board next meet in August, with the July CPI print likely to be the deciding input before that decision.
The market reaction was muted in early trading. The Australian dollar slipped marginally against the greenback, while three-year bond yields edged lower as traders weighed the headline miss against the core firmness. The data gives the RBA little reason to signal a cut is near and keeps the currency vulnerable to any further hawkish surprise in the next release.
