Australia May CPI Headline 4.0% y/y vs 4.3% expected, Core 3.6% y/y vs 3.5% expected

Australia's May inflation data released on Wednesday showed a mixed picture: headline CPI rose 4.0% year-on-year, below the 4.3% expected and down from 4.2% in April. On a monthly basis, headline CPI fell 0.7%, compared with a forecast of -0.4% and prior +0.4%. However, the RBA's preferred trimmed mean core CPI came in at 3.6% y/y, above the 3.5% estimate and accelerating from 3.4% in April. Monthly core CPI rose 0.4%, versus 0.3% expected and prior. The weighted median, another core measure, also printed 3.6% y/y, up from 3.5% prior, with a monthly increase of 0.4% versus 0.2% prior.

The divergence between headline and core inflation presents a challenge for the Reserve Bank of Australia. While the headline decline may offer some relief, the stickiness of core measures suggests underlying price pressures remain elevated. For interest rate traders, this data complicates the outlook for RBA policy. Markets had been pricing in a potential rate cut later this year, but a higher-than-expected core reading could delay such expectations. The RBA has consistently emphasized that it will be guided by data, and today's numbers reinforce the need for caution.

Looking ahead, the RBA will likely focus on upcoming quarterly CPI data and labor market reports to gauge the trajectory of inflation. The next RBA meeting is scheduled for August, and markets will be watching for any shift in the board's language. Global factors, including commodity prices and the path of the US dollar, will also influence the Australian dollar and imported inflation. The mixed May data keeps the RBA in a wait-and-see mode, with the balance of risks tilted toward a prolonged pause before any easing.
