Australian MI Inflation Gauge YY (Jul) 4.0% (Prev. 3.9%)

The Melbourne Institute gauge is a private-sector monthly proxy that sits in the shadow of the quarterly CPI, which remains the release the RBA actually conditions on. A marginal uptick of this size typically registers only at the front of the AUD curve and in the currency against the dollar and kiwi, and only insofar as it shifts perceived risk around the next quarterly print rather than in its own right. The relevant distinction is between this series and the ABS monthly indicator: the latter has progressively displaced the MI gauge as the market's preferred inter-quarter read, so the signal here is corroborative rather than primary. Historically, private gauges of this kind have mattered most when they break a run of deceleration or confirm a trend the official data later validated. What follows is the monthly ABS series and then the quarterly CPI, where trimmed mean rather than headline has been the policy-relevant measure through the current cycle.
