Australian TD-MI Inflation Gauge (Oct MM) 0.5% (Prev. 0.3%)

The TD-MI gauge is a privately compiled monthly proxy that runs ahead of Australia's official quarterly CPI, and its role in pricing has historically been that of a direction check rather than a rate-setter: it tends to move the front end and the AUD only insofar as it shifts expectations for the quarterly print, which remains the release the RBA actually conditions on. An acceleration from the prior month's pace reads as an upside surprise in sequence terms, and episodes of this kind have typically fed through to modest hawkish repricing when they land near a policy decision and fade quickly when the official data later diverges, which it has done on previous occasions given the gauge's differing coverage and methodology. The distinction worth drawing is between a one-month firming and a run of firmer prints, since the RBA's reaction function has historically responded to sustained momentum in the trimmed mean rather than to a single monthly proxy. The follow-ons are the next monthly gauge, the quarterly CPI on the calendar, and whether RBA commentary begins to reference monthly inflation signals. As a secondary release, the information content is confirmatory.
