What is Trimmed Mean Inflation?
Trimmed-mean inflation (the RBA's headline core measure) removes the largest and smallest price changes each quarter and averages the rest. It is the cleanest read on Australian underlying inflation.
Why it matters for FX
The RBA explicitly targets trimmed-mean inflation in the 2-3 percent band. Surprises in the quarterly print move AUD more than headline CPI because they directly drive the rate-path repricing.
How to read this page
Watch year-over-year change vs the 2-3 percent RBA band. Annualised quarterly run rate is the high-frequency signal.
