In Australia, the trimmed mean CPI is the weighted average of the central 70% of price changes in the Consumer Price Index (CPI) basket, after excluding the 15% of items with the largest increases and decreases. By removing extreme price movements, this measure provides a clearer view of underlying inflation trends in the Australian economy.
A higher than expected figure should be seen as positive (bullish) for the AUD while a lower than expected figure should be seen as negative (bearish) for the AUD.
