Why it matters
the Reserve Bank of Australia watches these measures to judge whether inflation is broad-based. When they agree with the headline, the trend is real; when they diverge, a few items are distorting the picture.
How it is calculated
A trimmed mean removes the items with the largest and smallest price changes (for example the top and bottom 15% by weight) and averages the rest; a weighted median takes the price change in the middle of the distribution. Other variants hold mortgage interest costs fixed or use common components.
What changes mean
- A trimmed mean or median near the target is the clearest sign that inflation is under control.
- When the headline jumps but these do not, the move is likely temporary.
Higher than expected: A higher figure than expected makes the Reserve Bank of Australia more likely to keep rates high or raise them: it tends to support the Australian dollar and push bond yields up, and is often a weight on stocks.
Lower than expected: A lower figure than expected gives the Reserve Bank of Australia room to cut or hold rates lower: the Australian dollar tends to soften and bond yields to fall.
A short history
Trimmed means were developed in the 1990s (Bryan and Cecchetti at the Cleveland Fed); the Reserve Bank of Australia and the Bank of Canada give them a central place in their policy.
