Ai Group Australian Industry Index
Published:
A monthly survey-based gauge of whether activity in Australian industrial sectors is expanding or contracting.
Full explanation
The Ai Group Australian Industry Index is a monthly survey of Australian industrial businesses that shows whether activity is expanding or contracting. It is a diffusion index: readings above zero indicate expansion across more firms, while readings below zero indicate contraction. The survey covers industrial sectors and related indicators such as activity, new orders, employment, prices and capacity utilisation. Results are seasonally adjusted and are based on responses from a national sample of businesses, with sector weights informed by Australian industry classifications and gross value added data.
Why traders watch it
Traders watch the index as an early read on Australian industrial momentum, cost pressure and demand conditions before some official activity data are released. It can influence expectations for Australian growth, inflation pressure and Reserve Bank of Australia policy risk.
Market interpretation
- AUD
- The Australian dollar may become more sensitive to the release when the index materially changes expectations for domestic growth or inflation pressure.
- Australian rates
- Rates markets may focus on whether the details point to stronger demand, weaker activity or persistent cost pressure.
- Australian equities
- Industrial and cyclical shares may react to signals about orders, activity and capacity constraints.
Stronger vs weaker outcomes
A stronger-than-expected reading may suggest broader industrial expansion, firmer demand or persistent capacity pressure, while a weaker-than-expected reading may suggest softer activity or declining order momentum. The market reaction can depend on whether the move is driven by demand, employment, prices or supply constraints.
A higher-than-expected reading may point to broader expansion in Australian industry or improving business momentum.
A lower-than-expected reading may point to softer industrial conditions or a narrower base of expanding firms.
Higher readings generally suggest broader expansion; lower readings generally suggest weaker or more uneven industrial activity.
Typical volatility
Moderate. Survey diffusion indexes measure the breadth of change rather than the exact size of output growth. One monthly reading can be volatile, and sector-level details may matter more than the headline when conditions are uneven across industries.
Trading considerations
- Check whether the headline move is supported by new orders, employment and price indicators.
- Remember that diffusion indexes show breadth of change, not the exact change in output volume.
- Compare the survey with other Australian business surveys and official activity data for confirmation.
- Watch for AUD liquidity conditions around the release time, especially if it coincides with other Asia-Pacific data.
