Commodity Prices YoY
Published:
The RBA Index of Commodity Prices YoY tracks annual changes in prices for major Australian export commodities, a key input for terms-of-trade and AUD analysis.
Full explanation
Commodity Prices YoY measures how the Reserve Bank of Australia's index of key Australian export commodity prices has changed from the same month a year earlier. The index tracks commodities important to Australia's export income, such as bulk commodities, rural commodities and base metals. The RBA publishes the Index of Commodity Prices monthly and reports the index in SDR terms, with Australian-dollar comparisons also commonly shown. Because recent months can use preliminary estimates for some bulk export prices, the figures may be revised as better information becomes available.
Why traders watch it
Australia is a major commodity exporter, so shifts in export commodity prices can affect national income, the terms of trade, inflation pressures, fiscal receipts and AUD sentiment.
Market interpretation
- AUD
- Can influence sentiment toward the Australian dollar through terms-of-trade and export-income expectations.
- Australian rates
- Large commodity-price moves can affect inflation and growth expectations, which may influence RBA pricing.
- Australian equities
- Resource-sector shares may be sensitive to the commodity-price backdrop reflected in the index.
Stronger vs weaker outcomes
A stronger-than-expected yearly rise may point to improving export-price conditions and could support expectations for higher income or terms-of-trade strength. A weaker-than-expected result may suggest softer commodity-driven income momentum, especially if driven by iron ore, coal, LNG or other high-weight exports.
A higher-than-expected yearly increase can indicate stronger export-price momentum and a potentially more supportive terms-of-trade backdrop.
A lower-than-expected reading can indicate weaker export-price momentum and less support from commodity income.
Higher readings generally point to stronger commodity export prices; lower readings point to weaker commodity export prices.
Typical volatility
Moderate. The index is not the same as consumer inflation, and AUD reactions also depend on global risk appetite, China demand, interest-rate expectations and whether price moves are already reflected in spot commodity markets.
Trading considerations
- Separate SDR-based moves from Australian-dollar moves, because exchange-rate effects can change the local-income interpretation.
- Check which commodity groups are driving the change, especially bulk commodities with high export relevance.
- Treat preliminary estimates carefully because some recent-month export prices may be revised.
- Compare the release with China demand indicators, iron ore and coal prices, and RBA policy expectations.
