GDP Chain Price Index QoQ
A quarterly national-accounts measure of price change across the goods and services included in GDP.
Full explanation
Australia's GDP Chain Price Index QoQ measures the quarter-to-quarter change in prices across the goods and services included in gross domestic product. It is a broad national-accounts price measure, rather than a measure of household living costs alone. The Australian Bureau of Statistics publishes it with the quarterly national accounts, using chain-price methodology that updates component weights over time. Movements can reflect prices for consumption, investment, government spending and trade-related components within GDP.
Why traders watch it
Traders watch it as part of Australia’s quarterly GDP release because it helps distinguish changes in nominal GDP caused by prices from those caused by real output. It can also provide context on economy-wide price pressures, commodity-price effects and the terms of trade, all of which may influence expectations for Australian interest rates and bond yields.
Market interpretation
- Australian dollar
- Can affect interpretations of domestic price pressure, nominal income and commodity-related trade-price developments within the GDP release.
- Australian government bonds
- May influence views on inflation conditions and the policy backdrop when considered with broader activity and inflation data.
Stronger vs weaker outcomes
A higher-than-expected quarterly increase could possibly indicate stronger broad price growth within the economy or larger trade-price effects than anticipated. A lower or negative result could possibly indicate softer economy-wide price movements. Its significance depends on the underlying GDP growth result, terms of trade and the components driving the change.
A higher reading than expected may indicate firmer price growth across GDP components or stronger trade-price effects during the quarter.
A lower reading than expected may indicate softer broad price movements or weaker trade-price effects during the quarter.
Higher readings can point to firmer economy-wide price movements, while lower readings can point to softer price movements; the composition of the change matters.
Typical volatility
Moderate. This is not a consumer inflation index and should not be read as a direct measure of household cost-of-living pressure. It is published in original terms and can move materially when export and import prices change, particularly in a commodity-intensive economy.
Trading considerations
- Read the result alongside real GDP growth and nominal GDP rather than in isolation.
- Check the terms of trade and export/import price movements for possible drivers.
- Note that the Australian release presents the GDP chain price index in original terms.
- Allow for revisions to national-accounts data and changes to historical estimates.
- Compare it with consumer-price and producer-price indicators, which cover different parts of the economy.
