Australia exports metals to China, so the Australian dollar often tracks commodity prices. Copper is a popular proxy for Chinese industrial demand and shows a decent correlation with AUD at times.
For scalpers, the link provides background more than a trigger. A sharp move in copper futures during the Asian or London session can precede a move in AUD/USD, though the response varies and is not guaranteed.
The relationship weakens when other drivers dominate: Fed policy, risk sentiment, or Australian rate expectations. During those periods, copper is a poor guide.
Practical use involves checking the context. If copper and AUD are moving together, the move gains credibility. If they diverge, something else is driving the pair.
Data availability is a limit, as is timing. Copper futures trade on specific exchanges with set hours, and the lead-lag relationship may only exist in the overlapping window.
Measure instead of assuming: test correlation of short-term returns at the strategy's horizon, separating by session.
Does copper add any information for AUD scalps in the sessions that matter?
