Frequently Asked Questions
What makes AUD/USD a "commodity currency" pair?
Australia is the world's largest iron ore exporter, a top-three coal exporter, and a major LNG supplier. AUD/USD is tightly correlated with iron ore and copper futures — when Chinese industrial data is strong and commodity prices rise, AUD rallies against USD.
How does China affect AUD/USD?
China buys roughly 30% of Australian exports. Chinese manufacturing PMIs, fixed-asset investment data, and property-sector news all move AUD directly. A Chinese stimulus announcement routinely produces a 1%+ AUD rally; a property-sector default scare produces the opposite.
When does the RBA meet?
The Reserve Bank of Australia meets the first Tuesday of each month (except January). Rate decisions are announced at 04:30 UTC, followed by the statement. The Governor's press conference (typically same day) is another major catalyst.
Why is AUD considered a "risk-on" currency?
AUD has one of the highest positive correlations with global equity indices. When risk appetite improves and equities rally, AUD typically rallies against safe-havens like JPY and CHF. When VIX spikes, AUD is usually among the worst-performing G10 currencies.
What is the tightest spread time for AUD/USD?
Sydney–Tokyo session (22:00–08:00 UTC) has the deepest AUD liquidity. Spreads widen during the New York afternoon and around Asian holidays. For retail execution, the London morning (07:00–10:00 UTC) offers good combined liquidity.
