AUDUSD is the world's 5th most traded currency pair, accounting for approximately 6% of global forex volume. Unlike EURUSD or GBPUSD, the Aussie dollar has a strong commodity correlation — making it one of the most macro-sensitive pairs to trade and backtest.
Understanding WHY AUDUSD moves (commodities, China, RBA) makes you a better backtester, because you can simulate your strategy across different macro regimes: risk-on bull runs, commodity crashes, and Fed vs RBA divergence periods.
Key AUDUSD Price Drivers
Iron Ore & Copper Prices
Australia's top exports. Rising iron ore → AUD/USD up. A 10% drop in iron ore typically moves AUDUSD 100–300 pips in the same direction.
Chinese Economic Data
China buys 70%+ of Australian iron ore. Weak Chinese PMI → risk-off → AUD/USD falls. Practice how AUDUSD reacted to each Chinese data release in 2022–2024.
RBA Policy
Reserve Bank of Australia rate decisions move AUDUSD significantly. RBA hikes → AUD strengthens. The 2022–2023 RBA hiking cycle is ideal to backtest.
Global Risk Sentiment
AUD is a "risk-on" currency. Stocks rally → AUDUSD often rallies. Recessions/crises → AUDUSD falls sharply. The COVID crash (2020) and 2022 bear market are key periods.
USD Strength (DXY)
The US Dollar Index is inversely correlated with AUDUSD. When DXY rises (Fed hikes), AUDUSD usually falls. The 2022 DXY rally to 20-year highs crushed AUDUSD to 0.62.
US–Australia Rate Differential
When Fed rates > RBA rates, USD is preferred → AUDUSD falls. When RBA leads the Fed in hiking, AUD gets support. Monitor this spread in your backtesting context.

Open FXAbsolute →AUDUSD is underrated as a practice pair and I came to it embarrassingly late. The macro drivers are simpler than EURUSD (iron ore + China GDP vs the full ECB/EU political machine) and the trend moves are longer and cleaner. The 2022 downtrend from 0.76 to 0.62 was driven by a deteriorating China demand story you could track in real time from commodity data. Macro pairs reward curiosity about the world, not just chart reading.
