FX-Commodity Link: AUD-Iron Ore, CAD-Oil, NZD-Dairy Correlations
Tracking the commodity-currency correlations — AUD/USD vs iron ore, USD/CAD vs WTI, NZD vs dairy — and the cross-asset trades they unlock.
The FX-commodity link is one of the most durable cross-asset correlations in markets. Australia exports iron ore and coal to China; the AUD trades as a proxy for both. Canada exports oil; USD/CAD inversely correlates with WTI. New Zealand exports dairy; the NZD moves with global milk futures. Norway exports oil; NOK does too. These aren't theories — they're the actual mechanism by which terms-of-trade shocks transmit to currencies.
This hub aggregates RockstarMarkets coverage of the FX-commodity correlations: when iron ore breaks, how does AUD/USD respond. When WTI moves $5, what happens to USD/CAD. The cross-asset framing helps traders see the next leg of a commodity move in the FX leg first, and vice versa.

Frequently asked
What is a commodity currency?
A currency whose value is materially driven by the country's commodity exports. The classic 'comdolls' are AUD (iron ore, coal), CAD (oil), NZD (dairy, agricultural), NOK (oil) and BRL (iron ore, soybeans). When their export commodity rallies, the currency typically follows.
How tight is the USD/CAD-oil correlation?
Roughly -0.7 to -0.85 on a 60-day rolling basis. A $1 move in WTI typically corresponds to a 30-50 pip move in USD/CAD (in the opposite direction). The correlation breaks down during BoC policy surprises or US fiscal events.
Why does the Australian dollar follow iron ore?
Iron ore is Australia's largest export by value (~25% of total exports), almost entirely sold to China. When iron ore prices rally, Australia's terms-of-trade improve, supporting AUD via higher commodity revenue and stronger domestic GDP expectations. The correlation is roughly +0.6 to +0.75.
Which ETFs give exposure to commodity-currency trades?
Direct currency ETFs: FXA (AUD), FXC (CAD), FXY (JPY for the funding leg). Commodity ETFs to pair: USO/BNO (oil for CAD), JJC (copper for AUD), CORN/SOYB (agriculture for BRL). Trader pairs often use FX spot + commodity futures rather than ETFs for tighter execution.
