Terms of Trade Signal a Three-Way Split in Commodity Bloc Currencies
The commodity currency complex is exhibiting an increasingly fractured profile this session, with AUD/USD trading at 0.697 (-0.35%), USD/CAD at 1.4105 (+0.13%), and NZD/USD at 0.578 (-0.32%). While all three economies share sensitivity to global demand and commodity price fluctuations, the underlying terms of trade dynamics are diverging in ways that create distinct trading opportunities. The simultaneous decline in gold (-1.23% to 4021.73 USD/oz) and crude oil (WTI -1.46% to 81.4 USD/bbl, Brent -1.75% to 86.81 USD/bbl) is weighing broadly, but the relative performance of each currency reveals nuanced exposure to specific commodity baskets and evolving domestic policy landscapes.
AUD/USD: Iron Ore and Gold Headwinds Test Key Support
The Australian dollar is underperforming this session, with AUD/USD slipping toward the psychologically significant 0.6950 handle. The dual pressure from falling gold prices and a broader risk-off tone in commodity markets is particularly acute for Australia, given the Reserve Bank of Australia’s ongoing sensitivity to terms of trade shifts. Gold’s decline to 4021.73 USD/oz, while still elevated by historical standards, removes a key support pillar for the Aussie, especially as the precious metal’s correlation with AUD has strengthened over the past quarter.
From a technical perspective, AUD/USD is testing the 0.6950-0.6970 demand zone that has held since mid-July. A break below 0.6950 opens the path toward 0.6900, with the next major support at 0.6850 — the June low. On the upside, resistance sits at 0.7020 (the 50-day moving average) and then 0.7080, which marks the July high. The RBA’s recent cautious tone on inflation, combined with China’s uneven recovery data, continues to cap any sustained upside in the Aussie.
Scenario analysis:
- Bullish catalyst: A stabilization in iron ore prices and a break above 0.7020 could trigger a recovery toward 0.7080, particularly if risk appetite improves.
- Bearish catalyst: Continued gold weakness below 4000 USD/oz and a break of 0.6950 would likely accelerate selling toward 0.6850.
USD/CAD: Oil’s Decline Meets Domestic Resilience
The Canadian dollar is showing relative resilience against its commodity peers, with USD/CAD grinding higher to 1.4105 but failing to break decisively above the 1.4120 resistance level. WTI crude’s decline to 81.4 USD/bbl and Brent’s slide to 86.81 USD/bbl are clearly negative for Canada’s export revenues, yet the loonie is finding support from a relatively hawkish Bank of Canada stance and robust domestic employment data.
The USD/CAD pair is currently trapped between the 1.4050 support and 1.4120 resistance, with the broader trend still favoring the upside given the divergence between the Federal Reserve’s tightening cycle and the BoC’s more measured approach. However, the 1.4120 level has proven sticky, representing the July 24 high and a key pivot point for the pair.
Key levels to watch:
- Support: 1.4050 (20-day moving average), 1.3980 (July low)
- Resistance: 1.4120 (session high), 1.4180 (June high)
The oil-CAD correlation has weakened somewhat in recent weeks, as the market prices in Canada’s diversified export base and the BoC’s willingness to hike further if inflation proves sticky. A break above 1.4120 would target 1.4180, while a move below 1.4050 could see a retest of 1.3980.
NZD/USD: Dairy and Gold Exposure Creates a Double Drag
The New Zealand dollar is the weakest link in the commodity FX complex this session, with NZD/USD sliding to 0.578 (-0.32%) and approaching the critical 0.5750 support level. The Kiwi’s vulnerability stems from its dual exposure to falling gold prices and a softening dairy auction outlook. While dairy prices have shown some stability in recent Global Dairy Trade auctions, the broader risk-off tone and China’s slowing import demand continue to weigh heavily on New Zealand’s terms of trade.
NZD/USD is testing the lower end of its recent 0.5750-0.5900 range, with the 0.5750 level representing the July 19 low and a key support zone. A break below this level would open the door to a move toward 0.5700, the lowest since October 2022. Resistance sits at 0.5850 (the 50-day moving average) and then 0.5900, which has capped all upside attempts since early July.
The Reserve Bank of New Zealand’s recent dovish shift, combined with the market pricing in rate cuts by early 2027, is exacerbating the Kiwi’s weakness. Unlike the RBA and BoC, the RBNZ appears more willing to ease policy as inflation moderates, creating a fundamental headwind for NZD.
Cross-Asset Links and the Risk Rotation Framework
The broader risk rotation is playing a significant role in today’s commodity FX dynamics. The USD/JPY move to 163.86 (+0.15%) reflects persistent yen weakness, which is amplifying the dollar’s strength against commodity currencies. Meanwhile, the decline in natural gas (-2.28% to 2.7 USD/MMBtu) adds to the deflationary narrative that is weighing on all three commodity currencies.
The EUR/USD stability at 1.139 (-0.05%) suggests that the dollar’s strength is not universal but rather concentrated against commodity-sensitive currencies. This selective dollar strength reinforces the terms of trade divergence thesis — the USD is gaining where commodity prices are falling, but not against currencies with their own domestic policy support.
Looking ahead, the key catalyst for a reversal in commodity FX weakness would be a stabilization in gold above 4000 USD/oz and crude oil above 80 USD/bbl for WTI. Until then, the path of least resistance remains lower for AUD, NZD, and to a lesser extent, CAD.

Desk View
- AUD/USD vulnerable below 0.6950: Gold’s decline to 4021.73 USD/oz and China growth concerns keep the Aussie under pressure; look for a break of 0.6950 to accelerate selling toward 0.6850.
- CAD shows relative strength despite oil weakness: USD/CAD stuck between 1.4050-1.4120; a sustained break above 1.4120 needed to confirm further upside toward 1.4180.
- NZD/USD the weakest link: Testing 0.5750 support with a dovish RBNZ backdrop; a break below opens the path to 0.5700.
- Cross-asset focus: Watch gold at 4000 USD/oz and WTI at 80 USD/bbl as key thresholds for a potential reversal in commodity FX weakness.
