Intermarket Relationships in Commodities
A deep-dive into how gold, oil, agricultural markets and key commodity currencies (AUD, CAD, BRL) interact within the global macro system.
What this article helps you do
- Think in systems (not isolated charts).
- Understand the USD as the center of commodity pricing.
- Use real yields as the professional layer for gold.
- Connect oil ↔ CAD and agriculture ↔ BRL via terms of trade.
- Translate intermarket logic into context (not signals).
Trader’s framing
Intermarket analysis does not predict markets — it explains them.
Use these relationships to improve regime awareness (risk-on vs. risk-off) and to validate whether moves “make sense” within the broader macro environment.
The Commodity Intermarket System
Use the map as a structural overview. Relationships are regime-dependent and can strengthen or weaken with shifts in global liquidity and risk sentiment.
1) The US Dollar: The Center of the Commodity System
Most global commodities are priced in USD. This makes the dollar a system-wide transmission mechanism for global liquidity and purchasing power.
Supply shocks can overwhelm everything, but in many macro regimes a rising USD creates headwinds for commodities, while a weakening USD provides structural support — especially via emerging market demand.
2) Gold and the US Dollar
Gold is priced in USD, so a weaker dollar often supports gold via purchasing power effects for non-USD buyers. However, crisis regimes can produce a “safe haven double bid” (USD and gold rising together).
Important exception
During stress, USD and gold can rise together: USD as liquidity/funding demand, gold as monetary insurance.
3) Gold and Real Yields (The Professional Layer)
Real yields (inflation-adjusted rates) represent the opportunity cost of holding a non-yielding asset like gold. This is one of the most structurally important relationships for gold over medium to long timeframes.
Separating the “USD story” from the “real yield story” often resolves confusion when correlations appear to break. Sometimes gold reacts more to rates than to the dollar.
Key Relationships (Fast Mental Models)
These are structural tendencies. Use them to build context — then execute with price structure and risk management.
Energy Oil ↔ CAD
Higher oil prices can improve Canada’s terms of trade and support CAD. Oil also impacts inflation expectations (a key link into rates).
Gold exporter Gold ↔ AUD
Australia is a major commodity exporter and gold producer. In risk-on regimes, commodity strength can support AUD. In risk-off regimes, AUD may weaken even if gold holds firm.
Agriculture Agriculture ↔ BRL
Brazil is a global agricultural powerhouse (sugar, coffee, soybeans). Strong ag prices can support BRL via trade flows, but EM FX remains sensitive to USD strength and global liquidity.
System USD ↔ Broad Commodities
The USD acts like “gravity” for global commodity pricing. It won’t override supply shocks, but it often defines the wind at your back (or in your face) across commodity cycles.
Tip: If you trade commodities, this grid is your “sanity check”. If price action contradicts the macro backdrop, ask why — don’t force a trade.
Intermarket Chains (The Most Useful Way to Think)
Single correlations are fragile. Chains are more robust because they reflect plausible cause-and-effect sequences.
Chain Energy → Rates → Gold
Oil ↑ → Inflation expectations ↑ → Real yields adjust → Gold reacts
Energy is often the fastest inflation channel. That’s why oil belongs in a gold framework even if you never trade oil.
Chain Dollar Weakness → Commodities
USD ↓ → Broad commodities ↑ → Exporters supported
A softer USD can support demand, improve terms of trade, and stabilize exporter currencies — especially in risk-on regimes.
Chain Agriculture → BRL (with EM caveat)
Sugar / Soybeans ↑ → BRL supported — unless USD strength dominates
The caveat matters. BRL can weaken even with strong ag prices if global liquidity tightens or risk-off accelerates.
Chain Stress Regime
Risk-Off ↑ → USD ↑ → EM FX pressure ↓ → Gold outperforms
This is where gold tends to outperform higher-beta commodities and commodity currencies.
