Commodity Currencies

Commodity currencies are influential in shaping global economies.

These currencies, often also referred to as “resource-based currencies,” derive their value and stability from the exportation of key commodities such as crude oil, gold, copper, and agricultural products.

Typically, nations that have abundant natural resources and large export-oriented economies, such as Australia, Canada, Russia, and several African and South American countries, have currencies that have strong correlations with the fluctuations in global commodity prices.

The concept of commodity currencies isn’t new, but its importance over time has grown due to the increasing interconnectedness of global markets, the rising demand for raw materials, the strategic importance of certain raw materials, and the markets placing more of a premium on strategic non-financial assets.

These currencies serve as an important link between the global demand for commodities, the supply chains of them, and the economic health of resource-rich countries.

We’ll provide an overview of the factors that drive commodity currencies, their influence in international trade and finance, and the risks and opportunities associated with them (e.g., when is it good to buy and sell them?).

Key Takeaways – Commodity Currencies

• Commodity currencies derive some their value from the exportation of key commodities. They may be highly sensitive to fluctuations in commodity prices.
• Understanding the nuances of commodity currencies can help investors/traders identify investment and trading opportunities and policymakers manage risks associated with currency movements.
• Holding any asset denominated in a commodity currency means you’re implicitly exposed to that country’s key commodity, whether you intended to be or not.
• Commodity currencies are impure proxies for the underlying commodity because they also carry interest rate, political, and broader macro risk.
• Commodity currencies vary widely in sensitivity, volatility, and asymmetry, and they correlate heavily during crises, limiting diversification benefits.

Types of Commodity Currencies

Commodity currencies can be categorized based on the type of commodity that dominates the country’s exports:

• Energy-based currencies: e.g., Canadian Dollar (oil and gas)
• Metal-based currencies: e.g., Australian Dollar (iron ore, gold)
• Agricultural-based currencies: e.g., New Zealand Dollar (dairy products)

Why Understanding Commodity Currencies Is Important

Understanding commodity currencies is important for traders because their value closely tracks key commodity prices like oil (CAD, NOK), copper (CLP), and iron ore (AUD).

They offer indirect exposure without trading futures directly. This can be from FX trades themselves or from investments denominated in those currencies (stocks, bonds, real estate, estate).

This linkage drives predictable FX moves from terms-of-trade shifts. This helps with better positioning in macro strategies, hedging commodity risk via spot FX, and anticipating volatility from supply shocks or demand cycles.

For quants, it can sharpen models by incorporating export betas (e.g., CLP’s 50% copper reliance), revealing asymmetries (NOK’s downside oil sensitivity), and boosting edge in cross-asset arbitrage type strategies.

Even if you’re not a currency trader…

Let’s say you’re an American and you own a Canadian bond in a services company.

You don’t just own the bond; you own CAD currency.

If oil prices fall, that can negatively affect your investment or trade, even if the services company has nothing to do with oil.

Commodity Currencies List

Commodity currencies are those of countries whose economies are heavily dependent on the export of natural resources.

Some common examples of commodity currencies include:

• Australian Dollar (AUD)
• Canadian Dollar (CAD)
• New Zealand Dollar (NZD)
• Norwegian Krone (NOK)
• Russian Ruble (RUB)
• Brazilian Real (BRL)
• South African Rand (ZAR)
• Chilean Peso (CLP)

What are the main exports of each commodity currency?

• AUD – Metals (iron ore), coal, LNG. There’s also some gold exposure (around 5-6% of Australia’s total exports).
• CAD – Crude oil, refined products. Canada is known for its broader energy complex.
• NZD – Dairy (milk powder), meat, soft commodities more broadly
• NOK – Crude oil and natural gas (North Sea / Brent complex)
• RUB – Crude oil and products (Urals/Brent-linked), gas
• BRL – Iron ore, soybeans and broader ags (sugar, coffee, meat)
• ZAR – Gold, platinum group metals (e.g., platinum, palladium), some coal
• CLP – Copper, plus some other base metals

Increases in the value of these commodities are typically positive for the currency vs. USD and negative for the corresponding USD/FX pair.

We’ll go through each currency one by one.

We’ll look at the main commodities, typical sign, and the intuition as to why theyy move accordingly.

AUD (Australian dollar)

Main commodities

Iron ore, coal, LNG, gold.

Typical sign

Iron ore ↑, coal ↑, LNG ↑ → AUD tends to appreciate (AUD/USD ↑, USD/AUD ↓).​

Gold ↑ often coincides with AUD strength vs. USD as well.​

Intuition

Greater than 50% of Aussie exports are resource commodities.

So terms-of-trade improvements re-rate the AUD.​

CAD (Canadian dollar)

Main commodities

Crude oil (WTI/Western Canada Select), refined products, natural gas.

Typical sign

Oil ↑ → CAD strengthens

So, USD/CAD tends to fall, with stronger moves the larger the oil move.

If we look at the relevant ETFs (FXC (a CAD ETF) and GSG (an oil ETF)), they show a +0.55 correlation at the monthly level.

Intuition

Canada is a large net oil exporter to the US, so oil is a first-order driver of CAD in most macro narratives.​

NZD (New Zealand dollar)

Main commodities

Dairy (whole milk powder, butter, cheese), meat, logs.

Typical sign

Dairy price indices (GDT auction, etc.) ↑ → NZD tends to appreciate vs USD.

Intuition

Dairy dominates New Zealand’s export basket, so improved milk prices support the NZD terms of trade.​

NOK (Norwegian krone)

Main commodities

Crude oil (Brent-linked), natural gas.

Typical sign

Oil ↑ → NOK tends to strengthen (USD/NOK ↓, EUR/NOK ↓).

Relationship is asymmetric: NOK often reacts more to oil down moves than up moves.​

Why?

Because falls in oil prices threaten Norway’s trade balance and fiscal outlook (e.g., cash flows, growth expectations). Moreover, oil price gains can be partly saved in its sovereign wealth fund.

Accordingly, markets mark down NOK more aggressively on oil declines than they bid it up on rallies.

Intuition

Hydrocarbon revenues and SWF flows tie NOK closely to the oil/gas cycle.​

RUB (Russian ruble)

Main commodities

Crude oil, refined products, natural gas.

Typical sign

Oil ↑ → RUB tends to appreciate (USD/RUB ↓)

Intuition

Russian fiscal and external balances are heavily oil-linked.

RUB/USD and oil share a long-run relationship, as Russia’s national income is heavily dependent on it.

BRL (Brazilian real)

Main commodities

Iron ore, soybeans, plus other softs ags (corn, sugar, coffee) and some oil.

Typical sign

Iron ore ↑, soybeans ↑ → BRL tends to strengthen

USD/BRL often trades as a proxy for the Brazil ToT cycle.

Intuition

Iron ore and soy together can exceed 30% of Brazil’s exports.

So their price cycle is a major BRL driver.​

ZAR (South African rand)

Main commodities

Gold, platinum group metals (platinum, palladium, rhodium), coal.

Typical sign

Gold/PGMs ↑ → ZAR tends to appreciate.

USD/ZAR often trades as “EM metals beta.”

Intuition

South Africa is a key producer of gold and PGMs.

It’s considered the most mining-rich country in the world.

So metal price cycles influence the ZAR alongside EM risk sentiment.

CLP (Chilean peso)

Main commodities

Copper (primary).

Some other base metals, as well, like molybdenum and iron ore.

But copper is about 50% of Chile’s total exports.

Typical sign

Copper ↑ → CLP tends to appreciate.

USD/CLP is typically inversely correlated with copper.

Intuition

Copper dominates Chile’s export revenue.

Historically, copper and USD/CLP show an inverse correlation.​

FX here is quoted vs. USD. So “+” means currency tends to strengthen when the commodity rises:

Commodity Currency vs. Term Currency

A commodity currency is one that is influenced by the value of a specific commodity, while a term currency refers to the base currency in a currency pair.

In the foreign exchange market, major currencies like the US dollar, euro, yen, and British pound are usually considered “term currencies.”

They are global reserve currencies (to varying degrees) and often act as reference currencies in FX pairs. The USD is the most popular, followed by the EUR.

Commodity Prices and Currency Movements

Commodity currencies tend to be sensitive to fluctuations in commodity prices.

How sensitive depends on the exact nature of their economies.

As commodity prices increase, the value of the exporting country’s currency also tends to rise due to higher demand for their exports.

Conversely, when commodity prices fall, the currency’s value may decline as export revenues decrease.

In a separate article, we looked at the influence of a country’s current and capital accounts on the value of its currency.

Commodity-Backed Currency

A commodity-backed currency is not the same thing as a commodity currency.

A commodity-backed currency is a currency that is directly pegged to the value of a specific commodity, such as gold or oil.

(For example, the USD was a commodity-backed currency under the Bretton Woods system from 1944 to 1971. It’s been a fiat money system since.)

This type of currency is different from fiat money, which has no intrinsic value and is not backed by a physical commodity.

In a fiat money system, money creation is simply based on the demand for it so we don’t have to physically barter.

Commodity Currencies and the Real Exchange Rate

The real exchange rate measures the value of a currency relative to another, adjusted for inflation.

Commodity currencies naturally have a dependence on commodity prices, which influences inflationary pressures.

Commodity Currencies and Equity Flows

Investors/traders often consider commodity currencies when making decisions in the equity market.

A strong commodity currency can be an indicator of a healthy economy, leading to increased investment in equities within the country.

When you own a stock, you own a pile of that currency.

So if you were to own a Canadian stock as a non-CAD investor with no FX hedge, you’re also making a bet on oil prices considering Canada is an oil exporter and that influences the value of its currency.

A financial asset in a foreign currency is the returns + currency.

If you’re making 7% per year on the financial asset, but the currency is falling relative to your domestic currency by more than 7% per year, you’re losing money.

A weak commodity currency may signal economic difficulties, prompting investors to divest from the country’s equity markets.

Commodity Currencies Basket

A commodity currencies basket is a collection of currencies from countries that are major commodity exporters.

This basket is often used as a benchmark to track the performance of commodity currencies or as an investment tool to gain exposure to the commodity market.

For example, in an inflationary or stagflationary environment, more traders/investors will want access to this commodity currencies basket as a way to protect their portfolios from inflation.

G10 Commodity Currencies

G10 commodity currencies are the currencies of the Group of Ten countries, which are major advanced economies.

Among these, the Canadian Dollar, Australian Dollar, and Norwegian Krone are considered commodity currencies due to their reliance on natural resource exports.

Commodity Currencies in Emerging Markets

Emerging market commodity currencies include those from countries like Brazil, Russia, South Africa, and Chile.

These currencies are often more volatile than those of developed economies due to various factors, including political instability, lower liquidity, and weaker economic fundamentals.

Safe-Haven Commodity Currencies

Safe-haven commodity currencies are those that investors turn to in times of wider-than-normal market expectations or market volatility.

While traditional safe-haven currencies include the US Dollar, Swiss Franc, and Japanese Yen, some investors also consider the Canadian Dollar and Australian Dollar as safe-haven options due to their strong economies and stable political systems.

Climate Risk and Commodity Currencies

Climate risk is an emerging concern for commodity currencies, as the effects of climate change can have a significant impact on the value of these currencies.

Commodity currencies, such as the Australian dollar, the Canadian dollar, and the New Zealand dollar, are heavily reliant on the prices of commodities such as oil, gas, and minerals for their value.

If the production and export of these commodities are disrupted due to climate policy, it can cause a decline in their prices. This can lead to a decrease in the value of commodity currencies, as the demand for these currencies falls.

Governments and central banks of commodity currency countries are also taking steps to address these risks. For example, the Bank of Canada has included climate risk as one of the key risks to financial stability in its annual report, and the Reserve Bank of New Zealand has incorporated climate risks into its stress testing framework.

FAQs – Commodity Currencies

What are some examples of commodity currencies?

Some examples of commodity currencies include the Australian Dollar (AUD), Canadian Dollar (CAD), New Zealand Dollar (NZD), Norwegian Krone (NOK), Russian Ruble (RUB), Brazilian Real (BRL), South African Rand (ZAR), and Chilean Peso (CLP).

Is CAD a commodity currency?

Yes, the Canadian Dollar (CAD) is considered a commodity currency due to Canada’s economy being heavily dependent on the export of natural resources, particularly oil and gas.

What are commodity currency pairs?

Commodity currency pairs are forex pairs that involve at least one commodity currency.

Some common commodity currency pairs include:

• AUD/USD (Australian Dollar/US Dollar)
• USD/CAD (US Dollar/Canadian Dollar)
• NZD/USD (New Zealand Dollar/US Dollar)
• USD/NOK (US Dollar/Norwegian Krone)
• USD/RUB (US Dollar/Russian Ruble)
• USD/BRL (US Dollar/Brazilian Real)
• USD/ZAR (US Dollar/South African Rand)
• USD/CLP (US Dollar/Chilean Peso)

Does a commodity currency mean a country exports commodities?

Yes, a commodity currency generally refers to the currency of a country that relies heavily on the export of commodities, such as energy resources, metals, or agricultural products.

The value of these currencies tends to be closely tied to fluctuations in commodity prices, which can affect their exchange rates.

Are some commodity currencies stronger than others?

Commodity currencies vary in strength based on commodity exposure, export concentration (higher % to one commodity = stronger beta), diversification, policy, and other factors.

CLP, NOK, and CAD typically show the strongest betas to their key commodities.

AUD and NZD are somewhat less pure due to broader baskets or policy offsets.

Of course, things also change over time. RUB is oil-dominant, but geopolitics have dominated in recent years.

ZAR’s movement is 15-20% PGMs and gold (with variance). But this is weakened by EM carry (e.g., long ZAR, short lower-interest funding currency) and risk flows.

Why are commodity currencies important if I don’t trade them?

Let’s say you’re a German holding a Chilean corporate bond in a tech firm. You don’t just own the bond itself, but are exposed to the CLP currency.

If copper prices fall a lot (50% of Chile’s exports), the peso weakens sharply. This hit the bond’s EUR value even if the tech firm has zero ties to mining.

How do commodity currencies behave during recessions vs. expansions?

Commodity currencies tend to strengthen during global expansions. Rising demand pushes commodity prices higher. And capital flows toward riskier assets with prospective higher yields and growth.

During recessions, the reverse happens.

Falling commodity demand, collapsing prices, and a flight to safe-haven currencies (USD, JPY, CHF) typically cause commodity currencies to weaken.

Sometimes this happens sharply and quickly, as some commodity currencies are prone to hot flows.

What’s the difference between trading the commodity itself and trading a relevant commodity currency?

Trading the commodity (via futures or ETFs) gives you direct price exposure to that resource.

Trading the commodity currency is impure exposure because it adds layers.

With the currency, you’re also exposed to the country’s interest rates, monetary policy, political risk, trade balance, and other FX-related factors.

For example, buying CAD gives you some level of oil exposure. But it also gives you Bank of Canada rate expectations and Canadian economic data. So oil can rise and CAD can fall if the other factors are more than enough of an offset.

Commodity futures offer more pure and more leveraged exposure to the resource.

So overall, commodity currencies will give you a blended macro trade. The commodity is one input among several.

So, if you want the commodity, it’s generally best to buy the commodity rather than CAD or an oil-related currency.

And while we’re on the subject of the CAD, let’s not overemphasize oil as a driver. Measured by GDP, oil and gas are roughly 3-4% of Canada’s economy directly, and about 6-7% if you include broader indirect and supply-chain effects.

Do commodity currencies move in real time with commodity prices, or is there a lag?

Major moves in commodity prices tend to transmit quickly to currencies, usually feeding in instantly with the influences algorithms pick up right away.

Smaller or slower price shifts can take days or weeks to fully integrate into the market, especially when central bank policy or risk sentiment is pulling in the opposite direction of the commodity move.

This is when there’s a correlation breakdown.

How do interest rate differentials interact with commodity price movements for these currencies?

Interest rate differentials and commodity prices often reinforce each other.

When commodity prices rise, exporting countries see stronger growth and inflation, all else equal. This can prompt central banks to hike rates.

Higher rates attract carry trade inflows (i.e., yield seekers), adding further currency strength on top of the commodity tailwind.

When the two forces conflict (rising commodity prices but dovish central bank, or falling prices but hawkish policy), the currency can stall or chop sideways.

Can I hedge commodity exposure through commodity currencies instead of futures?

Yes, but it’s just important to be aware that it’s an imprecise hedge.

Commodity currencies track commodity prices loosely, not one-for-one.

As mentioned, you’re also taking on interest rate, political, and broader FX risk.

For approximate or portfolio-level hedging it can work if implemented well.

For tight, specific hedging of a known commodity exposure, futures or options on the commodity itself are more reliable.

What happens to commodity currencies during a USD strength cycle?

Commodity currencies generally weaken during USD strength cycles.

This is because rising dollar demand suppresses commodity prices and pulls capital away from riskier assets – all else equal.

Are commodity currencies more volatile than non-commodity currencies?

Generally, yes.

Commodity currencies carry an extra source of volatility from swings in underlying commodity prices. That’s on top of the usual macro and rate drivers that affect all currencies.

Pairs like USD/ZAR and USD/BRL can be a lot more volatile than, say, EUR/USD or USD/CHF.

That said, not all commodity currencies are equally volatile.

AUD and CAD tend to be moderate, while emerging market commodity currencies (BRL, ZAR, RUB) carry additional political and liquidity risk that amplifies moves.

How correlated are commodity currencies with each other?

Moderately to highly correlated during risk-on/risk-off episodes. But the correlation breaks down in quieter markets.

When global risk appetite shifts hard in either direction, commodity currencies tend to move as a group because they share exposure to the same macro forces: global growth expectations, USD direction, and broad commodity demand.

Outside of those regime shifts, individual drivers take over. CAD might diverge from AUD if oil is rallying while iron ore is flat.

NOK can decouple from ZAR if European gas dynamics differ from South African mining output.

Correlations also rise during crises (generally when you want diversifying return sources the most) and compress during calm periods. All of this matters for portfolio construction.

Holding multiple commodity currencies doesn’t necessarily diversify that much.

Diversification is more likely from building diversified subportfolios in different currencies, in an approach we describe more here.

Can a country stop being a commodity currency?

In theory, yes. But it’s rare and slow to diversify an economy to the point where the commodity revenue translates into lots of investment that creates non-commodity revenue.

If a country diversifies its export base enough that commodities no longer dominate trade revenue, then the currency’s sensitivity to commodity prices gradually weakens.

Norway is the closest example: oil still matters, but the massive sovereign wealth fund, a large services sector, and active fiscal management have partially dampened the krone’s crude oil beta compared to decades ago.

Full decoupling would require commodities to drop well below 20-30% of export revenue and for other sectors to absorb the foreign exchange inflows.

(What’s the math?

Commodity currency beta = (Commodity Export Share x Terms-of-Trade Elasticity x Pass-Through Coefficient).

If export share falls below ~20-30%, beta -> insignificant (e.g., <0.2 corr threshold). Diversification math: sustained non-commodity FX inflows must exceed commodity swings. Norway case: oil ~25% exports -> SWF buffers ~40% GDP -> services absorb rest -> observed NOK/oil corr dropped ~0.7 (1990s) to ~0.4 (recent).)

Saudi Arabia is also notably trying this diversification path.

But most commodity-dependent economies find this structurally difficult because commodity wealth itself crowds out other industries.

What is Dutch Disease? How does the Dutch Disease concept relate to commodity currencies?

Dutch Disease describes what happens when a resource boom strengthens a country’s currency so much that it makes other export sectors (manufacturing, agriculture, services) uncompetitive internationally – i.e., the currency appreciates and makes its goods more expensive on the international market.

The name comes from the Netherlands after its 1960s natural gas discovery.

For commodity currencies, Dutch Disease is a structural risk.

A sustained commodity rally drives up the currency, which hollows out non-commodity industries over time.

This deepens the economy’s dependence on the resource, making the currency even more sensitive to commodity price swings in the future.

It creates a feedback loop: commodity strength leads to currency strength, which kills diversification, which increases future commodity dependence.

Do commodity currencies tend to have higher inflation than non-commodity currencies?

Not as a universal rule, but there’s a pattern.

Commodity booms inject large amounts of foreign revenue into these economies, which can drive domestic demand and push prices higher, especially in housing, services, and wages.

Emerging market commodity currencies (BRL, ZAR) tend to run higher structural inflation due to:

• weaker institutional frameworks
• less credible central banks, and
• certain forms of supply-side bottlenecks (inadequate infrastructure, energy shortages, labor market rigidities, regulatory barriers that block investment and steepen supply curves, land access issues)

Developed commodity economies (Australia, Canada, Norway) generally keep inflation closer to G7 norms (2-3% annually) because their central banks are credible and proactive.

Overall, the key variable is institutional quality, rather than commodity exposure alone.

How do sovereign wealth funds (like Norway’s) affect a commodity currency’s behavior?

Sovereign wealth funds serve as a buffer between commodity revenue and the domestic economy.

Norway’s Government Pension Fund Global is the textbook example.

Instead of flooding the economy with oil revenue (which would strengthen the krone and risk triggering Dutch Disease), the fund invests almost entirely abroad.

This recycles commodity income out of the domestic currency. As such, it dampens appreciation pressure during booms and provides a fiscal cushion during busts.

The effect is a smoother, less volatile currency path than you’d expect given Norway’s oil dependence.

Countries without this mechanism (or with poorly managed funds) see their currencies track commodity prices much more directly.

Conclusion

Commodity currencies reflect the importance of natural resources and the countries that produce and export them.

These currencies tend to be highly sensitive to commodity price fluctuations, so they can provide insights into the health of certain forms of economic demand and the demand for inputs into industrial and essential goods.

Investors, traders, and policymakers should be aware of the nuances of commodity currencies. Consider their correlation with commodity prices, their role in forex markets, and their impact on equity flows and real exchange rates.

Understanding the relationship between climate risk and commodity currencies is also becoming increasingly important as climate change and climate concerns influence policy and demand.

Even for traders not involved in commodity currency markets, they can gain a deeper understanding of global economic trends, identify opportunities within or outside of the FX markets, and manage the risks associated with investments or currency movements.
