How commodity cycles affect the Canadian dollar and TSX

The Canadian dollar is often described as a commodity-linked currency because Canada exports significant amounts of energy, metals, agricultural products, forestry products, and other natural resources. Commodity prices can therefore affect trade flows and economic activity.

However, the relationship extends beyond oil prices. The Canadian dollar can also respond to interest-rate differentials, movements in the U.S. dollar, domestic economic conditions, and global market sentiment.

For Canadian portfolios, these relationships can affect the Canadian-dollar value of foreign assets and create indirect commodity exposure through Canadian companies and equity indexes.

What does Canadian dollar-commodity correlation mean?

Correlation measures how closely two variables have moved in relation to each other over a defined period. A positive correlation means they have generally moved in the same direction, while a negative correlation means they have moved in opposite directions. A low correlation can indicate a weaker or inconsistent relationship.

Correlation does not establish that one variable caused another to move. Both may respond to a third factor, such as global economic activity or U.S. dollar movements.

Results can also vary based on the commodity, time period, data frequency, and whether price levels or percentage returns are measured.

Correlation: A statistical measure showing how closely two variables have moved together over a specific period. A historical correlation does not establish causation or predict future movements.

As a result, the Canadian dollar's relationship with commodities can vary across different commodities and periods rather than following a fixed pattern.

Why commodity prices can affect the Canadian dollar

Canada’s role as a commodity exporter

Canada's export base includes energy products, metals and minerals, agricultural products, and forestry products. Global Affairs Canada, drawing on Statistics Canada data (opens in a new tab), reported approximately $779 billion in total merchandise exports in 2025. (opens in a new tab) Energy products accounted for about $189 billion, while metal ores and non-metallic minerals represented approximately $29.6 billion. Farm, fishing, and intermediate food products accounted for about $58.4 billion, and forestry products and building and packaging materials represented approximately $44.5 billion.

These figures illustrate the breadth of Canada's resource exports. Changes in commodity prices can affect the value of those exports, company revenues, investment activity, and income generated in resource-producing regions.

Trade flows and demand for Canadian dollars

International buyers purchasing Canadian goods can create demand for Canadian currency, although the connection can involve several layers. Export contracts may be denominated in U.S. dollars or other currencies, while companies can use currency hedging and other financial arrangements.

As a result, a higher commodity price does not necessarily translate into an equivalent increase in demand for Canadian dollars. Trade flows can contribute to currency movements alongside other financial and economic factors.

Economic growth and interest-rate expectations

Changes in commodity revenues can affect economic activity, provincial revenues, and business investment. They can also influence inflation conditions and market expectations around interest rates.

These effects can reach the Canadian dollar indirectly. At the same time, domestic economic conditions can influence the currency independently of commodity prices. The resulting relationship can therefore vary depending on the broader economic environment.

Is the Canadian dollar mainly correlated with oil?

Oil has received considerable attention in discussions about the Canadian dollar because energy exports represent a substantial portion of Canada's merchandise exports. However, the Canadian economy also has exposure to natural gas, base metals, precious metals, agricultural commodities, and forestry products.

The Bank of Canada's Commodity Price Index (opens in a new tab), for example, covers 26 commodities produced in Canada and sold in world financial markets. The Bank of Canada’s components include energy products such as oil and natural gas, as well as non-energy commodities.

Different commodities can have different relationships with the Canadian dollar depending on their importance to Canadian exports, global demand, price volatility, and regional pricing. Transportation infrastructure and supply constraints can also affect how commodity prices translate into Canadian economic activity.

Movements in the U.S. dollar can add another layer. Since many internationally traded commodities are priced in U.S. dollars, changes in the U.S. currency can affect both commodity prices and the U.S. dollar/Canadian dollar exchange rate.

Lower or higher oil prices have historically been associated with movements in the Canadian dollar during some periods, but that relationship has varied and should not be treated as a fixed rule.

Why the relationship changes over time

Commodity cycles

Commodity markets can move through longer periods of changing demand, supply, investment, and pricing. These cycles can influence the importance of resource exports within the Canadian economy.

The relationship between commodities and the Canadian dollar can therefore strengthen or weaken as the composition and importance of different commodity markets changes.

The U.S. dollar, CAD/USD exchange rate, and global risk sentiment

Many commodities trade internationally in U.S. dollars. A broad change in the U.S. dollar can therefore affect commodity prices and the CAD/USD exchange rate at the same time.

Market stress can add another influence. During periods of heightened uncertainty, global capital flows and demand for currencies perceived as more defensive can affect exchange rates independently of commodity prices. 

Interest-rate differentials and domestic conditions

Differences between Canadian and U.S. interest rates can affect currency demand. Other factors can include Canadian economic growth, inflation, employment conditions, fiscal developments, capital flows, and global trade conditions.

These variables can interact with commodity prices rather than operating separately. Consequently, the Canadian dollar can respond to several overlapping forces at the same time, resulting in either a stronger Canadian dollar or a weaker Canadian dollar.

What TSX sector weights reveal about commodity exposure

The Canadian equity market provides another connection between commodities and portfolios. The S&P/TSX Composite Index contains companies across multiple sectors, with the energy sector and materials sector representing meaningful portions of the index.

Energy and materials in the Canadian market

As of August 13 2026, the S&P/TSX Composite Index (opens in a new tab) had sector weights of 36.1% for financials, 17.4% for energy, and 15.6% for materials. Industrials accounted for 10.5%, while information technology represented 7.2%. The figures come from S&P Dow Jones Indices and can change as market values and index constituents change.

The figures demonstrate that the TSX cannot be viewed solely through a commodity lens. Financials represent the largest sector, while industrials, technology, utilities, consumer sectors, and other major industries also contribute to the index.

Overlapping currency and equity exposure

A Canadian portfolio can contain several forms of commodity sensitivity. These can include direct commodity holdings, energy and materials companies, broad Canadian equity funds, and companies whose revenues depend on commodity demand.

Currency exposure can add another layer. For example, the Canadian-dollar value of foreign assets can change when the Canadian dollar moves against the foreign currency, even when the underlying foreign asset price does not change.

These exposures do not move identically. A mining company, an energy producer, a Canadian bank, and a foreign equity can respond differently to the same commodity-price movement.

Reviewing these exposures together can provide a clearer picture of how a portfolio has historically responded to changes in commodity markets and the Canadian dollar.

Understanding the relationship between commodities and the Canadian dollar

The relationship between commodity prices and the Canadian dollar can strengthen, weaken, or diverge depending on broader economic and market conditions.

When commodity and CAD movements align

Commodity prices and the Canadian dollar can sometimes move in the same general direction. This can occur when changes in commodity markets affect Canada's export revenues, economic activity, business investment, and international trade flows.

The relationship can be more noticeable when export prices for resources represent an important influence on Canadian economic conditions. However, other factors can affect the Canadian dollar at the same time, making it difficult to attribute currency movements to commodity prices alone.

When commodity and CAD movements diverge

Commodity prices and the Canadian dollar can also move in different directions. Factors such as changes in the U.S. dollar, interest-rate differentials, global market sentiment, capital flows, and domestic economic conditions can influence the currency independently of commodity prices.

As a result, a change in commodity prices does not necessarily correspond with a similar change in the Canadian dollar.

What the relationship demonstrates

The relationship between commodity prices and the Canadian dollar can vary over time. Commodity prices can be an important influence without being the sole driver of currency movements.

How commodity exposure can appear in Canadian equity indexes

Portfolio exposure can be assessed across several overlapping areas, including Canadian equities, foreign holdings, commodity-sensitive sectors, and companies with significant resource-related revenues.

The effect of a Canadian-dollar movement can differ depending on the currency of an underlying asset. Changes in CAD/USD, for example, can alter the Canadian-dollar value of a U.S. dollar asset even when the asset's local-currency price remains unchanged.

Canadian equities can also have indirect commodity exposure through company revenues, input costs, capital spending, and economic activity. The sensitivity of individual companies can differ from that of the broader TSX because sector composition, business models, and geographic revenue sources vary.

Conclusion: understanding commodity exposure and the Canadian dollar

The Canadian dollar can have a meaningful relationship with commodity prices, including energy prices, because resource exports are an important part of Canada's economy and trade. However, the relationship can vary by commodity, time period, and broader economic conditions. Oil can be an important influence, while natural gas, metals, agricultural products, and other resources can also contribute.

The Canadian dollar can also respond to interest-rate differentials, the U.S. dollar, trade conditions, capital flows, and market sentiment. For Canadian portfolios, commodity exposure can occur through direct holdings, Canadian equities, company revenues, and currency movements.

Correlation can describe how commodity prices and the Canadian dollar have moved together over a selected period, but it does not establish causation. Historical relationships provide context, but they do not indicate future performance.
