Commodity Price Risk: Definition, Calculation, and Main Risks

What Is Commodity Price Risk?

Commodity price risk is the possibility that commodity price changes will cause financial losses for either commodity buyers or producers. Buyers face the risk that commodity prices will be higher than expected. Many furniture manufacturers must buy wood, for example, so higher wood prices increase the cost of making furniture and negatively impact furniture makers' profit margins.

Lower commodity prices are a risk for commodity producers. If crop prices are high this year, a farmer may plant more of that crop on less productive land. If prices fall next year, the farmer may lose money on the additional harvest planted on less fertile soil. This, too, is a type of commodity price risk. Both producers and consumers of commodities can hedge this risk using commodities markets.

Key Takeaways

  • Commodity price risk is the chance that commodity prices will change in a way that causes economic losses.
  • Commodity price risk for buyers is due to increases in commodity prices; for sellers/producers it is often due to decreases in commodity prices.
  • Futures and options are two instruments commonly used to hedge against commodity price risk.
  • Factors that can influence commodity prices include politics, seasons, weather, technology, and market conditions.

Understanding Commodity Price Risk

Commodity price risk is a real risk to businesses and consumers, and not just to traders in commodities markets. This is because everything from raw materials to finished products depend on buying and processing various commodities, from metals and energy to agricultural and food products. As a result, changes in prices can impact things from the price of gas at the pump to that of groceries or plastic goods.

The Risk to Buyers: Automobile Manufacturers

Commodity price risk to buyers stems from unexpected increases in commodity prices, which can reduce a buyer's profit margin and make budgeting difficult. For example, automobile manufacturers face commodity price risk because they use commodities like steel and rubber to produce cars.

A case in point: In the first half of 2016, steel prices jumped 36%, while natural rubber prices rebounded by 25% after declining for more than three years. This led many Wall Street financial analysts to conclude that auto manufacturers and auto parts makers could see a negative impact on their profit margins.

The Risk to Producers: Oil Companies

Producers of commodities face the risk that commodity prices will fall unexpectedly, which can lead to lower profits or even losses for producers. Oil-producing companies are exceptionally aware of commodity price risk. As oil prices fluctuate, the potential profit these companies can make also fluctuates. Some companies publish sensitivity tables to help financial analysts quantify the exact level of commodity price risk a company faces.

The French oil company Total SA, for example, once stated that its net operating income would fall by $2 billion if the price of a barrel of oil decreased by $10. Similarly, their operating cash flow would drop by $2 billion when the oil price dropped by $10. From June 2014 to January 2016, oil prices fell by over $70 per barrel. This price move should have reduced Total's operating cash flow by about $17 billion during that period.

Hedging Commodity Price Risk

Major companies often hedge commodity price risk. One way to implement these hedges is with commodity futures and options contracts traded on major commodities exchanges like the Chicago Mercantile Exchange (CME) or the New York Mercantile Exchange (NYMEX). These contracts can benefit commodity buyers and producers by reducing price uncertainty.

Producers and buyers can protect themselves from fluctuations in commodity prices by purchasing a contract that guarantees a specific price for a commodity. They can also lock in a worst-case scenario price to reduce potential losses.

Futures and options are two financial instruments commonly used to hedge against commodity price risk.

Factors in Commodity Price Fluctuations

Factors that can influence commodity prices include politics, seasons, weather, technology, and market conditions. Some of the most economically essential commodities include raw materials, such as the following:

  • Cotton
  • Corn
  • Wheat
  • Oil
  • Sugar
  • Soybeans
  • Copper
  • Aluminum
  • Steel

Political Factors

Political factors can raise the price of some commodities while reducing the price of others. In 2018, former President Donald Trump imposed tariffs on steel and aluminum imported from foreign countries. The direct effect of these tariffs was to increase steel and aluminum prices in the United States relative to the rest of the world.

China retaliated against Trump's tariffs by imposing its own tariffs on U.S. agricultural products. With lower demand from China, excess crops must be sold in other markets. As a result, many crop prices were down in the United States in 2019.


Seasonal and other weather fluctuations have a substantial impact on commodity prices. The end of summer brings with it plentiful harvests, so commodity prices tend to fall in October. These seasonally depressed commodity prices may be one reason major stock market crashes often happen in October. Droughts and floods can also lead to temporary increases in the prices of certain commodities.


Technology can have a dramatic influence on commodity prices. Aluminum was considered a precious metal until procedures for isolating it improved during the 19th and 20th centuries. As technology advanced, aluminum prices collapsed.
