Commodities are the raw materials that power the economy, from oil and natural gas to wheat, copper, and coffee. Some investors add them to a portfolio for diversification or as a hedge against inflation, but they behave very differently from stocks. This guide from The Finance Reveal explains how to invest in commodities, part of our Investing section. This is general education, not investment advice, and commodities are volatile and involve risk, including possible loss of principal.

What Commodities Are

Commodities are basic goods that are largely interchangeable regardless of who produces them, which is why they trade on standardized markets. They fall into broad groups: energy, such as crude oil and natural gas; metals, including industrial metals like copper and precious metals like gold and silver; and agricultural products, such as grains, coffee, and livestock. Because a barrel of a given grade of oil is essentially the same from any producer, price rather than brand drives the market.

The key thing to understand is that commodities do not generate income. Unlike a stock that may pay dividends or a bond that pays interest, a barrel of oil or a bushel of wheat produces nothing while you hold it. Your return depends entirely on the price rising, and prices are driven by supply and demand factors like weather, geopolitics, production decisions, and economic growth. That makes them notably volatile, which is why they suit a modest supporting role rather than the core of a portfolio, as our guide to asset allocation explains.

Ways to Invest

There are several routes into commodities, each with different complexity and risk. The table below summarizes them.

For most everyday investors, the simplest approach is a fund or exchange-traded fund that provides exposure to a commodity or a basket of them, since it can be bought through an ordinary brokerage account without dealing in physical goods. Another indirect route is buying shares of companies that produce commodities, such as energy or mining firms, though these are stocks whose prices reflect company performance as well as commodity prices. Owning the physical commodity is generally practical only for precious metals, which our guide to how to invest in gold covers, since storing oil or grain is not realistic for individuals. Finally, futures contracts are the direct market for commodities, but they involve leverage, expiration dates, and substantial risk, making them unsuitable for beginners and closer in spirit to the speculation our guide to day trading warns about.

Approaching Commodities Sensibly

Commodities can serve a purpose in a portfolio. They sometimes move differently from stocks and bonds, offering diversification, and they have historically been viewed as a potential hedge against inflation, since rising raw-material prices often accompany rising prices generally. But those benefits come with real volatility, since commodity prices can swing sharply on weather, conflict, or shifting demand, and with no income to cushion the ride.

For these reasons, commodities generally belong as a small, supporting slice of a diversified portfolio rather than a core holding, if you include them at all. Many investors get incidental commodity exposure already through broad stock funds that hold energy and mining companies. Costs matter too, since some commodity funds carry higher fees or structural quirks worth understanding before you buy. The essential message is that commodities are raw materials like oil, metals, and crops that produce no income and depend on price movements driven by supply and demand, and that most investors access them most simply through funds or ETFs, or indirectly through producer shares, while futures are complex and high-risk. Used in moderation for diversification, they can complement a portfolio, but they are volatile and should not replace the steady core of long-term investing.

Frequently Asked Questions

How do you invest in commodities?

The simplest route for most people is a commodity fund or exchange-traded fund bought through an ordinary brokerage account, which gives exposure to one commodity or a basket without handling physical goods. You can also invest indirectly by buying shares of producers like energy or mining companies. Physical ownership is generally practical only for precious metals. Futures contracts trade commodities directly but involve leverage and expiration dates, making them high-risk and unsuitable for beginners.

Are commodities a good investment?

They can play a useful supporting role. Commodities sometimes move differently from stocks and bonds, offering diversification, and have historically been viewed as a potential inflation hedge. However, they are volatile, with prices swinging on weather, geopolitics, and demand shifts, and they produce no income like dividends or interest, so returns depend entirely on price rising. Most investors are best served keeping commodities as a small slice of a diversified portfolio rather than a core holding.

What are examples of commodities?

Commodities fall into three broad groups. Energy commodities include crude oil and natural gas. Metals include industrial metals like copper and precious metals like gold and silver. Agricultural commodities include grains such as wheat and corn, plus products like coffee, sugar, and livestock. What unites them is that they are basic goods that are largely interchangeable regardless of producer, which is why they trade on standardized markets where price, not brand, drives the market.

Should beginners invest in commodity futures?

Generally, no. Futures contracts are the direct market for commodities, but they involve leverage that magnifies both gains and losses, expiration dates, and substantial risk, making them complex and unsuitable for beginners. Investors wanting commodity exposure are far better served by simple commodity funds or ETFs, or by shares of producing companies, both of which can be bought through an ordinary brokerage account without the outsized risks that come with futures trading.

The Bottom Line

Commodities are the raw materials underpinning the economy, spanning energy like crude oil and natural gas, metals including copper, gold, and silver, and agricultural goods such as grains, coffee, and livestock, all largely interchangeable regardless of producer, which is why they trade on standardized markets. The defining characteristic for investors is that commodities produce no income: unlike a dividend-paying stock or an interest-paying bond, a barrel of oil generates nothing while you hold it, so your return depends entirely on the price rising, driven by supply and demand factors like weather, geopolitics, production decisions, and economic growth. That makes them notably volatile. For access, the simplest route for most investors is a commodity fund or ETF bought through a regular brokerage account, followed by indirect exposure through shares of energy or mining companies, while physical ownership is realistic mainly for precious metals and futures contracts remain complex, leveraged, and high-risk, unsuitable for beginners. Commodities can serve a purpose, offering diversification since they sometimes move differently from stocks and bonds, and they have historically been seen as a potential inflation hedge, but those benefits come with sharp price swings and no income to cushion them. For that reason they belong as a small, supporting slice of a diversified portfolio rather than a core holding, and many investors already have incidental exposure through broad stock funds. Mind fund costs and structural quirks before buying.
