Commodity Investing:
3 Asset Classes That Beat Inflation

When inflation surged past 9% in 2022 and your portfolio lost purchasing power, one asset class stood resilient: commodities. Gold climbed to record highs above $4,900 per ounce in 2025, oil prices swung wildly with geopolitical tensions, and agricultural commodities reminded investors why tangible assets matter in an increasingly digital world.

Yet most individual investors have zero commodity exposure. They understand stocks and bonds, maybe real estate, but commodities remain a mystery—something traders in Chicago pits deal with, not regular investors building retirement portfolios. This guide changes that. Whether you want to diversify your portfolio, hedge against inflation, or simply understand how the global economy's essential building blocks can fit into your investment strategy, you'll find actionable guidance here.

What Is Commodity Investing?

Commodities are raw materials and primary agricultural products that can be bought and sold. Unlike stocks (ownership in companies) or bonds (loans to governments or corporations), commodities are tangible goods—you can touch, store, and use them.

Commodity investing means gaining exposure to the price movements of these raw materials, either directly (owning physical gold) or indirectly (through ETFs, stocks of commodity producers, or futures contracts).

The Four Ways to Invest in Commodities

The Three Commodity Categories

While dozens of individual commodities trade on global exchanges, they fall into three broad categories that matter most for portfolio construction.

1. Precious Metals: Gold, Silver, and Platinum

Precious metals have served as stores of value for thousands of years. Gold, in particular, is often called the ultimate "crisis commodity"—when stocks crash, geopolitical tensions rise, or currencies lose purchasing power, investors flock to gold.

2. Energy: Oil, Natural Gas, and Gasoline

Energy commodities power the global economy. Oil prices affect everything from transportation costs to plastics manufacturing to heating bills. For investors, energy commodities offer both diversification and exposure to global economic growth.

3. Agricultural Products: Corn, Wheat, Soybeans

Agricultural commodities represent the food and fiber that sustain human civilization. Unlike metals or energy, agricultural commodities face unique supply factors: weather patterns, crop diseases, and seasonal planting cycles can create dramatic price swings.

Gold Investing: The Ultimate Inflation Hedge

Gold deserves special attention because it's the commodity most accessible to individual investors and has the longest track record as a store of value.

Why Gold Works as a Portfolio Diversifier

• Low Correlation: Gold historically has near-zero correlation with stocks over long periods
• Crisis Performance: Gold often rises when stocks fall during financial crises
• Currency Hedge: Gold tends to rise when the U.S. dollar weakens
• Inflation Protection: Gold has maintained purchasing power over centuries

How to Invest in Gold

Oil and Energy Investing

Oil is the world's most important commodity by trading volume. Understanding oil markets provides insight into global economic health, geopolitical dynamics, and inflation pressures.

Understanding Oil Price Dynamics

Oil prices respond to a complex mix of factors:

• OPEC+ Decisions: Production cuts or increases directly impact supply
• Global Demand: Economic growth drives oil consumption
• Geopolitical Events: Conflicts in oil-producing regions create supply fears
• U.S. Shale Production: American producers can ramp up when prices rise
• Energy Transition: EV adoption creates long-term demand uncertainty

Ways to Invest in Oil

The Contango Problem

Commodity futures ETFs face a unique challenge: they must periodically "roll" their futures contracts forward as they approach expiration. When futures markets are in "contango" (future prices higher than current spot prices), this rolling process creates performance drag.

Agricultural Commodities

Agricultural commodities—corn, wheat, soybeans, coffee, sugar—offer unique exposure to global food markets. Unlike metals or energy, agricultural prices respond heavily to weather patterns, making them among the most volatile commodity categories.

Key Agricultural Commodities

• Corn: Used for food, animal feed, and ethanol; U.S. is largest producer
• Wheat: Essential food staple; global supply sensitive to weather in Russia, Ukraine, U.S.
• Soybeans: Critical for cooking oil and animal feed; China is largest importer
• Coffee: Global beverage staple; Brazil dominates production

Agricultural ETF Options

Commodity ETFs and Funds

For most investors, diversified commodity ETFs offer the simplest entry point. These funds hold baskets of commodity futures, providing broad exposure without the complexity of trading individual contracts.

Top Broad Commodity ETFs

Commodity Stocks: Leveraged Exposure

Instead of buying commodities directly, you can invest in companies that produce them. This approach offers potential advantages—and distinct risks.

How Commodity Stocks Provide Leverage

A gold mining company has relatively fixed costs (labor, equipment, energy). When gold prices rise 10%, the company's profit margin might expand 20-30% because costs stay constant. This creates leveraged exposure to commodity prices.

Risks of Commodity Stocks

• Operational Risks: Mine accidents, labor strikes, equipment failures
• Management Decisions: Poor capital allocation, excessive debt
• Political Risk: Nationalization, changing regulations in host countries
• Reserve Depletion: Mines have finite lives

How Much Should You Allocate?

The right commodity allocation depends on your goals, risk tolerance, and existing portfolio composition. Most financial advisors suggest a modest allocation rather than a large bet.

General Guidelines

Tax Implications of Commodity Investing

Commodity investments receive different tax treatment depending on the investment vehicle. Understanding these nuances can significantly impact after-tax returns.

Risks of Commodity Investing

Commodities offer diversification benefits, but they also carry unique risks that differ from traditional stock and bond investments.

Key Risks to Understand

• High Volatility: Commodity prices can swing 20-50% or more in a single year
• No Income: Unlike stocks (dividends) or bonds (interest), commodities generate no cash flow
• Contango Drag: Futures-based ETFs may significantly underperform spot prices over time
• Currency Risk: Most commodities are priced in U.S. dollars; currency movements affect returns
• Geopolitical Risk: Supply disruptions from wars, sanctions, or political instability
• Weather Risk: Agricultural commodities are highly sensitive to droughts, floods, and extreme weather

Getting Started: A Beginner's Roadmap

Ready to add commodities to your portfolio? Follow this step-by-step approach, starting with the asset allocation fundamentals.

Step 1: Determine Your Allocation

Start with 5% of your portfolio for commodities. You can adjust based on your inflation concerns and conviction level.

Step 2: Choose Your Vehicle

For most beginners, a single diversified commodity ETF like DBC or PDBC provides sufficient exposure. As you learn more, you might add specific positions in gold or energy.

Step 3: Open a Brokerage Account

If you don't already have one, open an account with a major broker like Fidelity, Schwab, or Vanguard. Commodity ETFs trade like regular stocks.

Step 4: Start Small and Learn

Make your initial commodity investment modest. Observe how commodity prices move relative to your other holdings. Expand your position only as your understanding grows.

Frequently Asked Questions

Are commodities a good hedge against inflation?

Historically, yes. Commodities are real assets whose prices tend to rise with the general price level. Gold, in particular, has maintained purchasing power over centuries. However, short-term performance varies, and commodities can underperform during periods of falling or stable inflation.

Should I invest in physical gold or gold ETFs?

For most investors, gold ETFs offer superior convenience and lower costs. Physical gold makes sense if you want assets completely outside the financial system, are concerned about systemic risks, or have very large positions that justify storage costs.

Why do commodity ETFs often underperform the actual commodities?

Most commodity ETFs use futures contracts rather than holding physical commodities. The costs of rolling these futures forward (especially during contango) create performance drag. Some ETFs like PDBC use active management to minimize this issue.

Can I invest in commodities through my 401(k)?

Many 401(k) plans offer commodity funds or target-date funds with commodity exposure. Check your plan's investment options. If direct commodity exposure isn't available, you might find natural resources or materials sector funds.

Are commodity futures suitable for beginners?

Generally, no. Futures contracts are complex, require margin accounts, and can result in losses exceeding your initial investment. Beginners should stick to ETFs or stocks until they thoroughly understand futures mechanics.

The Bottom Line

Commodity investing offers something unique in a portfolio dominated by stocks and bonds: exposure to the physical building blocks of the global economy. When inflation erodes purchasing power, when geopolitical tensions disrupt supply chains, when central banks print money—commodities often move differently than paper assets.

But commodities aren't a free lunch. They generate no income, can experience dramatic volatility, and require understanding of unique factors like contango and roll costs. The key is using commodities strategically—as diversifiers and inflation hedges—rather than speculative bets on price movements.

Whether you choose a simple gold ETF, a diversified commodity fund, or a basket of commodity producer stocks, the goal remains the same: building a resilient portfolio that can weather inflation, market corrections, and economic uncertainty. In an unpredictable world, having exposure to tangible assets that humanity has valued for millennia provides a different kind of security than any stock certificate ever could.
