In today’s unpredictable economic climate, investors increasingly seek ways to safeguard their portfolios against inflation and market volatility.

Commodity ETFs have emerged as a dynamic solution, offering diversified exposure across various asset classes—from time-tested precious metals to innovative alternatives like cryptocurrency, food, and water resources.

This post will guide you through the world of commodity ETFs, explain the underlying concept of spot prices and how ETFs track them, and illustrate why these funds are a smart tool for portfolio diversification. Buckle in, this is an extensive one.

Commodities as an Inflation Hedge

Inflation—the gradual rise in prices and the erosion of purchasing power—has long been a nemesis for investors. When inflation occurs, the purchasing power of money declines, but tangible assets tend to hold their worth.

By their very nature, commodities are physical goods in limited supply and have intrinsic value, which is the perceived value of an asset. People buy gold because gold has had value throughout human history.

As inflation drives up the cost of goods and services, the prices of commodities typically follow suit. This is because the same economic factors that cause consumer prices to rise—such as increased demand, supply shortages, or rising production costs—also push up commodity prices.

Increases in commodity prices can also lead to inflation. For example, when there have been oil price shocks, the overall cost of goods and services increased. At the simplest level, that is because of oil’s importance in transporting basic goods and services.

By owning commodities via ETFs, investors gain exposure to the price movements of these essential goods without needing to purchase and store the physical products. This makes commodity ETFs an attractive option for preserving wealth during inflationary periods.

Nothing better illustrates the relationship between commodity prices and inflation than two popularly tracked economic gauges.

• Producer Price Index (PPI): measures the price change paid to U.S. producers of goods and services. Commodity prices are the inputs to producers and heavily influence PPI.
• Consumer Price Index (CPI) measures the change in the price at which U.S. consumers pay for goods and services.   

Below are interactive graphs of PPI and CPI provided by the St. Louis Federal Reserve. You will be able to quickly see the relationship between the two indices. Steep increases in PPI often results in elevated inflation.

Understanding Commodity ETFs

What Is the Spot Price?

At the heart of commodity investing is the spot price—the current market price at which a commodity can be bought or sold for immediate delivery. For example, the spot price of gold is the current price per ounce at which gold is traded on the market. This price serves as the benchmark for many commodity ETFs.

How Do Commodity ETFs Track Spot Prices?

• Physically-Backed ETFs: These funds hold the actual physical commodity (like gold bullion or silver bars). Their value closely mirrors the spot price because the fund’s assets are directly linked to the commodity.
• Futures-Based ETFs: Instead of holding the physical commodity, these ETFs invest in futures contracts and agreements to buy or sell a commodity at a predetermined price on a specific date. While this method exposes the commodity’s price movements, it can lead to tracking errors due to contract rollovers and other factors.

Key Benefits

• Transparency: Investors can see how the spot price influences the ETF’s performance.
• Simplicity: ETFs eliminate the need for investors to directly purchase and store commodities while still capturing the price dynamics of the underlying asset.
• Diversification: Whether through physical holdings or futures, commodity ETFs allow investors to diversify their portfolios across different asset classes with relative ease.

Broad-Basket Commodity ETFs

Before delving into more specialized categories, it’s worth considering broad-basket commodity ETFs. These funds provide exposure to a diversified mix of commodities, reducing the risk associated with any single commodity’s volatility.

Broad-basket commodity ETFs typically track indices, including various assets—energy, metals, agriculture, etc. This diversification helps smooth out the impact of price fluctuations in any sector, making these ETFs a compelling option for investors seeking a balanced approach.

Themed Commodity ETFs

Commodity ETFs come in many flavors. Below, we explore several key categories that can enrich your portfolio.

One thing to note – Commodity ETFs do not yield dividends and they often have higher than average expense ratios to pay for the cost of housing physical commodity assets and tracking their prices.

Metals ETFs

Precious metals have always been the bedrock of wealth preservation. Gold and silver ETFs, such as SPDR Gold Shares and iShares Silver Trust, are classic choices for investors seeking stability during turbulent times. But metals ETFs extend beyond these familiar names.

• Gold & Silver: Traditional safe havens and proven inflation hedges.
• Other Metals: ETFs tracking platinum, palladium, and industrial metals like copper, platinum, and palladium provide exposure to sectors essential for manufacturing and industrial growth.

Energy ETFs

Energy remains one of the world’s most critical and dynamic sectors. Energy ETFs come in several forms:

• Oil & Natural Gas: ETFs like the United States Oil Fund provide exposure to traditional fossil fuels, whose prices are influenced by geopolitical events and global supply-demand dynamics.

• Renewable Energy: With a growing focus on sustainability, renewable energy ETFs capture the momentum behind solar, wind, and other clean energy sources, aligning investment strategies with environmental, social, and governance (ESG) criteria. These ETFs invest in the companies who produce clean energy, which makes sense since you can’t stockpile air and sunlight.

Note: Physical Uranium ETFs are just beginning to emerge, which is why UX has a small AUM. UX started trading on Jan 29, 2025. Sprott Uranium (URNM) holds 10% of its assets in physical Uranium.

Agriculture & Crop ETFs

Agriculture ETFs offer a unique window into a sector that feeds the world. Yet, to capture the full spectrum of food-related investments, looking at ETFs that track crops, livestock, and specific food commodities is valuable.

Unique and Alternative Commodity ETFs

Beyond the traditional sectors, innovative commodity ETFs expose less conventional yet increasingly important assets.

• Water ETFs: With water scarcity emerging as a critical issue, ETFs like Invesco Water Resources and iShares Global Water ETF offer exposure to companies focused on water purification and distribution.
• Timber ETFs: Sustainable forestry ETFs, such as the iShares Global Timber & Forestry ETF, enable investors to tap into a unique asset class.
• Lithium & Battery Metals ETFs: As electric vehicles and renewable energy storage grow in importance, ETFs tracking lithium and battery metals are gaining traction.
• Carbon Credit ETFs: These emerging ETFs track carbon credits, offering exposure to environmental commodities and supporting the global shift toward reducing greenhouse gas emissions.
• Rare Earth & Industrial Minerals: These ETFs focus on niche sectors and cater to the high-tech and defense industries.
• Base Metals ETFs: ETFs like the Invesco DB Base Metals Fund provide exposure to industrial metals such as aluminum and zinc for added diversification.

Cryptocurrency ETFs

As digital assets continue to shake up traditional financial markets, cryptocurrency ETFs are becoming a compelling, albeit volatile, addition to any diversified portfolio. Bitcoin and Ethereum ETFs offer exposure to digital currencies without the need to manage digital wallets or navigate complex exchanges.

While still in their infancy compared to metals, these ETFs are paving the way for more diverse digital asset offerings in the future. Presently, there are only ETFs tracking the spot prices of Bitcoin and Ethereum.

Considerations When Investing in Commodity ETFs

While commodity ETFs offer diverse benefits, they also come with unique risks:

• Market Volatility: Prices can be highly volatile due to geopolitical events, natural disasters, and economic cycles.
• Expense Ratios and Tracking Errors: Variations in fees and tracking methods can impact returns.
• Liquidity and Trading Volume: Ensure the chosen ETFs have sufficient liquidity for easy trading.
• Global Economic and Geopolitical Influences: International events and policy changes can affect commodity prices, influencing ETF performance.
