Commodities are raw materials and primary goods, like wheat, crude oil, gold, and livestock, that are interchangeable enough to trade in standardized quantities on organized exchanges. Under U.S. federal law, the category is even wider: it covers a specific list of agricultural products and then sweeps in any good, article, service, right, or interest in which futures contracts are traded or may be traded.1Office of the Law Revision Counsel. 7 USC 1a – Definitions What makes something a commodity in practice is fungibility. One barrel of a given grade of oil is worth the same as any other barrel of that grade, no matter who pulled it out of the ground. That uniformity is what lets a farmer in Kansas and a food manufacturer in Japan agree on a price months in advance without ever meeting.
How the Law Defines a Commodity
The Commodity Exchange Act names specific agricultural products, including wheat, cotton, corn, rice, soybeans, livestock, and butter, and then adds a catch-all covering all other goods and services with existing or potential futures contracts.1Office of the Law Revision Counsel. 7 USC 1a – Definitions That broad language pulls in gold, natural gas, coffee, and even certain financial instruments.
For a market to function, every unit traded has to be interchangeable with every other unit of the same grade. The Commodity Futures Trading Commission enforces that standardization by requiring exchanges to set specific grades, delivery points, and quality benchmarks for every product traded.2Commodity Futures Trading Commission. 17 CFR Part 5 – Economic and Public Interest Requirements for Contract Market Designation Manipulating these markets or spreading false information about crop conditions or market data is prohibited by statute,3Office of the Law Revision Counsel. 7 USC 9 – Prohibition Regarding Manipulation and False Information and civil penalties can reach $1,487,712 per violation in a CFTC administrative action.4Commodity Futures Trading Commission.

Hard Commodities and Soft Commodities
Commodities split into two broad families based on how they’re produced.
Hard commodities are extracted from the earth through mining or drilling. This group includes precious metals like gold and silver, industrial metals like copper, aluminum, and zinc, and energy products like crude oil and natural gas. Deposits exist in finite quantities and are concentrated in specific regions, so prices are sensitive to geopolitical disruption. Extraction requires heavy capital investment and long permitting timelines before anything salable comes out of the ground.
Gold trades on the COMEX division of CME Group in contracts of 100 troy ounces each.5CME Group. Gold Futures Contract Specs A single full-size contract represents a substantial dollar exposure, which is why most retail investors access gold through smaller instruments like micro futures or exchange-traded funds. Physical gold held in professional vaults typically carries annual storage and insurance fees of roughly 0.50% to 1.00% of the metal’s value, with segregated storage costing more than pooled arrangements.
Soft commodities are grown or raised: staple grains like corn and wheat, tropical crops like coffee, cocoa, and sugar, and livestock including cattle and hogs. Renewal depends on weather, soil, and growing seasons that no one controls. A drought in the U.S. Midwest can slash corn yields in weeks. These goods also have limited shelf life, so they have to move through the supply chain before spoilage matters.

How Commodity Markets Work
Commodity trading happens on organized exchanges that bring buyers and sellers together under a single rulebook. The major U.S. venues, including the Chicago Board of Trade and the New York Mercantile Exchange (both now part of CME Group), operate under CFTC oversight.10U.S. Government Accountability Office. Commodity Futures Trading Commission and the Chicago Futures Exchanges Detection of Trade Practice Abuses The CFTC can direct an exchange to fix its enforcement practices or revoke its operating authority for failing to police trading abuses.
A central clearinghouse sits between every buyer and seller, guaranteeing both sides of each trade. If the buyer defaults, the clearinghouse still pays the seller, and vice versa. To make that guarantee credible, exchanges require margin deposits from both parties and enforce daily settlement, marking every open position to the current market price and demanding additional funds when losses mount.
Spot Markets Versus Futures
In a spot market, physical goods change hands for immediate payment and delivery. A grain elevator buying corn from a farmer at today’s price is a spot transaction. Futures contracts, by contrast, lock in a price for delivery on a specified future date. A wheat farmer might sell July futures in March to guarantee a price for the coming harvest, while a bread manufacturer buys the same contract to lock in input costs. Most futures contracts are closed out before delivery by taking an offsetting position, but the option to make or take physical delivery is what ties futures prices to real-world supply and demand.
Contango and Backwardation
Futures prices don’t always match the spot price, and the relationship between the two says a lot about market conditions. When futures trade at a premium to the spot price, the market is in contango. When futures trade at a discount, it’s in backwardation.11CME Group. What is Contango and Backwardation Contango is the more common state for physical commodities because storage fees, insurance, and financing costs all get priced into a longer-dated contract. Backwardation signals tight supplies: buyers want the commodity now badly enough to pay more for immediate delivery than for future delivery.
As a futures contract approaches expiration, its price converges with the spot price. If it didn’t, traders could lock in a risk-free profit by buying in one market and selling in the other, and that arbitrage pressure keeps the two tethered.
Ways to Invest in Commodities
Investors reach commodity markets through several different structures, each with its own trade-offs.
- Futures contracts. The most direct route. You agree to buy or sell a specific quantity at a set price on a future date. Futures offer leverage because you post only a margin deposit rather than the full contract value, and that leverage amplifies losses as easily as gains. There are no ongoing management fees, and futures trade nearly 24 hours a day, six days a week.
- Exchange-traded funds. Commodity ETFs pool investor money into a fund that may hold futures contracts, physical commodities, or shares of commodity-producing companies. They trade like stocks in a regular brokerage account. The trade-offs are an annual management fee and less precise tracking of the underlying commodity, partly because the fund must periodically roll expiring futures into new contracts.
- Physical ownership. Buying gold bars, silver coins, or other tangible commodities gives you direct exposure with no counterparty risk, but you absorb storage and insurance costs. This works best for precious metals; nobody stores barrels of crude oil in a garage.
- Managed futures accounts. A Commodity Trading Advisor registered with the CFTC and the National Futures Association runs a portfolio of futures positions on your behalf. Fees typically include a management fee plus a performance fee on gains. Hands-off, but expensive.
Tax Rules for Commodity Futures
Commodity futures get unusual tax treatment. Under 26 U.S.C. ยง 1256, regulated futures contracts are marked to market at year-end, meaning any unrealized gains or losses are treated as if you closed the position on the last business day of the year.12Office of the Law Revision Counsel. 26 USC 1256 – Section 1256 Contracts Marked to Market You owe tax on those paper gains even if you haven’t sold anything.
The offsetting benefit is a favorable rate split. Sixty percent of any gain is taxed as long-term capital gain and forty percent as short-term, regardless of how long you held the contract.13Internal Revenue Service. Gains and Losses From Section 1256 Contracts and Straddles (Form 6781) For a trader in the top bracket, that blended rate comes in well below the ordinary income rate that would apply to short-term stock gains. The 60/40 split applies to regulated futures contracts, foreign currency contracts, and nonequity options, but not to interest rate swaps, currency swaps, or commodity swaps.12Office of the Law Revision Counsel. 26 USC 1256 – Section 1256 Contracts Marked to Market Gains and losses are reported on IRS Form 6781.
Risks You Should Know Before Trading
Commodity futures are among the riskiest instruments available to retail investors, and federal law requires brokers to say so upfront. Before opening a commodity account, your futures commission merchant must give you a written risk disclosure statement that you sign and date.14eCFR. 17 CFR 1.55 – Public Disclosures by Futures Commission Merchants The warnings are blunt: you can lose your entire deposit, you may face margin calls demanding substantial additional funds on short notice, and if you can’t meet those calls your positions may be liquidated at a loss with you still owing the deficit.
Customer funds deposited with a futures broker are not insured. They are not covered by the Securities Investor Protection Corporation, not guaranteed by a clearinghouse in a broker insolvency, and not held in a separate account for your individual benefit.14eCFR. 17 CFR 1.55 – Public Disclosures by Futures Commission Merchants Brokers commingle customer funds in pooled accounts, so another customer’s catastrophic losses could theoretically affect your balance if the broker is undercapitalized. Under certain market conditions, including limit moves where trading halts at a daily price ceiling or floor, exiting a losing position may be impossible.
Leverage and Margin
Leverage is the source of both the opportunity and the danger. Margin deposits typically represent a fraction of a contract’s full value, so a small price move produces outsized percentage gains or losses on your deposit. A 5% drop in the price of the underlying commodity can wipe out a margin deposit that represented 10% of the contract’s value, and leave you owing more. Exchanges set minimum margin requirements that vary by product and adjust with market volatility.
Speculative Position Limits
To prevent any single trader from cornering a market, the CFTC imposes federal speculative position limits on 25 core commodity futures contracts covering agricultural products, energy, and metals.15eCFR. 17 CFR Part 150 – Limits on Positions These caps limit the number of contracts one person can hold in the spot month, in any single delivery month, and across all months combined. Hedgers with a legitimate commercial need for the commodity can apply for exemptions; purely speculative traders are bound by the caps.
Verifying a Broker Before You Fund an Account
Before sending money to a commodity broker or trading advisor, check whether the firm is properly registered through the National Futures Association’s BASIC system (Background Affiliation Status Information Center). It’s a free online tool that shows current registration status, NFA membership, and any regulatory or disciplinary actions. Commodity professionals who trade customer funds must be registered with both the CFTC and the NFA, and skipping this verification is one of the easiest ways to end up with an unregistered operator running your money.
