When investors talk about "Hard Assets," they are most often referring to commodities. A commodity is a basic raw material used in commerce that is interchangeable with other goods of the same type . The key feature of a commodity is its lack of differentiation. A barrel of "Brent Crude" oil is the same whether it was produced in Norway or Nigeria. A bushel of corn is a bushel of corn, regardless of which farm it came from . This interchangeability makes them easy to trade on global exchanges.

Hard vs. Soft Commodities: Knowing the Difference

Commodities are generally split into two categories based on how they are acquired:

Hard Commodities: These are natural resources that must be mined or extracted from the earth. Examples include gold, silver, copper, oil, and natural gas .
Soft Commodities: These are agricultural products or livestock that are grown or ranched. Examples include wheat, corn, coffee, sugar, and beef .

Energy	Oil, Natural Gas	Transportation, Heating, Electricity
Metals	Copper, Lithium	Construction, Electronics, EV Batteries
Agriculture	Wheat, Soybeans	Food Production, Biofuels
Livestock	Cattle, Hogs	Food Supply

Why Commodities Rise with Inflation

Commodities have a unique relationship with inflation: they are often the cause of it. Because commodities are the "inputs" for almost everything we buy, when their prices go up, the price of the final product must also go up . For example, if the price of grain rises, the price of bread, cereal, and even beef (since cattle eat grain) will eventually rise.

Because of this, commodities are often seen as a "leading indicator" of inflation. Investors flock to them when they see prices starting to creep up, which further drives up the demand and the price of the commodities themselves . This makes them an excellent hedge; as the value of your dollar goes down, the value of the "stuff" your dollar buys (the commodities) tends to go up.

The Role of the Futures Market

Most commodity trading doesn't involve people actually shipping barrels of oil to each other's houses. Instead, it happens through Futures Contracts. A futures contract is an agreement to buy or sell a specific amount of a commodity at a set price on a specific date in the future .

There are two main types of people in this market:

Hedgers: These are the producers and users of the commodities. For example, a wheat farmer might sell a futures contract to lock in a price for his crop before it's even harvested. This protects him if the price of wheat drops later .
Speculators: These are investors who have no intention of ever touching a bushel of wheat. They buy and sell contracts hoping to profit from the price movements. They provide the "liquidity" that allows the market to function .

Investing in Commodities: Practical Avenues

For a beginner, buying physical commodities (like a tank of oil) is impractical. Instead, most investors use indirect methods:

Commodity ETFs: Exchange-Traded Funds allow you to buy shares in a fund that tracks the price of a specific commodity or a basket of them. For example, the iShares S&P GSCI Commodity-Indexed Trust (GSG) provides broad exposure to many different raw materials .
Mutual Funds: Some funds specialize in the stocks of companies that produce commodities, such as mining or oil companies.
Direct Ownership: This is usually reserved for precious metals (like gold coins) or real estate, which we will cover in the next sections.

Risks and Volatility in Commodity Trading

While commodities are great for inflation protection, they are notoriously volatile. Their prices are driven by supply and demand, which can be affected by things completely outside of an investor's control:

Geopolitical Tensions: A war in a country that produces oil can cause prices to skyrocket overnight .
Natural Disasters: A drought in the Midwest can destroy the corn crop, leading to a massive spike in prices .
Economic Shocks: A global recession can cause demand for industrial metals like copper to collapse, as construction projects are put on hold .

Experts often suggest that average investors dedicate no more than 10% of their portfolio to commodities to balance these risks .
