Commodities Explained
Commodities are the raw physical inputs the world runs on — oil, gold, wheat, copper — traded in markets where price is set by the tug-of-war between actual supply and actual demand.
What makes commodities different
A commodity is a raw material that is broadly interchangeable regardless of who produced it — a barrel of crude oil, an ounce of gold, or a bushel of wheat is treated as functionally the same product no matter the source, which is what allows it to trade on a standardized exchange. That interchangeability is the key difference from stocks: an investor is not buying a claim on a company's management or growth strategy, but a direct bet on the physical supply and demand of a real-world good.
Commodities are typically grouped into three broad buckets: energy (crude oil, natural gas), metals (gold, silver, copper, and other industrials), and agriculture (wheat, corn, soybeans, coffee). Each group responds to a different mix of drivers, but all of them ultimately trade on the same basic tension — how much exists and is available now, versus how much the world wants to buy.
What actually moves prices
Supply shocks are the most visible driver: a hurricane knocking out Gulf Coast refineries, a drought cutting a grain harvest, or a mine strike curbing copper output can move prices sharply within days. Demand shifts tend to move more slowly but matter just as much — global industrial activity drives demand for oil and copper, while a strengthening economy in a populous country can shift agricultural demand for years.
Two forces sit apart from ordinary supply and demand. The first is the U.S. dollar: because most commodities are priced in dollars globally, a weaker dollar makes commodities cheaper for buyers using other currencies, often pushing prices up, and a stronger dollar tends to do the reverse. The second is geopolitics — oil in particular is exposed to conflict or sanctions in producing regions, since a disruption to a major exporter can tighten global supply overnight.
Gold's different role
Gold behaves less like an industrial input and more like a store of value. Industrial demand for gold is modest compared to its use in jewelry, central bank reserves, and investor portfolios seeking a hedge against inflation or currency weakness. That is why gold often rallies during periods of financial stress or falling real interest rates, even when broader industrial commodities are flat or falling — it is trading on a different set of expectations than a barrel of oil.
How most investors get exposure
Very few individual investors take delivery of actual barrels of oil or bushels of corn. Instead, exposure typically comes through futures contracts, commodity-focused exchange-traded funds, or shares of companies whose earnings are tied to a commodity's price, such as energy producers or miners. Each route carries its own mechanics and risks, but all of them ultimately track back to the same physical supply-and-demand story playing out in the underlying market.

Quick answers
What counts as a commodity?
A raw physical good that is broadly interchangeable regardless of producer, typically grouped into energy, metals, and agriculture.
Why do commodity prices react so fast to weather and conflict?
Because supply is often concentrated in specific regions or seasons, so a disruption — a drought, a hurricane, a conflict near a major producer — can tighten available supply almost immediately.
Why does the dollar affect commodity prices?
Most commodities are priced in U.S. dollars globally, so a weaker dollar makes them cheaper for buyers using other currencies, which tends to support prices, and a stronger dollar tends to weigh on them.
