A commodity is a raw material or basic agricultural product that is interchangeable with the same product from any other producer. One barrel of a given crude grade is the same as another. One bushel of a given wheat grade is the same as another. That interchangeability is the whole point: it lets these goods be bought and sold by specification rather than by brand.
The prices that define this market move constantly. As of mid-October 2026, Markets Insider listed WTI crude near $95.35 a barrel, gold near $4,080 a troy ounce, and copper near $14,741 a ton, alongside dozens of other quoted contracts. Those numbers shift by the minute, but the categories behind them do not. This article defines what counts as a commodity, how the market sorts them, and why the prices set there show up in everyday spending.
What makes something a commodity rather than a product?
Two conditions define a commodity. First, it must be fungible, meaning any unit meets the same specification as any other unit. Second, it must be traded on the basis of that specification, not on who produced it. Nobody pays a premium for "Exxon copper" or "Iowa corn" as such; the market prices copper and corn by grade, purity, moisture content, or location.
That is the dividing line between a commodity and a product. Coffee beans are a commodity. A roasted, branded bag of that coffee on a supermarket shelf is a product, priced on brand and convenience. Lumber is a commodity; a finished kitchen cabinet is a product. The transformation from one to the other is where most of an economy's margin lives, which is why commodity prices matter mainly as inputs.
Standardization is what makes large-scale trading possible. Exchanges publish contract specifications that state exactly what qualifies for delivery: which crude grades, what metal purity, what grain moisture. A buyer can take delivery without inspecting the specific lot, because the specification does the inspecting for them.
What are hard commodities?
Hard commodities are natural resources that are mined or extracted. The category splits into three familiar groups: energy, precious metals, and industrial metals.
Energy covers crude oil, natural gas, gasoline, heating oil, and coal. These are the largest commodity markets by trading volume, and they touch nearly every other price in the economy through transport and manufacturing costs. Precious metals include gold, silver, platinum, and palladium, which trade both as industrial inputs and as stores of value. Industrial metals include copper, aluminum, nickel, zinc, tin, and lead, and their prices tend to follow construction and manufacturing demand.
The current quote boards show how broad this group runs. Trading Economics tracks everything from uranium and coking coal to lithium, iron ore, and cobalt hydroxide, alongside the traditional copper and aluminum contracts. The industrial category has widened as electrification and battery supply chains have pulled more specialty materials into exchange-traded or actively quoted territory.
What are soft commodities?
Soft commodities are grown, not mined. The classic list is coffee, cocoa, sugar, cotton, and orange juice, but the agricultural category is much wider: wheat, corn, soybeans, rice, oats, canola, palm oil, and rapeseed all trade as standardized contracts. Livestock is usually grouped here too, with live cattle, feeder cattle, and lean hogs quoted alongside the crops.
Softs differ from hards in one important way: their supply is seasonal and weather-dependent. A mine can run year-round; a coffee harvest cannot. That is why soft commodity prices are prone to sharp moves when a growing season goes wrong, and why a single government crop report can reset prices across the world's grain markets in one morning. We covered a connected angle in How Does One USDA Report Set Grain Prices Around the World?.
The hard-soft line also explains different price behavior over time. Metals can be stored indefinitely and recycled, so supply is relatively durable. Crops perish or degrade, so the market has to clear each harvest within a limited window. Storage, spoilage, and seasonality are why the two halves of the commodity market attract different kinds of traders and different kinds of risk.

How does a commodity price actually get set?
Commodity prices come from two connected markets. The spot market is where a physical cargo changes hands now, at a price for immediate delivery. The futures market is where contracts for delivery months or years ahead trade on exchanges, and those contracts are what most quote boards display.
Futures prices are not guesses about the future in the casual sense. They reflect what buyers and sellers will agree to today for delivery later, which bundles together current supply, storage costs, expected demand, and the cost of carrying the goods until the delivery date. When futures trade above spot, the market is effectively paying for storage; when futures trade below spot, the market is paying holders to release supply now. Both shapes carry information, and neither means the market "knows" where prices are headed.
For a closer look at that mechanism in oil, the relationship between spot and futures is worth reading directly, because it is where a lot of commodity-market confusion starts.
Why do commodity prices reach everyday prices?
Commodities are the input layer of nearly everything people buy. Fuel prices flow into shipping and freight, which flow into the shelf price of goods. Grain prices flow into feed, which flows into meat and dairy. Cotton flows into clothing, lumber into housing, copper into wiring and electronics.
The pass-through is rarely one-for-one or immediate, because labor, rent, taxes, and margins sit between the raw material and the receipt. But direction matters: a sustained move in a widely used input eventually shows up downstream, and a spike in a niche input shows up only where that input dominates. A cocoa shock lands in chocolate; a copper squeeze lands in construction and electrical goods.
Our analysis of how these moves propagate suggests readers should watch the breadth of a price move, not just its size. A single commodity jumping on a localized supply event is a story about that commodity. Several energy and metal prices moving together over weeks is a story about the whole cost structure of the economy, and that distinction is where most misreadings of commodity news begin.
What should a reader take from the commodity price board?
Take three things. First, the categories are stable even when prices are not: energy, metals, agriculture, and livestock have traded this way for generations, and knowing which bucket a headline belongs in tells you what kind of supply-and-demand story to expect. Second, the quoted price is a standardized contract price, not necessarily the price a particular buyer pays for a particular lot; basis, freight, and quality adjustments all sit on top.
Third, commodity prices are volatile by nature, and markets built on them can produce large losses as well as gains. That volatility is not a flaw in the system; it is the system doing its job, repricing scarce goods as conditions change. For readers who want to go deeper, the mechanics of trading itself are covered separately, and the specific supply stories behind individual commodities, from OPEC+ quotas to grain reports to the housing-lumber link, each have their own treatment elsewhere on this site.
The definition, in the end, is short. A commodity is a standardized raw material, priced by specification, traded in spot and futures markets, and passed through to consumer prices with a lag and a haircut. Everything else in commodity coverage is a question of which raw material, which season, and which bottleneck.
