Commodities are raw materials: energy such as crude oil and natural gas, metals such as gold and copper, and agricultural products such as corn, wheat and coffee. Unlike stocks, commodities do not pay dividends or have earnings. Their prices are set by physical supply and demand, by the cost and availability of storage, and by the flows of investors and hedgers in futures markets. Understanding these fundamentals is the starting point for trading commodities. The short introduction is in [What Are Commodities?](https://learn.tradelabsai.com/markets/what-are-commodities/).

## Commodity sectors

| Sector | Examples | Key drivers |
|---|---|---|
| Energy | Crude oil, natural gas, gasoline, heating oil | OPEC+ policy, economic growth, weather, refining |
| Precious metals | Gold, silver, platinum, palladium | Real interest rates, the dollar, safe haven demand, industry |
| Industrial (base) metals | Copper, aluminium, nickel, zinc | Construction, manufacturing, China's economy |
| Grains and oilseeds | Corn, wheat, soybeans | Weather, planting, exports, biofuels |
| Softs | Coffee, sugar, cocoa, cotton | Weather in producing regions, currency moves |
| Livestock | Live cattle, lean hogs | Feed costs, herd cycles, disease |

## Supply and demand basics

Commodity supply is often slow to respond to prices. A new copper mine can take ten years to develop; farmers plant once a season. Demand can also be slow to adjust in the short term, because people still need fuel and food. As a result, small imbalances can cause large price swings, especially when inventories are low.

**Example: A small shortfall, a big move**
Suppose global oil demand is 103 million barrels a day and an outage removes 1.5 million barrels a day of supply, about 1.5%. With inventories already low and little spare capacity, buyers compete for the remaining barrels, and prices might rise 15% to 25% until demand slows or new supply arrives. Economists describe this as low short term price elasticity. The same shortfall when inventories are high might barely move prices. See [Storage and Inventories](https://learn.tradelabsai.com/commodities/storage-and-inventories/).

## Key price drivers

| Driver | Effect |
|---|---|
| Inventories | Low stocks make prices volatile and curves backwardated |
| Economic growth | Strong growth lifts energy and industrial metals |
| US dollar | Commodities priced in dollars tend to fall when the dollar strengthens |
| Interest rates | Higher real rates weigh on gold and raise storage financing costs |
| Weather | Drives crops, natural gas demand and some supply disruptions |
| Geopolitics | Wars, sanctions and export bans disrupt supply |
| Policy | OPEC+ decisions, biofuel mandates, export taxes |
| Investor flows | Index funds and speculators amplify trends |

## Market participants

- **Producers:** farmers, miners, oil companies, who hedge by selling futures.
- **Consumers:** airlines, food companies, utilities, who hedge by buying futures.
- **Merchants and traders:** firms such as large commodity trading houses that move physical goods and arbitrage between locations.
- **Speculators:** funds and individuals betting on price moves.
- **Index investors:** funds tracking commodity indices.

## Key data sources

| Market | Data |
|---|---|
| Oil | US EIA weekly petroleum status report, IEA and OPEC monthly reports |
| Natural gas | EIA weekly storage report |
| Grains | USDA WASDE monthly supply and demand estimates, crop progress reports |
| Metals | LME and COMEX warehouse stocks |
| All futures | CFTC Commitments of Traders positioning |

## How commodities are traded

- **Futures** on exchanges such as CME (NYMEX, COMEX, CBOT), ICE and the London Metal Exchange. See [How Futures Contracts Work](https://learn.tradelabsai.com/futures/how-futures-contracts-work/).
- **Options on futures.**
- **ETFs and ETNs,** which usually hold futures and face roll costs. See [Roll Yield](https://learn.tradelabsai.com/futures/roll-yield/).
- **Shares of producers,** which add company specific risks.
- **Physical markets** for large commercial players.

## The futures curve

Commodity futures curves reflect storage costs and supply tightness. Contango signals ample supply; backwardation signals tightness. The curve also determines roll returns for long term investors. See [Contango](https://learn.tradelabsai.com/futures/contango/) and [Backwardation](https://learn.tradelabsai.com/futures/backwardation/).

## Frequently asked questions

### What drives commodity prices?

Physical supply and demand, inventory levels, economic growth, the US dollar, interest rates, weather, geopolitics and investor flows.

### Why are commodity prices so volatile?

Because supply and demand respond slowly to price changes in the short term, so small imbalances can cause large price moves, especially when inventories are low.

### How do individuals trade commodities?

Mainly through futures, options on futures, ETFs and shares of commodity producers.
