Commodities: What They Are and Why They Matter


Every day, people use or consume things made from basic raw materials—things like oil, coffee, wheat, and gold. These raw materials are called commodities, and they are a very important part of the world economy. Even though many people don’t realise it, commodities affect the price of petrol, food, and even electricity. They are also traded like stocks or shares, and many people invest in them to try to make money or protect their savings from inflation.

This article explains what commodities are, how they are traded, why they are important, and how beginners can get started with investing in them. Everything is written in a simple and clear way, using examples that help make difficult ideas easier to understand.


1. What Are Commodities?

Commodities are natural or basic products that come from the earth or from farms. These products are used to make other goods or services. Commodities are the starting point of many things we use in daily life. They are usually the same no matter who produces them. This means that one bag of coffee beans is basically the same as another bag of coffee beans, even if they come from different farms.

There are two main types of commodities:

  • Hard commodities: These come from mining or extraction. Examples include gold, silver, oil, and natural gas.
  • Soft commodities: These are grown or raised, like wheat, corn, coffee, cotton, and livestock (such as cows and pigs).

Let’s take wheat as an example. Wheat is a soft commodity. It is grown on farms and then sold to food companies that use it to make bread, pasta, and many other products. When the price of wheat goes up, the cost of bread in the supermarket may also go up.


2. How Are Commodities Traded?

Commodities are bought and sold on special markets called commodity exchanges. These are places where people trade large amounts of raw materials. Some well-known exchanges include:

  • Chicago Mercantile Exchange (CME)
  • New York Mercantile Exchange (NYMEX)
  • London Metal Exchange (LME)

There are two main ways to trade commodities:

  • Spot trading: This means buying or selling the commodity for immediate delivery.
  • Futures trading: This means agreeing to buy or sell a commodity at a set price on a future date.

Futures trading is more common, especially for people who invest in commodities. It allows buyers and sellers to fix the price in advance, which can help avoid sudden price changes.

Here’s an example: Imagine a coffee company wants to make sure it can buy coffee beans in three months at a certain price. It enters into a futures contract to buy the coffee at today’s price, even though the delivery will happen later. This helps the company plan its budget without worrying about sudden price jumps.

Some investors also use ETFs (Exchange-Traded Funds) to invest in commodities. These are like baskets of investments that follow the price of a commodity. ETFs are simple to buy and sell and are available through stock trading platforms.


3. Why Are Commodities Important?

Commodities are very important for every country and every person. Without commodities, people would not have access to petrol, food, electricity, or basic building materials.

Many countries depend on selling commodities to earn money. For example, oil is the biggest export for countries like Saudi Arabia. If oil prices go up, the country earns more money. If prices fall, the economy might struggle.

Commodities also affect everyday life. When oil prices rise, the cost of petrol and transport increases. This affects the price of food, clothes, and anything that must be delivered. When wheat or corn prices rise, food becomes more expensive. This is why governments and businesses watch commodity prices closely.

Commodities are also important for investors. Many people invest in commodities to protect their money from inflation. Inflation means that the value of money goes down, and prices go up. Commodities usually rise in value during inflation, so they can help investors keep their money safe.


4. What Makes Commodity Prices Go Up and Down?

Commodity prices change all the time. This is called price volatility, and it happens for many reasons. The most common reasons are:

  • Supply and demand: If there is more supply than demand, prices go down. If there is more demand than supply, prices go up. For example, if a drought ruins wheat crops, the supply drops, and prices go up.
  • Weather and natural disasters: Floods, storms, or droughts can destroy crops or slow down mining and oil production, which affects supply.
  • Political events: Wars or conflicts in countries that produce a lot of oil can cause prices to rise.
  • Currency changes: Commodities are usually priced in U.S. dollars. If the dollar becomes weaker, it may cost more for countries using other currencies to buy those commodities.
  • Investor speculation: Sometimes, prices rise or fall because investors think something might happen—even if it hasn’t happened yet. This can make prices go up and down quickly.

Let’s look at an example to understand this better: Imagine Peter, who reads that a storm is coming to Brazil, one of the biggest coffee-producing countries. He thinks that the storm will damage the crops and reduce supply. So, he buys coffee futures, hoping the price will rise. If the storm hits and damages the coffee farms, the supply drops and prices rise. Peter can then sell his futures for a profit. 

But if the storm misses the farms and the coffee supply is not affected, prices might fall, and Peter could lose money.


5. How to Start Investing in Commodities

For someone new to investing, there are several simple ways to get started with commodities:

  • Commodity ETFs: These are easy to buy through online brokers. They track the price of one or more commodities, such as gold, oil, or agriculture.
  • Stocks of commodity companies: These are shares of companies that produce commodities, like mining companies or oil firms. Their stock prices often follow commodity prices.
  • Mutual funds: Some mutual funds invest in commodities or in companies that deal with commodities.
  • Precious metals: Some people buy gold or silver as a safe place to keep money. These metals are easy to store and sell when needed.

It is important to understand that investing in commodities involves risks. Prices can go up and down very quickly. It is a good idea to start small, do research, and not invest money that cannot be lost. Many investors use commodities as part of a larger portfolio, not as the only investment.

For complete beginners, starting with a gold or silver ETF is often the easiest option. It gives exposure to the commodity market without needing to learn about futures contracts or commodity exchanges.

Commodities are all around us, from the petrol in cars to the coffee in a morning cup. They are the building blocks of life and the global economy. For investors, commodities offer both opportunity and risk. With a basic understanding of how they work and why they matter, even someone with no experience can begin to explore the world of commodity trading and investing.
