What is corn?

Copy link to section

Corn is a grain that has been used as food for humans and livestock for thousands of years. Also known as maize, it’s a key ingredient in hundreds of different food types, cooking oils, and is increasingly being used to create environmentally friendly biofuels.

Its central place in society is what gives corn its value. Even in a globalised world with many different sources of food, a shortage of grain can lead to food shortages. As biofuels start to make up a bigger percentage of overall fuel consumption, the importance of grains like corn is going to grow even further.

The price of corn constantly fluctuates and the biggest impact comes from the supply side, where bad weather or poor harvests can cause shortages that push the price up. Expectations – of good or bad harvests – can also have an influence as corn is often traded a few months in advance of it actually coming onto the market.

The demand for grain comes from all over the world, but can be particularly acute in emerging markets in Asia. Similarly, growth in the renewable energy sector can also increase demand and send the price up.

The corn futures market traces back to the 19th century when the Chicago Board of Trade sought to create price stability for farmers and buyers. Today, corn is one of the most widely traded grains in the world. The United States dominates production and exports nearly a third of its crops to countries like Japan, Mexico, and Colombia. 

Corn futures contracts are traded on the CBOT and other global exchanges. Prices are impacted by weather, biofuel policies, and oil prices. Like other commodities, the price of corn can fluctuate greatly and in the past few years alone has seen a 150% rise followed by a 50% loss. 

While speculators have influenced extreme price spikes and volatility, corn futures markets have brought general price assurance to producers, users and crop-dependent economies over the long run.

Yes, corn is a valuable commodity and there are numerous reasons why investors are attracted to the market. We have highlighted some of these key fundamentals below, explaining what they are and why they matter.

  • Hedge against inflation. Inflation is a risk all investors face, and investing in corn is one way to ‘hedge’ or protect against it. Inflation is when money loses value over time and if inflation rates rise, agricultural commodities, such as corn will likely increase in price too.

Investing in commodities like corn offers a different approach to diversification. Corn is used worldwide in many different ways, and adding it can add safety to your portfolio for when other sectors are underperforming. 
  • Ethanol demand. Ethanol is produced through the fermentation of agricultural products and corn is often used as part of that production. Ethanol has many uses, including transportation fuel and manufacturing. One way to speculate on the rising demand for ethanol is by investing in corn.
