Corn Bar Chart: Understanding Corn Price Movements and Patterns


Corn is one of the world’s most frequently farmed crops, and its significance in the global economy cannot be emphasized. It is utilized in a variety of applications, including food, feed, fuel, and industrial production. 

As a result, maize prices have a large impact on many sectors of the economy, and knowing corn price trends and patterns is critical for farmers, traders, and policymakers alike. 

A corn barchart, which depicts the price of maize over time in a graphical manner, is one approach to visualize these trends and patterns.

The United States is the world’s greatest corn producer, with approximately 96 million acres dedicated to maize cultivation. Corn, in fact, is the most produced crop in the country, with an annual output of more than 14 billion bushels. 

Because of its large-scale production, the country has become a prominent player in the global maize market, with exports accounting for a significant portion of overall production.

Corn’s importance to the American economy cannot be emphasized. It is not only a significant source of income for farmers, but it is also used in a variety of businesses including as food and beverage, ethanol manufacturing, and animal feed. In actuality, around 40% of the corn output in the United States is used for ethanol production, with the remainder being used for human and animal use, as well as exports.

Corn Price Influencing Factors

Corn prices are influenced by supply and demand, just like any other commodity. But, there are a number of additional factors that might affect corn supply and demand, and thus its price. Among these elements are:

  • Corn is a weather-sensitive crop, and bad weather conditions such as droughts, floods, or excessive temperatures can have a considerable impact on corn production, affecting corn supply and demand.
  • Ethanol demand: Corn is the major feedstock for ethanol production, therefore ethanol demand can influence corn demand.
  • World economic conditions: Economic conditions in major maize-consuming countries such as China or the United States can have an impact on corn consumption.
  • Trade policies, such as tariffs or subsidies, can have an impact on maize supply and demand through changing the flow of corn exports and imports.
  • Government measures, such as subsidies or requirements for ethanol production, can also have an impact on maize consumption.
  • Crop acreage and yields: The quantity of land dedicated to corn production, as well as the yield per acre, can influence supply and, hence, corn price.

The Fundamentals of Bar Charts

Before we get into analyzing a corn bar chart, let’s go over the fundamentals of bar charts. A bar chart is a graphical representation of data in which bars represent variable values. 

The height of each bar in a bar chart shows the variable’s value, and the bars are often placed along the x-axis, which represents time or another categorical variable.

Depending on the orientation of the bars, a bar chart might be vertical or horizontal. The most common sort of bar chart is a vertical bar chart, which is used to show changes in a variable over time or across categories. 

When there are too many categories to display on a vertical bar chart and the categories are too long to fit on the x-axis, a horizontal bar chart is utilized.

Understanding a Corn Bar Chart

Now that we’ve covered the fundamentals of bar charts, let’s look at a corn bar chart and how to interpret it. The following is a fictitious corn bar chart depicting the price of maize from October 2022 to March 2023:

The x-axis in this chart depicts time, and the y-axis represents maize prices in US dollars per bushel. Each bar reflects the average monthly corn price for that month. The price of corn is represented by the height of the bar, and the color of the bar indicates whether the price increased or dropped from the previous month. A green bar shows an increase in price, whereas a red bar suggests a fall in price.

The graphic shows that the price of corn has been quite variable during the last decade. Many periods of rapid price spikes and decreases have occurred, which can be ascribed to a variety of factors such as poor weather conditions, changes in trade regulations, and swings in demand.
