I. Introduction

1. Origin and Position in the Global Food System

Corn (Zea mays L. ssp. mays) Zea mays L. ssp. maysa member of the Poaceae family, originates from Central America and was domesticated by humans thousands of years ago, becoming one of the world’s staple cereal crops. Corn currently holds the largest production volume among cereals, with global output for 2024 estimated at approximately 1.20–1.22 billion tons, and forecasts for the 2025/26 season exceeding 1.26 billion tons, surpassing the individual production of wheat and rice, and representing the majority of total global cereal production.

Corn is cultivated in over 170 countries and territories, with the largest production regions in North and South America, China, and the European Union. The United States remains the world’s largest corn producer, with an annual output of approximately 380–402 million tons, equivalent to 30–32% of total global production, followed by China, Brazil, Argentina, and EU countries such as France.

Biotechnology has shaped corn production in many regions, particularly in the U.S., where genetically modified (GMO) corn varieties account for 80–90% of planted acreage in 2024.

Corn plays a crucial role in both economic development and food security. Beyond direct human consumption, most corn production is used for animal feed, ethanol biofuel production, and industrial products, contributing significantly to global food and livestock supply chains.

2. Role and Applications

Role in Food-Energy Chain:
Role:
Corn is a strategically important crop in agriculture, industry, and the global food-energy chain. Worldwide, approximately 60–65% of corn is used for animal feed, forming the foundation for meat, egg, and dairy production; a smaller portion is used directly as human food; and 15–20% is applied in industrial processing, including food, chemicals, and biofuel (ethanol) production. Its versatility makes corn not only an essential food crop but also a strategic raw material connecting food security, renewable energy, and economic growth

Applications:

• Human Food: Corn and corn-based products are staple foods in many African, Latin American, and Asian countries, providing roughly 21% of global caloric intake, particularly important in rural areas.
• Animal Feed: Corn is the primary ingredient in livestock, poultry, and aquaculture diets, accounting for approximately 60–61% of global corn production, underpinning meat, egg, and dairy production.
• Industrial Raw Material: Corn is widely used to produce starch, glucose syrup, corn oil, confectionery, alcohol, and chemical products for the food, pharmaceutical, and processing industries
• Biofuel (Ethanol): Corn is the main feedstock for ethanol production. In the U.S., about 40% of domestic corn production is used for ethanol, highlighting its strategic role in energy security.
• Export Commodity: Corn is among the most actively traded agricultural commodities globally, generating significant foreign exchange revenue and maintaining strong international competitiveness.
• Fresh Food: Young corn is consumed as fresh food, rich in vitamins and minerals, popular in many regions.
• Strategic Importance: Due to its versatility and high economic value, corn is a strategic raw material, closely linking food security, energy, and global economic development.

II. Global and Vietnamese Corn Production, Export, and Import

1. Production and Stock Levels

The United States, Brazil, and Argentina are the top three global corn exporters, playing a key role in shaping global supply, demand, and pricing. During 2024–2025, these three countries, along with Ukraine, account for approximately 82% of global corn exports, with the U.S. and Brazil each contributing 26–27%, and Argentina about 12%. Due to this concentration, harvest cycles, weather, and agricultural policies in these countries directly influence international corn prices. Global ending stocks are estimated at 287–290 million tons, serving as a market buffer but remaining sensitive to changes in production or exports from the U.S., Brazil, and Argentina.

2. Export

Global corn exports are concentrated in leading countries: the U.S., Brazil, Argentina, Ukraine, and the European Union. According to 2024 statistics: The U.S. leads with ~31.5% of global corn export value. Brazil accounts for ~18%, Argentina ~14.4%, and Ukraine ~11–12%. EU countries such as France, Romania, and South Africa contribute smaller shares but remain significant exporters.

The top 10 exporting countries account for over 90% of total international corn trade, indicating a highly concentrated market.

3. Import

Major global corn importers include Mexico, Japan, China, South Korea, Vietnam, and Egypt, reflecting high demand for animal feed, food production, and domestic consumption. In 2024: Mexico accounted for ~11.1% of global corn import value. Japan ~7.7%, China ~7.4%, South Korea ~5.6%, Vietnam ~4.9%, Egypt ~3.5%.

In Vietnam, corn remains a strategic import commodity due to high domestic livestock industry demand. During the first 6–8 months of 2025, Vietnam imported 4.4–4.7 million tons of corn, valued at USD 1.15–1.73 billion, primarily for animal feed and livestock production. Argentina supplied ~50–55% of Vietnam’s imports (~2.3–3.72 million tons, USD 611–947 million). Brazil accounted for ~22–22.6% (~1–1.48 million tons, USD 250–368 million). Other sources such as Laos, Thailand, and India contributed minor shares.

III. Factors Affecting Corn Prices

1. Global Supply and Demand: Demand is the primary driver of corn prices. Excess supply with low demand reduces prices; high demand with limited supply increases prices.

Projected global production for 2025–26: ~1.297 billion tons.

2. Ethanol Market: Biofuel demand and related policies significantly impact corn prices. Growth in ethanol demand in major economies (U.S., China, India) supports corn prices, while fuel market instability may have the opposite effect.

3. Crude Oil Prices: Higher oil prices make ethanol more attractive → increasing corn demand; lower oil prices have the reverse effect. 2025 price range: ~USD 60–80/barrel.

4. Impact of China: China, a major ethanol consumer and importer, significantly influences global corn demand.

5. Weather and Climate Change: Droughts, excessive rainfall, or La Niña/El Niño events affect precipitation, directly impacting yield and corn price volatility.

6. USD Exchange Rate Fluctuations: Corn is priced in USD. A stronger USD makes corn more expensive for foreign buyers → reducing import demand and potentially lowering prices, and vice versa.

7. Competition from Alternative Crops: Soybeans compete for planting area and usage, affecting corn supply and prices.

8. Logistics and Supply Chain Costs: Transportation, storage, import/export tariffs, and regional production quality influence corn prices.
