Soybeans

A soybeans — a legume crop producing protein-rich meal and oil — are grown on 120+ million hectares globally and produce two major commodities: soybean meal (animal feed) and soybean oil (cooking oil, biodiesel). The crop is typically rotated with corn in North America. China imports 60%+ of global soybean exports, creating enormous price leverage via Chinese policy and demand shocks.

The protein crop

Soybeans are grown primarily for their protein-rich meal, which is the primary protein source for animal feed globally. Soybean meal replaces corn in animal feed, particularly for poultry and cattle, providing the amino acids required for rapid growth.

Soybean oil is a byproduct of meal production and is used for cooking oil, margarine, and increasingly as a feedstock for biodiesel.

Crop rotation with corn

In North America, soybeans and corn are typically rotated annually. A field planted with corn one year is planted with soybeans the next. This rotation is agronomically beneficial: soybeans fix nitrogen from the air (via symbiotic bacteria), reducing the need for synthetic nitrogen fertilizer.

Planting decisions for soybeans versus corn are made based on expected prices. High soybean prices relative to corn incentivize soybean plantings; low soybean prices reduce plantings.

This creates a linked dynamic: when corn prices are high, corn plantings increase and soybean plantings fall; when soybean prices are high, the reverse occurs.

China’s import dependency

China imports 60–70% of global soybean exports, using them for animal feed (primarily pigs). China produces soybeans domestically but at yields 30–40% lower than the US, making imports essential.

This dependency gives China enormous leverage: by cutting soybean imports (as a trade war tactic), China can crash global soybean prices, harming US and Brazilian farmers.

Conversely, if China suddenly increases soybean demand (expanding pig production), global soybean prices spike immediately.

Weather and South America risk

US soybeans are harvested Sept–Oct. Brazilian soybeans are harvested Jan–Mar. This timing diversity means global soybean supply has a longer window than corn, with production flowing continuously.

However, weather in both US and Brazil affects prices. A drought in the US reduces harvest; a drought in Brazil does the same. A simultaneous drought in both regions creates a global supply crisis.

Biodiesel and policy support

Soybean oil is used as a feedstock for biodiesel, a renewable fuel blend into diesel. US biodiesel policy (tax credits, blending mandates) has driven demand for soybean oil, supporting prices.

However, biodiesel mandates are politically contentious (taking food crops for fuel, raising food prices) and vulnerable to policy change.

Processing and price spreads

Soybeans are processed into meal and oil. The “crush spread” — the profit from buying soybeans and selling the output (meal + oil) — reflects processor profitability.

A wide crush spread incentivizes processing; a narrow spread causes processors to reduce capacity. Traders actively trade the crush spread, betting on processing profitability.

How soybeans trade

Soybean futures trade on CBOT alongside corn and wheat, with high liquidity and tight spreads. Contract size is 5,000 bushels.

Retail access is via commodity-index funds or agricultural ETFs. Direct futures trading is suitable only for experienced traders.

Long-term outlook

Soybean demand is expected to grow 1–2% annually, driven by emerging-market meat consumption and expanded pig farming in China.

Supply growth is constrained by land availability; expanding soybean acreage requires clearing forest (particularly in South America), creating environmental pressure.
