Sorghum

Sorghum is the great invisible grain of the Western world. It is the planet's fifth most important cereal, after corn, wheat, rice, and barley, with world production of roughly 60 million tonnes a year, and it feeds more than 500 million people across Africa and Asia, yet most Americans and Europeans have never knowingly eaten it. That is because the crop lives a double life. In Africa and India it is a direct human food staple, ground for porridge, flatbreads, couscous, and traditional beer; in the rich world it is animal feed, ethanol, and an export crop, almost never sold for people to eat.

The plant explains the split. Sorghum (Sorghum bicolor), called milo in the US grain trade, is a tough, drought- and heat-tolerant grass that yields where corn would wither, so it is the dryland cereal of the southern US Plains, the African Sahel, and semi-arid India. Domesticated in the Sudan-Ethiopia region some 8,000 years ago, it is one of humanity's oldest crops. It is naturally gluten-free, which has given it a small but growing Western health-food following, and sweet-sorghum varieties are pressed for syrup while others are grown for forage; but those are niches against its dominant roles as feed grain and food staple.

Sorghum has no futures market, and the reason is corn. US milo is priced and hedged as a corn substitute, valued at roughly 90 percent of the corn price as a feed grain, so the deep CBOT corn contract already does the hedging job and a standalone sorghum future has nothing to add. One was tried: grain sorghum futures traded thinly on US exchanges from the mid-twentieth century and the Kansas City Board of Trade relaunched a contract in 1989, but the rise of unit "shuttle trains" rerouted the physical trade away from the terminal market and the contract died for lack of liquidity. A small, geographically concentrated crop priced off corn and dependent on one foreign buyer never sustained a two-sided market.

That one buyer is China, which has taken more than 80 percent of US sorghum exports in recent years, for animal feed and, distinctively, for baijiu, the sorghum-distilled spirit that is the best-selling liquor category in the world by volume. The dependence cuts both ways. When China buys, milo trades at a premium over corn; when China retreats, it collapses to a discount, and the swings are violent: a 70-cent-per-bushel premium over corn in August 2024 became a roughly 60-cent discount by early 2025 as Chinese demand dried up under new tariffs. The US is the largest exporter, with Australia and Argentina behind it, but the price of an American sorghum crop is set as much in Beijing as on the farm.
