A New Futures Contract for the Sorghum-Corn Spread

Sorghum and corn prices move together, but not in lockstep (Figure 1A). For a sorghum producer, the spread between them can matter as much as the direction of corn prices. Since 1989, the monthly spread has ranged from a $1.72 discount to a $1.47 premium, and the largest swings have come recently (Figure 1B). In June 2026, sorghum averaged 17 cents above corn, yet USDA’s 2025/26 season-average estimates imply a 60-cent discount for the year. Relative prices can change that fast.

A sorghum grower faces two price risks. The first is the broad grain-price risk sorghum shares with corn, and corn futures have long served as the cross-hedge. The second is the risk that sorghum moves against corn, widening or narrowing the spread. Nothing has priced that one. On August 24, 2026, CME Group listed a contract that does (CME Group 2026a).

Export exposure is a major driver of spread moves. USDA estimates 2025/26 exports at 210 million bushels against 230 million bushels of domestic use, so exports account for about 48 percent of the two combined (Figure 2). For 2026/27, USDA projects 170 million bushels of exports and 140 million bushels of domestic use. The export share rises to 55 percent even though exports fall, because domestic use falls farther.

Historically, a higher export-to-domestic-use ratio has come with a stronger sorghum price relative to corn. From 2006/07 through 2024/25, moving that ratio from 1.0 to 2.0 was associated with a 27-cent-per-bushel improvement in the spread, and the relationship accounts for 57 percent of the variation in price (Figure 3). It is descriptive, not causal. Production, freight, trade policy, and feed demand all move both exports and domestic use. The 2025/26 estimate sits about 34 cents below the fitted line, a reminder that the ratio measures exposure rather than a complete pricing model.

Sorghum futures (MILO) trade as a differential to CBOT corn rather than as a flat price, the first sorghum contract since the Kansas City Board of Trade delisted its own in 1999. The two risks come apart. Corn futures manage the level. MILO manages the spread.

Consider a grower expecting to sell 50,000 bushels. Ten MILO contracts match that volume. A grower who fears sorghum will weaken relative to corn sells MILO. A 30-cent decline in the spread would cut the crop’s relative value by about $15,000, and a 30-cent decline in MILO would return about that much on the short position, before commissions and residual basis risk.

One caution about the word basis. MILO prices the sorghum-corn differential, not a local cash basis, and it settles to no cash index. Settlement is by physical delivery of sorghum to exchange-approved elevators in Kansas City, Wichita, Hutchinson, and Salina at a 6 to 12 cent discount per bushel (CME Group 2026b). There are no delivery point in the South. MILO will converge to an interior Kansas spread set by feeders and ethanol plants, while much of the region prices against Gulf export loadings. Whether the two track closely enough to hedge is an open question, and one that groups like the National Sorghum Producers has been raising.Liquidity will decide the rest. Producers with grain to sell are natural short hedgers. Feeders, ethanol plants, and other end users are natural longs. Merchandisers and exporters may take either side. If participation generates sufficient trading volume, open interest, and two-sided liquidity, sorghum gains a public price for a risk that has never had one. If it doesn’t, that poses a whole new set of risks for growers.

Note: USDA estimates 2025/26 exports at 210 million bushels against 230 million bushels of domestic use, a 48 percent export share. For 2026/27, it projects exports of 170 million bushels and domestic use of 140 million, a 55 percent share. Hatched bars mark the estimate and the projection. The black line, read against the right axis, shows exports as a share of domestic use plus exports.

Note: Ordinary least squares fit on actual observations for 2006/07 through 2024/25, with a 95 percent confidence band. Moving the ratio from 1.0 to 2.0 lifts the fitted spread 27 cents per bushel, from a 24-cent discount to roughly break-even. R² of 0.57. The fitted spread crosses zero at a ratio of 1.88. The 2026/27 projected ratio of 1.21 implies an 18-cent discount, within two cents of USDA’s own forecasts of $4.30 for sorghum against $4.50 for corn. The 2025/26 estimate and 2026/27 projection are shown as open markers and are not used in the fit. The relationship is descriptive, not causal.
