South Dakota corn and soybean prices follow Minneapolis cash markets. Livestock (beef cattle, hogs) demand provides local support for corn prices.
Understanding South Dakota Grain Basis
Basis is the difference between the local elevator cash price and the nearest CME futures contract. Basis tells you how your local market is priced relative to the national benchmark.
Eastern South Dakota basis runs 20–35¢ negative on corn. Western South Dakota can see 40–60¢ negative basis due to higher freight costs.
A strengthening basis (cash rising relative to futures) signals strong local demand — typically from nearby ethanol plants, feed mills, or export elevators bidding aggressively for grain. A weakening basis signals local oversupply or reduced demand. Watch for basis moves of 10¢ or more in a single week as an actionable signal.
