Corn Basis Holds Steady While Soybean Basis Shows Wider Swings

Posted Mar 16, 2026 3:30 PM

Corn basis levels across much of the Eastern Corn Belt have remained relatively steady in recent weeks, while soybean basis has shown greater volatility across the region, according to a new market update from Purdue University’s Center for Commercial Agriculture.

As grain markets transition to May futures contracts, local corn bids have held firm in many areas, with particularly strong basis levels reported in parts of Indiana and Ohio. Soybean basis, however, has varied widely between regions, with some districts experiencing weaker bids as processors adjust demand. The report notes that ethanol plants have continued to offer competitive premiums for corn relative to nearby elevators, supporting local cash prices in some markets. At the same time, soybean crush plants have softened bids in several areas, contributing to the uneven soybean basis environment.

Agricultural economists say tracking local basis remains critical for marketing decisions because regional demand from ethanol plants, processors and exporters can create significant differences in cash grain prices.
