basis
Corn basis remains steady across much of the Eastern Corn Belt as markets transition to May futures contracts, with particularly strong local basis levels in central Ohio and northern Indiana. Meanwhile, soybean basis shows significantly more volatility, with widening spreads across districts and notable weakness in Iowa. Ethanol plants continue to offer firm premiums relative to local delivery points, while soybean crush plant basis has softened in several states. Producers can use the Purdue Center for Commercial Agriculture’s Crop Basis Tool to compare local ethanol and crush plant basis levels and evaluate current pricing opportunities against historical averages.
Read MoreCorn and soybean basis levels have improved across much of the Eastern Corn Belt in early 2026, though large regional differences remain. Learn what’s driving basis strength—and how to track your local opportunities using Purdue’s Crop Basis Tool.
Read MoreLocal corn basis across the Eastern Corn Belt has become more volatile, with regions like Indiana and Ohio showing continued strength to March futures, while parts of Illinois have seen weakening. In contrast, soybean basis has stabilized and remains below recent averages in much of the region. Historical patterns suggest basis volatility may ease as we head into the new year — but mixed signals from certain areas warrant close monitoring. Full regional breakdowns and charts are available in the complete article.
Read MoreCorn and soybean basis have strengthened post-harvest in the Eastern Corn Belt, particularly in Indiana and Ohio, while Iowa lags behind. As winter sets in, historical patterns suggest basis levels will stabilize — but regional deviations highlight the importance of local tracking.
Read MoreAs corn and soybean harvest progress across the country, recent basis movements have pushed nearby basis levels above their historical averages in much of the Eastern Corn Belt. Typically, basis weakens through harvest, with nearby basis levels often bottoming out between mid-October and November. This marketing year, however, corn and soybean basis began below the two- and three-year averages, respectively, and recent movement has flipped the relationship in many USDA crop reporting districts.
Read MoreFor much of the 2024-2025 marketing year, the basis for both corn and soybeans looked much different than their historical averages. Both crops started well below what previous trends would suggest.
Read MoreOn Tuesday, the August WASDE report was released, which significantly increased the projected 25/26 corn supply and decreased the soybean supply. There were immediate effects in the futures market. September and December corn futures dropped by $0.13/bu, and September and November soybean futures increased by $0.21/bu. As we approach harvest, it is yet to be seen how this will affect the new crop basis.
Read MoreAt the time of our last basis update in the second week of June, the regional soybean basis was highly volatile. This volatility was driven by sharp decreases in basis at soybean processors in Ohio, Illinois, and Indiana. As June continued, the sharp decrease in soybean basis continued and spread across the entire Eastern Corn Belt. However, as we have progressed through July, much of the basis decrease has been recovered.
Read MoreAs July futures near expiration, corn basis across the Eastern Corn Belt continues to strengthen. In Central Ohio, the basis has improved by $0.12/bu over the past three weeks to $0.26/bu, reaching a ten-year high for the second week of June.
Read MoreThe corn and soybean basis across the Eastern Corn Belt have strengthened for three straight months. As a result of the increasing trend, multiple cash bids across the region are now higher than the July futures price (i.e., basis to July futures is positive). The consistent strengthening has also led to many local basis levels reaching their highest mark of the 2024 – 2025 marketing year.
