Crops: Basis & Basis Deviation Maps

Basis maps are a spatial representation of crop basis in Kansas, Nebraska, Missouri, Oklahoma, and parts of Colorado and Texas (depending upon crop).  Basis is calculated by subtracting the nearby futures price from the cash price.  Basis deviation maps show the difference between current basis and the average of the three previous years for the same week.  Maps are updated monthly using cash and futures prices from the first Wednesday of the month.
