The Barchart Corn Price Index family is a series of volume weighted indexes and price assessments that represent fair value pricing for physical Corn across the United States. The indexes are calculated on a continuous basis and use a sophisticated – but transparent - weighting process to ensure prices are objective and reflective of underlying market economics.

Calculated at the County, Crop Reporting District, State, Regional, and National level – from prices contributed by over 4,000 grain buying locations – there are over 800 different front-month indexes. With forward curves going out twelve months for each index area there are over 10,000 objective prices for Corn calculated each day. Historical information is available through to the start of 2014.

Major growing zones are divided among the following regions:

  • Eastern – Illinois, Indiana, Kentucky, Michigan, Ohio, Wisconsin
  • Western – Iowa, Kansas, Minnesota, Nebraska, N. Dakota, S. Dakota
  • Delta – Arkansas, Louisiana, Mississippi, Missouri, Tennessee

The indexes are powered by best-in-class grain prices from Barchart. Additional prices, including basis values and forward curve information, are available exclusively to subscribers of cmdtyView® - the leading platform for commodity trading – or other data products available through Barchart.
