What This Indicator Measures
Weekly FOB Upriver (Paraná River terminals) export price for Argentine corn in USD/mt.
Corn / Maize: A weekly physical export price for corn of a stated origin and grade (US 2YC/3YC = No. 2 / No. 3 yellow corn).
What the source does not state for this series
- No grade is printed for this series.
Specification · product family only
- 2YC and 3YC are US grades No. 2 and No. 3 yellow corn.
Basis: FOB Upriver
- FOB (free on board): the price covers the product loaded on the vessel at the named origin; sea freight and insurance to the destination are excluded, so FOB values from different loading areas are not delivered-cost equivalents.
- Argentina Upriver refers to export terminals on the Paraná River (Rosario area) reached via the river channel, with draft limits that affect vessel size.
Unit: USD/mt
- All grain and feed series are USD per metric tonne on the stated port basis.
- Weekly assessments: the change shown is between two weekly readings, never a daily move.
