Module 3 — USDA Data Sources

The entire Basis Brief intelligence pipeline is built on free, publicly available government data. This episode covers the three USDA data sources that matter most — the WASDE, AMS Daily Grain Market News, and NASS Crop Progress — with enough precision that you can read each report the way a practitioner does, not the way a journalist summarizes it.The WASDE section walks through the corn supply and demand balance sheet line by line. By the end of this discussion, you will be able to read a WASDE table, calculate what a yield revision means for total production, and understand why carryout — not the absolute price level — is the number that moves markets.What this episode covers:What WASDE stands for, who produces it, and why it is the most market-moving scheduled government publication in agricultural commoditiesWalking the corn S&D table: Area, Yield, Beginning Stocks, Production, Feed and Residual, FSI (ethanol dominates), Exports, Ending StocksWhy a 1-bushel-per-acre national corn yield revision changes total production by 90 million bushelsCarryout as a days-of-use calculation and why markets trade a risk premium when days of use fall below 30How AMS market reporters collect daily cash price data at hundreds of locations — and what geographic coverage gaps mean for your basis calculationNASS Crop Progress: what Good/Excellent percentage means, why the same rating means different things at different crop development stagesWhy the Crop Progress report matters more in late June than in SeptemberOperational note: how USDA data disruptions in 2025–26 affect pipeline design and fallback data sourcingBasis Brief delivers automated weekly grain basis analysis and WASDE intelligence to grain elevator operators, ag lenders, and feed mill managers across the Corn Belt.
