Module 5 — Market Structure and Seasonality

The futures price curve — the relationship between nearby and deferred contract prices — is one of the most information-rich signals available to a physical grain operator, and one of the most consistently ignored by generic market commentary. This episode explains carry markets and inverted markets with enough precision that a practitioner can use the carry spread as a direct input to storage decisions, not just as background context.The episode also covers the crop marketing year structure, the old crop/new crop distinction, and the seasonal basis pattern for corn — the most reliable regularity in agricultural markets and the baseline against which every unusual basis reading should be measured.What this episode covers:The crop marketing year: why corn and soybeans run September 1 through August 31, and what it means for reading WASDE tablesOld crop vs. new crop: why these trade as separate markets with separate futures contracts, and what the spread between them signals about current supply tightnessWhy basis must always be quoted against a specific contract month — and why comparing an old-crop basis to a new-crop basis is meaninglessThe seasonal basis pattern for corn: weakest at harvest (September–November), typically strengthening February through May, and what drives the spring strengtheningCarry markets explained: when deferred futures are priced above nearby, the market is paying you to store — but only if the spread exceeds your actual storage costInverted markets (backwardation) and why they send a direct, physical signal — not a term structure artifact — that a practitioner should respond to by moving grain promptlyThe arithmetic that connects futures carry spreads to elevator storage decisions: a concrete example showing how a $0.08 carry against $0.15 of storage cost produces a guaranteed lossWhy the carry/inverse status of the futures strip should appear in every weekly digest and why transitions between the two are significant eventsBasis Brief delivers automated weekly grain basis analysis and WASDE intelligence to grain elevator operators, ag lenders, and feed mill managers across the Corn Belt.
