USDA WASDE and crop report markets
Grain and oilseed markets move on a handful of US government reports, and event contracts sometimes ask about the numbers in them directly: will the projected US corn yield exceed a level, or will soybean ending stocks come in below a threshold. Commodity futures traders have watched these releases for generations, but the reports have a vocabulary of their own. This SoftCta guide explains which report contains which number, so a reader can match a contract to the right line of the right table.
WASDE in one page
WASDE is a monthly set of balance sheets. For each crop it lists beginning stocks, production, imports, domestic use, exports and ending stocks for the current and coming marketing years, along with projected average farm prices. It also covers world totals and major exporters. It is released around the tenth of the month at noon Eastern time, with a published schedule for the year.
Survey numbers versus projections
Production and yield in the US come from NASS surveys of farmers and, later in the season, field measurements. Early in the year USDA uses trend yields because there is no crop yet. The shift from trend to survey estimates in late summer is when yields can change sharply. A contract on yield should name the crop, the units (bushels per acre for corn and soybeans) and the specific report month.
Ending stocks as a residual
Ending stocks absorb every other change in the balance sheet. A lower export forecast raises them; a lower yield cuts them. Because of that, ending stocks can move even in a month when production is unchanged. Readers sometimes treat a stocks surprise as a production surprise; read the full sheet before drawing a conclusion. Our consensus guide explains why analyst survey averages are not probabilities.
Acreage and stocks reports
Prospective Plantings, Acreage and quarterly Grain Stocks are separate NASS releases. They have their own surprise history and settle different questions. Weather risk overlays all of them; our drought monitor guide covers how dryness is measured officially.
Prices versus data
Futures on the CME are about prices for delivery; a WASDE contract is about a published number. They are linked but not the same. Our commodity futures versus event contracts guide explains the difference in structure and risk.
Rounding and revisions
USDA reports figures to set precision, such as one decimal for yields and million bushels for stocks. Each month's report revises the last. Most contracts settle on the named month's report and ignore later changes, but confirm the rule and the rounding precision.

Reading the quote step by step
- Read the full title and rules, including the named settlement source and the time zone.
- Convert the Yes and No prices to implied probabilities and note the gap between them.
- Subtract fees and spread to see the effective price you would actually face.

- Convert prices with fee and spread awareness; verify live cents on the operator.
- Prefer primary settlement sources over secondary headlines and social summaries.
- Treat ChanceWire hubs, movers, and tools as orientation — not order entry.
- Confirm age, location, and product eligibility; SoftCta pages will not suggest location spoofing.
- If clarity is incomplete, watching is a complete SoftCta outcome — no pick-selling urgency required.
SoftCta habits
- Write your own probability range before checking the crowd price.
- Prefer dated primary sources over social summaries.
- Compare related markets when a single book looks extreme.
- Size curiosity with fees and depth in mind; substantial risk of loss.
FAQ
- What is WASDE?
- The World Agricultural Supply and Demand Estimates report is published monthly by the US Department of Agriculture. It gives supply and use balance sheets for major crops in the US and around the world.
- What is the difference between WASDE and NASS Crop Production?
- The National Agricultural Statistics Service publishes survey-based crop production and yield estimates, often on the same day. WASDE uses those figures in its balance sheets and adds demand, trade and ending stock projections.
- What are ending stocks?
- Ending stocks are the projected amount of a crop left over at the end of a marketing year. They are a balance-sheet residual, so changes in production, exports or domestic use all move them.
- Which reports besides WASDE matter?
- Prospective Plantings at the end of March, Acreage at the end of June and the quarterly Grain Stocks reports are closely watched and can produce large price moves.
