WASDE Endstocks Report (Aug):

Reported vs. Forecast vs. Prior End‑Stocks

Interpretation of US End‑Stocks

• Corn – The reported 1.653 B bushels are below both the estimate (1.737 B) and the previous report (1.790 B). This signals a tighter corn supply than analysts expected.
• Soybean – At 320 M, reported stocks exceed the estimate (300 M) but are lower than the prior level (310 M). The market sees a modest improvement versus forecasts, yet a slight drawdown from the last period.
• Wheat – Reported wheat stocks (717 M) sit just under the estimate (720 M) and the previous figure (722 M), indicating a small shortfall relative to expectations.
• Cotton – With 4.00 M reported, cotton stocks are marginally above the estimate (3.99 M) but below the prior level (4.10 M), reflecting a near‑flat position and a slight decline from the last report.

Global Interpretation

• Corn – Global end‑stocks match the prior level and are slightly above the estimate, suggesting a modest cushion in world supplies.
• Soybean – End‑stocks are essentially unchanged from the prior period and just below the estimate, indicating a tight global soybean market.
• Wheat – Stocks are unchanged from the previous report and just above the estimate, pointing to a stable but slightly constrained wheat supply.
• Cotton – Global cotton stocks are below both the estimate and the prior figure, implying a marginal tightening in cotton availability.

The August WASDE is traditionally the first report of the season to incorporate survey-based yield estimates rather than trend assumptions, which is why it has historically carried more price risk than the mid-summer editions and why positioning into it tends to be heavier than the print alone would justify. The mix here is the classic split: US corn ending stocks come in well under both consensus and the prior figure, a combination that in past episodes has driven the sharpest knee-jerk moves in the corn contract and pulled spreads tighter, while soybeans print above estimate but below prior, a configuration that has usually faded faster as the market weighs the forecast miss against the sequential drawdown. Wheat and cotton sit close enough to expectations that the established pattern is for them to trade off the corn-led momentum briefly before reverting to their own supply stories. The distinction worth drawing is between the US balance sheet, where corn is the clear surprise, and the global tables, which are essentially unchanged and therefore cap how far the bullish US read travels, since world stocks flat against prior has historically limited follow-through beyond the initial session. What matters next is the usual sequence: whether the trade challenges the yield assumptions underpinning the corn number, how the September revision treats the same balance sheet, and whether export sales data in the intervening weeks corroborate the tighter US picture. As with most WASDE surprises of this shape, the first move is made on the headline delta and the second on the revision risk.
