USDA’s November 10 crop report cut projected U.S. 2026/27 corn ending stocks by 91 million bushels to 1.758 billion bushels. Yet the same World Agricultural Supply and Demand Estimates report increased projected world corn ending stocks by 1.50 million metric tonnes to 281.94 million tonnes.
That contrast explains why lower U.S. production does not automatically establish a worldwide corn shortage or guarantee a futures rally. Domestic and global balance sheets describe different markets, and demand adjustments matter as much as yield estimates.
U.S. corn versus global corn: the November revisions
| 2026/27 estimate | October | November |
|---|---|---|
| U.S. corn yield, bushels/acre | 181.2 | 179.6 |
| U.S. production, billion bushels | 16.034 | 15.893 |
| U.S. ending stocks, billion bushels | 1.849 | 1.758 |
| World ending stocks, million metric tonnes | 280.44 | 281.94 |
| World ex-China ending stocks, million metric tonnes | 115.31 | 114.99 |
USDA reduced the American crop by 141 million bushels on a 1.6-bushel cut to estimated yield. Lower feed-and-residual use and exports offset 50 million bushels of that lost supply, leaving the 91-million-bushel reduction in ending stocks.
Why the world balance tells a different story
The USDA raised corn production estimates for Argentina and Brazil by 2 million metric tonnes each. Global output is still projected below global use, but revisions to beginning inventories, country-level consumption and trade explain why the projected ending-stock line can move differently from U.S. stocks.
The distribution of inventories matters. Excluding China, USDA's world ending-stock estimate slipped to 114.99 million tonnes. That narrowing buffer for the rest of the world is more relevant to internationally traded corn than an aggregate world number alone.
A tighter balance sheet does not remove price risk
The U.S. stocks-to-use ratio is around 10.8% in USDA’s latest estimate. That offers less cushion against adverse South American weather, stronger export sales or surprise feed demand. However, USDA also trimmed its season-average U.S. farm-price forecast by 10 cents to $4.60 a bushel, underscoring that a smaller crop does not settle the price outlook.
A bullish scenario would require evidence that South American crops disappoint, export demand holds up and the inventory buffer tightens further. A bearish scenario would combine large foreign harvests, lower feed use or weaker import demand with a rebuilding of available export stocks. Neither is established by one month's WASDE release.
Next catalysts for traders and grain buyers
Watch weekly U.S. export sales and inspections, Brazilian and Argentine crop progress, the USDA’s December 10 WASDE and subsequent Commitments of Traders releases. Positioning data should be dated carefully: the widely circulated November 3 COT figures do not represent current holdings as of the November 13 report.
