Corn Funds Cut Exposure Before USDA Raised Supply

Managed Money was already reducing its corn exposure before the October WASDE delivered a substantial increase in projected US ending stocks. The subsequent Crop Progress report showed harvesting falling further behind its normal seasonal pace, despite corn maturity reaching its five-year average.

The CFTC’s 6 October positions showed funds reducing their corn net long by 51,381 contracts to 329,839. Of that reduction, 46,594 contracts came from closing existing longs rather than opening new shorts. Net length has fallen by 84,621 contracts since mid-September, when it stood at 414,460.

Three days later, USDA raised projected 2026/27 corn ending stocks by 282 million bushels to 1.849 billion. Production increased by 234 million bushels, while beginning stocks rose by 173 million. Total supply increased by 407 million bushels, partly offset by a 125-million-bushel increase in projected use. December corn briefly traded at its downside limit before closing approximately 4.1% lower.

The Crop Progress release on 13 October added a different consideration. Corn harvesting reached 33%, up ten percentage points, but the five-year average advanced twelve points, widening the deficit from four to six. Maturity reached 91%, matching its historical pace. The crop is developing on schedule, but harvesting remains behind.

The timing matters. The 6 October CFTC snapshot predates both USDA releases, so the reduction in fund exposure cannot have been a response to their contents. Friday’s next positioning report will provide the first indication of how funds responded to the larger corn balance sheet and subsequent price decline.

Soybeans present a contrasting picture. Managed Money added 11,508 contracts of net length, USDA increased projected ending stocks by only five million bushels, and harvesting advanced 21 percentage points to 46%, narrowing its deficit against normal from eight points to four. The soybean balance sheet changed comparatively little, while harvest progress improved substantially.

01 — The Next CFTC Vintage

The 6 October positions predate both USDA releases. Friday’s report covers positions to 13 October and is the first to capture any response to the WASDE and the subsequent corn decline.

02 — Corn’s Harvest Deficit

Six points behind with maturity at normal. The gap is now about completed acreage rather than crop readiness, and further weekly gains have to exceed the seasonal advance to close it. Iowa at 14% against a 34% average is where the shortfall is concentrated.

03 — Whether Soybeans Keep Buying

Funds added 9,067 gross longs on 6 October, ahead of a WASDE that raised carryout by only five million bushels. The soybean balance-sheet revision was much smaller than corn’s, while funds continued adding net length.

04 — Sugar’s 30,758 New Longs

The largest positive positioning change among the twelve, taking net length to 252,514 contracts. The additional longs account for approximately 90% of the 34,178-contract increase in net length, rather than of total long exposure.

05 — Winter Wheat Establishment

Planting improved from a ten-point deficit to seven, but emergence widened from four to five. The two measures should converge as recently seeded acreage develops.

06 — Cotton’s Two Signals

Harvesting two points ahead of normal against 36% of the crop rated poor or very poor, with Texas at 52% and Oklahoma 67%. Funds have meanwhile cut net length 10,719 contracts, almost entirely through long liquidation.

The Bottom Line

The corn market received three separate readings in the space of five days, each measuring something different.

The chronology matters: the reported fund liquidation preceded both USDA releases. Net length had fallen by 84,621 contracts since mid-September, and 46,594 gross longs were closed in the reporting week alone. By the time USDA published a 282-million-bushel increase in projected ending stocks, Managed Money had already reduced its position by roughly a fifth.

That does not diminish the WASDE. The figure landed approximately 172 million bushels above the pre-report trade estimate, and December corn briefly reached its downside limit. But a market in which speculative length has been falling for three weeks is differently positioned for a bearish surprise than one in which it has not, and the remaining net long of 329,839 contracts is still substantial.

The harvest data measure something else again. Corn is mature on schedule and six points behind on fieldwork, which concerns the timing of physical supply rather than its quantity. Crop Progress reports harvested acreage, not yield, and a delayed harvest is not evidence of a smaller crop.

Soybeans provide the contrast. Funds added net length, the balance sheet changed little, and harvest progress recovered sharply against its seasonal benchmark. The same week and the same releases produced a materially different picture.
