US corn and soybean harvest accelerated sharply in the week ended 4 October, but neither kept pace with its historical seasonal benchmark. Corn reached 23% harvested against a 27% five-year average, while soybeans reached 25% against 33%. Winter-wheat planting was further behind at 36% versus 46% normally. Cotton was the exception, with harvest two points ahead of its five-year pace.
TL;DR
- US corn harvest advanced five percentage points to 23%, but remained four points behind the 27% five-year average.
- Soybean harvest accelerated eight points to 25%, yet remained eight points behind its 33% normal pace.
- Corn maturity reached 83%, exactly matching its five-year average, suggesting the harvest gap is not simply a crop-development problem.
- Soybean leaf drop reached 85%, two points behind the 87% average — a far smaller deficit than the eight-point harvest gap.
- Winter-wheat planting accelerated nine points to 36%, but remained ten points behind the 46% five-year average. Emergence was four points behind normal.
- Cotton harvest reached 23%, two points ahead of its 21% five-year average.
- USDA's 2021–25 averages incorporate imputed 2025 estimates, because the corresponding 2025 reports were cancelled during the federal funding lapse.
- The physical data complicate rather than confirm the late-September speculative de-risking visible in corn and the increasingly bearish positioning in wheat.

Source: USDA NASS Crop Progress, released 5 October 2026 for the week ended 4 October. Because Crop Progress reports for the corresponding October–November 2025 period were cancelled during the federal funding lapse, USDA's 2021–25 averages incorporate imputed 2025 estimates. Five-year averages are the historical share completed by each calendar reference week, so they move substantially week to week during active harvest.
Corn: Mature on Time, Harvest Behind
Corn provides the most useful distinction in this week's report. The share of the crop rated mature jumped from 72% to 83%, bringing development exactly into line with the five-year average, while harvest accelerated five points from 18% to 23%. But harvest itself remains four percentage points behind the 27% five-year pace.
That combination matters. The lag cannot be explained simply by an immature crop waiting to finish development, because nationally maturity has caught up completely. The gap sits between a crop that is ready and the acreage actually harvested.
State data show considerable variation. Illinois advanced from 26% to 36% harvested, Indiana from 13% to 21%, Minnesota from 6% to 12% and Nebraska from 11% to 15%. Iowa moved from 5% to 7%.
This creates a more nuanced backdrop to the latest CFTC positioning. Managed money reduced its corn net long to +381,220 contracts in the week ended 29 September, principally through long liquidation. That positioning move occurred before the latest USDA reference date, so the two datasets should not be treated causally. But the subsequent physical evidence does not provide an obvious harvest-acceleration explanation for the liquidation: harvest remains behind its normal seasonal pace.
Soybeans: Faster Week, Larger Seasonal Gap
Soybeans made more progress during the week than corn, with harvest increasing eight percentage points from 17% to 25%. The comparison with normal progress is nevertheless weaker: the five-year average for this reference week is 33%, leaving the national harvest eight percentage points behind.
Crop development tells a different story. Leaf drop rose from 75% to 85%, only two points below the 87% five-year average. That divergence is the most striking feature of this report. The crop is nearly ready on schedule; it is not coming out of the ground on schedule. A two-point development deficit alongside an eight-point harvest deficit points to field access rather than crop maturity as the binding constraint.
State dispersion supports that reading. Illinois reached 31% harvested, Indiana 27%, Minnesota 25% and North Dakota 34%, while Iowa was only 5%.
The next reports should help distinguish between a temporary timing issue and a more persistent harvest lag. An eight-point national deficit can close quickly during favourable weather, but the relevant question for markets is increasingly whether realised yields and crop quality alter USDA's production assumptions as combines move through more acreage.
Winter Wheat: Planting Is the Largest Deficit
Winter wheat now carries the largest national gap in the report. Planting advanced from 27% to 36%, but the five-year average is 46%, leaving progress ten percentage points behind its normal pace. Emergence doubled from 8% to 16%, yet also remained four points behind the 20% average.
The state picture is uneven. Colorado reached 61% planted against a 74% average, Kansas 24% against 40%, Texas 35% against 48%, while South Dakota was exactly on its 71% average. Washington, at 83%, was ahead of its 74% normal pace.
This matters alongside the latest speculative positioning. Managed money increased its net short in Chicago SRW wheat to −22,109 contracts in the 29 September CFTC data, through both long liquidation and new short selling. Again the reporting dates prevent a causal interpretation, but the physical picture means increasingly bearish fund positioning is occurring alongside, rather than being confirmed by, slower-than-normal US winter-wheat establishment.
Cotton: The Exception
Cotton provides the clearest contrast. Harvest increased from 17% to 23%, putting progress two percentage points ahead of the 21% five-year average, while boll opening reached 74%, slightly below the 76% average.
Unlike corn, soybeans and winter wheat, therefore, cotton's harvest is running ahead of its historical pace. That is consistent with the continued reduction in managed-money cotton exposure, where net length fell to +67,837 contracts in the latest CFTC report as funds both removed longs and added shorts. The timing distinction still applies, but cotton currently presents the cleanest alignment between advancing physical harvest and increasingly defensive speculative positioning.
The Physical and Financial Signals Have Diverged
The useful message from this week's report is not simply that harvest accelerated. It did: corn gained five points, soybeans eight and cotton six, while winter-wheat planting advanced nine points. In isolation those are substantial weekly movements.
But seasonal comparisons tell a different story. Corn harvest remains four points behind normal, soybeans eight behind, winter-wheat planting ten behind and emergence four behind. Only cotton harvest is ahead.
That makes the latest speculative positioning more interesting rather than less. In late September funds were already reducing substantial corn and soybean longs, building bearish exposure in wheat and cotton, and continuing to accumulate soybean meal. The subsequent USDA report does not provide a single physical-market explanation for those moves. Financial positioning and physical crop progress are sending partially different signals.
Outlook
The next Crop Progress report will test whether the current deficits are principally timing effects or beginning to persist.
Corn is particularly interesting because maturity has already reached its normal seasonal level. If harvest accelerates sharply from here, the current four-point deficit could prove temporary. If it does not, the separation between crop maturity and field progress becomes more significant.
Soybeans have further ground to recover. An eight-point deficit is meaningful, although weekly harvest can move quickly at this stage of the season, and the two-point leaf-drop deficit suggests the crop itself is close to ready.
For winter wheat, the ten-point planting deficit deserves monitoring through both planting and emergence rather than being interpreted immediately as a production problem. Establishment conditions after planting will matter more than the calendar alone.
The more consequential fundamental update comes with USDA's October Crop Production release, when harvested evidence begins to feed more directly into national yield and output expectations.
Key Risks
Historical comparison. USDA's five-year averages for this period include an imputed 2025 observation because the corresponding 2025 Crop Progress reports were cancelled. The averages remain USDA's official benchmark but should not be treated as five independently observed weekly readings.
Harvest acceleration. Corn and soybean deficits can close quickly during favourable harvesting weather. Current gaps should not automatically be interpreted as production losses.
Yield versus progress. Harvest percentages measure completed acreage, not realised yield. A slower harvest does not itself imply lower production.
Timing mismatch. CFTC positions are dated 29 September, while the USDA progress data cover the week through 4 October. The USDA release can be compared with positioning but cannot explain retrospectively what funds knew when those positions were established.
Winter-wheat establishment. Slower planting is not equivalent to impaired production. Emergence, soil moisture and subsequent crop condition will determine whether the current timing deficit becomes economically significant.
Intelligence Monitoring Points
- Corn's four-point gap, and whether it closes now that national maturity has reached its five-year average.
- Soybean harvest, recovering from an eight-point deficit, and whether the lag remains geographically concentrated.
- The leaf-drop to harvest spread, currently two points against eight, as the cleanest indicator of field access versus crop readiness.
- Winter-wheat planting, ten points behind normal, over the next two weekly reports.
- Cotton harvest, already ahead of normal, against the continued reduction in managed-money length.
- The October Crop Production report, the next major fundamental checkpoint for corn and soybeans.
FAQ
Is the US harvest behind schedule? For corn, soybeans and winter wheat, yes. Corn harvest is four percentage points behind its five-year average, soybeans eight and winter-wheat planting ten. Cotton harvest is two points ahead.
Did harvest slow down? No. Corn gained five points during the week, soybeans eight and cotton six. The deficits widened because the historical seasonal pace accelerates faster at this point in the year.
Why does soybean leaf drop matter? It measures crop readiness rather than completed harvest. Leaf drop is only two points behind normal while harvest is eight behind, which points to field access rather than crop maturity as the constraint.
Why are the five-year averages unusual this year? USDA's 2021–25 averages incorporate imputed 2025 estimates, because Crop Progress reports for weeks ending 5 October to 9 November 2025 were cancelled during the federal funding lapse.
Does this contradict the recent fund positioning? It complicates it. Managed money reduced corn and soybean longs and built bearish wheat exposure in the week to 29 September, before this report. The physical data since do not supply an obvious confirmation.
What matters most from here? Realised yields rather than progress percentages, and USDA's October Crop Production report, which incorporates harvested evidence into national output estimates.
Data and source note: US crop progress data are from USDA NASS's Crop Progress report released 5 October 2026 for the week ended 4 October. USDA notes that Crop Progress reports for weeks ending 5 October through 9 November 2025 were cancelled because of a lapse in federal funding, so previous-year observations are unavailable for the corresponding weeks and the published 2021–25 five-year averages use observed estimates for 2021–24 together with imputed estimates for 2025. Five-year averages represent the historical share completed by each calendar reference week and therefore move substantially from week to week during periods of active harvest.
