Harvest accelerated everywhere last week. It still fell further behind.

Funds, meanwhile, were already heading the other way — and the clearest explanation may lie in China rather than in the fields.

Faster, and Further Behind

Corn gained five percentage points to 23%, soybeans eight to 25%, cotton six to 23% and winter-wheat planting nine to 36%. Those are substantial weekly moves. But the historical pace accelerates faster at this point in the season, so the gaps widened rather than closed: corn is now four points behind its five-year average, soybeans eight, winter-wheat planting ten.

Crop development is close to normal. Harvest is not. Corn maturity reached 83%, exactly level with its five-year average, while soybean leaf drop reached 85% against 87%. The much larger harvest deficits therefore point towards field access and harvest timing rather than unusually late crop development.

Funds, meanwhile, were already heading the other way. In the week to 29 September they removed 31,623 corn longs and 19,867 soybean longs, took Chicago wheat to −22,109 and added 7,621 lean hog shorts. Only soybean meal grew, pushing past 200,000 contracts for the first time.

Friday's Crop Production report is where supply gets tested. The current estimates are 52.8 bushels an acre for soybeans and 4.535 billion bushels of crop.

USDA Crop Progress

Week ended 4 October 2026, released 5 October.

Five-year averages represent the historical share completed by each calendar reference week, so they move substantially during active harvest. USDA’s 2021–25 averages incorporate imputed 2025 estimates, because the corresponding 2025 reports were cancelled during the federal funding lapse.

State harvest, soybeans:

CFTC Agricultural Positioning

Managed money, futures only. Positions as of 29 September 2026.

Soybean meal has now risen from +95,953 on 25 August to +207,578, an increase of 116.3% in five reporting weeks.

Coffee and Minneapolis both reconcile independently to +16,206; the identical figures are coincidental.

Prices

November CBOT soybeans settled at $12.80¾ on 5 October, up 2½ cents, after falling 30¾ cents on 28 September when soybeans were excluded from China’s latest tariff relief. December corn settled at $4.97¼ and December Chicago wheat at $6.92¼.

01 — Friday’s Crop Production Report

Due at 12:00 ET on 9 October. Soybean yield against 52.8 bushels an acre is the number that decides whether the harvest delay is a timing issue or the start of a smaller crop.

02 — Iowa

At 5% of soybeans harvested against a 25% national figure and 34% in North Dakota, one of the two largest producing states has barely started. Whether it catches up determines how fast the national deficit closes.

03 — The Leaf-Drop Spread

Two points behind normal on development against eight on harvest is the cleanest evidence that field access, not crop readiness, is the constraint.

04 — Chinese Private Crushers

State-linked buying continues, but 7.96 million tonnes at 111 crushing plants, negative margins of 120–200 yuan a tonne and a 37.3% Sinograin auction take-up say the commercial sector is not short of beans.

05 — Soybean Meal Past 200,000

The position has more than doubled since late August while beans have become unstable and oil has been sold. It is the one grain or oilseed long still growing.

06 — Whether Wheat Shorts Keep Building

All three wheat contracts saw longs leave and shorts arrive simultaneously, which is a different signal from the de-risking in corn.

The Bottom Line

There are two ways to read a harvest that is moving quickly and falling behind at the same time.

The first is that it doesn’t matter. Harvest progress measures acreage cleared, not bushels produced, and a crop that comes off the field a fortnight late is still the same crop. Corn maturity is exactly on schedule, soybean leaf drop is two points off it, and a dry spell in October would close most of the gap. On that reading, the deficits are weather noise and Friday’s yield number is the only thing worth waiting for.

The second is that the delay is doing real work. Processors in the western Midwest were bidding a dollar a bushel over November futures in late September because beans were not arriving. Old-crop stocks on 1 September were already 3% below last year. A delayed harvest into a tight carry-in produces exactly that kind of nearby dislocation, whatever the eventual national yield turns out to be.

Both are true, and they operate on different timescales. The basis effect is happening now; the yield question resolves Friday.

What makes this week unusual is that the funds were not waiting for either. They cut corn and soybean longs hard in the week to 29 September, before the latest harvest data existed. The physical evidence since has not supplied a clear bearish confirmation: harvest is behind normal, nearby soybean basis has tightened in parts of the western Midwest, and the national yield remains unresolved. Nor does that make the fund move wrong. The clearest explanation may lie less in US supply than in the demand side — particularly China, where state buying continues while private crushers sit on unusually high inventories and show little appetite to chase US cargoes.

If that is right, the soybean question for the rest of October is not only how much the US grows. It is who turns up to buy it.
