Eighteen percent of the U.S. corn crop and 17% of the U.S. soybean crop were harvested as of the latest USDA Crop Progress report, the federal agency confirmed this week.

The two figures mark the first meaningful double-digit cut of the U.S. row-crop harvest season and set the pace that grain traders, agronomists and farmers will benchmark over the coming weeks.

What does the USDA Crop Progress report measure?

The Crop Progress series publishes weekly estimates of planting and harvest progress for the major U.S. field crops, alongside condition scores for what remains in the field. The harvest percentages refer to the share of planted acres cut by the survey date, not to grain delivered, dried or sold. Reports also include topsoil and subsoil moisture ratings across the main producing states.

For corn and soybeans, the series runs from spring planting through to finished harvest, giving the clearest read on how the season is pacing against historical averages.

Why does U.S. harvest progress matter beyond North America?

U.S. corn and soybeans anchor global feed-grain and oilseed supply. When American combines roll faster than expected, more tonnes reach the export pipeline, weighing on Chicago Board of Trade futures and pulling down cash prices in Europe, South America and the Black Sea region. When fieldwork stalls, the reverse happens.

Even percentage-point shifts in the USDA progress figures move elevator basis before they move futures. Analysts treat the weekly print as the cleanest signal of whether the crop is coming off ahead of, on, or behind the five-year average pace.

How should arable farmers read this update?

For growers pricing the current harvest or selling forward into the next marketing year, three metrics in the same USDA report drive the read:

• Harvest progress — the 18% corn and 17% soybean figures released this week.
• Crop condition — the share of uncut acres rated "good" or "excellent", which sets the yield ceiling for what remains in the field.
• Topsoil moisture — a proxy for how many combining days the next week will allow.

A fast, clean harvest with stable condition ratings drags prices. A slow harvest, a deterioration in ratings, or dry soils lifts them.

How is the report built?

USDA's Crop Progress estimates come from weekly surveys of extension agents, Farm Service Agency staff and farmers across the main producing states. The data run from April through November, with state-level breakdowns published alongside the national figures. Condition ratings use five categories — very poor, poor, fair, good, excellent — and condition shifts of three to five percentage points typically draw analyst commentary.

What comes next?

The next two USDA Crop Progress reports will determine whether this week's 18% and 17% mark the start of a rapid run-off or a slower-than-average finish.

Watch the spread between this week's progress and the five-year average. Watch condition ratings for any slide in the northern Corn Belt, where late-planted fields carry the highest frost risk. And watch elevator basis, which adjusts before futures react. The next USDA Crop Progress report lands next week.
