Corn (CBOT): Contract, Supply and Price Drawdown

Feed, food and ethanol. The contract it trades on, who produces it, the figures its price is set against, how to get exposure, and how far its price fell from its highs in five years.

Verified figures, not advice. Contract terms, production, stocks and fund costs come from the exchange, government agencies and fund issuers named beside each figure, read on 14 Oct 2026. A figure we could not verify is shown as "not verified"; a figure we worked out ourselves is marked "computed". We do not say where a price is going or whether to buy. Commodity funds and futures can lose more than you expect. Found a mistake? Tell us and we correct it.

Step 3. The figures the price is set against

Price alone does not say whether a commodity is dear or cheap. Stocks, balances and costs show how tight or loose the market is. We list them as published, with the date.

Step 4. What moves the price

  • US yield and crop size: USDA projects a 2026/27 yield of 181.2 bu/acre (186.5 in 2025/26) and production of 16,034 vs 16,964 mil bu. (usda.gov)
  • Stocks: US ending stocks fall to 1,849 mil bu (from 2,095) and world ending stocks to 280.44 Mt (from 307.16), tightening the supply cushion. (usda.gov)
  • Supply is concentrated in the US, China and Brazil (about 66% of world output, computed), so weather in these regions drives world prices. (usda.gov)
  • Production costs: ERS total costs listed for US corn were $900.52 per planted acre in 2025, framing the margin against the $4.70/bu projected farm price. (ers.usda.gov)

Step 5. How far the price has fallen from its own highs

-11.9%Change, 5 years
-53.8%Deepest fall
not yetMonths to recover
-38.8%Now vs highest month-end

From Oct 2021 to Sep 2026 the front-month futures price of Corn (CBOT) changed by -11.9%. The path matters as much as that end result: the deepest fall below a previous high was -53.8%, from Apr 2022 to Aug 2024 (28 months).

It has not climbed back to that earlier high.

At the end of Sep 2026 it was 38.8% below its highest month-end (Apr 2022).

Time spent more than 20% below its high: 44 of 60 months.

Among the 14 commodities with a chart here, the median deepest fall was -49.0%. Corn (CBOT) ranks 4 of 14 from deepest, so its fall was deeper than the median.

A second, independent series (IMF maize price, US No.2 yellow Gulf, monthly average to Jul 2026 (via FRED); monthly average, to Jul 2026) gives a deepest fall of -51.4%, a gap of 0.9 points from ours, with the low point 0 months apart. We take the two as agreeing.

How we made this: month-end settlement prices of the front-month futures contract from Yahoo Finance, read on 14 October 2026, checked against a second source as described above. A front-month series jumps when the contract changes, so it is not the return of any fund. The figures and the chart are our own calculation; we do not republish the raw prices.

Step 6. How to get exposure

Futures roll. Teucrium's prospectus says that in contango the fund sells cheaper near contracts and buys dearer later ones when rolling, which can reduce NAV and total return (prolonged contango could have a significant negative impact), while backwardation can benefit returns. (teucrium.com)

Corn prices are strongly seasonal and weather-driven, and futures-based funds such as CORN can diverge from spot corn through roll costs, and their low net expense ratio reflects a fee waiver the sponsor can end.

What we could not verify

  • USDA-published stocks-to-use (not stated for corn in WASDE; 11.3% is computed)
  • ERS total cost per bushel (not published as a row)
  • Corn contract months/grade from CME fact card (undated); CBOT corn rulebook chapter could not be fetched
  • Corn contract spec page on cmegroup.com is JS-rendered and returned no values

A price move says what buyers paid, not what the commodity is worth. For what we mean by value, see What is value?

Questions people ask

What moves the price of Corn (CBOT)?

US yield and crop size: USDA projects a 2026/27 yield of 181.2 bu/acre (186.5 in 2025/26) and production of 16,034 vs 16,964 mil bu.

How can I get exposure to Corn (CBOT)?

Through futures on CBOT (CME Group), or through funds and exchange-traded products. Step 6 lists the ones we verified, with structure and cost. Funds that hold futures can differ from the spot price.

Why can a fund differ from the price I see?

A fund that holds futures must sell contracts about to expire and buy later ones. When the later ones cost more (contango) each roll can cost money; when they cost less it can add. So its return is not the spot price.
