Corn Futures Commitments of Traders - Week Ending 2026-03-27

Executive summary

This report covers a period of significant bullish conviction among speculators, with Managed Money aggressively expanding their net long position to the highest level in the provided data series. This move was driven by a combination of fresh long entries and substantial short-covering, coinciding with a sustained price rally throughout March. Commercial participants have acted as the primary counterparty, increasing their net short position to a new multi-month high, indicating heavy producer hedging at these elevated price levels. The divergence between speculative and commercial positioning is now at an extreme, suggesting a pivotal point for the market.

Positioning

• Managed Money (Speculators): The speculative net long position surged to +279,630 contracts. This is a substantial increase from +230,888 contracts last week and marks a dramatic reversal from a net short position of -13,234 contracts as recently as late February. The current net long is the most bullish stance observed in the available historical data.
• Producer/Merchant (Commercials): Commercials deepened their net short position to -613,518 contracts, their largest net short of the year. This is a significant increase from -563,874 contracts last week and reflects aggressive selling/hedging into the recent price strength.
• Swap Dealers: This category holds a large net long position of +299,296 contracts, a slight decrease from the prior week. Their position often offsets other financial or physical market exposures and remains a significant source of long-side liquidity.

Flows and week-over-week changes

The reporting week saw a major shift in positioning, driven primarily by Managed Money: - Managed Money: Flipped more bullish by a net +48,742 contracts. This was composed of: - New longs being added (+19,719 contracts). - A significant wave of short-covering, with short positions decreasing by 29,023 contracts. - Producer/Merchant: Increased their net short exposure by 49,644 contracts. This was almost entirely driven by the addition of new short positions (+45,439 contracts), while longs saw a small reduction (-4,205 contracts). - Other Reportables: Reduced their net long position, selling 14,295 long contracts while largely holding their short position flat.

Commercials vs speculators

The classic divergence between commercials and speculators is now at an extreme. - Managed Money has undergone a monumental shift over the past month, moving from a net short position in late February to a very large net long. This indicates a strong belief in further price appreciation. The combination of new longs and short covering points to a high-conviction trend-following move. - Producers/Merchants are taking the opposite view, using the rally to lock in prices for future production. Their short positions now represent 55.7% of total shorts in the market, a dominant share that underscores their role as the primary sellers at these levels. This heavy hedging could act as a cap on further price rallies.

Open interest and participation

• Open Interest (OI): Total open interest increased by 22,925 contracts to 1,796,424. The steady rise in OI throughout March alongside rising prices is a technically bullish signal, confirming that new money is entering the market to support the uptrend.
• Participation: Managed Money now holds 20.2% of all long positions but only 4.7% of shorts. Conversely, Producers/Merchants hold 21.6% of longs but a commanding 55.7% of all short positions.
• Concentration: The market does not appear overly concentrated. The 4 largest traders control 8.9% of the net long positions and 9.7% of the net short positions. The 8 largest traders control 14.8% (long) and 15.0% (short), suggesting a diverse set of participants on both sides of the market.

Price context

The positioning shifts have been closely correlated with market price action. - The reporting period (ending March 27th) saw Corn futures close at 466.25. - This continues the strong rally that began in early March, when prices were trading near 443.00. - The most aggressive phase of Managed Money buying occurred during this rally. For instance, in the two weeks from March 6th to March 20th, Managed Money flipped from a net long of +52,243 contracts to +230,888 contracts, while prices rallied from 453.00 to 468.75. The latest data shows this trend of speculative buying and price appreciation continuing.

Risks and watchpoints

• Crowded Long Trade: The Managed Money net long position is now at an extreme level relative to recent history. This makes the market vulnerable to a sharp correction if the bullish narrative changes, as a rush for the exits could exacerbate any sell-off.
• Exhaustion of Short-Covering: A significant portion of the buying power over the last month has come from speculators covering large short positions. With Managed Money shorts now reduced to just 83,747 contracts (down from over 290,000 in January), this source of buying fuel is diminishing. Future upside will need to be driven more by new long initiations.
• Commercial Resistance: The massive and growing net short position from commercials represents a significant wall of selling. These participants are likely to continue selling into any further strength, potentially capping the rally. The battle between strong speculative buying and heavy producer hedging will be the key dynamic to watch.
