Corn Futures Commitments of Traders: Week Ending March 13, 2026

Executive summary

This week saw a seismic shift in Corn futures positioning, characterized by one of the most aggressive bullish rotations by Managed Money seen in recent history. Funds added over 146,000 contracts to their net long position through a combination of massive short-covering and fresh long initiation. This speculative buying spree coincided with a surge in prices and a significant increase in total open interest, suggesting new capital is flowing into the market. Conversely, Commercials (Producers/Merchants) dramatically increased their short hedges, reaching their largest net short position of the observed period, indicating they are using the rally to lock in prices. This creates a stark divergence between bullish speculators and price-taking commercials, setting the stage for significant volatility.

Positioning (net, extremes vs recent weeks)

• Managed Money: Flipped to a substantial net long position of +198,804 contracts. This is a dramatic reversal from a net short of -90,658 contracts in mid-January and marks the most bullish stance for this group over the entire historical period provided.
• Producer/Merchant (Commercials): Deepened their net short position to -514,056 contracts. This is the largest net short recorded in the provided data, indicating a significant increase in producer hedging.
• Swap Dealers: Maintained a very large net long position of +304,874 contracts, nearly unchanged from the prior week. They continue to absorb the substantial short hedging from commercials.

Flows and week-over-week changes

The reporting week was defined by explosive changes in positioning: - Managed Money: Executed a massive bullish shift, increasing their net position by +146,561 contracts. This was driven by the addition of 91,088 new long contracts and the covering of 55,473 short contracts. - Producer/Merchant: Dramatically increased their downside protection, adding 148,324 short contracts while liquidating a negligible 678 longs. This increased their net short position by nearly 149,000 contracts. - Open Interest: Surged by 105,847 contracts. Such a large increase in OI alongside a strong price rally and aggressive speculative buying is a technically bullish signal, indicating conviction and new money entering the long side.

Commercials vs speculators

The market is now defined by a classic standoff between informed and speculative participants. - Speculators (Managed Money) have aggressively bought into the recent price rally, betting on continued upside. Their rapid shift from a large net short to a significant net long highlights a major change in sentiment. - Commercials (Producer/Merchant) have taken the opposite side, using price strength as a major opportunity to sell forward and hedge their physical product. Their net short position of -514,056 contracts stands as a formidable wall of supply at these price levels. - Swap Dealers continue to facilitate this divergence, holding a large net long of +304,874 contracts, effectively warehousing the risk from commercial short hedgers.

Open interest and participation

• Total open interest rose sharply to 1,723,308 contracts, approaching the recent highs seen in February. The 6.5% week-over-week increase confirms that the price action was driven by new positions being established, not merely a shuffling of existing ones.
• Market concentration remains moderate. The largest four traders by net position hold 9.8% of the long side and 8.1% of the short side, indicating that while large players are involved, the positioning is not dangerously concentrated in the hands of a few entities.

Price context

• The positioning data aligns perfectly with the price action. The period covered by the report (March 9 - March 13) saw a sharp rally early in the week, with the front-month contract jumping from the previous week's close of 442.5 to a high of 450.75 before settling the week at 446.0.
• This bullish price action follows a multi-week trend that began in mid-January when prices were near 420.75. That period corresponded with Managed Money's peak net short position (-90,658 contracts), suggesting their subsequent short-covering has been a primary driver of the recovery rally.

Risks and watchpoints

• Crowded Long Trade: The speed and scale of the Managed Money reversal into a large net long position introduces "crowded trade" risk. The market is now more vulnerable to sharp sell-offs if the bullish narrative changes and these new longs are liquidated.
• Producer Selling: The massive commercial net short position could act as a significant headwind for prices. Any further rallies are likely to be met with continued producer selling, potentially capping the market's upside.
• Momentum Signal: The combination of surging open interest, aggressive fund buying, and rising prices is a powerful bullish momentum signal. A key watchpoint is whether this momentum can overcome the heavy commercial hedging pressure. The market is now coiled for a potentially significant trend move, depending on which side capitulates first.
