Corn Starting Tuesday with Weakness

Corn futures and cash were modestly weaker Tuesday, with nearby futures down about 1–1½¢ and the CmdtyView national cash corn at $3.95 after futures pulled off early Monday lows and preliminary open interest rose ~8,625 contracts. USDA reported weekly export shipments of 1.589 MMT (62.32 mbu), down 9.1% from the prior week but up 37.3% year‑over‑year, marketing‑year exports since Sept. 1 at 22.501 MMT (up 68.7% y/y) led by Mexico, Japan and Spain, plus 71,917 MT of sorghum to China and 1.84 MMT of corn sales in the week of Nov. 20. However, managed money flipped to a net short of 10,872 contracts in the week ending Nov. 25 (a 48,999‑contract move to the short side), indicating that despite strong export fundamentals supportive of longer‑term bids, speculative positioning and the modest price pullback could exert near‑term downside pressure and elevate volatility.

Analysis

Corn futures and nearby cash were modestly weaker into Tuesday, with nearby futures down roughly 1–1.5¢ and the CmdtyView national cash corn at $3.95 after contracts pulled off early Monday lows; Mar 26 closed at $4.39 3/4 (down 1¢), May 26 at $4.47 3/4 (down 1 1/4¢) and Jul 26 at $4.53 3/4 (down 1 1/4¢). Preliminary open interest rose by 8,625 contracts on Monday, indicating increased participation even as prices eased.

USDA data show weekly export shipments of 1.589 MMT (62.32 mbu), a 9.07% decline from the prior week but a 37.25% increase versus the same week in 2024, and marketing-year exports since Sept. 1 at 22.501 MMT (885.84 mbu), up 68.74% year-over-year; top weekly destinations were Mexico (488,231 MT), Japan (301,240 MT) and Spain (219,729 MT), and sorghum shipments to China totaled 71,917 MT. Export sales also reported 1.84 MMT in the week of Nov. 20, down from the prior week yet 73.4% larger year-over-year, underscoring resilient demand.

CFTC/backlogged data show managed money flipped to a net short of 10,872 contracts in the week ending Nov. 25—a 48,999-contract move to the short side—which, together with the modest price pullback, suggests near-term speculative pressure and elevated volatility despite strong fundamental export trends. The juxtaposition of robust marketing-year exports and a speculative short bias implies that price direction will likely hinge on incoming weekly USDA export/shipments updates and subsequent positioning flows rather than on a near-term supply shock.

Key Decisions for Investors

• Consider maintaining a modest long or buy-on-dip exposure sized conservatively to reflect strong marketing-year exports (22.501 MMT since Sept. 1) but avoid large outright directional bets given the managed-money flip to a net short and recent price weakness
• Monitor weekly USDA export shipments, export sales and subsequent CFTC managed-money reports as primary triggers to add or trim exposure since these data points are driving the current divergence between fundamentals and positioning
• Employ short-dated downside protection (puts or collars) or smaller-scaled spread trades to manage near-term volatility risk while retaining exposure to the supportive export backdrop
