US Corn Market Lifted by Record Export Sales, But Questions Linger

U.S. corn futures are drawing fresh support from a surge in confirmed export demand, with USDA weekly export sales and additional flash deals to Mexico triggering a broad rally across grain markets. Record weekly net sales for the 2026/27 marketing year underscore that global buyers are returning to U.S. origins despite intense competition from South America. The price rebound at the end of the week, led by December corn, comes after earlier losses and highlights how sensitive the market is to concrete demand signals. Strong sales to Mexico and other key destinations signal that U.S. export programs are gaining traction early in the marketing year, even as overall commitments remain below past benchmarks. At the same time, a firm U.S. dollar, large Brazilian supply projections and lingering macro and energy uncertainty continue to cap upside potential and keep attention firmly on follow‑through demand in the weeks ahead.

Prices

Chicago December corn futures closed on Friday, November 13, 2026 at around $4.45 1/2 per bushel, up 3 cents on the day and modestly higher on the week, with resistance seen near $4.50–4.55 and support around $4.38–4.40. AgroLatam and other trade commentators highlight that the move reversed part of Thursday’s setback and was driven largely by the export sales news rather than a fundamental shift in supply.

The rally spilled over from soybeans and wheat, where futures also firmed on the back of robust export data and additional daily sales. However, traders note that despite the strong weekly figure, corn export commitments still trail typical seasonal progress, which limits the willingness of funds to chase prices much beyond nearby resistance zones.

Supply & Demand

The latest USDA weekly Export Sales report showed U.S. corn net sales for 2026/27 at roughly 2.88 million metric tons, plus about 594,000 metric tons for 2027/28, a marketing‑year high that exceeded pre‑report expectations and confirmed the tone set in the futures pit. Mexico dominated buying, accounting for the bulk of the volume, complemented by solid interest from Colombia and South Korea, underlining the depth of demand across key feed grain importers.

Beyond the weekly tally, a series of separate "flash" announcements added another roughly 303,000 metric tons of corn sales to Mexico for 2026/27 (plus a smaller 2027/28 component), reinforcing the perception that importers are actively locking in U.S. supplies at current price levels. Still, cumulative commitments are estimated at only about one‑third of USDA’s full‑year export target, slightly behind the five‑year average pace, so sustaining current momentum will be crucial if exports are to meet projections.

On the supply side, U.S. harvest is largely advanced, and attention is shifting to global competition. Brazil’s CONAB has kept its 2026/27 corn production forecast high near 148 million metric tons while trimming expected exports to 43 million metric tons, signaling ample supplies but some constraint on outbound flows. Ukraine’s potential reduction in sowing area next spring due to export logistics issues could tighten Black Sea competition later, though this remains a forward‑looking risk rather than an immediate driver.

Fundamentals & Key Drivers

• Export sales momentum: Combined old‑ and new‑crop sales around 3.48 million metric tons for the latest week mark the strongest performance so far in the 2026/27 campaign and validate the recent uptick in futures.
• Mexico’s central role: Mexico remains the anchor buyer, with more than two‑thirds of weekly sales and sizeable outstanding commitments, ensuring a solid base load for U.S. Gulf and rail logistics.
• Lagging cumulative exports: Despite the strong week, total commitments stand well below last year’s level at this stage, prompting USDA to trim its 2026/27 corn export projection in the latest feed outlook and WASDE.
• South American competition: Large Brazilian crop prospects and still‑competitive offers from the Black Sea region act as a cap on U.S. export price ambitions, particularly for more price‑sensitive Asian buyers.
• Macro and currency factors: A relatively firm U.S. dollar and uncertain energy prices continue to shape importers’ timing and could blunt some of the positive impact from USDA’s export numbers if financial conditions tighten.

Weather & Crop Conditions

Weather is currently a secondary driver for U.S. corn compared with export demand, as the 2026 harvest is mostly complete. Short‑term U.S. Corn Belt forecasts point to seasonally cooler, drier conditions, which favor remaining fieldwork and logistics rather than altering yield outcomes. Internationally, attention is turning to South American weather, where Brazilian rainfall patterns over the next several weeks will be closely watched for any impact on the large crop now expected by CONAB.

Trading Outlook (Next 1–2 Weeks)

• Producers: The recent export‑driven bounce toward resistance around $4.50–4.55 in December futures offers a window to incrementally scale in sales or add short‑dated hedges, especially where on‑farm stocks are heavy and basis has recently improved.
• End users: Feed buyers may consider extending coverage modestly on breaks back toward the $4.38–4.40 support area, recognizing that any further upside surprise in export data or South American weather could tighten nearby supplies and lift basis.
• Speculative traders: Momentum has turned constructive but remains fragile; strategies favor buying dips rather than chasing strength, with tight stops below recent lows given lingering headwinds from large global supply and macro uncertainty.
