Corn Futures Rally on Dry Forecast; Export Sales Signal Resilient Demand

Corn futures maintained upward momentum in the Thursday session, bolstered by drier weather forecasts that threaten crop yields across key growing regions. As markets price in a weather risk premium, the national average Cash Corn price climbed 2 cents to settle at $4.34 1/2, reflecting the tense supply outlook.

Export Data Reveals Robust Appetite

Data released this morning indicates that global demand remains more resilient than anticipated, providing a floor for prices despite pressure on deferred contracts. The breakdown of sales highlights key destination shifts:

■Old crop sales totaled 332,679 MT for the week of July 16, marking a slight increase from the prior week.

■Mexico emerged as the dominant buyer with 203,300 MT, followed by Taiwan securing 152,000 MT.

■New crop sales surged to 701,505 MT, ranking as the fourth-largest sale for the marketing year, though down 4.4% year-over-year.

■Unknown destinations accounted for 168,000 MT, while Colombia purchased 148,100 MT.

Weather Patterns Tighten Supply Estimates

The National Oceanic and Atmospheric Administration (NOAA) 7-day forecast paints a concerning picture for producers, with precipitation expected to be scarce across the vast majority of the corn belt. This lack of moisture is critical as crops enter sensitive development stages:

■Only Southwest Nebraska, Northern Missouri, and Eastern Kansas are expected to see 1 to 2 inches of rain.

■The remainder of the growing region is forecasted to remain fairly dry, sustaining support for prices.

Futures Curve Dynamics

While front-month contracts held onto gains, the curve shows slight softness in deferred 2027 contracts, indicating some uncertainty about long-term demand:

■September 2026 Corn (Sep 26) closed at $4.64, up 2 cents.

■December 2026 Corn (Dec 26) settled at $4.87 1/2, gaining 2 3/4 cents.

■March 2027 Corn (Mar 27) finished at $5.03, up 2 3/4 cents.

■New Crop Cash prices were reported at $4.38 1/2, up 2 cents.

From an Emerging Markets desk perspective, the rally in corn is significant beyond just the agricultural pits. For net food-importing EMs, sustained price levels above $5.00 could exacerbate food inflation pressures, complicating the monetary policy easing cycle we are witnessing in parts of Asia and LatAm. Mexico's heavy buying spree suggests regional supply tightness that could ripple through broader trade balances. We are watching the $5.03 level on the March '27 contract as a critical technical resistance point.
