Crop Conditions
The 2026 corn and soybean crops entered June in solid shape. Corn Good+Excellent (G+E) ratings held in the 67–68% range through mid-month, while soybeans tracked 65–66%. But the final week of June brought the first meaningful deterioration: corn P+VP climbed to 8% (from 5–6% earlier in the month), and the 6–7 point G+E gap versus year-ago (73–74% in 2025) widened as the season progressed. Soybeans dipped to 65% by week ending June 28, slipping below year-ago levels for the first time this season.
Planting wrapped up efficiently. Corn reached 97% planted and emerged — well ahead of pace at this point last year. Soybeans reached 95%+ planted with 96% emerged. By late June, corn silking had reached 9% nationally. Pollination is now underway.
Corn G+E: 67% (week ending June 28) — down 6–7 points from 73–74% at the same point in 2025. G+E ratings that slip below 65% during pollination are historically associated with meaningful national yield loss — and have triggered sharp price rallies in futures markets.
Weather: The Season's Defining Story
June's weather was the most significant market variable of the season so far. Cumulative growing-season heat units (measured from April 1) finished June at +118% above the 5-year average, while precipitation came in at −47.8% below normal across the Corn Belt.
This is not a passing dry spell. It represents a sustained heat-and-dryness combination that has built steadily over two months — arriving precisely as the corn crop enters its most critical growth window. Heat and moisture stress during pollination is the most bullish price catalyst in the corn market: it directly threatens kernel set and national yield, driving the supply-side shock that sends futures higher.
−47.8% — Corn Belt cumulative precipitation vs. the 5-year average through June 29. Combined with a heat unit surplus of more than double the seasonal norm, the moisture deficit is the single most important variable heading into July.
Exports: A Tale of Two Commodities
Corn exports delivered a standout June. Accumulated shipments through the week ending June 18 ran +28% ahead of last year at the same point in the marketing year. Mexico anchored demand as both the top weekly and year-to-date buyer, with consistent weekly volumes supporting strong physical movement.
Soybean exports told the opposite story. Cumulative shipments ran −19% behind year-ago, reflecting the continued headwind from reduced Chinese buying. Egypt appeared as a notable weekly buyer, but year-to-date soy export volume to China has declined meaningfully. New-crop booking activity has been slow, keeping the soybean balance sheet under pressure.
Corn accumulated exports: +28% YoY · Soybean accumulated exports: −19% YoY. The divergence reflects fundamentally different demand structures entering the 2026/27 marketing year — and sets up very different price risk profiles heading into summer.
Yield Signal — Directional View
As of June 30, AE4cast daily yield models show both corn and soybean yield trajectories trending above the 5-year historical average at the national level. Core Corn Belt states are driving the above-trend reading for corn, while regional variation is significant — pockets of the Southeast and Northern Plains show below-trend signals.
However, the late-June weather deterioration has begun introducing meaningful downside uncertainty. Yield signals are directionally positive entering July, but they are not locked in — the next 3–4 weeks of weather will be decisive.

What to Watch in July
The 2026 crop is at a critical juncture. The next four weeks will largely determine whether above-trend yield signals hold or give way to a tighter supply outlook — and prices reflect it.
Corn — Pollination is the Market
Peak pollination next 2–3 weeks. Watch for any single-week G+E drop below 65% — historically a bullish price inflection point for corn futures, signaling meaningful yield loss risk. Expect elevated volatility around every Monday NASS report.
Price context: corn entered July near 8-month lows (~$4.00/bu on June 29). Today's +10¾¢ weather bounce is the first sign of the market pricing pollination risk — with room to rally toward early-2025 highs near $4.80 if stress persists.
Soybeans — Pod Set Approaching
Still a more forgiving stage than corn, but moisture deficit matters more as August nears. The bigger near-term driver may be demand: any significant Chinese new-crop purchase announcement would be a sharp price catalyst.
Exports — China is the Wildcard
Corn's pace is sustainable. For soybeans, USDA's balance sheet assumes Chinese buying that hasn't materialized. Watch weekly ESR sales (Thursdays) for any sign of re-engagement.
Weather — 6–10 Day Forecasts
The Corn Belt 6–10 and 8–14 day precipitation outlooks will drive price action this month. Any forecast shift toward widespread rains would relieve pressure; continued dryness amplifies the bullish setup.

NASS Acreage Report — June 30
The USDA NASS June Acreage Report (released today, June 30) confirmed corn planted area at 95.3 million acres — essentially unchanged from the March Prospective Plantings. Soybean planted area was revised up to 85.4 million acres (+665,000 acres vs. March intentions). The soybean acreage beat is a modest headwind for new-crop prices on an already-pressured balance sheet.
