All Eyes on Friday's WASDE Corn & Soy Yield Update

All Eyes on Friday's WASDE Corn & Soy Yield Update

Bertrand Oesterle, StoneX VP of Clearing and Execution Sales, sets out what to watch in the September 12 WASDE report and how it may shape harvest and stocks.

Key Takeaways

  • U.S. corn and soybean yield outcomes steer headline risk
  • China buying favors South America while U.S biofuel demand stays firm
  • Wheat dynamics reflect Russian pricing and evolving European factors

USDA yield shifts could reset market tone

The report focus is on updated U.S corn and soybean yields after record August figures and recent weather and disease concerns. Crop condition readings eased with corn at 68 percent good to excellent and soybeans at 64 percent, still above five-year averages. Recent surveys point to more modest changes than early chatter suggested, so attention stays on how far USDA moves.

China absence and biofuel demand reshape stocks

If yields are trimmed, production and stocks could fall. Pre-report views point to only modest stock adjustments, complicated by China’s absence from U.S. soybean purchases despite strong August import volumes. Market participants note that U.S. biofuel demand remains firm, which could lean U.S. ending stocks lower even if exports lag.

Harvest momentum and oilseed surprises across regions

U.S. corn harvest has begun with early progress and warm dry weather expected to help pace, potentially pressuring prices. Outside the U.S., Ukraine’s corn harvest is starting with output indications within a high twenties to low thirties range, Brazil’s first corn planting is underway, and French maize conditions have held steady in recent weeks with EU outputs revised into a lower band than early season hopes.

In oilseeds, Canada’s canola harvest shows good quality on initial cuts with around a tenth of area harvested and indicative yields consistent with market talk. In Ukraine, winter rapeseed planting is underway after beneficial rains, while a newly applied export tax is reported to be causing paperwork issues that could slow shipments.

Russian exports and euro strength weigh on wheat

Wheat updates include fully planted fields in Argentina with some areas seeing heavy rain, U.S. winter wheat planting commencement, and Ukraine’s recently harvested crop tally improving with increased winter area plans. Russia’s production estimates have edged higher while reported export prices have eased.

Paris wheat remains influenced by multiple factors. Lower Russian offers add pressure, but expiry mechanics on the front contract and expectations for a consolidation phase also feature, alongside currency considerations as euro moves remain a key concern for exporters and producers.

Perspective: Mid-Day Commentary for August 7

August 7 – Stocks are looking to end a strong week on a strong note, with the major indexes all in the green at the time of writing. The VIX touched a nearly seven-month low earlier in the session and remains muted as it hovers just below the 15-mark as this morning’s ugly labor market data helps ease hawkish Fed jitters. The dollar has rebounded from its nearly two-month low earlier in the session but remains in the red on the day, trading at 99.55 at the time of writing. Treasuries have had a very volatile day, with yields tanking following this morning’s Non-Farm Payrolls release but bouncing back into midday, with 30-year yields now trading at 5.209%, 10-year yields trading at 4.654%, and 2-year yields trading at 4.204%. Crude oil has risen from the morning lows as traders eye the weekend market closure for potential geopolitical developments, with nearby WTI now down only 0.2% on the day to trade around $78.10 and nearby Brent breaking into the green, up 1.25% on the day to trade above $83.50. The ags are largely mixed, with the grains and oilseeds mostly in the green, save for a mixed picture in the soy complex, while live and feeder cattle futures move in opposite directions, with the former adding to yesterday’s sharp losses and the latter attempting a rebound.

Perspective: Morning Commentary for August 7

August 7 – The U.S. economy unexpectedly lost 23k jobs in July, dramatically below market expectations of an 80k increase and marking the worst Non-Farm Payrolls print since February. Furthermore, May and June were both revised sharply downward, with combined revisions showing 103k fewer jobs than previously reported. Outside of the healthcare sector, which added 22k jobs in July, the losses were very broad-based. Government payrolls saw the largest decline, shedding 53k jobs in July, the largest seen since October 2025, while June was revised down to show a loss of 10k jobs as well. The private sector at least saw growth, adding 30k jobs in July, now matching the month prior after it was revised down from the 49k initially reported, and substantially missing forecasts of 78k jobs being added. This is a sharp reversal in course from the largely better than expected U.S. labor data seen earlier this week.
