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: Morning Commentary for August 11

August 11 – It was generally a quiet night for the markets until early this morning when a headline hit that Iran and Oman were close to reaching a deal. Stock futures rallied, while the dollar index followed Treasury yields lower, along with active selling in the energy- and food-based commodities. The headline had limited impact though in a world that has become skeptical of promises of peace. Stock futures remain steady to firmer at this hour, while the VIX trades near 16 – just above 2026 lows. The dollar index is trading near 99.8 this morning, after recovering from its early morning selloff over the following hour of trade. Yields on 10-year Treasuries are trading near 4.69%, while yields on 2-year Treasuries trade near 4.22%. WTI crude oil is trading near $82 per barrel at this hour, while Brent trades near $88. The grain and oilseed markets are mostly weaker, after failing to recover from this morning’s early selloff that started in the crude oil market.

Perspective: Mid-Day Commentary for August 10

August 10 - Stocks traded quietly mixed to weaker through much of the morning as investors weigh Middle East war / peace headlines with artificial intelligence concerns / opportunities. Ironically, the VIX is trading near 15, putting it just barely above 2026 lows, despite the high level of geopolitical risks and AI concerns. The dollar index continues to consolidate largely between 99.5 and 100.0 after the late July break in what appeared to be Japanese central bank currency intervention. Yields on 10-year Treasuries are trading near 4.70%, while yields on 2-year Treasuries are trading near 4.24%. WTI crude oil is trading near $81 at this hour, while Brent trades near $87 per barrel on the geopolitical risks. The grain and oilseed markets are mixed ahead of Wednesday's big USDA WASDE crop report.
