USDA Grain Stocks Rise – Soybean Exports Still in Question

By: Andrew Catsimanes, Copywriter • Production

USDA Grain Stocks Come in Higher, Raising New Questions

Arlan Suderman, Chief Commodities Economist at StoneX, breaks down the USDA’s September stocks report in his Quarterly Market Outlook. He explains why corn and wheat supplies came in higher than expected and why soybean demand remains the bigger question.

Key Takeaways

  • USDA reports larger wheat and corn stocks than trade expected
  • Suderman says China’s absence leaves soybean exports well below normal
  • Tariffs, uncertain rains in Brazil, and stalled biofuel guidance present ongoing risks for market

USDA Stocks Report Shows Larger Wheat and Corn Supplies

The September 1 USDA stocks report showed bigger wheat and corn supplies than expected. As Suderman noted, the wheat increase partly reflected USDA correcting an August underestimate.

The corn stocks story was a bit more nuanced. USDA raised last year’s crop by 25 million bushels but may still be short. The agency shifted numbers into feed and residual use instead. Suderman said that choice could distort both last year’s and this year’s balance sheets. “Those changes don’t just apply to the old crop, they spill into the new marketing year as well,” he noted.

The September 1 data showed higher stocks for both wheat and corn, while soybeans came in slightly below trade expectations.

Corn and Soybean Demand Outlook Weakens Without China

Suderman pointed to demand as the bigger risk. He called USDA’s corn feed and export numbers “overly aggressive.” Mexico is feeding more cattle, which means U.S. feed use cannot be as strong as USDA projects.

Soybeans are more uncertain still. China has yet to book U.S. soybeans. Suderman projects exports at least 150 million bushels under USDA’s estimate, with the gap potentially widening to 235 million bushels if no trade deal emerges. “Domestic crush capacity can’t cover a shortfall of that size,” he said.

The chart below underscores China’s absence from the U.S. soybean market so far this year, a gap Suderman sees as pivotal for the export outlook.

Tariffs, Brazil’s Weather, and Biofuels Lead Risks

Suderman is also watching three factors outside of supply:

  • A Supreme Court ruling – Justices will decide whether reciprocal tariffs are legal. If overturned, he warned, trade deals could unravel and U.S. leverage with China would weaken.
  • Brazil’s start – Forecasts for Brazil’s planting season are split. Some models show timely rains, others point to dry conditions. “If rains arrive on time, production looks good. If not, we could see trouble,” Suderman said.
  • Biofuel policy remains unresolved – With RVOs and refinery exemptions delayed, Suderman said the soybean oil market has no clear direction.

Wheat and Corn Exports Diverge

Corn exports are running strong, led by Mexico. Soybeans, by contrast, are at a 17-year low. Wheat sales are picking up as lower prices draw buyers back.

Mexico has been the primary driver of U.S. corn export strength this season, with sales running ahead of prior years.

For producers and buyers alike, the latest USDA data provide some short-term stability. Yet as Suderman emphasized, unresolved trade issues, uncertain weather, and delayed policy calls mean the market narrative is far from settled.

Perspective: Morning Commentary for July 21

July 21 – The tech sector led stock futures higher overnight as investors anticipate major tech company earnings reports in the days ahead, while seemingly feeling immune to two wars half a world away that continue to escalate. It’s day #1,609 of Russia’s war on Ukraine, and day #144 of the war with Iran, with neither showing signs of culminating any time soon. These wars are in some of the world’s most critical locations for commodities essential for the global economy, and yet there remains little panic in the U.S. markets at this point. The VIX is trading below 18, while the dollar index trades near 101.0. Yields on 10-year Treasuries are trading near 4.61% this morning, while yields on 2-year Treasuries trade near 4.23%. WTI crude oil is trading near $85, while Brent trades near $91 per barrel. The grain and oilseed sector traded mostly in negative territory overnight after weekly crop ratings largely came in above trade expectations on Monday afternoon.

Perspective: Morning Commentary for July 20

July 20 – Both commodities and stock futures firmed in trade early this morning as we prepare to start a new week. Fighting continues to escalate in both the Middle East and in the Black Sea Region this morning, elevating risks for food and energy commodities, while the U.S. economy continues to show solid growth. The VIX is trading near 18 this morning, which is modestly elevated from where it has been much of this month, but it by no means reflects panic on Wall Street. The dollar index is trading near 100.9 this morning, as it has been trending slowly lower since late June. Yields on 10-year Treasuries are trading near 4.57%, while yields on 2-year Treasuries are trading near 4.20%. WTI crude oil is trading near $82 per barrel after hitting a five-week high overnight, while Brent trades near $88 per barrel. The grain and oilseed markets are firmer, led by soybeans that continue to have strong domestic demand along with steady Chinese buying on the export front.

Perspective: Mid-Day Commentary for July 17

July 17 – Stocks have recovered from their morning lows but remain in the red at midday, with the tech-heavy Nasdaq still leading the way down as it trades 0.8% lower at the time of writing. The VIX remains up roughly 7% on the day to hang around 17.9 at the time of writing, though it is off notably from the three-week high of 19.50 seen earlier in the session. The dollar is trading almost right at unchanged at midday, currently around the 100.75 level. Treasuries are quietly mixed, with 10-year yields slightly in the red just above 4.54% and 2-year yields slightly in the green trading just above 4.17%. Crude oil remains elevated amid the ongoing escalations between the U.S. and Iran, with risk premium coming in ahead of the weekend’s market closure, as nearby WTI current trades up 2.5% on the day near $81.60 and nearby Brent trades up 4.4% on the day near $88.00. The grains and oilseeds are widely higher, with the return of Chinese purchases to the U.S. and the ongoing escalation between Russia and Ukraine impacting shipment through the Black Sea keeping a bid under the market, though the cattle complex continues its recent ugly selloff.
