Wheat And Soybean In September: Caught In The Crossfire Of Regulation, Geopolitics And Tariffs

U.S. soybean output remains stable, but domestic crushing is projected to reach record levels, with over 53% of soy oil directed to biofuels due to fiscal incentives, leading to an 11-year low in U.S. exports and a slight price dip to $10.00/bushel. Conversely, the global wheat market enters 2025/26 with a comfortable supply outlook, as near-record global production of 816 MMT and rising world ending stocks (264.1 MMT) have pushed U.S. wheat prices to multi-year lows of $5.10/bushel, fostering increased feed usage despite persistent U.S. winter wheat drought. This divergence highlights how policy shifts and robust global supply are significantly impacting agricultural commodity dynamics.

Analysis

The global agricultural commodity markets for wheat and soybeans exhibit divergent fundamentals entering Q4 2025. The soybean market is characterized by a significant structural shift in U.S. demand, where stable domestic production of 4.30 billion bushels is meeting record domestic crushing. This is driven by new fiscal incentives for renewable fuels, which are projected to consume over 53% of U.S. soybean oil. This policy-driven demand has curtailed U.S. export forecasts to an 11-year low of 1.745 billion bushels, leading to a modest increase in ending stocks to 300 million bushels and a slightly lower projected farm price of $10.00/bushel. Despite late-season drought affecting 22% of U.S. acreage, the impact was mitigated by cooler temperatures and is offset by a record Brazilian harvest. Conversely, the wheat market is defined by a global supply surplus. Near-record global production, forecast at 816 MMT, is pressuring prices significantly. Upward revisions to harvests in Australia (34.5 MMT), the EU (140.1 MMT), and Russia (85 MMT) have pushed Chicago wheat futures to five-year lows and the U.S. season-average price down to $5.10/bushel. This price weakness is spurring increased wheat-for-feed demand globally. While drought remains a concern for 38% of the U.S. winter wheat area, the overwhelming global supply has improved U.S. export competitiveness, though U.S. ending stocks are still projected to tighten to their lowest level since 2014 at 844 million bushels.

Key Decisions for Investors

• Monitor U.S. soybean crush margins and renewable fuel policy developments, as these are now the primary drivers of domestic demand, supplanting the influence of traditional export markets.
• Given the near-record global wheat supply and multi-year low prices, a bearish or neutral stance on wheat is warranted, as abundant production from key exporters will likely cap significant price rallies.
• Consider relative value trades, such as long soybeans/short wheat, to capitalize on the diverging fundamentals where U.S. biofuel policy provides structural support for soybeans while a global surplus pressures wheat prices.
• Investors should closely track soil moisture for the U.S. winter wheat planting and the developing El Niño's impact on South American soybean sowing, as these weather factors represent the primary upside risks to the current supply outlooks.
