StoneX’s Mike Castle said the new WASDE was sharply bullish for wheat because US production was cut to a 50-year low, while corn was mostly in line and soybeans are increasingly being pulled into domestic crush and biofuel demand. He also emphasized tightening global stocks, Brazil’s growing dominance in soybeans, China’s lower inventories, and record-strength beef imports tied to strong consumption.

This was a StoneX interview centered on the latest WASDE report and its implications for grains, oilseeds, China trade flows, Brazil competition, and beef. Johanna Bota introduced Mike Castle, StoneX’s senior commodities economist, to explain why the report mattered for markets. Castle said the biggest surprise was US wheat. He described the downward revision as “huge,” noting the 2026/27 US wheat production figure of 1.561 billion bushels came in below even the lowest market estimate. He said the cut was driven almost entirely by winter wheat, especially in the Plains, where drought, freeze damage, and now extreme heat have hurt the crop. On corn, he said the numbers were mostly within expectations. He expected USDA might eventually need to cut feed demand, but the report did not make major changes. On soybeans, he argued the more important story is the shift toward domestic use. …
Near term, wheat looks like the cleanest bullish reaction trade because the USDA cut was extreme and weather risk is still live. Soybeans may trade headline-to-headline around Trump–Xi, but the bigger immediate risk is that the market overprices a Chinese purchase narrative while ignoring Brazil and domestic crush.
Over the next few months, the base case is a tighter US wheat market and a soybean market supported more by crush/biofuel than exports. Confirmation would come from further USDA upward revisions to crush and continued South American strength keeping US beans expensive versus Brazil.
The structural read is that US oilseed markets are shifting from export-led price discovery toward policy-backed domestic value creation, especially through biofuels and crush. Brazil’s scale advantage and China’s strategic stocking behavior reinforce a world where the US wins more on processing and less on raw commodity export dominance.
US wheat production for 2026/27 was projected at 1.561 billion bushels, below even the lowest market estimate.
Host and guest describe the WASDE wheat number as a major miss and the smallest in more than 50 years.
The wheat downgrade was driven mainly by winter wheat problems in the Plains, including drought, freeze damage, and extreme heat.
Castle attributes the cut to weather stress in core winter wheat regions.
US corn and soybean numbers were mostly within expectations, but feed demand may eventually need to be cut.
He says corn was not out of range and expects USDA to reduce feed demand later.
How significant is the downward revision in US wheat, and what's behind it?
Castle said the revision was huge and far below expectations, driven mainly by winter wheat damage in the Plains from drought, freeze events, and extreme heat.
Did corn and soybeans surprise you, or were they in line with expectations?
Corn and beans were mostly in range, but Castle expected USDA eventually to lower feed demand and sees soy demand shifting toward domestic crush and biofuel uses.
How significant is the tighter-than-expected global ending stocks picture?
Castle said global stock tightness matters, but South American production—especially Brazil’s—is the bigger backdrop, and US soybean export competitiveness is weak because US beans are pricier than South American beans.
