Grains & Sugar Weekly 09/13/2026

Soybeans, corn, wheat and sugar face divergent supply-demand balances, while crowded speculative positioning increases the risk of sharp reversals.

• November soybeans fell 13 1/4 cents on the week to $12.96 1/2 after USDA raised yield to 52.8 bushels per acre and production to 4.535 billion bushels; exports rose 25 million bushels to 1.685 billion, but ending stocks were 12 million bushels above the average estimate at 310 million.
• Chinese buyers purchased roughly 1 million metric tons of US soybeans during the week, while managed money reached a record net long of 257,258 contracts; the Trump-Xi meeting and the $12.71 20-day average are the next key catalysts.
• December corn ended at $5.30 1/4 after USDA cut yield by 2.2 bushels to 178.5 and production by 213 million bushels to 15.800 billion, reducing ending stocks to 1.567 billion bushels and the stocks-to-use ratio below 10%.
• Corn managed money reached a record net long of 414,459 contracts, while harvest was 5% complete and basis weakened; demand remains supportive because EU imports may rise to 25 million metric tons from 19.3 million last year after drought reduced the European crop.
• Wheat prices weakened as Ukraine shipped 630,000 metric tons of farm goods in September, about 60% below normal, and SovEcon cut Russian 2026/27 exports by 7.2% to 41.4 million tons; however, global ending stocks rose to 276.29 million tons and US exports were weak.
• Sugar was supported by constrained Brazilian supply and Asian production risks: Brazil's August exports fell 27.5% year over year to 2.7 million metric tons, Thailand's output may fall at least 17% below 10 million tons, and India is seeking imports despite normally being an exporter.

Takeaway: Commodity prices remain sensitive to geopolitical, weather and energy catalysts, but record-long speculative positions in soybeans and corn and rising sugar positioning leave these markets vulnerable to profit-taking; wheat offers the clearest upside risk if Black Sea logistics deteriorate further.
