Grains & Sugar Weekly

Corn, wheat, sugar and soybeans face conflicting supply, demand and positioning signals, leaving prices vulnerable to sharp moves as upcoming data clarify the balance.

• December corn closed at $4.74 1/4, down 5 1/2 cents for the week, while managed money cut its net long by 83,414 contracts to 246,425; export sales improved to 44.2 million bushels, but seasonal sales remain 32.7% below last year.
• USDA's corn yield estimate is 181.2 bushels per acre versus Pro Farmer's 173.2, while harvest was only 33% complete against a 39% average; stronger cash basis and narrower spreads suggest physical supply may be tighter than USDA indicates.
• December Chicago wheat fell to $6.60 1/2, with US cumulative exports down 32.6% year over year; Russian and Ukrainian supply disruptions have not translated into US demand because Russian Baltic wheat was offered at $268 per ton and Argentina at $238.
• March raw sugar rose 3.0% to 20.85 cents per pound as Czarnikow raised its 2026/27 global deficit forecast to 500,000 tons, but speculative net longs reached 259,549 contracts while physical buyers remained weak.
• November soybeans fell 30 3/4 cents to $12.61 1/4 despite 1.877 million metric tons of announced sales, as September US crush fell 4.5% from August and Conab raised Brazil's crop estimate to a record 181.62 million tons.

Takeaway: Commodity prices will depend on whether corn exports and tight cash markets overcome bearish USDA supply data, whether wheat becomes competitive for overseas buyers, whether rain reduces sugar output, and whether soybean demand can offset record Brazilian production; elevated speculative positions increase downside risk if the expected fundamentals fail to improve.
