Corn Prices Slip as Traders Wait for USDA Forecasts
Corn prices slipped on Wednesday as traders weighed the risks of Black Sea exports and awaited the US Department of Agriculture's supply-and-demand update, set to be released on Friday.
The most-active CBOT corn contract fell 0.9% to $5.28-3/4 a bushel, according to Reuters.
Grain prices tend to go quiet before major USDA reports as one key number, the expected yield, can reset the entire story.
A small change in yield estimates by StoneX, a commodities brokerage, can still translate into a large swing in total production when multiplied across millions of acres. The firm trimmed its average US 2026 corn-yield estimate to 182.9 bushels per acre from 184.8, which could impact the market's expectations.
Traders are also grappling with mixed signals as USDA crop ratings last week showed 56% of US corn in good-to-excellent condition and 5% had been harvested. Commodity Weather Group expects the Midwest to stay mostly warmer and drier, which can help harvest progress and reduce early-frost worries.
Outside the US, the market is keeping a 'risk premium' in prices for any disruption to Russian and Ukrainian grain flows through the Black Sea, even without fresh breakthroughs in diplomacy. This uncertainty keeps buyers and sellers cautious until the USDA numbers land.
