US Corn Conditions Suffer Sharpest Deterioration In Three Years, Fueling Food Inflation Fear

Less than a week after we reported that an options whale placed a $20 million bet on corn futures, a new U.S. crop report revealed the sharpest weekly deterioration in conditions in three years.

Bloomberg cites a new USDA report that rated 63% of the U.S. crop as good or excellent, down 4 percentage points from the previous week and below consensus estimates. The decline was due to heat and dryness battering some of the nation's top agricultural growing belts.

The most-active contract gained as much as .9%.

Heat warnings plague parts of Illinois and Missouri, although Corn Belt weather is expected to improve later this week.

Last week, an options trader made a $20 million bet that corn futures will surge to their highest since 2023, as reduced U.S. planting, record exports, and heat-damaged crops tighten the supply outlook. The trade involved 105,000 November $5.50/$6 call spreads, equivalent to more than 500 million bushels.

The Bloomberg Agriculture Spot Index (BCOMAGSP) recently hit a three-year high. This dollar-denominated benchmark tracks 10 major agricultural futures, including Chicago and Kansas City wheat, corn, soybeans, soybean meal, soybean oil, coffee, cocoa, sugar, and cotton.
