U.S. corn was only 55% good or excellent as of June 18, the worst week since 1992 and the lowest for any June or July week since 2012. December corn hit a new yearly high of $6.29-3/4 per bushel on Wednesday, surpassing the prior high of $6.11 set January 3.
Funds have since reduced short positions as weather forecasts brought rain hopes, and December corn and November soybeans fell 1.6% and 2.4% over the last three sessions.
Poor crop conditions threaten yields from a tight old-crop stock base, which supports corn and soybean prices. Forecast rain eased prices short term, but yield risk remains a bullish factor for feed costs.
After 1,079 past bullish weather events, SOY moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
After 1,465 past bullish weather events, CORN moved a median +0.2% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.9% over 20.
Moves of each commodity's benchmark from the last close before the event. Historical reads pool past events of the same kind; they describe what happened, not what will. Not investment advice.
Reuters notes December corn hit a yearly high June 21 then fell as rain forecasts eased weather fears and funds covered shorts, showing the weather premium was being unwound ahead of the period end.
