Chicago March corn was stable at about $167/t from December 7 to 11, with the USDA December report leaving the US balance sheet unchanged. Dry weather in Brazil and Argentina cut crop projections, with CONAB lowering Brazil's safra maize estimate to 24.1 Mt.
South American production losses and strong Chinese import demand support export prices for corn and related feed grains.
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.
