CBOT soybean futures rose 39.75 cents to 1,226.75 cents/bushel, the biggest one-day gain in four months, after USDA raised production and yield but cut ending stocks to 300 million bushels on strong exports. Domestic coastal soymeal spot prices slipped 10-20 yuan/t, and crushers' soymeal inventories were about 1.35 million tonnes, above the same period of previous years.
Heavy domestic meal stocks and deep livestock losses that reduce feed purchases outweigh the US supply tightening for Chinese meal prices. Soybeans gain on the US balance sheet, while soymeal faces downside pressure from local supply.
After 747 past bullish report events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.1%), and +0.8% over 20.
