Prospex*Agro reviewed the September WASDE, noting global ending stocks for wheat, corn and soybeans all came in above trade expectations. USDA raised 2026/27 global wheat production by more than 3 MMT, led by Australia.
A looser global wheat balance from larger exporter crops adds bearish pressure on wheat, while corn and soybean surprises are smaller relative to their tighter balances.
After 1,006 past bearish report events, Wheat (SRW) moved a median +0.0% over 5 sessions (50% higher; middle half -1.6% to +1.8%), and +0.3% over 20.
After 770 past neutral report events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.1% to +1.6%), and +0.7% over 20.
After 563 past neutral report events, Soybeans moved a median -0.1% over 5 sessions (48% higher; middle half -1.7% to +1.6%), and -0.1% over 20.
