China will auction 3.4 million tons of state-stored corn this week, nine times the prior week's volume, including 3 million tons from the three northeastern provinces and Inner Mongolia. Auctions began in April, a month earlier than last year, and last week's sale saw only a small fraction of offered volume transacted.
Heavier state reserve auctions add supply to China's domestic corn market and can pressure local prices, which narrows the gap with import parity and reduces import demand.
After 310 past bearish policy events, Corn moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.6% over 20.
