Some insight from Yra Harris on Futures Radio with Anthony Crudele:
Somewhat paraphrasing:
"If I told you you would have massive carryovers of soybean stocks; Brazil, Agentina, U.S. record crops, and soybean prices were still $9.30/$9.40/$9.50 you would tell me I'm out of my freaking mind. These are times we would be having $4.50-$4.80 beans. That is the dynamic that China has brought to global grain markets."
