Bans against bioengineered food ingredients by major food companies have been broadly reported and have been often taken to signal demand shifts away from commodities in favor of identify-preserved non-bioengineered crops.

Neither the Chicago Board of Trade soybean futures prices nor the Tokyo Grain Exchange non-GMO soybean futures prices respond to bans.
