A USDA Economic Research Service report examines China, US and Brazil interdependence in soybean trade, including price dynamics and market adjustments to China's retaliatory tariff. It notes the US and Brazil supplied 83% of world soybean exports in 2016/17, with China taking 61% of US exports.
The report underlines how concentrated the soybean trade is on China, so tariff changes move US and Brazilian soybean prices. It is background analysis rather than new market-moving data.
After 563 past neutral report events, SOY moved a median -0.1% over 5 sessions (48% higher; middle half -1.7% to +1.6%), and -0.1% over 20.
