Analysis notes soyoil stocks rose above estimates, but the soybean oil market may have overreacted to biofuel mandate changes. The 2017 advanced biofuel volume of 4.28 billion gallons may be filled largely by excess biodiesel, requiring roughly 577 million wet gallons.
Biodiesel RIN mechanics imply strong demand for soyoil to meet the advanced category, supporting soyoil prices. Any shortfall in cellulosic or other qualifying supply shifts demand onto biodiesel.
