Crude oil fell below $30/barrel and sterling hit a 35-year low against the dollar on 18 March 2020 as the pandemic hit growth and transport demand. Global wheat fell through February and early March then rallied in the third week of March, while maize stayed low as weak crude discouraged ethanol use.
Low crude reduces ethanol demand for maize and cuts DDGS output, keeping feed grain prices soft, while the weaker pound affects UK feed import costs.
