Really? You believe farmers would continue to produce more wheat than could be sold?
But what would likely happen is livestock feed would switch from corn to wheat, because wheat would then cost less than corn.
And if the ban was like the current crude oil ban? All grades of "raw" feedstock banned?
I was being facetious, but unlike crude oil, wheat can be used for other things besides bread. Crude oil doesn’t spoil, so it can be left in the ground if the prices gets too low, but wheat has to be used or it goes bad, so the product would find it’s way into other market sectors where it wasn’t used before, because it was too expensive, like animal feeds......................
