US durum production this season is estimated to be down more than 7% year over year, the only major variety of wheat to decrease. Projected ending stocks for the year are seen plummeting nearly 30% from a year earlier, dropping to their lowest level since at least 2010. Lower imports are also hitting US durum supplies — in the June-August period durum imports were down 32% versus last year, mainly because of a smaller crop in Canada.
