Wheat farmers in several exporting countries are refusing to sell their crops at prices close to four-year lows, leading to dwindling supplies and potential price spikes for flour makers. Grain processors, who typically buy wheat three to four months in advance, have limited supplies, leaving them vulnerable to any production shortfall. Farmers are hoarding their crops as global wheat prices have fallen due to solid production in Australia and Argentina, and improving growing conditions in key exporting regions. This situation could lead to food inflation as global stockpiles are already projected to hit a nine-year low.
