Wheat
Year-to-date change: -1.2%
The Middle East-North Africa region buys 32% of global grain shipments and Egypt is the world's largest wheat importer. Violence and riots in the area will curb demand for soft commodities, which is why corn, wheat, and soy were down last week.
On the supply side, India announced last week that it may permit wheat exports as the country may harvest a record crop this season.
