The IGC forecast the 2017-18 global corn crop at 1.025 billion tonnes, down one million tonnes from last month estimate and well below the prior season 1.069 billion. Downward revisions for corn crops in China (213.2 million tonnes from 215.2 million) and the European Union (60.2 million from 61.0 million) were partially offset by an improved outlook for production in Argentina (41.8 million from 39.8 million).
