Corn
Year-to-date change: 7.5%
The US Department of Agriculture data shows that global corn inventories are at a 37-year low as producers are unable to grow enough grain to keep pace with consumption.
The global grain harvest for the past season was 2.18 billion metric tons, down 2.5% year-over-year. The USDA estimates that the world will consume 2.24 billion metric tons of corn this year.
