Larger global production of grains and oilseeds in response to higher prices in recent years has increased world supplies of corn, wheat, and soybeans. At the same time, income growth in developing countries has weakened and the U.S. dollar has strengthened, affecting both global agricultural demand and U.S. exports, resulting in lower near-term prices for those crops.
Longer run developments for global agriculture and U.S. trade reflect steady world economic growth, population gains, and continued global demand for biofuel feedstocks. Those factors combine to support longer run increases in consumption, trade, and prices of agricultural products. Thus, following the near-term declines, moderate prices gains are projected over the next ten years.
