US corn futures extended their rally to a four-month high on May 17, 2019, on forecasts of heavy Midwest rain that would worsen planting delays. Wheat touched a six-week high on excess moisture concerns for spring wheat sowing, while soybeans fell sharply.
Planting delays and possible acreage shifts from corn to soybeans shape feed-grain supply expectations. Wet conditions also raise wheat disease risk, supporting feed-grain prices.
