Grain markets rose in the week to May 17, 2019, with corn and winter wheat making the largest gains while soybeans fell 17-18 cents on Friday. US planting lagged badly, with 30% of corn and 9% of soybeans planted by May 12 versus five-year averages of 66% and 29%.
The US also dropped steel tariffs on Mexico and Canada, and a second round of trade aid was announced.
Severe US planting delays raise the risk of lower corn output and prompt-period price support, while the trade aid and tariff changes add some support to sentiment.
